I'm trying to detect how fast is player moving when he attacks. Only 2 times while i test it, movementX and movementZ != 0. In all other tested situations prev and current positions, movementX and movementZ - all was identical. And what is "chasing"? I have some troubles with English, so.. I can't properly understand what does it mean. But looking at chasing coords, i think, that may be it is what i need to get speed.

P.S. After more testing i'm almost sure that i can use distance between chasing coords to get speed. But it will be better if somebody will confirm it
