    Facing a waypoint

    Greetings,

    I've been trying for days to figure out how to calculate where I need to turn in order to face my waypoint. I am aware that there's been several threads created asking for this - in which solutions has been posted. However, nothing is giving me equitable results.

    So the question is: How do I calculate what my player rotation has to be (out of PI*2) in order to face my waypoint which is at: X:55.24, Y:66.89

    I get my player rotation from the wow API - GetPlayerFacing(). The coordinates I'm working with are formatted as such:
    55.71, 67.51

    This is one of the functions I've tried (Which has returned utterly wrong angles) It's however returning something... But I found no pattern in the results:

    C#

    Code:
            private void button1_Click(object sender, EventArgs e)
            {
                MessageBox.Show(GetFacingAngle().ToString());
            }
    
            public static float GetFacingAngle()
            {
                float angle = (float)Math.Atan2(target_y - player_y, target_x - player_x);
    
                if (angle < 0.0f)
                {
                    angle = angle + (float)Math.PI * 2.0f;
                }
                else if (angle > (float)Math.PI * 2)
                {
                    angle = angle - (float)Math.PI * 2.0f;
                }
                return angle;
            }
    What am I doing wrong?

    Works for me.

    Code:
    var delta = target.Position - player.Position;
    var angle = Math.Atan2(delta.Y, delta.X);
    angle += Math.PI * 2;
    angle %= Math.PI * 2;

    It really does not want to work for me. I for example get 3.45678 when it should return 5.16789. The results are always inconsistent.

    -Edit-

    With this placement of coordinates, it works.
    I'll leave the solution here:

    Code:
    var target_x = Navigation.loadedXcoord;
    var player_x = Navigation.myCoordinates.x;
    var target_y = Navigation.loadedYcoord;
    var player_y = Navigation.myCoordinates.y;
    
    var atan2X = (player_x - target_x);
    var atan2Y = (player_y - target_y);
    
    double angle = (float)Math.Atan2(atan2X, atan2Y);
    
    angle += Math.PI * 2;
    angle %= Math.PI * 2;
    
    return (float)angle;
    Thank you Jadd, for pushing me in the right direction.
