As you can see, i have made the map a lot more complicated, and the simulation runs quite accurately until you go under the overhang on the left side. Where you can jump through the bottom of that platform. Lets change that.

We need to add a hit detection for when the top of the character hits the bottom of the land.

Ok, now you can’t jump up through platform bottoms, but if you jump sideways into the hovering platform, you float down.

I will think on this matter for the next step in the tutorial.
