Detailed Description

A Particle which destroys itself after a decay time has elapsed.

Constructor & Destructor Documentation

WaterParticle::WaterParticle	(	ParticleLayer *	layer,
		const QPointF &	position,
		const QPointF &	velocity,
		const QColor &	color,
		float	decayTime
	)

Constructs a WaterParticle in the given ParticleLayer with the specified position, velocity, color, and time-to-live.

Parameters

layer	ParticleLayer to spawn particle in
position	Position in world coordinates to spawn the particle at
velocity	Initial velocity of the particle
color	Color of the particle
decayTime	Decay time of the particle

WaterParticle::WaterParticle	(	ParticleLayer *	layer,
		int	index,
		float	decayTime
	)

Constructs a WaterParticle to represent an already existing particle in the particle system.

This method uses Particle::mapToExistingParticle() to attach to an existing particle.

Parameters

layer	ParticleLayer the existing particle is in
index	Index of the particle to attach to
decayTime	Decay time of the particle

Member Function Documentation

void WaterParticle::beginDecaying

(

)

Start the decay of this WaterParticle.

Once the decay time interval of game time has elapsed, the WaterParticle will delete itself in update().

void WaterParticle::resetDecayTime

(

)

Reset the decay time of this WaterParticle.

void WaterParticle::update

(

)

Process the decay timer, deleting this WaterParticle if the decay time has elapsed.
