For modders: Fixed Animstate for multiplayer

[JOMBIX]

Well, I saw this happening in a few mods that are using the OB engine 2007, where people have 9 way animations screwed up directions, the problem was that the animations had a reverted value, cause your thirdperson model to rotate, while the legs are going to the opposite direction of your movement.

Basically just replace your whole [b]hl2mp_playeranimstate.cpp[/b] with the code below (This problem doesn't exist for the Template version of the mods):

Well now isnt that nifty.

Does this fix the spastic behaviour you can see in gmod when you walk in 3rd person?

I'm going to check to see if I'm incorrect, and use your code anyway. I'll fill you in on the details.

[QUOTE=amcwatters;27079043]Your code above does nothing about the entirely incorrect playback rates for animations, which I can't seem to find any good fix for. Even my own fix (see below) only fixes it for other players that you can see in firstperson, but not yourself in third.

My animstate is animations directions. Not the playback.
