Flight: wW, Removed [Elite-A, Docked]

Name: wW, Removed [Show more] Type: Subroutine Category: Flight Summary: Start a hyperspace countdown
Context: See this subroutine in context in the source code References: No direct references to this subroutine in this source file

Start the hyperspace countdown (for both inter-system hyperspace and the galactic hyperdrive).
\ --- Mod: Original Acornsoft code removed: -----------> \.wW \ LDA #15 \ The hyperspace countdown starts from 15, so set A to \ \ to 15 so we can set the two hyperspace counters \ STA QQ22+1 \ Set the number in QQ22+1 to 15, which is the number \ \ that's shown on-screen during the hyperspace countdown \ STA QQ22 \ Set the number in QQ22 to 15, which is the internal \ \ counter that counts down by 1 each iteration of the \ \ main game loop, and each time it reaches zero, the \ \ on-screen counter gets decremented, and QQ22 gets set \ \ to 5, so setting QQ22 to 15 here makes the first tick \ \ of the hyperspace counter longer than subsequent ticks \ TAX \ Print the 8-bit number in X (i.e. 15) at text location \ JMP ee3 \ (0, 1), padded to 5 digits, so it appears in the top \ \ left corner of the screen, and return from the \ \ subroutine using a tail call \ --- End of removed code ----------------------------->
