# ● Ce système de "rang" marche en scannant une zone semie circulaire située en face de l' événement.

#    La vue est crée dans chaque événement est égale au radian du cercle

#    L' équation est: (Px-EX)^2 + (Py-Ey)^2 = radius^2

#    Si le radian est supérieur ou égal à la Vue, le joueur se trouve dans le cercle.
