Inherits:: EmitBurst3D
Detailed Description▲
This element defines particle bursts in the ParticleEmitter3D. These bursts are dynamic, meaning that they are evaluated while the particlesystem runs. Use these instead of EmitBurst3D for example when the emitter moves, so that emitting happens at the correct position.
For example, to emit 100 particles at 1 second time and 200 particles at 2 second:
ParticleEmitter3D {
...
emitBursts: [
DynamicBurst3D {
time: 1000
amount: 100
},
DynamicBurst3D {
time: 2000
amount: 200
}
]
}Property Documentation▲
TriggerMode : enumeration▲
Defines the mode of the bursting.
|
Constant |
Description |
|---|---|
|
DynamicBurst3D.TriggerTime |
The particles are emitted when the burst time is due. |
|
DynamicBurst3D.TriggerStart |
The particles are emitted when the followed particle is emitted. |
This property is restricted to only work with trail emitters.
In this mode, time and duration properties don't have an effect.
|
Constant |
Description |
|---|---|
|
DynamicBurst3D.TriggerEnd |
The particles are emitted when the followed particle lifeSpan ends. |
This property is restricted to only work with trail emitters.
In this mode, time and duration properties don't have an effect.
amountVariation : int▲
This property defines the random variation in particle emit amount.
For example, to have a random range between 0 and 10
DynamicBurst3D {
time: 1000
amount: 5
amountVariation: 5
}The default value is 0.
enabled : bool▲
If enabled is set to false, this burst will not emit any particles.
The default value is true.
triggerMode : ShapeType▲
This property defines the emitting mode.
The default value is TriggerMode.TriggerTime.
