Well, the thing is, when trigger_push fails, I won't bounce up again, though that isn't what makes me die.
That's when I gain too much height, but I can see with all other maps, the trigger_push never fails and they never recieve any damage either.
They don't use water nor gravity.
Edit:
The water works perfectly, I do not gain more height and now I have to actually jump to trigger the trigger_push, whereas before I didn't need to jump wich was something I didn't like.
By the way, is there some way to make the water make no sound?
I have "Move Sound: No Sound" and "Stop Sound: No Sound".
Again, thank you all for your great help, you've saved me a lot of headaches!
