If you're wondering how to get a different background-wallpaper (and/or background map) for (almost) each game start. Like in HL2 game.
Cvar
The game has a cvar that remembers where you left off the last chapter.
"sv_unlockedchapters" = "1" archive - Highest unlocked game chapter.This cvar will not change in any phase of the (Cs:s) game.
Chapters
"chapters"
{
"1" "background01"
"2" "background02"
"3" "background03"
"4" "byanyothername"
}
The first parameter is the chapter number. The second parameter is the name of the background.
Background texture
The game is loading the background texture from here, ...cstrike/materials/console/
"UnlitGeneric"
{
// Original shader: BaseTimesVertexColorAlphaBlendNoOverbright
// Uncomment this if you add an alpha channel to the base texture
// "$translucent" 1
"$basetexture" "dev/dev_signflammable01a" // Example
"$vertexcolor" 1
"$no_fullbright" 1
"$ignorez" 1
}
This far, different background images should be in action.
Background maps
// load the base configuration //exec default.cfg r_decal_cullsize 1 // Setup custom controller exec joystick.cfg // run a user script file if present exec autoexec.cfg // // stuff command line statements // stuffcmds // display the startup level startupmenu
There are a few things that prevent the background maps working.
Finally, what I have already mentioned a moment ago. You need the background maps that is named after the "chapters". The maps must be located at this path ...cstrike/maps/ example maps to above "chapters" background01.bsp background02.bsp background03.bsp byanyothername.bsp
