A one-off extension for Team Fortress 2 that allows plugins to override the result of getting a
player's max speed, without mucking about with mult_player_movespeed attributes that may be
in use.
Originally written for a weapon overhaul project that adds a bunch of new speed modifying-behaviors, where applying attributes to change the speed would be cumbersome.
DHooks with detours currently has issues with returning floating point values; otherwise
I'd probably be using that instead. In the future, this extension will be replaced
with a plugin based on DHooks; the previously mentioned issues are no longer true.
Only tested and verified against Linux.
You get the one forward:
forward Action TF2_OnCalculateMaxSpeed(int client, float &flMaxSpeed);
Initially, this contains the full speed amount after the game performs its calculations. Manipulate it as desired; standard hook returns apply.
If you want to forcibly update a player's speed, create and perform an SDKCall to
CTFPlayer::TeamFortress_SetSpeed() and handle the change in the forward. You can
easily do this using TF2Util_UpdatePlayerSpeed in TF2 Utils.
