I'm too tired for my historians mind to try to find out how to calculate the tile coordinate on my map for any given mouse position. 64 by 64 pixels but it's not a square but a diamond, so about half of the 64x64 box in all four corners is not this tile and they're not even arranged neatly. Anyone with a solution?

@TommyvanSon Is there a way to rotate the coordinates 45 degrees so they're coordinates on a square grid?
@peterdrake thanks. I did consider this approach before but that would make my grid have even more unequal lengths per record and that caused problems on different places is my code.
@TommyvanSon Okay, how about this:
1. Use a formula to find an approximate answer. For example, the top of your upper right character's head is in row 1-3 and column 2-4.
2. Among the (9 or fewer) candidate tiles, pick the one whose center has the smallest Manhattan distance to the cursor.
@peterdrake This sounds promising. I will need to find a way to calculate the candidates. Never heard of 'Manhattan distance' but I may be able to use that to my advantage.Thanks
@TommyvanSon@mastodon.gamedev.place@peterdrake your idea was the thing I needed. I reversed the code to find a position for the grid coordinate so I had the decimal for a grid. Then I used that Manhattan distance your proposed to find which is closest. I can make it more efficient but it works! Thanks for the help!
