Anchor. Anchor will choose a location on the screen to “anchor” the Viewport, and further offsets and adjustments can be made from that location. The options available are TopLeft, Top, TopRight, Left, Center, Right, BottomLeft, Bottom, and BottomRight; all corresponding to a location in the Player.
Offset (X, Y). The Offset properties allow the Viewport to be offset from their anchored location. The A and R buttons indicated absolute vs. relative measurement. If set to A, the offset is a pixel value. If set to R, the offset is relative to the size of the viewport (i.e. an Offset Y value of 0.5 will offset it by half of the viewport’s height).
Height and Width. These properties dictate the measurements of the viewport. Similar to the Offsets, they can be modified in either absolute or relative measurements using the A and R buttons.
Note that when you create a viewport, it will display a blank screen by default – this is because there is no Camera assigned to it. For instructions on how to connect a Camera to a Viewport, see the Cameras documentation.
Connecting a Viewport to a Camera
To assign a Viewport to a Camera, open the Properties tab of the Camera. Drag the Viewport from the Scene tab to the Viewport Name box in the Properties tab of the Camera. This will display the camera’s view in the Viewport.
