Member Function Documentation

virtual csPtr<iParticleEmitter> iParticleEmitter::Clone

(

)

const [pure virtual]

Clone this emitter.

virtual void iParticleEmitter::EmitParticles	(	iParticleSystemBase *	system,
		const csParticleBuffer &	particleBuffer,
		float	dt,
		float	totalTime,
		const csReversibleTransform *const	emitterToParticle = 0
	)			[pure virtual]

Spawn new particles.

virtual float iParticleEmitter::GetDuration

(

)

const [pure virtual]

Get duration (in seconds) for this emitter.

virtual float iParticleEmitter::GetEmissionRate

(

)

const [pure virtual]

Get emission rate in particles per second.

virtual bool iParticleEmitter::GetEnabled

(

)

const [pure virtual]

Get emitters enabled state.

virtual void iParticleEmitter::GetInitialMass	(	float &	min,
		float &	max
	)			const [pure virtual]

Get initial mass for new particles.

virtual void iParticleEmitter::GetInitialTTL	(	float &	min,
		float &	max
	)			const [pure virtual]

Get initial time-to-live span.

virtual float iParticleEmitter::GetStartTime

(

)

const [pure virtual]

Get the start time (in seconds).

virtual size_t iParticleEmitter::ParticlesToEmit	(	iParticleSystemBase *	system,
		float	dt,
		float	totalTime
	)			[pure virtual]

Get number of particles this emitter wants to emit.

virtual void iParticleEmitter::SetDuration

(

float

time

)

[pure virtual]

Set duration (in seconds) for this emitter.

By default emitters will emit particles infinitely, but by setting this you can make them stop a given number of seconds after they initiated emission. A negative duration is the same as infinite duration.

virtual void iParticleEmitter::SetEmissionRate

(

float

particlesPerSecond

)

[pure virtual]

Set emission rate in particles per second.

virtual void iParticleEmitter::SetEnabled

(

bool

enabled

)

[pure virtual]

Set emitters enabled state.

The emitter will only emit particles if enabled.

virtual void iParticleEmitter::SetInitialMass	(	float	min,
		float	max
	)			[pure virtual]

Set initial mass for new particles.

The emitter will assign a mass in the range specified.

virtual void iParticleEmitter::SetInitialTTL	(	float	min,
		float	max
	)			[pure virtual]

Set initial time-to-live span.

The emitter will assign a time-to-live in the range specified.

virtual void iParticleEmitter::SetStartTime

(

float

time

)

[pure virtual]

Set the start time (in seconds) for this emitter.

By default emitters will start emitting particles as soon as the particle system is activated (comes into view), but with this setting this can be delayed.
