About actor

Hello, how can i make my actor die when he fall on the ground after a long fall? Sorry for my english, i'm french... 

The idea is to store when it first began to fall and at the end see how large it is. You can do it with one number attribute. Something like (Fall being the number attribute):

always
  if (Fall >= 0)
    increment Fall by 1
  if y-speed > 0
    if Fall = -1
      set Fall to 0
 otherwise
   set Fall to -1

When self hits top of tile
  if Fall > 100 (or whatever number you want)
     kill self

You are very strong... It was very simply for you... Thanks you!

You may say that i abuse but... And if my actor make a jump before to fall, it's always the same thing? (sorry, i'm new in Stencyl...)

Sorry, but I can't understand what you wrote. Jump before to fall? Do you mean double-jumping?

Does your behavior works after a jump too, or he's working only when the actor falls from a platform? (sorry, i take your time... :-) )

Sorry, I tested your behavior, and everything is ok... You're a monster, and I'm a true noob... Thanks you very much!

I'm happy to help.
