You may want to alter this if you want this entity to always appear in front of other objects, e.g. for a 3D menu system or such.

## Detailed Description

Class defining particle system based special effects.

Remarks:
  Particle systems are special effects generators which are based on a number of moving points to create the impression of things like like sparkles, smoke, blood spurts, dust etc.

  This class simply manages a single collection of particles in world space with a shared local origin for emission. The visual aspect of the particles is handled by a ParticleSystemRenderer instance.

  Particle systems are created using the SceneManager, never directly. In addition, like all subclasses of MovableObject, the ParticleSystem will only be considered for rendering once it has been attached to a SceneNode.

Reimplemented from Ogre::MovableObject.

virtual void Ogre::MovableObject::_notifyManager | ( | SceneManager * | man | ) | `[virtual, inherited]`

| Notify the object of it's manager (internal use only). Definition at line 168 of file OgreMovableObject.h.

virtual void Ogre::MovableObject::_notifyMoved | ( | void |  | ) | `[virtual, inherited]`

| Internal method called to notify the object that it has been moved. Reimplemented in Ogre::Light.

void Ogre::ParticleSystem::_notifyOrigin | ( | const String & | origin | ) |

| Notify this particle system of it's origin. Definition at line 536 of file OgreParticleSystem.h.

virtual void Ogre::ParticleSystem::_notifyParticleResized | ( | void |  | ) | `[virtual]`

| Internal callback used by Particles to notify their parent that they have been resized.

virtual void Ogre::ParticleSystem::_notifyParticleRotated | ( | void |  | ) | `[virtual]`

| Internal callback used by Particles to notify their parent that they have been rotated.

void Ogre::ParticleSystem::_notifyReorganiseEmittedEmitterData | ( | void |  | ) | `[protected]`

This function clears all data structures that are used in combination with emitted emitters and sets the flag to indicate that the emitted emitter pool must be initialised again.

Remarks:
  This function should be called if new emitters are added to a ParticleSystem or deleted from a ParticleSystem. The emitted emitter data structures become out of sync and need to be build up again. The data structures are not reorganised in this function, but by setting a ´flag´, they are rebuild in the regular process flow.

void Ogre::ParticleSystem::_sortParticles | ( | Camera * | cam | ) | `[protected]`

| Sort the particles in the system *.

void Ogre::ParticleSystem::_triggerAffectors | ( | Real | timeElapsed | ) | `[protected]`

| Applies the effects of affectors.

void Ogre::ParticleSystem::_triggerEmitters | ( | Real | timeElapsed | ) | `[protected]`

| Spawn new particles based on free quota and emitter requirements.

void Ogre::ParticleSystem::_update | ( | Real | timeElapsed | ) |

Updates the particles in the system based on time elapsed.

Remarks:
  This is called automatically every frame by OGRE.

Parameters:

  | timeElapsed | The amount of time, in seconds, since the last frame.

void Ogre::ParticleSystem::_updateBounds | ( | void |  | ) |

Internal method for updating the bounds of the particle system.

Remarks:
  This is called automatically for a period of time after the system's creation (10 seconds by default, settable by setBoundsAutoUpdated) to increase (and only increase) the bounds of the system according to the emitted and affected particles. After this period, the system is assumed to achieved its maximum size, and the bounds are no longer computed for efficiency. You can tweak the behaviour by either setting the bounds manually (setBounds, preferred), or changing the time over which the bounds are updated (performance cost). You can also call this method manually if you need to update the bounds on an ad-hoc basis.

virtual void Ogre::ParticleSystem::_updateRenderQueue | ( | RenderQueue * | queue | ) | `[virtual]`

Overridden from MovableObject.

See also:
  MovableObject

Implements Ogre::MovableObject.

void Ogre::ParticleSystem::addActiveEmittedEmittersToFreeList | ( | void |  | ) | `[protected]`

Moves all emitted emitters from the active list to the free list.

Remarks:
  The active emitted emitter list will not be cleared and still keeps references to the emitters!

ParticleAffector* Ogre::ParticleSystem::addAffector | ( | const String & | affectorType | ) |

Adds an affector to this particle system.

Remarks:
  Particles are modified over time in a particle system by affectors - see the ParticleAffector class for more details.

