    My first game in processing.

    Instructions:
    1)LEFT key to move Left
    2)RIGHT key to move Right
    3)X to shoot

    The game is still under development. So the tank doesn't explode (u r in God mode :) ).Happy shooting!

    hello! awesome project!

    i was just curious on how i would manipulate your code so instead of a few shots each asteroid would get destroyed on a single shot ?

    do you know what i mean ?

    any help would be great thank you!

    Hey!
    I was wondering if it were possible for you to explain/go through the code with me? as I'm currently study this type of Java.
    Cheers!
