That sums it up pretty nicely. It's the details where it gets complicated.

For sake of collision detection, the character is represented by a
sphere, so basically there is just a single point where it touches the
ground, in the center of the character's bounding box. That means, as
soon as the center moves over the edge of the tile, it begins to slide
downwards.

Of course, usually you'll have another tile right next to that tile,
so by going over the edge of one tile you are now on another tile and
nothing should happen. For some reason, this is not the case with the
current code. This could mean that the tiles that get checked for
collision are not the tiles the character is actually on. I should
probably increase that area just to check ... but of course for
efficiency it is important to really only check probable tiles.

Oh, btw. all of this is going on in world/moving.cc, in case somebody
wants to have a closer look.
