The FixedToCamera component enables a Game Object to be rendered relative to the game camera coordinates, regardless
of where in the world the camera is. This is used for things like sticking game UI to the camera that scrolls as it moves around the world.
The x/y coordinate offset applied to the top-left of the camera that this Game Object will be drawn at if
fixedToCamera is true.
The values are relative to the top-left of the camera view and in addition to any parent of the Game Object on the display list.
A Game Object that is "fixed" to the camera uses its x/y coordinates as offsets from the top left of the camera during rendering.
The values are adjusted at the rendering stage, overriding the Game Objects actual world position.
The end result is that the Game Object will appear to be 'fixed' to the camera, regardless of where in the game world
the camera is viewing. This is useful if for example this Game Object is a UI item that you wish to be visible at all times
regardless where in the world the camera is.
The offsets are stored in the
Note that the
cameraOffset values are in addition to any parent of this Game Object on the display list.
Be careful not to set
fixedToCamera on Game Objects which are in Groups that already have
fixedToCamera enabled on them.
