How can I modify tilesource collision shapes via script?

Edit: nvm, although “hull” is documented as a valid shape type to get, it looks like it’s unimplemented:

                  case dmPhysicsDDF::CollisionShape::TYPE_BOX:
                      dmScript::PushVector3(L, dmVMath::Vector3(shape_info.m_BoxDimensions[0], shape_info.m_BoxDimensions[1], shape_info.m_BoxDimensions[2]));
                      lua_setfield(L, -2, "dimensions");
                      break;
                  case dmPhysicsDDF::CollisionShape::TYPE_CAPSULE:
                      lua_pushnumber(L, shape_info.m_CapsuleDiameterHeight[0]);
                      lua_setfield(L, -2, "diameter");
                      lua_pushnumber(L, shape_info.m_CapsuleDiameterHeight[1]);
                      lua_setfield(L, -2, "height");
                      break;
                  case dmPhysicsDDF::CollisionShape::TYPE_HULL:
                      break;
                  default:break;
              }
          
              return 1;
          }

Is there a special name for the collision shape used by tilemaps? I’m trying to use physics.get_shape:

pprint(physics.get_shape(msg.url("#tile_collisions"), "/main/levels/level1/level1_map.tilemap"))
