Hi, it's The_Lord_King (it's an another account, I can't access the other...). Thanks for the answer it works like i want, but I have an another problem and i don't know how to solve it except with a lot of events so I hope there is a better solution.

This is the picture of what I've done. In my game, I want the sword rotate 90 from the character's angle, so I made a "angleDepart" variable (can be translated by "Start Angle").
All of this works expect the last event (when the sword's angle is greater than 270).
Thanks again ! :)
EDIT : I found the solution sorry for this post. I used "Is Clockwise from" compare.
