Single '3 untouching circles' physics body?

[Kan98]

The current Box2D version of Solar2D does not provide x and y parameters for a circle body. You can either use a polygon shape to make it manually, or refer to the method mentioned by @aclementerodrguez.

Additionally, there is a version of Solar2D’s Box2D v3 that supports the circle body.

physics.addBody(object, "dynamic", {circle = {radius = r, x = x, y = y}})

This version also includes many features and changes compared to the current Box2D version in Solar2D.

Box2D 3.1 Ported to Solar2D for iOS and Android

We have successfully ported Box2D 3.1 to Solar2D, which now supports iOS, Android, osx, windows. Compared to Box2D v2, Box2D 3.1 has seen a significant performance improvement. You can download and test it here: Box2D 3.1 for Solar2D We hope to merge this version into the official release, but we are currently unsure of how to proceed to allow Box2D v2 and Box2D v3 to coexist.