Parameters:

  | affectorType | String identifying the affector type to create. Affector types are defined by registering new factories with the manager - see ParticleAffectorFactory for more details. Affector types can be extended by OGRE, plugin authors or application developers.

ParticleEmitter* Ogre::ParticleSystem::addEmitter | ( | const String & | emitterType | ) |

Adds an emitter to this particle system.

Remarks:
  Particles are created in a particle system by emitters - see the ParticleEmitter class for more details.

Parameters:

  | emitterType | String identifying the emitter type to create. Emitter types are defined by registering new factories with the manager - see ParticleEmitterFactory for more details. Emitter types can be extended by OGRE, plugin authors or application developers.

void Ogre::ParticleSystem::addFreeEmittedEmitters | ( | void |  | ) | `[protected]`

| Add emitters from the pool to the free emitted emitter queue.

virtual void Ogre::MovableObject::addQueryFlags | ( | uint32 | flags | ) | `[virtual, inherited]`

| As setQueryFlags, except the flags passed as parameters are appended to the existing flags on this object. Definition at line 338 of file OgreMovableObject.h.

virtual void Ogre::MovableObject::addVisibilityFlags | ( | uint32 | flags | ) | `[virtual, inherited]`

| As setVisibilityFlags, except the flags passed as parameters are appended to the existing flags on this object. Definition at line 366 of file OgreMovableObject.h.

static void Ogre::StringInterface::cleanupDictionary | ( |  | ) | `[static, inherited]`

| Cleans up the static 'msDictionary' required to reset Ogre, otherwise the containers are left with invalid pointers, which will lead to a crash as soon as one of the ResourceManager implementers (e.g. MaterialManager) initializes.

void Ogre::ParticleSystem::clear | ( |  | ) |

| Empties this set of all particles.

void Ogre::ParticleSystem::configureRenderer | ( | void |  | ) | `[protected]`

| Internal method to configure the renderer.

virtual void Ogre::StringInterface::copyParametersTo | ( | StringInterface * | dest | ) | const`[virtual, inherited]`

Method for copying this object's parameters to another object.

Remarks:
  This method takes the values of all the object's parameters and tries to set the same values on the destination object. This provides a completely type independent way to copy parameters to other objects. Note that because of the String manipulation involved, this should not be regarded as an efficient process and should be saved for times outside of the rendering loop.

  Any unrecognised parameters will be ignored as with setParameter method.

Parameters:

  | dest | Pointer to object to have it's parameters set the same as this object.

virtual AnimableValuePtr Ogre::AnimableObject::createAnimableValue | ( | const String & | valueName | ) | `[virtual, inherited]`

Create a reference-counted AnimableValuePtr for the named value.

Remarks:
  You can use the returned object to animate a value on this object, using AnimationTrack. Subclasses must override this if they wish to support animation of their values.

Reimplemented in Ogre::Light.

Definition at line 285 of file OgreAnimable.h.

References OGRE_EXCEPT.

Particle* Ogre::ParticleSystem::createEmitterParticle | ( | const String & | emitterName | ) |

Manually add an emitter particle to the system.

Remarks:
  The purpose of a particle emitter is to emit particles. Besides visual particles, also other other particle types can be emitted, other emitters for example. The emitted emitters have a double role; they behave as particles and can be influenced by affectors, but they are still emitters and capable to emit other particles (or emitters). It is possible to create a chain of emitters - emitters emitting other emitters, which also emit emitters.

Parameters:

  | emitterName | The name of a particle emitter that must be emitted.

bool Ogre::StringInterface::createParamDictionary | ( | const String & | className | ) | `[protected, inherited]`

Internal method for creating a parameter dictionary for the class, if it does not already exist.

Remarks:
  This method will check to see if a parameter dictionary exist for this class yet, and if not will create one. NB you must supply the name of the class (RTTI is not used or performance).

Parameters:

  | className | the name of the class using the dictionary

Returns:
  true if a new dictionary was created, false if it was already there

Definition at line 176 of file OgreStringInterface.h.

Particle* Ogre::ParticleSystem::createParticle | ( | void |  | ) |

Manually add a particle to the system.

Remarks:
  Instead of using an emitter, you can manually add a particle to the system. You must initialise the returned particle instance immediately with the 'emission' state.

