Reversing

To begin reverse call the function StartTimeReversal, to end reverse call EndTimeReversal.

If time passed after reverse begin > MaxReverseDuration then, EndTimeReversal is called automatically. After EndTimeReversal is called, the actor have to wait for MaxReverseDuration seconds before it can reverse again.
As soon as TimeReversal is started, OnReverseTimeStarted delegate is triggered, with the help of this delegate you should toggle or disable physics properties on the actor like bSimulatePhysics and bEnableGravity. You can toggle back these properties through a delegate OnReverseTimeEnded, which is called instantly after time reversal ends.
