rotating-problem of enemy

[drpelz]

Hello folks,

I have this problem: there is this enemy which rotates to my player. While "orbiting" the enemy with my player I can see that the enemy is rotating towards my player.
And then the enemy suddenly turns around 360 degrees and facing to my player again. I don't know why it does this strange 360 degree turn but it happens everytime when I orbit the enemy for a few seconds. Please - can someone help me out with this problem? I appreciate every hint I can get because I don't know where the problem might be.

						
	tempEnemy.dX = tempEnemy.x - player.x;
	tempEnemy.dY = tempEnemy.y - player.y;
							
	tempEnemy.rotateTo = toDegrees(getRadians(tempEnemy.dX, tempEnemy.dY));
							
							
							
	if(tempEnemy.frame < 0) tempEnemy.frame += 360;
	if(tempEnemy.frame > 359) tempEnemy.frame -= 360;
							
							
	tempEnemy.trueRotation = int((tempEnemy.rotateTo - tempEnemy.frame) / tempEnemy.rotateSpeed);
							
	tempEnemy.vX += (player.x - tempEnemy.x) / tempEnemy._speed;
	tempEnemy.vY += (player.y - tempEnemy.y) / tempEnemy._speed;
			 
	tempEnemy.vX *= tempEnemy.decay;
	tempEnemy.vY *= tempEnemy.decay;

Update:

private function toDegrees(radians:Number):Number
    {
        var degrees:Number = Math.floor(radians * 180 / Math.PI);
        //trace (degrees);
        return degrees;
    }

private function getRadians(deltaX:Number, deltaY:Number):Number
    {
        var radian:Number = Math.atan2(deltaY, deltaX);

        if (deltaY < 0)
        {
            radian += (2 * Math.PI);
        }
        return(radian);
    }
