how do I find "game variable"?

[Mxyfell]

There are some adjustments to be made to the song, namely:

    game.showCombo = false;
    game.showRating = false;
    game.showComboNum = false;

but it says:
[ 23:57:20 | ERROR ] Script.hx:15: Unknown variable: game

[Mxyfell]

added var game = PlayState.instance;, now says Script.hx:16: Invalid field:showCombo

[Mxyfell]

read PlayState.hx and found what I needed
