Declarative emitter bursts. 更多...

This element defines particle bursts in the ParticleEmitter3D .
For example, to emit 100 particles at the beginning, and 50 particles at 2 seconds, so that both bursts take 200 milliseconds:
ParticleEmitter3D { ... emitBursts: [ EmitBurst3D { time: 0 amount: 100 duration: 200 }, EmitBurst3D { time: 2000 amount: 50 duration: 200 } ] }
amount : int |
This property defines the amount of particles emitted during the burst.
默认值为
0
.
duration : int |
This property defines the duration of the burst. The default value is 0, meaning all particles will burst at the beginning of
time
. If the duration is set, particles emitting is distributed between
time
and
time
+
duration
.
For example, to have emit rate of 400 between 1000 and 1200 milliseconds:
EmitBurst3D { time: 1000 amount: 80 duration: 1200 }
默认值为
0
.
time : int |
This property defines the time in milliseconds when emitting the burst starts.
默认值为
0
