The landscapeOffset variable - Lander on the Acorn Archimedes

       Name: landscapeOffset                                         [Show more]
       Type: Variable
   Category: Landscape
    Summary: The offset we apply to the on-screen landscape to push it away
             from us and to the left, so the visible tiles fit nicely on-screen
    Context: See this variable in context in the source code
 References: This variable is used as follows:
             * landscapeOffsetAddr uses landscapeOffset


.landscapeOffset

 EQUD    -LANDSCAPE_X
 EQUD    LANDSCAPE_Y
 EQUD    LANDSCAPE_Z

[X]

Configuration variable LANDSCAPE_X = LANDSCAPE_X_WIDTH / 2

The x-coordinate of the landscape offset, which is set to the whole number of tiles that fit into the half the width of the landscape, so we end up looking at the middle point of the landscape

[X]

Configuration variable LANDSCAPE_Y = 0

The y-coordinate of the landscape offset, which is zero so the landscape remains at the same height

[X]

Configuration variable LANDSCAPE_Z = LANDSCAPE_Z_DEPTH + (10 * TILE_SIZE)

The z-coordinate of the landscape offset, which is set to push the landscape away from the viewer by ten tile sizes
