it says all compiler errors have to be fixed. help me and what does that mean???
That you have scripts with errors. You can't run the game until all scripts you have in your project compile correctly. The console should show which scripts have what errors.
Bottom left hand corner, click the red part, it'll open up the "Log" or open this up through the top toolbar, and it'll show you your errors in your scripts/game.
Good luck and have a good new year!
