hi guys,  
here i found a glitch, here is my code as it executes the character flies in decreasing y direction, & its motion along x-axis is jerky.

* * *

var t:int=0;  
var wal:Array;  
wal=new Array();  
var man:Object;  
var newAnimstate:String=“stand”;  
var gravity:Number=.0009;  
var lastTime:int;  
createman();  
stage.addEventListener(Event.ENTER\_FRAME,gameloop);  
function createman()  
{  
man=new Object();  
man.mc=rect.man;  
man.dx=0.0;  
man.dy=0.0;  
man.jump=false;  
man.inAir=false;  
man.jumpspeed=.8;  
man.walkspeed=.6;  
man.animstate=“stand”;  
man.direction=1;  
man.moveRight=false;  
man.moveLeft=false;  
man.walkAnimation = new Array(0,1,2,3,4,5,6,7,8,9);  
man.width=53.0;  
man.height=95.3;  
man.animstep=0;  
man.scaleX=.08;  
man.scaleY=.08;  
man.x=-31.5;  
man.y=22;  
var labels:Array=man.mc.currentLabels;  
for (var i:uint = 0; i \< labels.length; i++)  
{  
var label:FrameLabel = labels\*;  
trace("frame " + label.frame + ": " + label.name);  
}

}
