Jme - sdk - application mobile - attrape les ipod qui tombent
Description
Petit appli mobile avec le SDK 3.0. (Tomcat 6)
Il faut déplacer un petit panier afin de rattraper les IPod qui tombent du ciel :)
Ce code montre donc l'utilisation du ramdom, timer, graphics, vector, etc.
Utilisation également des sons.
