Grid Building System - City Builders, RTS | Unity Tutorial

An easy tutorial on how to make a grid based building system in Unity. You don't need to write a custom grid! The system works with standard Unity tilemaps. It implements grid snapping and placement checking. As an example, I used an isometric grid but it will work for any 2d grid.

Grid placement is a very common mechanic used in simulation games, tycoon and city builders, rpg and rts games. I developed this system when I was making my fantasy town simulation game Lost in Athilidus. In my devlogs, I share a lot of useful resources so you can learn how to make a game in Unity by yourself.
