You can use TextDrawShowForAll() in OnGameModeInit(), but that's not useful, because that means it would show the textdraw for all online players in THAT moment (probably none). You need to add TextDrawShowForPlayer in OnPlayerConnect.

EDIT: Lol, that coordinates are outside the screen. (Textdraw1 = TextDrawCreate(476 ,451 , "Textdraw String")
