Preferences file

The Preferences file (options.ini) contains settings to customize EmptyEpsilon. Many of these settings are set and saved within the game, while others are set only within the file. Many settings are written to the file after the first time EmptyEpsilon is launched and quit.

Unless otherwise noted, settings with on/off values use 1 to represent enabled and 0 to represent disabled.

Keyboard settings

Hotkey options are formatted like this:

HOTKEY.ENGINEERING.DECREASE_COOLANT=Left

• All available hotkey options begin with HOTKEY with default values, or no value if there is no default keybinding.
• In the above example, ENGINEERING represents the category.
• The function that the hotkey affects follows.
• The key value, if any, is last. For possible hotkey values, see the SFML documentation.

All hotkey options are written when EmptyEpsilon is closed.

Graphical settings

• disable_shaders: Disable postprocessing shaders, such as jump, wormhole, and warp glitch effects. A value of 1 disables the shaders. The default value depends on the platform.
• fsaa: Enable full-screen anti-aliasing. A value of 2 or more represents the multiplier in use.
• fullscreen: Enable fullscreen mode. If disabled, run in windowed mode.
• ship_window_flags: Values for ship_window_flags are spacedust (1), headings (2), callsigns (4). Sum them to set more than one value. Example: ship_window_caption=7 enables all three.
