Question CompositeCollider2D's GetPathPointCount after calling Tilemap.SetTile is zero

I need to get my

Composite Collder 2D

PathPointCount

& paths on

Start

after generating a

Tilemap

on launch, but it's throwing an error because

PathCount

is zero.

After the Start method ends and the first Update call occurs, I can access this data, but I'd rather have this all done on Start and not put some flunky code in an Update method.

I've tried refreshing the

Tilemap

and calling

CompositeCollider2D.GenerateGeometry

but that doesn't help. I've tried both manual and synchronous generation.

When in manual, collision doesn't work (almost as if the generate geometry call didn't go through). When in synchronous the collision works, but again, the issue I'm experiencing is not being able to get path point count, and subsequently its paths.

Here's some example code to demonstrate the steps I'm taking

Code (CSharp):

1.         _tileMapWalls.SetTile( position + data.position, TileRepository.GetTile[data.name] );
2.  
3.         _compositeCollider = GetComponent<CompositeCollider2D>();
4.         _compositeCollider.GenerateGeometry();
5.  
6.         Vector2[] pathVerts = new Vector2[_compositeCollider.GetPathPointCount( 0 )];
7.         _compositeCollider.GetPath( 0, pathVerts );
8.         List<Vector2> _compositeVerts = new List<Vector2>( pathVerts );

ArgumentOutOfRangeException: Path index 0 must be in the range of 0 to -1.

 

Cheers, Melv, I just needed to call ProcessTilemapChanges when calling Rebuild.
