ok now they are moving^^ thank you
to the direction: i have a simple room and you play a ball who has to catch a cube. when you catch it one more enemy appears and "walks" along in this room and kills you when you hit it. so i think a movement only forwards is enough, because the enemys only have to change their move-directing when they hit a wall. I wanted to do this with "bounce" ...but i have no idea how to code this
i simply want to write a game like this in 3d: http://www.lewpen.com/game/
perhaps than it's easier to understand
