but i am getting this errors

i am beginder trying the best i can to make my game, i am thankful for eny help

You have this function

function menuSelection (menuItems, selectedItem, direction) {

. Like you have it now you don’t declare their type so they default to the Object Type. What you have to do is change the part in brackets to something like this:

function menuSelection (menuItems : String[], selectedItem : int, direction : String) {

Maybe you have to change it a bit when you if you need slightly different types.
