Need help creating a script that generates a map grid. A similar script was created by @nin900500, and it looks like this
Where could I start on how this could be done, or maybe someone already has code that generates such a grid and would share it. I tried to do it myself, but the only effect I managed to get is this one
I’m completely dissatisfied with it, it’s not what I wanted to get and I’m ashamed to brag about it 
. For any mistakes I apologize I am not very good at English.
