I want to make the screen shake and the players to slowly get hurt when the timer runs out. I'm using an env_shake and a trigger_hurt but I don't really understand how I can get this to work. This is what I have at the moment, but the screen doesn't shake, and it doesn't even say stalemate and end the round. The timer runs out to 0, the trigger_hurt is enabled, but that's it. What do I do?
