I can not locate where the problem is coming from, I am trying to make an online game and it keeps telling me there’s an error with my public function:‘stage.addEventListener…onKeyPressed)…’ It may be something simple with the arrangements of my code but I cant work it out and the deadline is on Thursday. If somebody could help me on this matter it would be much, much appreciated!
