I'm almost done making the game but I have little experience with coding and the issue I am facing right is whenever I hover over a taken spot on the matrix with the joystick, the LED turns off. So I want add a condition that will make the LED skip over occupied areas. I have an idea of maybe using an array but I have no clue how to actually do it using the Adafruit library. I think adding the win condition of the game should use the same idea but I'll leave that after solving this problem. Any help is very appreciated!
Edit: I updated the code and now player1 can go over its own LED (Green) and p2 can go over its own LED (Red) with no problems. But How do I make them skip over occupied areas?
Shown below is the program, libraries, and the parts that I used. I also have some comments that could help.
