       Name: LL164, Removed                                          [Show more]
       Type: Subroutine
   Category: Drawing circles
    Summary: Make the hyperspace sound and draw the hyperspace tunnel
    Context: See this subroutine in context in the source code
 References: No direct references to this subroutine in this source file


 See the IRQ1 routine for details on the multi-coloured effect that's used.

\
\ LDA #56               \ Call the NOISE routine with A = 56 to make the sound
\ JSR NOISE             \ of the hyperspace drive being engaged
\
\ LDA #1                \ Set HFX to 1, which switches the screen mode to a full
\ STA HFX               \ mode 5 screen, therefore making the hyperspace rings
\                       \ multi-coloured and all zig-zaggy (see the IRQ1 routine
\                       \ for details)
\
\ LDA #4                \ Set the step size for the hyperspace rings to 4, so
\                       \ there are more sections in the rings and they are
\                       \ quite round (compared to the step size of 8 used in
\                       \ the much more polygonal launch rings)
\
\ JSR HFS2              \ Call HFS2 to draw the hyperspace tunnel rings
\
\ DEC HFX               \ Set HFX back to 0, so we switch back to the normal
\                       \ split-screen mode
\
\ RTS                   \ Return from the subroutine
