- \qmlclass Move QSGMoveAffector
- \inqmlmodule QtQuick.Particles 2
- \inherits Affector
- \brief The Move element allows you to set a new position, speed or acceleration on particles
-
- You'll often want to set the 'once' property to true for efficiency in the case where you just
- want to set the parameter. Otherwise, the parameter will be needlessly set to the same thing
- every simulation cycle.

-/*!
- \qmlproperty StochasticDirection QtQuick.Particles2::Move::position
-
- Affected particles will have their position set to this direction,
- relative to the ParticleSystem. When interpreting directions as points,
- imagine it as an arrow with the base at the 0,0 of the ParticleSystem and the
- tip at where the specified position will be.
