Constructor & Destructor Documentation

◆ QQuick3DParticleEmitBurst()

QT_BEGIN_NAMESPACE QQuick3DParticleEmitBurst::QQuick3DParticleEmitBurst ( QObject * parent = nullptr )

\qmltype EmitBurst3D \inherits QtObject \inqmlmodule QtQuick3D.Particles3D

Declarative emitter bursts.

Since: 6.2

This element defines particle bursts in the \l ParticleEmitter3D. These bursts are static, meaning that they are evaluated when the particlesystem starts. This allows better performance than \l DynamicBurst3D and bursting outside of the particlesystem time (so e.g. burst at 1000ms while system time starts from 2000ms).

Note: EmitBurst3D uses emitter properties (position, rotation etc.) at the particlesystem start. For dynamic emitters, use \l DynamicBurst3D instead.

For example, to emit 100 particles at the beginning, and 50 particles at 2 seconds, so that both bursts take 200 milliseconds:

\qml ParticleEmitter3D { ... emitBursts: [ EmitBurst3D { time: 0 amount: 100 duration: 200 }, EmitBurst3D { time: 2000 amount: 50 duration: 200 } ] } \endqml

Member Function Documentation

◆ amount()

int QQuick3DParticleEmitBurst::amount ( ) const

\qmlproperty int EmitBurst3D::amount

This property defines the amount of particles emitted during the burst.

The default value is 0.

inlineoverrideprotectedvirtual

Invoked after class creation, but before any properties have been set.

Implements QQmlParserStatus.

Definition at line 60 of file qquick3dparticleemitburst_p.h.

◆ componentComplete()

void QQuick3DParticleEmitBurst::componentComplete ( )

overrideprotectedvirtual

Invoked after the root component that caused this instantiation has completed construction.

At this point all static values and binding values have been assigned to the class.

Implements QQmlParserStatus.

Definition at line 139 of file qquick3dparticleemitburst.cpp.

References QObject::parent(), qWarning, and QQuick3DParticleEmitter::registerEmitBurst().

Here is the call graph for this function:

◆ duration()

int QQuick3DParticleEmitBurst::duration ( ) const

\qmlproperty int EmitBurst3D::duration

This property defines the duration of the burst. The default value is 0, meaning all particles will burst at the beginning of \l 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: \qml EmitBurst3D { time: 1000 amount: 80 duration: 1200 } \endqml

The default value is 0.
