Cannot set rotation of instantiated GO when placing Tile on grid

Hello,

I'm using Unity 2018.1.2f1 64bit on Win10, and I'm using the Tilemap system to create tiles that have a BoxCollider2D on one of the sides. I've created a subclass of the Tile class where I place the GO containing the collider in the Instantiated Game Object field and the StartUp() method sets the position and rotation of the GO to the correct values, according to the position and rotation of the tile in the grid.

However, I can't obtain the current rotation of the placed tile anywhere, just the position; the rotation is always the same no matter how I rotate the tile when placing on the grid. Below is the relevant code block:

Code (CSharp):

1. public class Stage1EnergyBlock : Tile {
2. (...)
3.     public override bool StartUp(Vector3Int position, ITilemap tilemap, GameObject go) {
4.         GetGrid(tilemap);
5.         var tileWorldPosition = m_Grid.CellToWorld(position);
6.         go.transform.position = new Vector3(
7.             tileWorldPosition.x + 0.5f,
8.             tileWorldPosition.y + 0.5f,
9.             tileWorldPosition.z); //position works fine
10.         go.transform.rotation = transform.rotation; // this is where the rotation should be
11.         color = Color.white;
12.         return base.StartUp(position, tilemap, go);
13.     }
14. }

Am I missing something obvious? Or this is just not possible at the moment? The image below shows the problem: the first wall segment (top-left) is correct, the other ones are rotated and the associated GO does not rotate with them.

 

bump. I have the same problem

[Edit]
After some playing around I came up with this:

Code (CSharp):

1. public override bool StartUp(Vector3Int position, ITilemap tilemap, GameObject go)
2.     {
3.         TileBase tile = tilemap.GetTile(position);
4.        Matrix4x4 matrix = tilemap.GetTransformMatrix(position);
5.         go.transform.rotation = matrix.rotation;
6.  
7.         return base.StartUp(position, tilemap, go);
8.     }

 

Thank you you saved my day!! I had the same Problem, and i can't figured it out. Looking a week for a solution!
That's it.
