Hi,
Either there is a bug, or I still don't understand the coordinate system.
I created a triangle like this:
which is in my opinion convex and CCW. But I got error "Polygon should be convex and should have a CCW winding order."
When creating the polygon CW, works fine without errors:
Either there is a bug, or I still don't understand the coordinate system.
I created a triangle like this:
local triangle = b2.PolygonShape.new() triangle:set( 0, -20, -5, -10 5, -10, ) |

So you don't need to treat this as bug.
It would help newbies like me.
