Sound: EXNO3

[Elite-A, Flight]

       Name: EXNO3                                                   [Show more]
       Type: Subroutine
   Category: Sound
    Summary: Make an explosion sound

    Context: See this subroutine in context in the source code
 References: This subroutine is called as follows:
             * DEATH calls EXNO3
             * Main flight loop (Part 10 of 16) calls EXNO3
             * OOPS calls EXNO3
             * TACTICS (Part 1 of 7) calls EXNO3




 Make the sound of death in the cold, hard vacuum of space. Apparently, in
 Elite space, everyone can hear you scream.

 This routine also makes the sound of a destroyed cargo canister if we don't
 get scooping right, the sound of us colliding with another ship, and the sound
 of us being hit with depleted shields. It is not a good sound to hear.

                        \ --- Mod: Code removed for Elite-A: ------------------>

\ LDA #16               \ Call the NOISE routine with A = 16 to make the first
\ JSR NOISE             \ death sound

                        \ --- And replaced by: -------------------------------->

 JSR n_sound10          \ Call n_sound10 make the first death sound

                        \ --- End of replacement ------------------------------>

 LDA #24                \ Call the NOISE routine with A = 24 to make the second
 BNE NOISE              \ death sound and return from the subroutine using a
                        \ tail call (this BNE is effectively a JMP as A will
                        \ never be zero)
