For applying friction proportional to the particle’s current velocity
|Import Statement:||import QtQuick.Particles 2.0|
|factor : real|
A drag will be applied to moving objects which is this factor of their current velocity.
|threshold : real|
The drag will only be applied to objects with a velocity above the threshold velocity. The drag applied will bring objects down to the threshold velocity, but no further.
The default threshold is 0
