One of the features I would like to see in GE is a way to rotate an actor so that we do not need to load multiple animations for different angles. Broadly speaking, it should be enough to have a single "angle" variable so that there is a standard GE function on the following lines available:
Rotate("Actor Name", Angle);
It would save a lot of effort for those top-down shooter games where a smooth animation a very large number of animations for every animation sequence in the game.
