Screen buffer: SetColumnBufferMax

       Name: SetColumnBufferMax                                      [Show more]
       Type: Subroutine
   Category: Screen buffer
    Summary: Set the maximum and minimum pitch angles for the column buffer
    Context: See this subroutine in context in the source code
 References: This subroutine is called as follows:
             * PanLandscapeView calls SetColumnBufferMax
             * ResetTilesObjects calls SetColumnBufferMax


.SetColumnBufferMax

 LDY #1                 \ Set Y = 1 so we set the maximum and minimum pitch
                        \ angles for the column buffer when we jump to rbuf1

 BNE rbuf1              \ Jump to rbuf1 to set the maximum and minimum pitch
                        \ angles for the column buffer and return from the
                        \ subroutine using a tail call (this BNE is effectively
                        \ a JMP as Y is never zero)
