hi, i am trying to make a platform game. I am currently working on my enemies and i would like them to walk up and down the platform they are currently on. therefore my first thought was to get the object the sprite is currently colliding with, get its length and make the guy walk that far, so he walks the length of the platform and doesnt fall off. But my platforms are all part of a group and the collision detects if the sprite is colliding with a group member. How can i get the object the sprite is currently colliding with, so i can get its length?? i'm also open for different techniques to achive the same thing! Thanks for your help, i really need it
