📋 About This Mod
This mod adds a few functions which can be used in GECK scripting, and provides game patches to fix engine bugs.
These are mostly ported from JazzIsParis' JIP LN NVSE plugin.
Bugfixes
-
[]Gaining XP above level 99 no longer crashes the game.[/]
[]Equip sound no longer plays if item is already equipped.[/]
[]Console functions fully with a controller connected.[/]
[]Disabling controller vibration, either via the Settings Menu, or by setting bGamePadRumble=0 in FalloutPrefs.ini, does what it was supposed to do - completely disable any motor vibrations (this should significantly prolong the life of your batteries).[/]
[]Fix dead actors T-posing when loading[/]
[]Fix lag when the target HP bar updates. Particularly noticeable with uncapped framerate or high fire-rate weapons.[/]
[]Total player DR updates when a vendor repairs a worn item. [/]
[]Fix player placed marker not working properly in modded child worldspaces.[/]
Extra features:
-
[]FalloutCustom.ini may now be created in the game's user folder (%USERPROFILE%\Documents\My Games\Fallout3). Setting entries included in this file will overwrite the values defined in either Fallout.ini or FalloutPrefs.ini. This allows modifying the game's configuration files without actually editing them. This also ensures any INI tweaks will persist and will not be reset/discarded by a mod organizer or the default launcher.[/]
[]Search command may be used in console to find formIDs.[/]
[]Runtime Editor IDs: GECK Editor IDs can now be used in game console (e.g. "player.additem weap10mmpistol") and in scripts using the EditorIDToFormID function. Additionally, Editor IDs are now displayed when you select a reference without a name in game console.[/]
[]CenterOnCell (coc) command now accepts formIDs.[/]
Requirements
Game version 1. 7. 0. 3 - if you're using Steam you will need to run the Anniversary Patcher.

Installation
Use Mod Organizer 2/Nexus Mod Manager/FOMM, or manually extract the .zip file into your Fallout 3 'Data' folder.
The final path will be Fallout 3 goty/Data/FOSE/Plugins/CommandExtender.dll
