@Bankworthy: Yeah, the new AI is pretty complex compared to the old stuff. I plan to make a tutorial video about it soon. There is already a function that finds all tiles in range of the selected target called Find Path to Tile In Range. In this function all such tiles are stored in the Indexes With LOS integer array. This is done in the first part of the function, while the second part finds the preferred tile to attack from based on the Preferred Range variable of the current unit. Instead of doing this second part you should loop through all indexes in Indexes With LOS and find the one with the best cover instead. After this continue the AI event graph as normal.