Note:
  There is no corresponding 'destroyParticle' method - if you want to dispose of a particle manually (say, if you've used setSpeedFactor(0) to make particles live forever) you should use getParticle() and modify it's timeToLive to zero, meaning that it will get cleaned up in the next update.

void Ogre::ParticleSystem::createVisualParticles | ( | size_t | poolstart,
|  | size_t | poolend
| ) | `[protected]`

| Internal method for creating ParticleVisualData instances for the pool.

|  | size_t | poolend
| ) | `[protected]`

| Internal method for destroying ParticleVisualData instances for the pool.

virtual void Ogre::ShadowCaster::extrudeBounds | ( | AxisAlignedBox & | box,
|  | const Vector4 & | lightPos,
|  | Real | extrudeDist
| ) | const`[protected, virtual, inherited]`

Utility method for extruding a bounding box.

Parameters:

  | box | Original bounding box, will be updated in-place
  | lightPos | 4D light position in object space, when w=0.0f this represents a directional light
  | extrudeDist | The distance to extrude

static void Ogre::ShadowCaster::extrudeVertices | ( | const HardwareVertexBufferSharedPtr & | vertexBuffer,
|  | size_t | originalVertexCount,
|  | const Vector4 & | lightPos,
|  | Real | extrudeDist
| ) | `[static, inherited]`

Utility method for extruding vertices based on a light.

Remarks:
  Unfortunately, because D3D cannot handle homogenous (4D) position coordinates in the fixed-function pipeline (GL can, but we have to be cross-API), when we extrude in software we cannot extrude to infinity the way we do in the vertex program (by setting w to 0.0f). Therefore we extrude by a fixed distance, which may cause some problems with larger scenes. Luckily better hardware (ie vertex programs) can fix this.

Parameters:

  | vertexBuffer | The vertex buffer containing ONLY xyz position values, which must be originalVertexCount * 2 * 3 floats long.
  | originalVertexCount | The count of the original number of vertices, ie the number in the mesh, not counting the doubling which has already been done (by VertexData::prepareForShadowVolume) to provide the extruded area of the buffer.
  | lightPos | 4D light position in object space, when w=0.0f this represents a directional light
  | extrudeDist | The distance to extrude

void Ogre::ParticleSystem::fastForward | ( | Real | time,
|  | Real | interval = `0.1`
| ) |

Fast-forwards this system by the required number of seconds.

Remarks:
  This method allows you to fast-forward a system so that it effectively looks like it has already been running for the time you specify. This is useful to avoid the 'startup sequence' of a system, when you want the system to be fully populated right from the start.

Parameters:

  | time | The number of seconds to fast-forward by.
  | interval | The sampling interval used to generate particles, apply affectors etc. The lower this is the more realistic the fast-forward, but it takes more iterations to do it.

FreeEmittedEmitterList* Ogre::ParticleSystem::findFreeEmittedEmitter | ( | const String & | name | ) | `[protected]`

Find the list with free emitted emitters.

Parameters:

  | name | The name that identifies the list with free emitted emitters.

virtual void Ogre::ShadowCaster::generateShadowVolume | ( | EdgeData * | edgeData,
|  | const HardwareIndexBufferSharedPtr & | indexBuffer,

|  | ShadowRenderableList & | shadowRenderables,
|  | unsigned long | flags
| ) | `[protected, virtual, inherited]`

Generates the indexes required to render a shadow volume into the index buffer which is passed in, and updates shadow renderables to use it.

Parameters:

  | edgeData | The edge information to use
  | indexBuffer | The buffer into which to write data into; current contents are assumed to be discardable.
  | light | The light, mainly for type info as silhouette calculations should already have been done in updateEdgeListLightFacing
  | shadowRenderables | A list of shadow renderables which has already been constructed but will need populating with details of the index ranges to be used.
  | flags | Additional controller flags, see ShadowRenderableFlags

ParticleAffector* Ogre::ParticleSystem::getAffector | ( | unsigned short | index | ) | const

Retrieves an affector by it's index (zero-based).

Remarks:
  Used to retrieve a pointer to an affector for a particle system to procedurally change affector parameters etc. You should check how many affectors are registered against this system before calling this method with an arbitrary index using getNumAffectors.

Parameters:

  | index | Zero-based index of the affector to retrieve.

virtual const String& Ogre::AnimableObject::getAnimableDictionaryName | ( | void |  | ) | const`[protected, virtual, inherited]`

ParticleEmitter* Ogre::ParticleSystem::getEmitter | ( | unsigned short | index | ) | const

Retrieves an emitter by it's index (zero-based).

