    Cool java: collision listener for a game


    i have been making very simple games for java for awhile now but i have come across yet another problem.

    all the games i made just had about 3 or 4 objects that needed collision detection... so i just put it in the while loop in the run() method of the applet.

    well that worked out fine but as i am getting more in to a more advanced game it is starting to get messy(and slower). i intend to have alot of collisions in this game. then i look at a game like mario 64 and think that they couldnt have checked for collisions in every step. so i figured there is some way to write a listener(like a mouse listener or a key listener) that could wait for some variables to equal something then trigger the action.

    i have searched far and wide(on the web..) for how to do this but i have found nothing.

    is the only way to detect collisions in an infinite loop or is there another way?

    Whenever an object moves in the game that can collide with another, you should check for a collision. So whenever event invokes movement on such an object, you should check for a collision (for instance, if the player is moved by keys, you check the if the player has collided with anything).

    Hope that helps!

    Happy coding!
