◆ addAffector()

virtual void irr::scene::IParticleSystemSceneNode::addAffector ( IParticleAffector * affector )

pure virtual

Adds new particle effector to the particle system.

A particle affector modifies the particles. For example, the FadeOut affector lets all particles fade out after some time. It is created and used in this way:

IParticleAffector* p = createFadeOutParticleAffector();
addAffector(p);
p->drop();

Please note that an affector is not necessary for the particle system to work.

Parameters

affector New affector.

◆ clearParticles()

virtual void irr::scene::IParticleSystemSceneNode::clearParticles ( )

pure virtual

Remove all currently visible particles.

	)

pure virtual

Creates a particle emitter for an animated mesh scene node.

Parameters

node	Pointer to the animated mesh scene node to emit particles from
useNormalDirection	If true, the direction of each particle created will be the normal of the vertex that it's emitting from. The normal is divided by the normalDirectionModifier parameter, which defaults to 100.0f.
direction	Direction and speed of particle emission.
normalDirectionModifier	If the emitter is using the normal direction then the normal of the vertex that is being emitted from is divided by this number.
mbNumber	This allows you to specify a specific meshBuffer for the IMesh* to emit particles from. The default value is -1, which means a random meshBuffer picked from all of the meshes meshBuffers will be selected to pick a random vertex from. If the value is 0 or greater, it will only pick random vertices from the meshBuffer specified by this value.
everyMeshVertex	If true, the emitter will emit between min/max particles every second, for every vertex in the mesh, if false, it will emit between min/max particles from random vertices in the mesh.
minParticlesPerSecond	Minimal amount of particles emitted per second.
maxParticlesPerSecond	Maximal amount of particles emitted per second.
minStartColor	Minimal initial start color of a particle. The real color of every particle is calculated as random interpolation between minStartColor and maxStartColor.
maxStartColor	Maximal initial start color of a particle. The real color of every particle is calculated as random interpolation between minStartColor and maxStartColor.
lifeTimeMin	Minimal lifetime of a particle, in milliseconds.
lifeTimeMax	Maximal lifetime of a particle, in milliseconds.
maxAngleDegrees	Maximal angle in degrees, the emitting direction of the particle will differ from the original direction.
minStartSize	Minimal initial start size of a particle. The real size of every particle is calculated as random interpolation between minStartSize and maxStartSize.
maxStartSize	Maximal initial start size of a particle. The real size of every particle is calculated as random interpolation between minStartSize and maxStartSize.

Returns: Pointer to the created particle emitter. To set this emitter as new emitter of this particle system, just call setEmitter(). Note that you'll have to drop() the returned pointer, after you don't need it any more, see IReferenceCounted::drop() for more information.

		bool	attract = `true`,
		bool	affectX = `true`,
		bool	affectY = `true`,
		bool	affectZ = `true`
	)

pure virtual

Creates a point attraction affector.

This affector modifies the positions of the particles and attracts them to a specified point at a specified speed per second.

Parameters

point	Point to attract particles to.
speed	Speed in units per second, to attract to the specified point.
attract	Whether the particles attract or detract from this point.
affectX	Whether or not this will affect the X position of the particle.
affectY	Whether or not this will affect the Y position of the particle.
affectZ	Whether or not this will affect the Z position of the particle.

Returns: Pointer to the created particle affector. To add this affector as new affector of this particle system, just call addAffector(). Note that you'll have to drop() the returned pointer, after you don't need it any more, see IReferenceCounted::drop() for more information.

◆ createFadeOutParticleAffector()

virtual IParticleFadeOutAffector* irr::scene::IParticleSystemSceneNode::createFadeOutParticleAffector	(	const video::SColor &	targetColor = `video::SColor(0, 0, 0, 0)`,
		u32	timeNeededToFadeOut = `1000`
	)

pure virtual

Creates a fade out particle affector.

This affector modifies the color of every particle and and reaches the final color when the particle dies. This affector looks really good, if the EMT_TRANSPARENT_ADD_COLOR material is used and the targetColor is video::SColor(0,0,0,0): Particles are fading out into void with this setting.

Parameters

targetColor	Color whereto the color of the particle is changed.
timeNeededToFadeOut	How much time in milliseconds should the affector need to change the color to the targetColor.

Returns: Pointer to the created particle affector. To add this affector as new affector of this particle system, just call addAffector(). Note that you'll have to drop() the returned pointer, after you don't need it any more, see IReferenceCounted::drop() for more information.

◆ createGravityAffector()

		u32	timeForceLost = `1000`
	)

pure virtual

Creates a gravity affector.

This affector modifies the direction of the particle. It assumes that the particle is fired out of the emitter with huge force, but is loosing this after some time and is caught by the gravity then. This affector is ideal for creating things like fountains.

Parameters

gravity	Direction and force of gravity.
timeForceLost	Time in milliseconds when the force of the emitter is totally lost and the particle does not move any more. This is the time where gravity fully affects the particle.

Returns: Pointer to the created particle affector. To add this affector as new affector of this particle system, just call addAffector(). Note that you'll have to drop() the returned pointer, after you don't need it any more, see IReferenceCounted::drop() for more information.

pure virtual

Creates a mesh particle emitter.

Parameters

mesh	Pointer to mesh to emit particles from
useNormalDirection	If true, the direction of each particle created will be the normal of the vertex that it's emitting from. The normal is divided by the normalDirectionModifier parameter, which defaults to 100.0f.
direction	Direction and speed of particle emission.
normalDirectionModifier	If the emitter is using the normal direction then the normal of the vertex that is being emitted from is divided by this number.
mbNumber	This allows you to specify a specific meshBuffer for the IMesh* to emit particles from.
