In this tutorial you will learn how to generate walls through actionscript. There height will change and you can make them go for as long as you want. I am using Flash 8 but Flash MX 2004 will work as well. This isn't the best way to do this, it is just the way I find easiest.
I've made walls for my game, but I need the char to not to enter from any side. - I'm guessing that what I have to do is subtract the char's x/y coordinates by the wall's and if it's pos/neg, a boolean will tell the script to 'move' the char in the appropriate direction. Is this right? How do I actually do this?
