Devlog #3 - Doing the undoing

Hey all! 

Last update, I was working on path connecting, but I needed the previous tile placed so I pivoted to work on "undo"ing first! If I was storing my list of moves already, I could easily grab the previous tile placed.

Setting up the initial undo was easy - storing every tile placement in an undo_history array and reading it backwards / assigning the tile to the grid when I hit undo.

But after testing, I realized undoing a line of paths you just placed while clicking + dragging gets very tedious to undo one tile at a time. 

Instead, I setup a multidimensional array storing every tile placement into it's own undo_stack array and then stored that undo_stack into the undo_history array.

If you single click, it's a single item array. If you drag + click, placing multiple tiles, it stores them all in an array until you release the mouse button.

Thanks for reading! Would love to hear your thoughts!!
