The shapes in the Physics engine do not Stretch with the Object scale (except the Box shape, I think). So if I create a Polygon Shape, scaling the Objects sprites width does not scale the Polygon Shapes width making the physics objects sprites overlap.
Maybe the Polygon shape should scale with the objects bounding boxes, like the objects collision mask;
Or an addition Shape using the Objects Collision Mask;
Or using expression like “boundingboxright” inside the Behavior Tab where you can type in the Polygons dimensions.
