The only other way I could think of is read the sprite image off the tilemap at the prefabs position. Is there a way for the prefab to know its position or do I have to go through the entire tilemap at the beginning to set everything up? Thank you.
No there isn't. You will have to set up the prefabs manually / write a script to do it. We could probably add support for it if there is enough interest.
Could you please? I am currently using the script below to make the changes I need for the sprites and I feel like there could be an easier way within your system.
This code grabs the name of the sprite from the tile and calls SetSprite(spriteName) on the prefab.
Make sure to set the string value in the data tab for each tile to the sprite name from your collection, it won't work otherwise.Select your tilemap before pressing the button.
edit: updated code to flip tiles appropriately. It won't rotate 90 yet.
edit2: updated so it goes through layers as well
edit3: did the flags wrong the first time, fixed now.
