A* Pathfinding Help

  1. What do you want to achieve? Make A Grid

  2. What is the issue? I don’t really know how to.

  3. What solutions have you tried so far? I looked everywhere but no one seems to have a tutorial on it.

Hello everyone! I was just going to make a A* Pathfinding System but then I came into a problem.
Every A* Tutorial has a preset grid, and for the ones that don’t, they use different functions from different languages. I’ve got the A* Pathfinding Algorithm in my head. However Roblox doesn’t have a preset grid. Is there any efficient way I could make a grid that won’t literally freeze my game?

Edit : I think I could simulate parts, like storing positions and sizes to then later put them in. Which would be pretty nice if the map is big.

(Sorry for short post I didn’t really know what I was going to say.)
