An abandoned project that I made a while ago, it's inspired by this game called Rebuild where you lead a bunch of survivors in a zombie apocalypse, secure the town, yada yada... I never really got to finish this lol, so it's just watching a town descend into a zombie apocalypse with groups of survivors moving around, and variously getting eaten by zombies or starving to death Arrow keys to move the camera, click a square to select it and see range from that square. Press R to reset the camera if you get lost, though that's unlikely because I implemented camera restrictions. Comes with 3 sliders, gridsize, selectedrange, and scale. Gridsize is the side length of the square the grid is created in, selectedrange is the range that squares will light up yellow to a selected square, and scale is how big it all appears, basically a zoom function.
Original but if you use it it would be nice if you credit me :P The squares are rendered using stamps and the pen tool, which allows me to bypass the 300 clone limit but makes it hard to store information on each square without using lists, and it's hard to identify which square is which using just the list numbers, though thankfully I found an easy way to translate list numbers into position on the grid relatively early on. 40x40 grid size is the biggest I put it because it would lag and stutter horribly on larger maps, though you're welcome to bypass that limit by looking inside and changing the slider range (right-click on the slider while not in fullscreen). I advise you to not go past 50x50; because of quadratic growth, it will get very laggy very quickly. The most I think it'll even work is 100x100 and even then it has to go through 10,000 list items each frame, so you can imagine how laggy it is. Can be used for all kinds of stuff from boardgames to wargames to islands, whatever you can think of, grids are pretty nifty, just make sure it's turn-based because real-time and grids don't mix, period.
