Still could use some help :/
Look into a value that dictates what direction you are blocking in and then play with the value.
I've done exactly this, there are 2 values that determine this, 2nd is always bigger than the 1st one, for example, attack and block direction values are exactly one under another.
ATTACK DIRECTION
0x123450 = 250
0x123454 = 251
BLOCK DIRECTION
0x123458 = 310
0x12345C = 311
Problem is that they are client side, if you were to freeze these values it would look like you always block at that particular position determined by those 2 values, but sadly it's only client side. Tested it with 2 players if you host and do that, you can have some funy looking blocking gestures, but if you join it won't work, you will block how you actually move your mouse...
