Merging Default Game Options into options.txt

Setting Up Default Options

Distributing a raw options.txt file normally poses a problem because it risks overwriting a player's preferred controls or video settings. Configured Defaults solves this by handling options.txt with a smart merging feature.

1. Open the configureddefaults folder located in your main Minecraft directory.

2. Place an options.txt file inside this folder containing the default settings or specific lines you want to apply to the game.

How Smart Merging Works

When you start the game, Configured Defaults processes the file without resetting your personal choices:

1. The mod compares the options.txt inside configureddefaults with the active options.txt in your main directory.

2. Any missing lines or newly introduced settings are merged directly into your active file.

3. Existing player preferences—such as custom video options, audio levels, and keybindings—are preserved and will not be deleted or overwritten.

This allows new options to take effect while keeping player-customized settings intact.
