syslog calculate facility and severity from PRI(priority)
example:
PRI = 191
To get the Facility
Divide the PRI number by 8.
191/8 = 23.875
The whole number part is the facility.
To get the Severity

Created July 17, 2012 06:47
xna move play to mouse direction
// The spritebatch has a draw method that takes in a rotation angle, you can see the overloads for draw here.
//First, you would want to get the mouse's location and store it as a vector;
MouseState curMouse = Mouse.GetState();
Vector2 mouseLoc = new Vector2(curMouse.X, curMouse.Y);
// Next, subtract the mouse's position from the sprite's position to get the direction (as a vector) that the sprite should face and convert it to a angle measured in radians;
Vector2 direction = (sprite's position) - mouseLoc;
float angle = (float)(Math.Atan2(direction.Y, direction.X));
