what is in XNA in 2D the standard way vector angles work ? 0 degrees points right, 90 points up, 180 left, 270 down ? What are the 'standard' implementations of float VectortoAngle(Vector2 vec) and Vector2 AngleToVector(float angle) so that VectortoAngle(AngleToVector(PI)) == PI ? To answer your first question, 0 degrees points up, 90 degrees points right, 180 degrees points down, and 270 degrees points left. Here is a simple 2D XNA rotation tutorial to give you more information. As for converting vectors to angles and back, I found a couple good implementations here : Vector2 AngleToVector

I am using my android phone as Access Point. Now I want to find the distance and direction of the wifi devices connected with my phone. Please help me through suitable example and code. Thanks in advance. I downloaded Wifi Radar that you mentioned and tried it. There's an important step there - it asks you to rotate on the spot for a bit while holding the device to your body. So my guess is that it uses the internal compass to figure out which direction you're pointing to, and then measures the signal. When the signal gets stronger, it figures that you're pointing toward the AP. Since the app

is it possible to get the mouse direction (Left, Right, Up, Down) based on mouse last position and current position? I have written the code to calculate the angle between two vectors but I am not sure if it is right. Can someone please point me to the right direction? public enum Direction { Left = 0, Right = 1, Down = 2, Up = 3 } private int lastX; private int lastY; private Direction direction; private void Form1_MouseDown(object sender, MouseEventArgs e) { lastX = e.X; lastY = e.Y; } private void Form1_MouseMove(object sender, MouseEventArgs e) { double angle = GetAngleBetweenVectors(lastX

In my iPhone application, I'm using using CLLocationManager to find the direction in which my iphone is pointing to. I'm using the property "heading". Its giving me x,y and z values. How can I find from these values in which direction (north or south or east or west) I'm currently pointing to? heading is a CLHeading object. As one look in the documentation would have told you, it also has properties for the true and magnetic headings in degrees. zhangcy you should use method [locationManager startUpdateHeading] to enable get the angle relative to the geographic North Pole or magnetic North
