详细描述

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
        }
    ]
}
					

特性文档编制

TriggerMode : enumeration

Defines the mode of the bursting.

常量	描述
DynamicBurst3D.TriggerTime	The particles are emitted when the burst time is due.
DynamicBurst3D.TriggerStart	The particles are emitted when the followed particle is emitted.

注意： This property is restricted to only work with trail emitters.

注意： In this mode, time and duration properties don't have an effect.

常量	描述
DynamicBurst3D.TriggerEnd	The particles are emitted when the followed particle lifeSpan ends.

注意： This property is restricted to only work with trail emitters.

注意： 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
}
					

默认值为 0 .

enabled : bool

If enabled is set to false , this burst will not emit any particles.

默认值为 true .

triggerMode : ShapeType

This property defines the emitting mode.

默认值为 TriggerMode.TriggerTime .
