How would I solve this problem?

[Mathias_Westerdahl]

Well, personally, I’d set the “lock rotation”, but that might be due to the fact I’m used to having a round shape at the bottom of my characters. In 3D games, a capsule is very common, but since Box2D doesn’t have one, I used two spheres and a box. A round shape at the bottom will help traversing smaller obstacles, should there be any. also, it fits more with the rotation motion of the legs of my character. And, it will get a lot easier to resolve collisions

Then, I experienced problems with switching from box to sphere for my kinematic body (It falls asleep every 33 frames):

Kinetic sphere collision resolve issue (DEF-2114)

Hi again team! While fiddling with my platformer code, I noticed a strange behavior when resolving kinetic sphere collisions. Backtracking the code, a lot of which I borrowed from the Platformer example, I found that the issue is there as well. Simply changing the hero’s collision shape from a box to a sphere, makes the platformer collision behave strangely. Every so often, you’ll experience a “fall” animation getting triggered. When debugging the code for clues, I noticed that in the box sha…

And, even if I ignored that, I found other problems with normals in tilemaps:

Tilemap collision normals? (DEF-2104)

To add some more examples, I tested a flatter slope, which exposes the problem a bit more I think. Here the tiles are at “half height”, i.e. 32x16 pixels, and they match up perfectly pixelwise, but not physics wise. I see two problems. 1, one tile is “thinner” than the other. 2. at the top right corners of the tiles, the slope of the physics becomes flat, making it an uneven surface within the tile.

FWIW, my plan is to replace my kinematic body with a dynamic one, and see if I can get the platformer behavior I want anyways. Currently, the kinematic body doesn’t have any velocity, so it doesn’t affect other objects the way I’d like.
As for the tilemap normal issue, it’s not very high priority right now, but if it happens to you please let us know!
