A mod that adds a setting to control what static background you have.
To add new backgrounds you need to create a mod.
The mod has to have this mod as an dependency.
You need a settings.lua file.
To create a new background use this syntax(in settings.lua):
z.backgrounds["my-background-name"] = "my-mod/my-backgroud.jpg"
To make the background's name a little prettier make a locale/en/locale.cfg file.
In the file the syntax looks like:
[string-mod-setting]
z-background-"my-background-path"="my background's name"
thats it.
