Is there a way to structure a rule such that it only activates if one of the tiles defined in the region is actually empty?
I have a rule file with a 2x2 area in my regions:
On the input I have 2 diagonal blocks using the top left and bottom right corner for input_Ground:
On the output I have a 2x2 output set of tiles for my output_Ground:
I know the rule will work and replace the 2 corners correctly if the 2 empty spots are populated with any other tile from any tile set. However, I want to create a rule that says those 2 spots must be empty and have no tile at all.
Perhaps a variant on inputNOT_Ground could be used? Something like inputEMPTY_Ground where one could specify certain tiles as part of a defined region as being required to be empty? Since by default a defined region is inputANY unless a specific tile is placed in one of the input layers.
