after i built the game , when i tried to edit more to add in more objects i got this . “All compiler errors must be fixed before entering game mode.” there was nothing wrong with my code. so i deleted my player controller script from the player and when i tried to add it back in , it rejected my code , so i really don’t know whats happening.
I had the issue with “All compiler errors must be fixed before entering game mode” also. The way I fixed it was by just saving my scene, closing unity, and the opening it up again. After that, when I pressed play, the game ran fine. Hope you get it fixed
