Constructor & Destructor Documentation

◆ QQuick3DParticleTargetDirection()

QT_BEGIN_NAMESPACE QQuick3DParticleTargetDirection::QQuick3DParticleTargetDirection ( QObject * parent = nullptr )

\qmltype TargetDirection3D \inherits Direction3D \inqmlmodule QtQuick3D.Particles3D

For specifying a direction towards the target position.

Since: 6.2

This element sets emitted particle velocity towards the target position.

For example, to emit particles towards position (100, 0, 0) with random magnitude between 10..20:

\qml ParticleEmitter3D { ... velocity: TargetDirection3D { position: Qt.vector3d(100, 0, 0) normalized: true magnitude: 15.0 magnitudeVariation: 5.0 } } \endqml

Definition at line 35 of file qquick3dparticletargetdirection.cpp.

Member Function Documentation

◆ magnitude()

float QQuick3DParticleTargetDirection::magnitude ( ) const

\qmlproperty real TargetDirection3D::magnitude

This property defines the magnitude in position change per second. Negative magnitude accelerates the opposite way from the \l {TargetDirection3D::position}{position}. When the \l normalized is false, this is multiplied with the distance to the target position.

The default value is 1.0.

See also: magnitudeVariation

Definition at line 123 of file qquick3dparticletargetdirection.cpp.

◆ magnitudeChanged

void QQuick3DParticleTargetDirection::magnitudeChanged ( )

signal

Referenced by setMagnitude().

Here is the caller graph for this function:

◆ magnitudeChangedVariation

void QQuick3DParticleTargetDirection::magnitudeChangedVariation ( )

signal

Referenced by setMagnitudeVariation().

Here is the caller graph for this function:

◆ magnitudeVariation()

float QQuick3DParticleTargetDirection::magnitudeVariation ( ) const

\qmlproperty real TargetDirection3D::magnitudeVariation

This property defines the magnitude variation in position change per second. When the \l normalized is false, this is multiplied with the distance to the target position.

The default value is 0.0.

See also: magnitude

Definition at line 147 of file qquick3dparticletargetdirection.cpp.

◆ normalized()

bool QQuick3DParticleTargetDirection::normalized ( ) const

\qmlproperty bool TargetDirection3D::normalized

This property defines if the distance to \l position should be considered as normalized or not. When this is false, distance to the \l position affects the magnitude of the particles velocity. When set to true, distance is normalized and velocity amount comes only from \l magnitude and \l magnitudeVariation.

The default value is false.
