How can I set a event about my character die?

sure,now all the problem is it can disable movement right now after I use <= on the variable.
But the problem is if I can use a problem like"event tick" or "event hit"some events that can apply this to be happened and disable movement.Just the event that let the engine know that my health is 0 right now and I have to be dead,for example,if I use event hit,I need to be hit again and go dead when my health is zero.So sort of the event tick that event that can run the function.
