Detailed Description
This element emits logical particles into the ParticleSystem, with the starting positions based on those of other logical particles.
Property Documentation
emitHeight : real |
The height in pixels the emitShape is scaled to. If set to TrailEmitter.ParticleSize, the height will be the current size of the particle being followed.
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 |
The width in pixels the emitShape is scaled to. If set to TrailEmitter.ParticleSize, the width will be the current size of the particle being followed.
Default is 0.
follow : string |
The type of logical particle which this is emitting from.
velocityFromMovement : real |
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.
Signal Documentation
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.
If you use this signal handler, emitParticles will not be emitted.
Note: The corresponding handler is onEmitFollowParticles.
