WebJan 7, 2014 · If I use a polygon collider, the center of mass of a rigidbody2d is no longer the center of the object. Thus, if I make calls to rigidbody2d.applyForceAtPosition, I cannot move an object forward with the parameters (position.x,position.y+1) (position.x,position.y-1) without also creating torque. WebJan 11, 2016 · This method works for triangles. It does not work for polygons with 4 or more vertices. A simple counter-example is a polygon with vertices (1,0), (2,0), (3,1), (0,1).

WebI was stuck with the same dilemma and using Adobe Illustrator wrote a script that places a small hole at the center of gravity of an irregular polygon. It worked great! After this iteration, I also added a few snippets to create the hole just above the center of gravity to ensure that the part balanced well when suspended from just that one point.
