Hi! First of all EXCELLENT WORK 🙂 I'm so happy working with Spine & Corona.
Nate, I think there is a mistake in SkeletonBounds.lua in the next lines:
119 if self:polygonIntersectsSegment(polygon, x1, y1, x2, y2) then return boundingBoxes[i] end
141 local nn = polygon.length
in my case these always return nil I changed it to next ones
119 if self:polygonIntersectsSegment(polygon, x1, y1, x2, y2) then return self.boundingBoxes[i] end
141 local nn = #polygon
Now is working fine for me 🙂
Maybe I'm doing something wrong but I want to tell you 🙂
