Objective
Currently, regular polygons don't have their own collider shape. Instead, the
From<RegularPolygon>
implementation computes the convex hull and creates a convex polygon from that. This may not be the most efficient approach however, as some computations can be simpler and more efficient if the polygon is known to be regular.This PR adds a custom shape implementation for the 2D
RegularPolygon
primitive.Solution
Add a
RegularPolygonWrapper
type that is used as the internal representation for the custom regular polygon shape. The custom shape uses the ID2
.Migration Guide
If you had a custom Parry shape using the ID
2
, you might need to change it, because the ID is used for regular polygons.
