Anyone have an auto FPS that works after death? or where it enters FPS upon clicking a GUI button?

Either give link to model or the code? Thanks.

Your title does not make sense. Please give more detail, then provide a script.

You should be able to just put this inside a LocalScript in game.StarterPack:

while not game.Players.LocalPlayer do wait() end
game.Players.LocalPlayer.CameraMode = "LockFirstPerson"

By default LocalScripts will run when the Player respawns (i.e. "after death"), so the CameraMode will be set to LockFirstPerson as soon as they spawn.

Let us know if that isn't exactly what you were looking for, though.
