# Greetings, fellow Penguin!

# This script is designed to help you manage and optimize
# Star Citizen on Linux.
2020-08-02 18:12:02 +00:00

2021-01-03 18:48:48 +00:00
# - It presents options to check your system for optimal settings
# and helps you change them as needed to prevent game crashes.
2020-08-02 18:12:02 +00:00
#
2021-01-03 18:48:48 +00:00
# - It gives you an easy way to manage your Lutris wine runners.
#
# - It can quickly wipe your Star Citizen USER folder as is recommended
# by CIG after major version updates.
# It will back up your exported keybinds, delete your USER folder,
# then restore your keybind file(s).
#
# - It supports both the LIVE and PTU environments
#
# - Zenity menus are used for a GUI experience with a fallback to
# terminal-based menus where Zenity is unavailable.
2020-08-02 18:12:02 +00:00

# To export your keybinds from within the game, go to
# Options->Keybindings->Control Profiles->Save Control Settings
#
2020-08-22 01:24:26 +00:00
# To import your keybinds from within the game, select them from the list:

#
# Requires two arrays to be set: "menu_options" and "menu_actions"
# two string variables: "menu_text_zenity" and "menu_text_terminal"
2020-09-07 22:51:19 +00:00
# and one integer variable: "menu_height".
#
# - The array "menu_options" should contain the strings of each option.
# - The array "menu_actions" should contain function names to be called.
# - The strings "menu_text_zenity" and "menu_text_terminal" should contain
# the menu description formatted for zenity and the terminal, respectively.
# This text will be displayed above the menu options.
# Zenity supports Pango Markup for text formatting.
# - The integer "menu_height" specifies the height of the zenity menu.
2020-09-07 22:51:19 +00:00
#
# The final element in each array is expected to be a quit option.
#
# IMPORTANT: The indices of the elements in "menu_actions"
# *MUST* correspond to the indeces in "menu_options".
# In other words, it is expected that menu_actions[1] is the correct action
# to be executed when menu_options[1] is selected, and so on for each element.
