+	/* 	Lua: Allow this hook to overwrite ticcmd.
+		We check if we're actually in a level because for some reason this Hook would run in menus and on the titlescreen otherwise.
+		Be aware that within this hook, nothing but this player's cmd can be edited (otherwise we'd run in some pretty bad synching problems since this is clientsided, or something)
+
+		Possible usages for this are:
+			-Forcing the player to perform an action, which could otherwise require terrible, terrible hacking to replicate.
+			-Preventing the player to perform an action, which would ALSO require some weirdo hacks.
+			-Making some galaxy brain autopilot Lua if you're a masochist
+			-Making a Mario Kart 8 Deluxe tier baby mode that steers you away from walls and whatnot. You know what, do what you want!
