Question Changing data inside a custom tile on tilemap without affecting the whole asset

I have a custom tile with isEmpty. When I change it via

Code (CSharp):

1. GetTile<MyCustomTile>(myPosition).isEmpty = false;

it changes the whole same tile in the tilemap.
I know however, that changing color of a tile through SetColor will change only specified tile so I was assuming unity do have reference to each of them.

how am I supposed to do it ?, or is it just not how custom tile supposed to be used ?

 

Unless you use a third-party solution, all positions on a tilemap where you place a tile all use the same tile for initial data (when GetTileData is called).

When you use Tilemap.SetColor it affects only the tilemap's internal data. In contrast, if you change a field in a tile reference that you've obtained with GetTile then the Tile asset (a scriptable object subclass) itself is changed, affecting ALL positions where you've placed that tile.

TLDR; the stock Tilemap system doesn't support fields in a tile which will only affect one single position.

Hope that helps.

 

you have to refresh all tiles, after the tile is place it is drawn and set in stone until you refresh that position again
