I want to my game crash when player enter is one room so is there any way to do it?
if you mean actually close the game, you should be able to just call the quit game node.

There is also the console command EXIT you can call

Low entry extended standard library (free) has a crash node in it.

`debug crash` in console
deliberately reference a null pointer?
