Enemy Arm Rotation Problem, fla & swf inside

programming
1

Hello everyone,
right now I have a stick figure that walks towards the mouse cursor. I want his arm to rotate so that he points to the cursor. I have an UpperBody_mc and inside of it I have the arm that needs to rotate. I am accessing it by doing this UpperBody_mc.Arm_mc._rotation. The rotation code isn’t the problem I believe its just how I am accessing the arm or something…

heres all the code

speed = 1
onEnterFrame = function()
{
 Mx = _root._xmouse;
 My = _root._ymouse;
 CharX = (UpperBody_mc._width/2)+UpperBody_mc._x;
 if(Mx-20 < CharX && Mx+40 > CharX)
 {
  Legs_mc.stop();
 }
 else if(Mx-20 > CharX)
 {
  if(UpperBody_mc._xscale < 0)
  {
   UpperBody_mc._xscale *= -1;
   Legs_mc._x -= 5;
   Legs_mc._xscale *= -1;
  }
  UpperBody_mc._x += speed;
  Legs_mc.play();
  Legs_mc._x += speed;
  //Arm movement
 }
 else
 {
  if(UpperBody_mc._xscale > 0)
  {
   UpperBody_mc._xscale *= -1;
   Legs_mc._xscale *= -1;
   Legs_mc._x += 5;
  }
  UpperBody_mc._x -= speed;
  Legs_mc.play();
  Legs_mc._x -= speed;
 }
}
onMouseMove = function()
{
 adjside =_root._xmouse - _root.UpperBody_mc.Arm_mc._x;
 oppside = -1*(_root._ymouse - _root.UpperBody_mc.Arm_mc._y); 
 angle = Math.atan2(oppside, adjside); // in radians
 angle = Math.round(angle/Math.PI*180); // convert to degrees
 _root.UpperBody_mc.Arm_mc._rotation = -1*(angle);
}