Remarks:
  Used to retrieve a pointer to an emitter for a particle system to procedurally change emission parameters etc. You should check how many emitters are registered against this system before calling this method with an arbitrary index using getNumEmitters.

| Returns the number of affectors for this particle system.

unsigned short Ogre::ParticleSystem::getNumEmitters | ( | void |  | ) | const

| Returns the number of emitters for this particle system.

size_t Ogre::ParticleSystem::getNumParticles | ( | void |  | ) | const

Gets the number of individual particles in the system right now.

Remarks:
  The number of particles active in a system at a point in time depends on the number of emitters, their emission rates, the time-to-live (TTL) each particle is given on emission (and whether any affectors modify that TTL) and the maximum number of particles allowed in this system at once (particle quota).

const String& Ogre::ParticleSystem::getOrigin | ( | void |  | ) | const

Get the origin of this particle system, e.g.

a script file name.

Remarks:
  This property will only contain something if the creator of this particle system chose to populate it. Script loaders are advised to populate it.

Returns:
  A reference to a static list of ParameterDef objects.

virtual Node* Ogre::MovableObject::getParentNode | ( | void |  | ) | const`[virtual, inherited]`

Returns the node to which this object is attached.

Remarks:
  A MovableObject may be attached to either a SceneNode or to a TagPoint, the latter case if it's attached to a bone on an animated entity. Both are Node subclasses so this method will return either.

virtual SceneNode* Ogre::MovableObject::getParentSceneNode | ( | void |  | ) | const`[virtual, inherited]`

Returns the scene node to which this object is attached.

Remarks:
  A MovableObject may be attached to either a SceneNode or to a TagPoint, the latter case if it's attached to a bone on an animated entity. This method will return the scene node of the parent entity if the latter is true.

Particle* Ogre::ParticleSystem::getParticle | ( | size_t | index | ) |

Retrieve a particle from the system for manual tweaking.

Remarks:
  Normally you use an affector to alter particles in flight, but for small manually controlled particle systems you might want to use this method.

Remarks:
  See ParticleSystem::setParticleQuota for more info.

void Ogre::ParticleSystem::increaseEmittedEmitterPool | ( | size_t | size | ) | `[protected]`

Resize the internal pool of emitted emitters.

Remarks:
  The pool consists of multiple vectors containing pointers to particle emitters. Increasing the pool with ´size´ implies that the vectors are equally increased. The quota of emitted emitters is defined on a particle system level and not on a particle emitter level. This is to prevent that the number of created emitters becomes too high; the quota is shared amongst the emitted emitters.

void Ogre::ParticleSystem::increasePool | ( | size_t | size | ) | `[protected]`

| Resize the internal pool of particles.

virtual void Ogre::AnimableObject::initialiseAnimableDictionary | ( | StringVector & |  | ) | const`[protected, virtual, inherited]`

| Internal method for initialising dictionary; should be implemented by subclasses wanting to expose animable parameters. Reimplemented in Ogre::Light. Definition at line 252 of file OgreAnimable.h.

void Ogre::ParticleSystem::initialiseEmittedEmitterPool | ( | void |  | ) | `[protected]`

| Determine which emitters in the Particle Systems main emitter become a template for creating an pool of emitters that can be emitted.

void Ogre::ParticleSystem::initialiseEmittedEmitters | ( | void |  | ) | `[protected]`

Create a pool of emitted emitters and assign them to the free emitter list.

Remarks:
  The emitters in the pool are grouped by name. This name is the name of the base emitter in the main list with particle emitters, which forms the template of the created emitted emitters.

void Ogre::ParticleSystem::initParameters | ( | void |  | ) | `[protected]`

| Internal method for initialising string interface.

virtual bool Ogre::MovableObject::isAttached | ( | void |  | ) | const`[virtual, inherited]`

| Returns true if this object is attached to a SceneNode or TagPoint.

virtual bool Ogre::MovableObject::isInScene | ( | void |  | ) | const`[virtual, inherited]`

| Returns true if this object is attached to a SceneNode or TagPoint, and this SceneNode / TagPoint is currently in an active part of the scene graph.

virtual bool Ogre::MovableObject::isVisible | ( | void |  | ) | const`[virtual, inherited]`

Returns whether or not this object is supposed to be visible or not.

