ProjectedX:Float32

Returns: The X position in pixels.

Description

Gives the horizontal screen position of the point that the last CameraProject looked at, in pixels from the left edge of the screen.

Differences

• The original returns 0 for X, Y and Z when the point is behind the camera or beyond the far plane. Here X and Y are -1000000 for a point behind the camera, so that it is obviously off the screen.
