@UberLou Some of the issues I have are around collision boxes etc... it is hard to tell the size of the character during map design... also hard to assign the platformer behaviors, etc... when I can't see the size and collision box for the characters. So far I have been exporting everything as png and importing them as frames. But it takes a lot away from the smoothness of the animation and you have to do a lot of playing with the speeds.
When you bring in your .scml do you assign the platform behavior, etc... and if so to which objects? My platformer needs to be as precise as possible because it does count a lot on tricky jumping and other stuff that heavily leverages collisions.