Remarks:
  Takes into account both upper rendering distance and visible flag.

Reimplemented in Ogre::InstancedGeometry::BatchInstance, and Ogre::StaticGeometry::Region.

ParticleSystem& Ogre::ParticleSystem::operator= | ( | const ParticleSystem & | rhs | ) |

Assignment operator for copying.

Remarks:
  This operator deep copies all particle emitters and effectors, but not particles. The system's name is also not copied.

virtual const LightList& Ogre::MovableObject::queryLights | ( | void |  | ) | const`[virtual, inherited]`

Gets a list of lights, ordered relative to how close they are to this movable object.

Remarks:
  By default, this method gives the listener a chance to populate light list first, if there is no listener or Listener::objectQueryLights returns NULL, it'll query the light list from parent entity if it is present, or returns SceneNode::findLights if it has parent scene node, otherwise it just returns an empty list.

  The object internally caches the light list, so it will recalculate it only when object is moved, or lights that affect the frustum have been changed (

See also:
  SceneManager::_getLightsDirtyCounter), but if listener exists, it will be called each time, so the listener should implement their own cache mechanism to optimise performance.

  This method can be useful when implementing Renderable::getLights in case the renderable is a part of the movable.

Returns:
  The list of lights use to lighting this object.

void Ogre::ParticleSystem::removeAffector | ( | unsigned short | index | ) |

Removes an affector from the system.

Remarks:
  Drops the affector with the index specified from this system. You should check how many affectors are registered against this system before calling this method with an arbitrary index using getNumAffectors.

Parameters:

  | index | Zero-based index of the affector to retrieve.

void Ogre::ParticleSystem::removeAllAffectors | ( | void |  | ) |

| Removes all the affectors from this system.

void Ogre::ParticleSystem::removeAllEmittedEmitters | ( | void |  | ) | `[protected]`

| Removes all emitted emitters from this system.

void Ogre::ParticleSystem::removeAllEmitters | ( | void |  | ) |

| Removes all the emitters from this system.

void Ogre::ParticleSystem::removeEmitter | ( | unsigned short | index | ) |

Removes an emitter from the system.

Remarks:
  Drops the emitter with the index specified from this system. You should check how many emitters are registered against this system before calling this method with an arbitrary index using getNumEmitters.

Parameters:

  | index | Zero-based index of the emitter to retrieve.

void Ogre::ParticleSystem::removeFromActiveEmittedEmitters | ( | ParticleEmitter * | emitter | ) | `[protected]`

Removes an emitter from the active emitted emitter list.

Remarks:
  The emitter will not be destroyed!

Parameters:

  | emitter | Pointer to a particle emitter.

virtual void Ogre::MovableObject::removeQueryFlags | ( | unsigned long | flags | ) | `[virtual, inherited]`

| As setQueryFlags, except the flags passed as parameters are removed from the existing flags on this object. Definition at line 342 of file OgreMovableObject.h.

virtual void Ogre::MovableObject::removeVisibilityFlags | ( | uint32 | flags | ) | `[virtual, inherited]`

| As setVisibilityFlags, except the flags passed as parameters are removed from the existing flags on this object. Definition at line 370 of file OgreMovableObject.h.

void Ogre::ParticleSystem::setBounds | ( | const AxisAlignedBox & | aabb | ) |

Set the (initial) bounds of the particle system manually.

Remarks:
  If you can, set the bounds of a particle system up-front and call setBoundsAutoUpdated(false); this is the most efficient way to organise it. Otherwise, set an initial bounds and let the bounds increase for a little while (the default is 5 seconds), after which time the AABB is fixed to save time.

Parameters:

  | aabb | Bounds in local space.

void Ogre::ParticleSystem::setBoundsAutoUpdated | ( | bool | autoUpdate,
|  | Real | stopIn = `0.0f`
| ) |

Sets whether the bounds will be automatically updated for the life of the particle system.

Remarks:
  If you have a stationary particle system, it would be a good idea to call this method and set the value to 'false', since the maximum bounds of the particle system will eventually be static. If you do this, you can either set the bounds manually using the setBounds() method, or set the second parameter of this method to a positive number of seconds, so that the bounds are calculated for a few seconds and then frozen.

