Hi, I don't understand why GreenFoot does not recognize the " Direction " class, maybe someone can help me to sort this out :)
This game is quiet simple, you have a car that you can control and you just have to avoid the other cars ( if a car touch yours, you explode and you loose the game )
Some parts of the codes may be in french, so if you need some explanation just hook me up.
Thank's for reading this.
I have got 3 actors, a Wombat ( which is my car ), Ennemi ( enemies' cars ) and Explosion.
