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.

```auto
                        
    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;

```