Parameters:

  | autoUpdate | If true (the default), the particle system will update it's bounds every frame. If false, the bounds update will cease after the 'stopIn' number of seconds have passed.
  | stopIn | Only applicable if the first parameter is true, this is the number of seconds after which the automatic update will cease.

void Ogre::MovableObject::setCastShadows | ( | bool | enabled | ) | `[inherited]`

Sets whether or not this object will cast shadows.

Remarks:
  This setting simply allows you to turn on/off shadows for a given object. An object will not cast shadows unless the scene supports it in any case (see SceneManager::setShadowTechnique), and also the material which is in use must also have shadow casting enabled. By default all entities cast shadows. If, however, for some reason you wish to disable this for a single object then you can do so using this method.

Note:
  This method normally refers to objects which block the light, but since Light is also a subclass of MovableObject, in that context it means whether the light causes shadows itself.

Definition at line 440 of file OgreMovableObject.h.

virtual void Ogre::ParticleSystem::setCullIndividually | ( | bool | cullIndividual | ) | `[virtual]`

Sets whether culling tests particles in this individually as well as in a group.

Remarks:
  Particle sets are always culled as a whole group, based on a bounding box which encloses all particles in the set. For fairly localised sets, this is enough. However, you can optionally tell the set to also cull individual particles in the set, i.e. to test each individual particle before rendering. The default is not to do this.

  This is useful when you have a large, fairly distributed set of particles, like maybe trees on a landscape. You probably still want to group them into more than one set (maybe one set per section of landscape), which will be culled coarsely, but you also want to cull the particles individually because they are spread out. Whilst you could have lots of single-tree sets which are culled separately, this would be inefficient to render because each tree would be issued as it's own rendering operation.

  By calling this method with a parameter of true, you can have large particle sets which are spaced out and so get the benefit of batch rendering and coarse culling, but also have fine-grained culling so unnecessary rendering is avoided.

Parameters:

  | cullIndividual | If true, each particle is tested before being sent to the pipeline as well as the whole set having to pass the coarse group bounding test.

virtual void Ogre::ParticleSystem::setDefaultDimensions | ( | Real | width,
|  | Real | height
| ) | `[virtual]`

Sets the default dimensions of the particles in this set.

Remarks:
  All particles in a set are created with these default dimensions. The set will render most efficiently if all the particles in the set are the default size. It is possible to alter the size of individual particles at the expense of extra calculation. See the Particle class for more info.

Parameters:

  | width | The new default width for the particles in this set.
  | height | The new default height for the particles in this set.

virtual void Ogre::ParticleSystem::setDefaultHeight | ( | Real | height | ) | `[virtual]`

| See setDefaultDimensions - this sets 1 component individually.

static void Ogre::ParticleSystem::setDefaultIterationInterval | ( | Real | iterationInterval | ) | `[static]`

| Set the default iteration interval for all ParticleSystem instances. Definition at line 437 of file OgreParticleSystem.h.

static void Ogre::ParticleSystem::setDefaultNonVisibleUpdateTimeout | ( | Real | timeout | ) | `[static]`

| Set the default nonvisible timeout for all ParticleSystem instances. Definition at line 465 of file OgreParticleSystem.h.

static void Ogre::MovableObject::setDefaultQueryFlags | ( | uint32 | flags | ) | `[static, inherited]`

| Set the default query flags for all future MovableObject instances. Definition at line 349 of file OgreMovableObject.h.

static void Ogre::MovableObject::setDefaultVisibilityFlags | ( | uint32 | flags | ) | `[static, inherited]`

| Set the default visibility flags for all future MovableObject instances. Definition at line 377 of file OgreMovableObject.h.

virtual void Ogre::ParticleSystem::setDefaultWidth | ( | Real | width | ) | `[virtual]`

| See setDefaultDimensions - this sets 1 component individually.

void Ogre::ParticleSystem::setEmittedEmitterQuota | ( | size_t | quota | ) |

Sets the maximum number of emitted emitters this system is allowed to have active at once.

Remarks:
  Particle systems can have - besides a particle quota - also an emitted emitter quota.

Parameters:

  | quota | The maximum number of emitted emitters this system is allowed to have.

void Ogre::ParticleSystem::setIterationInterval | ( | Real | iterationInterval | ) |

Sets a 'iteration interval' on this particle system.

