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.jsoncurrentMinecraftInstanceFolder/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 externalsavesfolder. The OneWorldFolder button now opens
the normalsavesfolder of the current instance.replace_singleplayer_button(since v. 1.0.8): The single player button now
opens your specified externalsavesfolder. No extra buttons are added. If this
is enabled (set totrue), theswap_owf_and_singleplayer_buttonoption will be
ignored.
