I'm attempting to make a race that blends in with the surroundings if certain conditions are met, in this case standing still for more than a certain amount of time. I have all my floats set, and a possible timer, but I'm not sure where to go from there.

Any help would be appreciated :3

Have a timer that slowly decreases the Alpha until it reaches 0 or whatever your minimum is. (Nice fading effect)

Check if the player moved in OnPlayerRunCmd and reset his alpha.

Ownz method would make the player visible if he gets knocked around by something. Don't know if you want that.
