Create a clickable grid system? I tried creating a grid system by making each grid tile an individual sprite, but now I have over 1,000 sprites and it's making the game super laggy. I just need to be able to change the tiles individually to a different color on click and didn't know how to do this without making each tile a sprite.
You would still need tile sprites to represent the different colors but you shouldn't need that many of them and you can create that colored tile at Position Mouse.X and Mouse.Y
Do you have the grid event set up so your mouse cursor moves one grid space at a time?
