The CD player¶

The CD player (cd_player, 0x00437FC0) is the screen Use CD player opens in the Reliant's rooms and the Yamato's (The Reliant's rooms). It runs in a loop of its own on a screen 640 by 480, over a picture of the player, and plays the game's music from a list of twelve pieces, each carrier its own. Its code lies within C:\lancer\game\interface.cpp.

In OpenReliant¶

game/interface/cd_player.zig holds the CD player, and the driver runs its loop (Driver.listen in openreliant/rooms.zig).

Fixes:

• Every piece comes from the list shown. The game takes the Yamato's list for PLAY SELECTED TRACK alone, and the Reliant's for the rows, the next and the previous track and the piece that follows one's end, so that on the Yamato these play the Reliant's piece in the row.
• The CD player's volume is the level its music plays at, which the music volume and the master volume scale as they scale any music (Sound). The game plays each piece at the full level and sets the stream to the CD player's volume itself, past the two volumes, so that at the music volume's default a press of either button makes the music louder.

Improvement: RANDOM TRACK MODE draws the next piece from std.Random, among the eleven others. The game draws rand() % 12 up to 20 times for one other than the piece that ended, and plays that piece again where none is.

The screen¶

As it opens, the CD player shows its picture behind the screen, interface\rel_bunk2cd.tga on the Reliant, up to mission 18, and interface\brd2cd.tga on the Yamato, after it, and reads cdplay.spr, its shapes, and the ITAC's large font, inter\itac\itacbig.fnt. Nothing is chosen, nothing is paused and the modes are off, whatever music plays already. Its drawing (cd_player_draw, 0x00438890) draws, in order:

1. The button under the pointer, lit, but for REPEAT TRACK MODE and RANDOM TRACK MODE, which are lit while they are on.
2. The title, CD PLAYER (0x3B4), at (117, 129) from its left, in the ITAC's large font, in 0x0079FE.
3. The list, a row every 16 from 171 down: its number, %02d from 01, at 117, and the piece's name at 137, in the front end's small font, in 0x0079FE, and the piece chosen in white.
4. The name of the button under the pointer, centred at (320, 440), in white, in the front end's large font.
5. The pointer, shape 12 of cdplay.spr, in the palette of the set's block 11. The buttons are drawn in block 0's.

The pointer finds a button inside its rectangle, the edges left out (interface_hit):

After the buttons come the list's rows, 400 by 14 from (117, 176), each 16 below the last.

The lists¶

Each piece plays from music\ and the name of its file, with .wav:

Playing¶

A press of the left button over a button or a row plays sound 8 of the rooms' wlksmp.fat at full volume, and does what it does on the pass the button goes down (0x0051DB40). A row chooses its piece (0x0051D9D0), and the piece chosen plays as its row is clicked again. A piece plays at once (music_play), over and over in REPEAT TRACK MODE and else once, and closes the music playing.

PLAY SELECTED TRACK and a row clicked again start the player playing (0x0051D7AC), and STOP THE CURRENT TRACK stops it. While it plays, with REPEAT TRACK MODE off and the music not paused, a piece's end is followed by the list's next piece, or in RANDOM TRACK MODE by another at random (0x00438735 on); the list's last piece is its end. The next and the previous track play without starting the player, and take the pause off, as PLAY SELECTED TRACK does; a row clicked again leaves it.

The volume (0x004E5B88), from 0 to 127, is full as the game starts and lasts while it runs. Its buttons turn it a step each pass the left button is held over them.

Escape closes the player. The music plays on in the rooms, as any music plays, without the rooms' reverb (Sound), until the briefing, the news report, the ITAC or the simulator pod fades it out (The loop).
