Game update script

This documents the script update_gi.sh. The other scripts have a short explanation in their file content.

Description

This script automates following steps:

1. Check for game updates
2. Download the game files
3. Revert any previously applied patches
4. Install or update the game files
5. Apply the newest patch

If you prefer a graphical updater, check out:

• Paimon Launcher
• An Anime Game Launcher

Requirements

This script requires following applications:

• bash (update and patch script)
• jq (JSON parsing)
• Either aria2c, wget, curl or axel (file download)
• xdelta3 (patch script)

Usage instructions

The current working directory (pwd) specifies the update or installation path.

Example + syntax:

cd "/path/to/game/directory/"
bash "/path/to/dawn/updater/update_gi.sh" [OPTIONS ...]

List of OPTIONS:

• --help: Shows a short help text
• install: Switches from the "update" to "installation" mode
  • By default, an update will be performed in the current directory
• nodelete: Keeps the downloaded archives after the installation or update.
• predownload: Checks and downloads pre-download-game archives
  • To perform the update afterwards, re-run the update script without the predownload option.

If errors occur after updating the game files, re-run the patch scripts manually.

New installation

Use the install command line option to install the newest game version to an empty directory.

Example:

# Create a new directory in HOME (~) for the installation
mkdir -p "$HOME/Genshin Impact Game"
cd "$HOME/Genshin Impact Game/"

bash "/path/to/dawn/updater/update_gi.sh" install

Game update

Updates the game in the working directory to the newest version.

Important: If the official launcher was used for the installation, ensure that the current working directory (pwd) contains GenshinImpact.exe but not launcher.exe.

Example:

# Update game located in HOME
cd "$HOME/Genshin Impact Game/"
bash "/path/to/dawn/updater/update_gi.sh"

For advanced users: perform_update.sh can be used to manually apply downloaded archives