Remarks:
  The default Particle system update interval, based on elapsed frame time, will cause different behavior between low frame-rate and high frame-rate. By using this option, you can make the particle system update at a fixed interval, keeping the behavior the same no matter what frame-rate is.

  When iteration interval is set to zero, it means the update occurs based on an elapsed frame time, otherwise each iteration will take place at the given interval, repeating until it has used up all the elapsed frame time.

Parameters:

  | iterationInterval | The iteration interval, default to zero.

void Ogre::ParticleSystem::setKeepParticlesInLocalSpace | ( | bool | keepLocal | ) |

Sets whether particles (and any affector effects) remain relative to the node the particle system is attached to.

Remarks:
  By defalt particles are in world space once emitted, so they are not affected by movement in the parent node of the particle system. This makes the most sense when dealing with completely independent particles, but if you want to constrain them to follow local motion too, you can set this to true.

virtual void Ogre::MovableObject::setListener | ( | Listener * | listener | ) | `[virtual, inherited]`

Sets a listener for this object.

Remarks:
  Note for size and performance reasons only one listener per object is allowed.

Definition at line 388 of file OgreMovableObject.h.

virtual void Ogre::ParticleSystem::setMaterialName | ( | const String & | name | ) | `[virtual]`

Sets the name of the material to be used for this billboard set.

Parameters:

  | name | The new name of the material to use for this set.

void Ogre::ParticleSystem::setNonVisibleUpdateTimeout | ( | Real | timeout | ) |

Sets when the particle system should stop updating after it hasn't been visible for a while.

Remarks:
  By default, visible particle systems update all the time, even when not in view. This means that they are guaranteed to be consistent when they do enter view. However, this comes at a cost, updating particle systems can be expensive, especially if they are perpetual.

  This option lets you set a 'timeout' on the particle system, so that if it isn't visible for this amount of time, it will stop updating until it is next visible.

Parameters:

  | timeout | The time after which the particle system will be disabled if it is no longer visible. 0 to disable the timeout and always update.

virtual bool Ogre::StringInterface::setParameter | ( | const String & | name,
|  | const String & | value
| ) | `[virtual, inherited]`

Generic parameter setting method.

Remarks:
  Call this method with the name of a parameter and a string version of the value to set. The implementor will convert the string to a native type internally. If in doubt, check the parameter definition in the list returned from StringInterface::getParameters.

Parameters:

  | name | The name of the parameter to set
  | value | String value. Must be in the right format for the type specified in the parameter definition. See the StringConverter class for more information.

Returns:
  true if set was successful, false otherwise (NB no exceptions thrown - tolerant method)

virtual void Ogre::StringInterface::setParameterList | ( | const NameValuePairList & | paramList | ) | `[virtual, inherited]`

Generic multiple parameter setting method.

Remarks:
  Call this method with a list of name / value pairs to set. The implementor will convert the string to a native type internally. If in doubt, check the parameter definition in the list returned from StringInterface::getParameters.

Parameters:

  | paramList | Name/value pair list

void Ogre::ParticleSystem::setParticleQuota | ( | size_t | quota | ) |

Sets the maximum number of particles this system is allowed to have active at once.

Remarks:
  Particle systems all have a particle quota, i.e. a maximum number of particles they are allowed to have active at a time. This allows the application to set a keep particle systems under control should they be affected by complex parameters which alter their emission rates etc. If a particle system reaches it's particle quota, none of the emitters will be able to emit any more particles. As existing particles die, the spare capacity will be allocated equally across all emitters to be as consistent to the origina particle system style as possible.

Parameters:

  | quota | The maximum number of particles this system is allowed to have.

virtual void Ogre::MovableObject::setQueryFlags | ( | uint32 | flags | ) | `[virtual, inherited]`

Sets the query flags for this object.

Remarks:
  When performing a scene query, this object will be included or excluded according to flags on the object and flags on the query. This is a bitwise value, so only when a bit on these flags is set, will it be included in a query asking for that flag. The meaning of the bits is application-specific.

Definition at line 334 of file OgreMovableObject.h.

void Ogre::ParticleSystem::setRenderer | ( | const String & | typeName | ) |

Sets the ParticleRenderer to be used to render this particle system.

Remarks:
  The main ParticleSystem just manages the creation and movement of particles; they are rendered using functions in ParticleRenderer and the ParticleVisual instances they create.

