I’ve been working on a PVZ game for fun, and I’ve been trying to add in the code that prevents you from placing plants on tiles where plants already exist. I’ve created a variable called “CanPlant” and I’ve tried setting it to false whenever the player overlaps a plant, but it only ever works on the last peashooter I’ve placed.
If I have two peashooters, I cannot place another one on top of the last peashooter I just placed, but I can place it on any peashooter placed prior to it.
I also tried creating an invisible sprite that spawns when a peashooter spawns, and if you overlap with that it sets “CanPlace” to false, but the same issue arises.
Overlap blocks are very glitchy I recommend ditching them and checking for the closest sprite to detect overlaps instead. I’ve run into overlap issues many times, most notably with my isometric city builder a few years ago
You can read my topic on it for some more info. [Tutorial] Making an Enemy Follow Multiple Sprites it’s about making enemies follow multiple sprites by finding the nearest sprite. You can isolate the nearest sprite part of the code, combine it with a range the size of the sprite, and you get a perfect overlap function.
Oh yeah I tried that approach too, along with a coordinates based block is meant to prevent you from placing when the distance between the crosshait and peashooter are zero, both had the same issue as my other attempts…
Ooh, since I have no clue how arrays work, I have a very frustrating solution, I can spawn an invisible sprite on each grid, to which my crosshair must overlap with it to place a plant, once a plant is placed, the sprite on that tile is destroyed.
