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:
ParticleEmitter3D {
...
velocity: TargetDirection3D {
position: Qt.vector3d(100, 0, 0)
normalized: true
magnitude: 15.0
magnitudeVariation: 5.0
}
}
|
magnitude : real |
This property defines the magnitude in position change per second. Negative magnitude accelerates the opposite way from the position. When the normalized is false, this is multiplied with the distance to the target position.
The default value is 1.0.
See also magnitudeVariation.
|
magnitudeVariation : real |
This property defines the magnitude variation in position change per second. When the normalized is false, this is multiplied with the distance to the target position.
The default value is 0.0.
See also magnitude.
|
normalized : bool |
This property defines if the distance to position should be considered as normalized or not. When this is false, distance to the position affects the magnitude of the particles velocity. When set to true, distance is normalized and velocity amount comes only from magnitude and magnitudeVariation.
The default value is false.
See also magnitude and magnitudeVariation.
|
position : vector3d |
This property defines the position for particles target.
The default value is (0, 0, 0) (the center of the emitter).
See also positionVariation.
|
positionVariation : vector3d |
This property defines the position variation for particles target.
The default value is (0, 0, 0) (no variation).