Parameters:

  | typeName | String identifying the type of renderer to use; a new instance of this type will be created; a factory must have been registered with ParticleSystemManager.

virtual void Ogre::MovableObject::setRenderingDistance | ( | Real | dist | ) | `[virtual, inherited]`

Sets the distance at which the object is no longer rendered.

Parameters:

  | dist | Distance beyond which the object will not be rendered (the default is 0, which means objects are always rendered).

Definition at line 272 of file OgreMovableObject.h.

void Ogre::ParticleSystem::setRenderQueueGroup | ( | uint8 | queueID | ) | `[virtual]`

Remarks:
  Render queues are grouped to allow you to more tightly control the ordering of rendered objects. If you do not call this method, all Entity objects default to the default queue (RenderQueue::getDefaultQueueGroup), which is fine for most objects. You may want to alter this if you want this entity to always appear in front of other objects, e.g. for a 3D menu system or such.

  See RenderQueue for more details.

Parameters:

  | queueID | Enumerated value of the queue group to use.

Reimplemented from Ogre::MovableObject.

void Ogre::ParticleSystem::setSortingEnabled | ( | bool | enabled | ) |

Set whether or not particles are sorted according to the camera.

Remarks:
  Enabling sorting alters the order particles are sent to the renderer. When enabled, particles are sent to the renderer in order of furthest distance from the camera.

Definition at line 547 of file OgreParticleSystem.h.

void Ogre::ParticleSystem::setSpeedFactor | ( | Real | speedFactor | ) |

Sets a 'speed factor' on this particle system, which means it scales the elapsed real time which has passed by this factor before passing it to the emitters, affectors, and the particle life calculation.

Remarks:
  An interesting side effect - if you want to create a completely manual particle system where you control the emission and life of particles yourself, you can set the speed factor to 0.0f, thus disabling normal particle emission, alteration, and death.

Definition at line 408 of file OgreParticleSystem.h.

virtual void Ogre::MovableObject::setUserAny | ( | const Any & | anything | ) | `[virtual, inherited]`

Sets any kind of user value on this object.

Remarks:
  This method allows you to associate any user value you like with this MovableObject. This can be a pointer back to one of your own classes for instance.

Note:
  This value is shared with setUserObject so don't use both!

Definition at line 302 of file OgreMovableObject.h.

virtual void Ogre::MovableObject::setUserObject | ( | UserDefinedObject * | obj | ) | `[virtual, inherited]`

Call this to associate your own custom user object instance with this MovableObject.

Remarks:
  By simply making your game / application object a subclass of UserDefinedObject, you can establish a link between an OGRE instance of MovableObject and your own application classes. Call this method to establish the link.

Definition at line 286 of file OgreMovableObject.h.

virtual void Ogre::MovableObject::setVisibilityFlags | ( | uint32 | flags | ) | `[virtual, inherited]`

Sets the visiblity flags for this object.

Remarks:
  As well as a simple true/false value for visibility (as seen in setVisible), you can also set visiblity flags which when 'and'ed with the SceneManager's visibility mask can also make an object invisible.

Definition at line 362 of file OgreMovableObject.h.

virtual void Ogre::MovableObject::setVisible | ( | bool | visible | ) | `[virtual, inherited]`

Tells this object whether to be visible or not, if it has a renderable component.

Note:
  An alternative approach of making an object invisible is to detach it from it's SceneNode, or to remove the SceneNode entirely. Detaching a node means that structurally the scene graph changes. Once this change has taken place, the objects / nodes that have been removed have less overhead to the visbility detection pass than simply making the object invisible, so if you do this and leave the objects out of the tree for a long time, it's faster. However, the act of detaching / reattaching nodes is in itself more expensive than setting an object visibility flag, since in the latter case structural changes are not made. Therefore, small or frequent visbility changes are best done using this method; large or more longer term changes are best done by detaching.

Reimplemented in Ogre::Light.

virtual void Ogre::ShadowCaster::updateEdgeListLightFacing | ( | EdgeData * | edgeData,
|  | const Vector4 & | lightPos
| ) | `[protected, virtual, inherited]`

Tells the caster to perform the tasks necessary to update the edge data's light listing.

Can be overridden if the subclass needs to do additional things.

Parameters:

  | edgeData | The edge information to update
  | lightPos | 4D vector representing the light, a directional light has w=0.0
