Dynamic emitter bursts. 更多...
import 语句: | import QtQuick3D.Particles3D |
Since: | Qt 6.3 |
继承: | EmitBurst3D |
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 } ] }
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
.
