I need a method that works like the getOneIntersectingObject()-method, but not if the images intersect, rather, when they are touching each other. Thats for my walls.

A new method was added in Greenfoot 2.3.0, isTouching(). I've never used it but it might be what you are looking for.
Thanks.
There is no method to do what you want (you have to program it yourself). The new 'isTouching' method is basically a shortcut for '!getIntersectingObjects(class).isEmpty()' or for 'getOneIntersectingObject(class) != null'.
Usually, what you would do is go ahead and move the actor, then check for intersection. If intersection occurs, move the actor back. This is done all within the same act cycle; so, the actor appears to just stop at the wall.
Great idea! Thank you!
