Methods

• public constructor Create  ( AOwner :  TComponent ) ;

• protected procedure SetEmitter  ( const  AValue :  TComponent ) ;
• protected procedure DoOnInterpolate  ( const  ADeltaTime :  Single; const  AParticle :  PGorillaParticle ) ;  abstract virtual;

  The DoOnInterpolate() method will be called on every emitting step for every particle. The DeltaTime defines the time between the last step and now. The particle parameter is a pointer to a single particle.

• protected procedure DoOnEmitParticle  ( const  AParticle :  PGorillaParticle ) ;  virtual;

  The DoOnEmitParticle method is used inside the influencer to react on particle emitation. Overwrite this method to implement individual behaviour.

• protected procedure DoOnDestroyParticle  ( const  AParticle :  PGorillaParticle ) ;  virtual;

  The DoOnDestroyParticle method is used inside the influencer to react on particle destruction. Overwrite this method to implement individual behaviour.

• protected procedure Loaded  ( ) ;  override;
• public procedure Interpolate  ( const  ADeltaTime :  Single; const  AParticle :  PGorillaParticle ) ;

  The Interpolate() method will be called on every emitting step for every particle. The DeltaTime defines the time between the last step and now. The particle parameter is a pointer to a single particle. Overwrite the abstract DoOnInterpolate() method in your extended influencer class.

• public procedure EmitParticleCallback  ( const  AParticle :  PGorillaParticle ) ;

  The EmitParticleCallback() method is called from the emitter instance, when a particle is emitted. The influencer can react on this behaviour individually. To execute specific actions overwrite the protected abstract method DoOnEmitParticle() method.

• public procedure DestroyParticleCallback  ( const  AParticle :  PGorillaParticle ) ;

  The DestroyParticleCallback() method is called from the emitter instance, when a particle is destroyed. The influencer can react on this behaviour individually. To execute specific actions overwrite the protected abstract method DoOnDestroyParticle() method.

Properties

  Defines if the influencer is enabled or disabled. If the influencer is not enabled, it will not affect any particles.

• published Emitter : TComponent
