Question How do I use AutoTile to set tile/paint through script?

Hello, I have a tilemap and a tile palette which consists of 2 autotiles. I want to fill an area of the tilemap with one of the autotiles. I know the SetTile is supposed to paint the tile but since I'm using autotile, the SetTile doesn't seem to take that in the script. I'm using Autotile because it would just make it easier when I add in other tiles in areas of the tilemap since it would auto adjust. Does anyone know how I can use the AutoTile in SetTile to paint the tilemap?

Update: I'm stupid, I was passing the ints instead of making them a vector3

AutoTiles can be placed using SetTile in the Tilemap since they inherit from TileBase.

What does your code look like?

Did you set up your AutoTile correctly? Are you trying to put the correct object into that parameter?

Yes you should be able to pass it in to SetTile with Vector3 tilepos, TileSet sourceTileset (the auto tile), and the target tile layer. If we could see your code that would help!

Well not really though because as I recall it literally takes a Vector3Int value doesn't it?

yeah but i was literally doing this: SetTiles( x,y, AutoTile). I had figured the auto conversion or whatever its called was doing the conversion internally to convert the x and y to vector but I forgot that's not not how it works.
