◆ isPaused()

bool QQuick3DParticleSystem::isPaused ( ) const

\qmlproperty bool ParticleSystem3D::paused

This property defines if system is currently paused. If paused is set to true, the particle system will not advance the simulation. When paused is set to false again, the simulation will resume from the same point where it was paused.

The default value is false.

Definition at line 127 of file qquick3dparticlesystem.cpp.

◆ isRunning()

bool QQuick3DParticleSystem::isRunning ( ) const

\qmlproperty bool ParticleSystem3D::running

This property defines if system is currently running. If running is set to false, the particle system will stop the simulation. All particles will be destroyed when the system is set to running again.

Running should be set to false when manually modifying/animating the \l {ParticleSystem3D::time}{time} property.

This property defines the seed value used for particles randomization. With the same seed, particles effect will be identical on every run. This is useful when deterministic behavior is desired over random behavior.

The default value is 0 when \l {ParticleSystem3D::useRandomSeed}{useRandomSeed} is set to false, and something in between 1..INT32_MAX when \l {ParticleSystem3D::useRandomSeed}{useRandomSeed} is set to true.

Note
This property should not be modified during the particle animations.

int QQuick3DParticleSystem::startTime ( ) const

\qmlproperty int ParticleSystem3D::startTime

This property defines time in milliseconds where the system starts. This can be useful to warm up the system so that a set of particles has already been emitted. If for example \l startTime is set to 2000 and system \l time is animating from 0 to 1000, actually animation shows particles from 2000 to 3000ms.

The default value is 0.

int QQuick3DParticleSystem::time ( ) const

\qmlproperty int ParticleSystem3D::time

This property defines time in milliseconds for the system.

Note
When modifying the time property, \l {ParticleSystem3D::running}{running} should usually be set to false.

Here is an example how to manually animate the system for 3 seconds, in a loop, at half speed:

\qml ParticleSystem3D { running: false NumberAnimation on time { loops: Animation.Infinite from: 0 to: 3000 duration: 6000 } } \endqml

\qmlproperty bool ParticleSystem3D::useRandomSeed

This property defines if particle system seed should be random or user defined. When true, a new random value for \l {ParticleSystem3D::seed}{seed} is generated every time particle system is restarted.

The default value is true.

Note
This property should not be modified during the particle animations.
