## Detailed Description

A particle system scene node for creating snow, fire, exlosions, smoke...

A scene node controlling a particle System. The behavior of the particles can be controlled by setting the right particle emitters and affectors. You can for example easily create a campfire by doing this:

            scene::IParticleSystemSceneNode* p = scenemgr->addParticleSystemSceneNode();
            p->setParticleSize(core::dimension2d<f32>(20.0f, 10.0f));
            scene::IParticleEmitter* em = p->createBoxEmitter(
                    core::aabbox3d<f32>(-5,0,-5,5,1,5),
                    core::vector3df(0.0f,0.03f,0.0f),
                    40,80, video::SColor(0,255,255,255),video::SColor(0,255,255,255), 1100,2000);
            p->setEmitter(em);
            em->drop();
            scene::IParticleAffector* paf = p->createFadeOutParticleAffector();
            p->addAffector(paf);
            paf->drop();

## Member Function Documentation

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.

|  | 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_VERTEX_ALPHA 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 milli seconds 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 informations.

| ) |  |  | `[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 catched by the gravity then. This affector is ideal for creating things like fountains.

Parameters:

  | gravity,: | Direction and force of gravity.
  | timeForceLost,: | Time in milli seconds 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.

virtual void irr::scene::IParticleSystemSceneNode::setEmitter | ( | IParticleEmitter * | emitter | ) | `[pure virtual]`

Sets the particle emitter, which creates the particles.

A particle emitter can be created using one of the createEmitter methods. For example to create and use a simple PointEmitter, call IParticleEmitter* p = createPointEmitter(); setEmitter(p); p->drop();

Parameters:

  | emitter,: | Sets the particle emitter. You can set this to 0 for removing the current emitter and stopping the particle system emitting new particles.

Sets if the particles should be global.

If they are, the particles are affected by the movement of the particle system scene node too, otherwise they completely ignore it. Default is true.
