Constructor & Destructor Documentation

◆ QQuick3DParticleAffector()

QT_BEGIN_NAMESPACE QQuick3DParticleAffector::QQuick3DParticleAffector ( QQuick3DNode * parent = nullptr)

\qmltype Affector3D \inherits Node \inqmlmodule QtQuick3D.Particles3D

Affectors modify the attributes of particles during their lifetime.

Since
6.2

The Affector3D is an abstract base class of affectors like \l Gravity3D, \l Wander3D, and \l PointRotator3D.

By default affectors affect all particles in the system, but this can be limited by defining the \l particles list. If the system has multiple affectors, the order of affectors may result in different outcome, as affectors are applied one after another.

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.

◆ enabled()

bool QQuick3DParticleAffector::enabled ( ) const

\qmlproperty bool Affector3D::enabled

If enabled is set to false, this affector will not alter any particles. Usually this is used to conditionally turn an affector on or off.

The default value is true.
