Hello! I've asked this question twice before. The first time I was linked to a forum search which only had one relevant topic, and that topic was for construct classic so I couldn't follow it. The second time I was linked to a post about grid based character movement, but that wasnt using a grid it was just turning and moving a certain amount of pixels and I can't see how I could use that to place blocks. So I ask again, how would I make a game in which the player can destroy, or place blocks but ONLY in a grid like for example, Minecraft, Terraria, etc. Please don't link me to any other "slightly" relevant posts as I don't want a re run of before.
