Update 2 - Added Target Lock system

Thinking of keeping track of updates as slowly adding features to the game.

This time added Target locking including movements such as left and right strafe, foward, side and back roll and forward, side and backward jump.

Will probably need more tweaking later to make movement more fluid.

One small point consider during this update was how to show target is target locked. Now day alot of game uses the white dot. I don't really want it to block the npc character too much yet still need to able to show and tell if its target locked.

Had consider using ground based target lock at one stage. But then thought it need to have body part target locking in the future then it might not be a good solution.

Might make changes to this in the future if thought of anything, otherwise will stick with the white dot for target locking for now.

Next up, to add hit reaction when npc hit by attacks.
