Drawing the landscape: GetTileEdgeToRight

       Name: GetTileEdgeToRight                                      [Show more]
       Type: Subroutine
   Category: Drawing the landscape
    Summary: Move one tile to the right along the tile row that we are
             analysing for view edges and tile angles
    Context: See this subroutine in context in the source code
 References: This subroutine is called as follows:
             * GetTileViewEdges calls GetTileEdgeToRight


.GetTileEdgeToRight

 LDY xTile              \ Set Y to the column of the tile corner we are
                        \ currently analysing when looking for the view edges
                        \ and calculating the tile's pitch and yaw angles

 INY                    \ Increment Y to move one tile to the right

 CPY #32                \ If Y = 32 then we have gone past the end of the tile
 BEQ prev1              \ row and can't move any further tight, so jump to prev1
                        \ to return from the subroutine with the C flag set

                        \ Otherwise fall through into GetTileViewAngles to
                        \ analyse the new corner to look for the view edges and
                        \ calculate the tile's pitch and yaw angles, and return
                        \ from the subroutine with the C flag clear
