comme ca ca marche tres bien :
vide6._visible = false;
jauge._visible = true;
vide6.loadMovie("jeu_test2.swf");
this.onEnterFrame = function() {
charge = this.vide6.getBytesLoaded();
total = this.vide6.getBytesTotal();
pcent = Math.round((charge/total)*100);
this.jauge._xscale = pcent;
if (charge == total) {
this.vide6._visible = true;
this.jauge._visible = false;
this.onEnterFrame = null;
// action
}
};
