- emitHeight : real
- emitRatePerParticle : real
- emitShape : Shape
- emitWidth : real
- follow : string
- velocityFromMovement : qreal
- void emitFollowParticles(Array particles, Particle followed)
This element emits logical particles into the ParticleSystem, with the starting positions based on those of other logical particles.
emitHeight : real
Default is 0.
emitRatePerParticle : real
emitShape : Shape
As the area of a TrailEmitter is the area it follows, a separate shape can be provided to be the shape it emits out of. This shape has width and height specified by emitWidth and emitHeight, and is centered on the followed particle's position.
The default shape is a filled Rectangle.
emitWidth : real
Default is 0.
follow : string
The type of logical particle which this is emitting from.
velocityFromMovement : qreal
If this value is non-zero, then any movement of the emitter will provide additional starting velocity to the particles based on the movement. The additional vector will be the same angle as the emitter's movement, with a magnitude that is the magnitude of the emitters movement multiplied by velocityFromMovement.
Default value is 0.
void emitFollowParticles(Array particles, Particle followed)
This signal is emitted when particles are emitted from the followed particle. particles contains an array of particle objects which can be directly manipulated.
The corresponding handler is
onEmitFollowParticles. If you use this signal handler, emitParticles will not be emitted.
