PICK SCREEN
This command will calculate a relative 3D coordinate from a 2D screen coordinate.
PICK SCREEN Screen X, Screen Y, Distance
Screen X
Integer
The x vector
Screen Y
Integer
The y vector
Distance
Float
The distance value you got from get pick distance()
This command will calculate a relative 3D coordinate from a 2D screen coordinate
The additional Distance parameter indicates how far into the screen the 3D coordinate is to be calculated. The resulting 3D coordinate is not a world position, but a relative 3D vector from the current camera position. The world coordinate can be obtained by adding the camera position to the resulting vector. The resulting vector is generated internally and can be retrieved using the GET PICK VECTOR commands.
