Config

One world folder has a config to change its behavior. The config-file currently must be edited manually.

Config Location

There are two possible locations for this config file:

  • .minecraft/config/oneworldfolder/oneworldfolder.json
  • currentMinecraftInstanceFolder/config/oneworldfolder/oneworldfolder.json

The config with the highest priority will be used.

Default Config

The generated default config looks like this:

{
    "external_saves_directory": "--auto-detect",
    "priority": -1,
    "swap_owf_and_singleplayer_button": false, 
    "replace_singleplayer_button": false, 
    "additional_resourcepacks_dirs": []
}

This config will automatically detect the default saves folder located in .minecraft.

Custom external saves folder

To use a custom saves folder set external_saves_directory to your desired directory:

{
    "external_saves_directory": "C:/Users/username/mycoolsaves",
    "priority": -1,
    "swap_owf_and_singleplayer_button": false,
    "replace_singleplayer_button": false,
    "additional_resourcepacks_dirs": []
}

Custom external resourcepacks folder (since v. 1.0.13)

To use a custom resourcepacks folder add your desired directory to additional_resourcepacks_dirs:

{
    "external_saves_directory": "C:/Users/username/mycoolsaves",
    "priority": -1,
    "swap_owf_and_singleplayer_button": false,
    "replace_singleplayer_button": false,
    "additional_resourcepacks_dirs": [
        "C:/Users/username/mycoolresourcepacks"
    ]
}

In the above example the mycoolresourcepacks folder acts exactly as the resourcepacks folder of your Minecraft
instance.

Other Config Options

  • swap_owf_and_singleplayer_button (since v. 1.0.8): The single player button now
    opens your specified external saves folder. The OneWorldFolder button now opens
    the normal saves folder of the current instance.
  • replace_singleplayer_button (since v. 1.0.8): The single player button now
    opens your specified external saves folder. No extra buttons are added. If this
    is enabled (set to true), the swap_owf_and_singleplayer_button option will be
    ignored.
