Can someone point me to an existing AGS mouse-controlled paltformer engine? The ones I know are keyboard-controlled. I've come to realize that it's much more tricky to implement than I thought, since the pathfinder doesn't work well on very thin walkable areas.
Only one I can think of is: Until I Have You (http://www.adventuregamestudio.co.uk/forums/index.php?topic=51520.msg636504170#msg636504170)
EDIT: Oh, sorry. Didn't read the "engine" part... But maybe they can help you get on the right track. ;)
