Complete the box3DTileTopCollision() function and extend it to take into account collisions with the other faces of the tile. The version given in the chapter leaves some of the work unfinished. See if you can complete it. Then finish it off by doing some of the easier work of detecting collisions with the other faces. Note that there are only two other possible face-face collisions. Attending to them should be reasonably straightforward, but don’t forget that the top edge is not parallel to the ground.
