hi, i am trying to make an above-view tank game. the only thing that i have made so far is a tank that moves by keypress. now i need to know how to make walls that the tank its bullets(once i make them) cant go through. does anyone have a tutorial i could print out so i can learn it whenever i have free time at school? i know how to do neither, but should i use hitTest or like a tile-based game? how does a tile-based game work? can i get a good tutorial for that to print out? the one edmacks site is broken up and is hard to print out even tho im still looking into it...thank you.
