OptionalisInternalConstructor: booleanPosition of the center around which to orbit. Evaluated over particle system lifetime.
Speed at which to push or pull the particles towards/away from the center. Evaluated over particle lifetime.
Determines the speed of rotation around each axis. The speed is specified in "turns" where 0 = no rotation, 0.5 = 180 degree rotation and 1 = 360 degree rotation. Evaluated over particle lifetime.
Marks the object as dirty.
Flags specifying what kind of member was changed.
Allows modifying this object multiple times in a row in a scope, without marking the object dirty immediately. Dirty flags are accumulated and the object is marked dirty at the end.
The scope where the object is modified.
