QT_BEGIN_NAMESPACE QQuick3DParticleEmitter::QQuick3DParticleEmitter ( QQuick3DNode * parent = nullptr )

\qmltype ParticleEmitter3D \inherits Node \inqmlmodule QtQuick3D.Particles3D

Emitter for logical particles.

Since: 6.2

This element emits logical particles into the \l ParticleSystem3D, with the given starting attributes.

At least one emitter is required to have particles in the \l ParticleSystem3D. There are a few different ways to control the emitting amount: \list

Set the \l emitRate which controls how many particles per second get emitted continuously.
Add \l EmitBurst3D elements into emitBursts property to emit bursts declaratively.
Call any of the \l burst() methods to emit bursts immediately. \endlist

Holds the depth bias of the emitter. Depth bias is added to the object distance from camera when sorting objects. This can be used to force rendering order between objects close to each other, that might otherwise be rendered in different order in different frames. Negative values cause the sorting value to move closer to the camera while positive values move it further from the camera.

\qmlproperty List<EmitBurst3D> ParticleEmitter3D::emitBursts

This property takes a list of \l EmitBurst3D elements, to declaratively define bursts. If the burst starting time, amount, and duration are known beforehand, it is better to use this property than e.g. calling \l burst() with a \l Timer.

For example, to emit 100 particles at the beginning, and 50 particles at 2 seconds:

\qml ParticleEmitter3D { emitBursts: [ EmitBurst3D { time: 0 amount: 100 }, EmitBurst3D { time: 2000 amount: 50 } ] } \endqml
