var ticksFlight = 0;
    module.on("motion", function(e){
        var player = mc.thePlayer;
        if(player.posY == player.prevPosY){
            ticksFlight++;
            if(ticksFlight > 120 && ticksFlight % 20 == 0){
                Chat.print("§9§lVerus §r§8> §r" + player.getDisplayName().getUnformattedText() + " §7failed §rFly §7VL[§9" + ticksFlight + "§7]");
            }
        }else{
            ticksFlight = 0;
        }
    });
