Description:

This plugin is intended to play one random music on each new map start (the same one music will be played on round re-start).
Only one song will be downloaded to client each map start, so it will reduce client connection delay.
In this way, you can install infinite number of music tracks on your server without sacrificing connection speed (compared to: if you would download all files at once).

Plugin will display menu to clients on each round start (can be disabled by "l4d_music_mapstart_showmenu" ConVar):
- greetings and congratulation lines (see translation file)
- 5. Stop music
- 6. Play music again
- 7. Settings

Settings menu:
- 1. Volume
- 2. Next track (in debug mode)
- 2. Don't show this menu on map start
- 3. Don't play music on next map

Commands:

sm_music - open music menu
sm_music <arg> - play specific music by id, where arg should be 0 .. to max or -1 to play next index (Use together with #DEBUG 1 mode only!)
sm_music_update - populate music list from config (use, if you replaced config file without server/plugin restart).

Settings (ConVars):

l4d_music_mapstart_enable - Enable plugin (1 - On / 0 - Off)
l4d_music_mapstart_delay (default - 17) - Delay (in sec.) between player join and playing the music
l4d_music_mapstart_showmenu - Show !music menu on round start? (1 - Yes, 0 - No)

Music preparation & Optimization & Installation & Testing

Spoiler

Preparation of MP3 files

- file names
Ensure noone file has special characters like "long dash" (–) or so.

- sample rate
All MP3 files must be encoded in 44100 Hz sample rate, otherwise it may not play at all.
To ensure, you can download MP3 Quality Modifier tool: https://www.softportal.com/get-22375...-modifier.html and re-encode all files at once.

- file size
Next, it is recommended every file will not be > 5 MB. in size (to improve download speed).
To decrease the size, sort all your files by size, send the files > 5 MB to above tool and re-encode them in 128 (or 192) Kbit/s bitrate (select "constant" mode first).

Preparation the list
Download and unpack archive from the 1st post.
Copy MP3 files to sound/valentine folder.
Run (double-click) sound/valentine/create_list.bat file.

Setup server to work with downloadable content
ConVars in your cfg/server.cfg should be:

sm_cvar sv_allowdownload "1" sm_cvar sv_downloadurl "http://your-content-server.com/game/left4dead/"

/your-content-server.com/game/left4dead/sound/valentine/ <= here is your *.mp3 files

Edit greetings and congratulations
see addons/sourcemod/translations/MusicMapStart.phrases.txt file, items:
- Congratulation1
- Congratulation2
- Congratulation3

Uploading files to server. Phase 1.
1. Upload "sound" folder to content-server
2. Upload "sound" folder to basic server.
3. Upload "sound" folder to your client's \steamapps\common\left 4 dead\left4dead\ folder (for test reasons).
4. Upload "addons" folder to basic server.

Testing the music
Edit addons\sourcemod\scripting\scripting\l4d_Musi cMapStart.sp file:

#define DEBUG 0

replace by

#define DEBUG 1

compile it, l4d_MusicMapStart.smx file copy to addons/sourcemod/plugins folder on server.

Reboot the server.
Join, wait until all sounds will be downloaded.
Wait the menu (if it is not opened, enter !music in chat)
Check that every sound is played correctly by pressing "Next track" menu item or !music -1 in chat.
Remove or fix the broken tracks, e.g.:
- check again mp3 files with MP3 Quality Modifier (see screenshot under post).
- recode tracks to increase volume, e.g. use "GoldWave" tool or Audacity (see screenshot under post). Note, that in-game volume level 1.0 can be higher than default one you listen in "GoldWave", so you need to listen recoded tracks in-game again to determine whether high / low frequencies are distorted after increasing volume amplitude.

Finalizing
Return back initial line:

#define DEBUG 0

re-compile the plugin and upload it to server.

Remove "sound/valentine" folder from your steam client's game folder.
Reboot the server.
Join and ensure sound is correctly downloaded and played on map (round) start.

Known bugs:

- sometimes "PlayAgain" button is not working. You need to press it several times.
- some default game sounds interrupt music sound on map start, so you need to set large enough value for "l4d_music_mapstart_delay" ConVar (like > 10, by default == 17) (Walkaround is unknown)

TODO:

Add cookie for saving individual client's preferences for:
- Volume level
- Show this menu on start
- Play music on start

Can U Fix it?Thx.

[Dragokas]

It is sourcemod problem, not mine.

Use: https://spider.limetech.io

[HarryPotter]

wow, it really works!!!!!!!!!!!!!!!!!!
wonderful, perfect and nice!!!!!!!!!!!!!!!!!!

I thought this would never be possible in left 4 dead 1
It makes server more fun
Thanks for your great work really

[HarryPotter]

I tested in left4dead, all fine
But when I tested in left4dead2, I found there are few different details.
1.rewrite create_list.bat

Spoiler

2>nul del "%list%"
for %%a in (*.mp3) do >> "%list%" < NUL set /p "=%p%" & >> "%list%" echo valentine/%%a

echo File list is successfully rewrited and saved to: %list%
echo.
pause

2.ConVars in your cfg/server.cfg should be:
-If you are l4d1
sm_cvar sv_allowdownload "1"
sm_cvar sv_downloadurl "http://your-content-server.com/game/left4dead/"
-If you are l4d2
sm_cvar sv_allowdownload "1"
sm_cvar sv_downloadurl "http://your-content-server.com/game/left4dead2"

3.client downloads two mp3 files once when joining the server
I believe l4d2 server calls OnMapStart() twice
so I modify below and it works

PHP Code:

public void OnPluginStart()
{
 .
 .
 .
 .
  if(g_Engine == Engine_Left4Dead)
        OnMapStart();
}

[SM] Blaming: l4d_MusicMapStart.smx

Error is clearly said you didn't put this file on the server at the specified place.

[Dragokas]

No, because:

Preparation the list Download and unpack archive from the 1st post. Copy MP3 files to sound/valentine folder. Run (double-click) sound/valentine/create_list.bat file.

music_mapstart.txt will be created automatically.
