au3Irr2 Function Reference
_IrrAddFadeOutParticleAffectorAdds a fade out affector to a particle system gradually fading particles out so they are invisible when they are deleted.
#Include <au3Irrlicht2.au3>
_IrrAddFadeOutParticleAffector($h_ParticleSystem, $i_FadeFactor, $i_Red, $i_Green, $i_Blue)
Parameters
| $h_ParticleSystem | Handle of the particle system the created affector is attached to. |
| $i_FadeFactor | Milliseconds the fade out effect will take place. |
| $i_Red, $i_Green, $i_Blue | Values of the colour the particles are faded to (0-255) |
Return Value
success: Handle of the created affector.failure: false
Remarks
The fade out affector fades the particles out as they come to the end of their lifespan and stops them 'popping' out of existance. This creates a convincing effect for fire and smoke in particular.
