Tlecoz a raison, ça calcule trop. Je suis une quiche en AS donc je ne critiquerais pas ton code mais si au moins il y avait un minimum de commentaire, je serais moins perdu.

Ceci dit, 415 lignes de code c'est effectivement un bel effort

Hello,

J'avous ne pas avoir pris le temps de lire le code, je me suis contenté de regarder le swf. D'une part, je ne vois pas trop dans quel cas appliquer ton anim, d'autre part le temps de calcul est enorme ! C'est casiment instantané sur les 4 premiere elements, mais ca prend plus de 5 seconde a partir du 7eme blocs....Pas trés exploitable quoi !

je te suggère d'aller voir du coté de APE (Actionscript Physic Engine) :
http://www.cove.org/ape/demo1.htm

ou Motors :
http://lab.polygonal.de/category/physics/

ou encore Box2DFlash qui vient de sortir et qui m'a l'air assez genial :) :
http://box2dflash.sourceforge.net/

Tu verras que c'est quand meme un autre niveau (sans vouloir t'offenser)

2/10 pour l'effort
