Hi, I just started using unity 3 days ago, and I am planning to make a 2d tile-based and chess-like game. I have watched a lot of tutorials and made my character move on the board, but I found when I hit the play button, the grid cells of my tilemap do not appear in the game window. Do I have to implement my own grid system for the board? If I made that kind of system, how can I get access to each cell?
yes you need to add your own graphics for a visual grid.
You still keep the grid component for the code side.
It seems like you’re using a Tilemap for your board. Why don’t you take a look at these tutorials to start. They explain tile maps but you’ll get a lot of information about other topics also.
