How to stop first person controller (from standard asssets) move when game over condition?

I have a question about first person controller, which i have from standard assets. How can i stop moving this controller after game over condition in my game?
That is after my health points are 0 i want to stay in one place and cant walk, jump, etc, and next i will set my game-over screen. I think that i must set something in script and function death() but how to do that with fpc controller?

Thanks for help!

 

Try this

FPSObject.GetComponent<ScriptName>().enabled = false;
