Hey everyone,

is there any plan to have an updated Box2d with all the things currently missing like joints, etc?  
I think this is one area where Defold is really lacking atm.

I believe @Mathias_Westerdahl has some plans to perhaps one type of joint (rope or spring?). I heard him discuss that earlier today. It would in that case be a code-only implementation to start with without editor support. But it was only a casual discussion and nothing decided yet.

Agreed. This and improved tilemaps.

There is a bug where the tile seams (where two tiles meet) give the incorrect collision response. See [this thread](https://forum.defold.com/t/directional-platforms-help/18764/16). I’m guessing this is a Box2D bug, but maybe it could be fixed by improving the tilemap \> Box2D fixture conversion (so there are less/no seams)?

@Mathias_Westerdahl knows more about how this works and can give feedback

I’m a new user and a very big fan of the Defold project so far!

I would love to see joint types implemented from Box2D - even if it’s only a code-only.

@britzl, are there any news on this?

No, no news I’m afraid. I started doing a Chipmunk 2D extension with joint support. It’s far from finished and it would be code only:

[https://github.com/britzl/chipmunk2d-defold](https://github.com/britzl/chipmunk2d-defold)

Check the example. If there’s interest I can continue to work on it.
