Oni (folder)/GameDataFolder

GameDataFolder (commonly called "GDF") is a subfolder of the main Oni folder. It holds the following:

• Oni's game data (see OBD for more info)
• the level logic (as scripts in the IGMD subfolder; see BSL for more info)
• the intro and outro animated sequences, in the Bink video format

Overview

You should have all the files in bold in your GameDataFolder, but the movie files are optional. The "PS2" column shows the numbers assigned to each file name on disc; the .raw and .sep file for each level are in subdirectories titled 20/ and 21/. Beside each set of level files, we list the subfolders of IGMD which hold the corresponding level logic. SPOILER WARNING: The "Chapter" column links to summaries and analyses of Oni's storyline.

Notes

level0_Final

The level 0 data is only loaded once, when Oni starts.

IGMD/global

IGMD/global/ is not present by default, but if it is created, the functions in any scripts placed inside it will be accessible from all levels; however, the Windows demo engine ignores the global/ folder.

Movie files

Epic Games Tools, the makers of the Bink video format, offer standalone apps for all platforms if you want to watch the .bik files on their own. The movie files are not needed for Oni to run. You can thus rename or move intro.bik out of GameDataFolder so Oni starts faster.

How Oni finds its GameDataFolder

In Windows, Oni's engine first looks up GDF in the working directory (a.k.a. "."). If ".\GameDataFolder" is missing, Oni tries parent folders all the way up to the root (e.g., it looks for "C:\Program Files\Oni\GameDataFolder", then "C:\Program Files\GameDataFolder", then "C:\GameDataFolder"). As a last resort, it looks for ".\OniEngine\GameDataFolder" the same way.

The Mac Oni app follows the same search pattern for GameDataFolder/, but does not look for OniEngine/GameDataFolder/.
