Here is the call graph for this function:

◆ duration()

int QQuick3DParticleAttractor::duration ( ) const

\qmlproperty int Attractor3D::duration

This property defines the duration in milliseconds how long it takes for particles to reach the attaction position. When the value is -1, particle lifeSpan is used as the duration.

The default value is -1.

signal

Referenced by setDuration().

Here is the caller graph for this function:

◆ durationVariation()

int QQuick3DParticleAttractor::durationVariation ( ) const

\qmlproperty int Attractor3D::durationVariation

This property defines the duration variation in milliseconds. The actual duration to reach attractor is between duration - durationVariation and duration + durationVariation.

The default value is 0 (no variation).

Definition at line 139 of file qquick3dparticleattractor.cpp.

◆ durationVariationChanged

void QQuick3DParticleAttractor::durationVariationChanged ( )

signal

Referenced by setDurationVariation().

Here is the caller graph for this function:

◆ hideAtEnd()

bool QQuick3DParticleAttractor::hideAtEnd ( ) const

\qmlproperty bool Attractor3D::hideAtEnd

This property defines if the particle should disappear when it reaches the attractor.

The default value is false.

Here is the caller graph for this function:

◆ positionsAmount()

int QQuick3DParticleAttractor::positionsAmount ( ) const

\qmlproperty int Attractor3D::positionsAmount

This property defines the amount of possible positions stored within the attractor shape. By default the amount equals the particle count, but a lower amount can be used for a smaller cache. Higher amount can be used for additional randomization.

signal

Referenced by setPositionsAmount().

Here is the caller graph for this function:

◆ positionVariation()

QVector3D QQuick3DParticleAttractor::positionVariation ( ) const

\qmlproperty vector3d Attractor3D::positionVariation

This property defines the variation on attract position. It can be used to not attract into a single point, but randomly towards a wider area. Here is an example how to attract particles into some random point inside (50, 50, 50) cube at position (100, 0, 0) within 2 to 4 seconds:

\qml Attractor3D { position: Qt.vector3d(100, 0, 0) positionVariation: Qt.vector3d(50, 50, 50) duration: 3000 durationVariation: 1000 } \endqml
