The ParticleMotionGravity object moves particles towards a point. More...
This element was introduced in Qt 4.7.
This motion attracts the particles to the specified point with the specified acceleration. To mimic earth gravity, set yattractor to -6360000 and acceleration to 9.8.
The defaults are all 0, not earth gravity, and so no motion will occur without setting at least the acceleration property.
See also Particles.
acceleration : real |
This property holds the acceleration to apply to the particles.
These properties hold the x and y coordinates of the point attracting the particles.
