Introduction
Summary
TobEx (Throne of Bhaal Extender) is a dynamic link library (DLL) written in C++ that fixes game engine bugs and extends the game engine by modifying the virtual image of the Throne of Bhaal BGMain.exe in memory.
TobEx is both a modification for players and a resource for modmakers. Briefly, the features of TobEx are:
- Bug fixes to a variety of different parts of the engine
- More debugging information
- Extensions to the user interface, such as additional scrollbars
- Optional tweaks to engine behaviour
- (Modders) Externalisation of hard-coded behaviour
- (Modders) New and modified triggers, actions, and effects
Contents
This redistributable package contains the core TobEx files available for modders to use within their modifications. The source code for the program is included with compile notes in the ./TobEx/src directory. The revision history is located in revisions.txt

Requirements
TobEx requires Baldur's Gate II: Throne of Bhaal version 26498. The modification will not work on other versions of Throne of Bhaal.
TobEx is programmed and primarily tested on Windows sytems. It may work on Linux systems, and is unlikely to work on Macintosh systems.

Usage
Including TobEx in your modification
You are free to include this redistributable package in your modifications. Please give credit where it is due.
In order to install TobEx as part of your modification:
- Place the entire ./TobEx_redist directory within your mod directory.
- Insert the following code into your mod's main .tp2 file. Replace <your mod directory> with the directory that your mod uses. Please note that TOBEX_ is used as a prefix to make the variable unique. It should not point to the TobEx mod directory, but to your mod's directory.
OUTER_SPRINT TOBEX_MOD_DIRECTORY "./<your mod directory>"
LOAD_TRA "%TOBEX_MOD_DIRECTORY%/TobEx_redist/TobEx.tra"
ACTION_INCLUDE "%TOBEX_MOD_DIRECTORY%/TobEx_redist/TobEx.tpa"
- Once installed, existing tweak settings are kept and all new tweak settings are disabled by default. In order to activate tweaks, use REPLACE_TEXTUALLY on TobEx_ini/TobExTweak.ini. For example:
COPY "TobEx_ini/TobExTweak.ini" "TobEx_ini/TobExTweak.ini"
REPLACE_TEXTUALLY "A Tweak=0" "A Tweak=1"
BUT_ONLY_IF_IT_CHANGES
- In order to support translations to other languages, translators should translate TobEx.tra. Then, modify the LOAD_TRA tp2 action to point to the language-specific .tra file. For example:
LOAD_TRA "%TOBEX_MOD_DIRECTORY%/language/%LANGUAGE%/TobEx.tra"
Notes
- If another mod has installed TobEx_redist, the installation will check the user's current TobEx_redist version and update accordingly if required. There is no need to manually check the user's current TobEx_redist version.
- Core tweak settings are not kept. If your mod installs a new version of TobEx_redist, the existing settings in TobEx_ini/TobExCore.ini are overwritten.
- Existing tweak settings are kept. If your mod installs a new version of TobEx_redist, the existing settings in TobEx_ini/TobExTweak.ini are kept.
- There is no need to, although you can, install TobEx_redist as a separate component in your modification. If required, check for the presence of an existing TobEx_redist version by using FILE_EXISTS "TobEx_ini/TobExVer.txt".
- TobEx translation strings occupy references starting from @-10000 and going lower (more negative). Avoid using these strings in your modification because TobEx will overwrite them.
- In order to load TobEx.dll on game startup, the following BGMain.exe executable addresses are used:
0x639573-0x63957C
0x66F0F5-0x66F0FB
0x66F115-0x66F11C
0x66F135-0x66F13E
Upgrading
- Remove the entire existing ./TobEx_redist directory within your mod directory.
- Place the entire new ./TobEx_redist directory within your mod directory.

Troubleshooting
First, make sure that TobEx is actually the issue. You can forcefully disable TobEx from running by renaming TobEx.dll in your game directory.
For more debugging information:
- Open TobEx_ini/TobExCore.ini in a simple text editor.
- Under the [Debug] section, set all values of 0 to 1.
- Try to reproduce your error in-game. TobEx may sometimes reports some extra information about the error.
- Report any errors you find on the Spellhold Studios forums. Expect to be asked to attach a .zip of your saved game folder, WeiDU.log, TobEx.log, TobExCore.ini, and TobExTweak.ini.
