"Clickable" only means that you cannot click on character itself, but it does not disable any other controls.
If you want a state where controls do not work, you need to introduce some global variable (like, "IsDead"), and test it in on_mouse_click, before the place where you call ProcessClick and similar commands, to prevent these.
Same, if you have keyboard controls for player walking and interacting with the world, you will have to test this variable before doing anything.
