hi, i have this project to do. i'm trying to program the game "stupid zombies"!! if ever seen it its prety much anew game in the andriod application on the i-phone. there you have the shooter standing on the buttom left hand corner and he is shooting those zombies. now to aim on them you just hover with the mouse over the point that you would want the bullet to go to an you click with the mouse. then the shotgun fires up. and you could see the bullet traveling from the shotgun towards the target. and thats exactly what i need/looking for!! thank you
