How to move to the other side when collide?

[7Heroes]

Hello, heres my project, i only need that my player moves to the other side when collide with a wall, the same thing that happens with Lemmings when they collide with a wall.

In the file there´s a group called WALL COLLIDE, can someone tell me what to do?, i think maybe i have to negate some events, but im not really sure, anyway, thanks!

OK, First off you are doing it wrong of you want to detect the collision on the wall. Look at the tutorials>>> on the links sidebar there. You'd need detectors, and don't use the animated character as your object, use a rectangle instead so that the animation's overlapping the wall doesn't mess it up.

A detector sounds good!, i think that will work.

I know about the sprite thing too, i´ll redraw the sprites, i dont really feel that i need to insert a mask instead, i´ll check that out later, but thanks, the detector should be do it!
