How the node's collider2d turns its mesh into a shape: the shape a fit takes, the edges a polyline keeps, how a convex_polygon and a voxelized outline are read, and what a triangle_mesh tidies first.

In a scene, mesh_collider2d is the node key that applies it. A script reaches each property below as a field on node.mesh_collider2d: reading one asks the running component, and assigning one leaves the rest alone. The whole table is node.mesh_collider2d.get() and node.mesh_collider2d.set(table).

Properties

property	type	default	description
`connected_components`	bool	`false`	Work out which triangles form each separate piece of the mesh
`drop_bad_topology`	bool	`false`	Drop the triangles that stop the mesh's edge topology from being built
`drop_degenerate_triangles`	bool	`true`	Drop triangles that name one vertex twice; merges vertices too
`drop_duplicate_triangles`	bool	`true`	Drop a triangle whose three vertices another one already names; merges vertices too
`fill`	enum	`solid`	Whether voxelizing an outline fills its inside or only its edge, for voxelized_mesh and a vhacd or voxels decomposition One of `solid`, `surface`.
`fill_cavities`	bool	`false`	When a solid fill floods an outline, leave the holes it walls off empty
`fix_self_intersections`	bool	`false`	When a solid fill floods an outline, handle the places it crosses itself
`merge_vertices`	bool	`true`	Merge vertices at exactly the same place when building a triangle_mesh
`oriented`	bool	`false`	Treat a triangle_mesh or polyline as one-sided: the winding decides which side is solid, counter-clockwise enclosing the solid
`topology`	bool	`false`	Build the mesh's half-edge topology
