FlxCamera perspective projection #167
Description
I added a helper function to work with perspective projection in FlxCamera that I think could be useful.
/**
* Helper function to change the camera's perpective.
*
* @param fiedOfView Specifies an angle, as a degree between 0 and 180, for the field of view in three dimensions.
* This value determines how strong the perspective transformation and distortion apply to a three-dimensional display object with a non-zero z-coordinate.
* @param rotationX Indicates the x-axis rotation of the DisplayObject instance, in degrees, from its original orientation relative to the 3D parent container.
* Values from 0 to 180 represent clockwise rotation; values from 0 to -180 represent counterclockwise rotation.
* Values outside this range are added to or subtracted from 360 to obtain a value within the range.
* @param rotationY Indicates the y-axis rotation of the DisplayObject instance, in degrees, from its original orientation relative to the 3D parent container.
* Values from 0 to 180 represent clockwise rotation; values from 0 to -180 represent counterclockwise rotation.
* Values outside this range are added to or subtracted from 360 to obtain a value within the range.
* @param rotationZ Indicates the z-axis rotation of the DisplayObject instance, in degrees, from its original orientation relative to the 3D parent container.
* Values from 0 to 180 represent clockwise rotation; values from 0 to -180 represent counterclockwise rotation.
* Values outside this range are added to or subtracted from 360 to obtain a value within the range.
