Please note: OBSE 0019 has been updated to 0019b. Please upgrade to the latest version.

Continuing from the http://www.gamesas.com/index.php?/topic/1131224-relz-oblivion-script-extender-obse-0019/.

The Oblivion Script Extender, or OBSE for short, is a modder's resource that expands the scripting capabilities of Oblivion. It doesn't make any modifications to oblivion.exe, TESConstructionSet.exe, or any other files in your oblivion install, so don't worry about permanent side effects.

Oblivion Script Extender v0019

The Oblivion Script Extender, or OBSE for short, is a modder's resource that expands the scripting capabilities of Oblivion. It doesn't make any modifications to oblivion.exe, TESConstructionSet.exe, or any other files in your oblivion install, so don't worry about permanent side effects. It is compatible with the 1.2.0.416 Oblivion patch, as well as the 1.2 version of the Construction Set. Versions of Oblivion downloaded via Steam are supported as well.

[ Installation ]

If you are using a retail (non-Steam) version of the game:

1. Copy obse_1_2_416.dll, obse_editor_1_2.dll, and obse_loader.exe to your Oblivion directory. This is usually in your Program Files folder, and should contain files called "Oblivion.exe" and "OblivionLauncher.exe".
2. Run oblivion by running obse_loader.exe from the Oblivion directory.

If you use a desktop shortcut to launch Oblivion normally, just update the shortcut to point to obse_loader.exe instead of oblivion.exe.

If you are using the Steam version of the game:

1. Copy obse_1_2_416.dll, obse_editor_1_2.dll, and obse_steam_loader.dll to your Oblivion directory. This is usually "C:\Program Files\Valve\Steam\SteamApps\common\oblivion".
2. OBSE will automatically be run along with Oblivion when launched. To disable this, rename or move obse_steam_loader.dll. You do not need to use obse_loader.exe unless you are running the editor.

Scripts written with these new commands must be written via the TESConstructionSet launched with obse_loader. Open a command prompt window, navigate to your oblivion install folder, and type "obse_loader -editor". The normal editor can open plugins with these extended scripts fine, it just can't recompile them and will give errors if you try.

To clarify: users of TheNiceOne's Display Stats and/or Quest Log Manager should be aware that the current versions of those mods have an issue with the way they initialize array variables. This is not at all TNO's fault - the OBSE docs fail to mention that arrays and string variables created at the game's main menu screen become invalid (by necessity) once a new game is started or a saved game is loaded. He has graciously agreed to release updates to those two mods shortly to address this issue. Users of those mods should update as soon as that happens; for the time being they will probably want to remove those mods from their load orders.

Sweet, an update.

I take it the OBSEArrayInterface::GetElement was fixed too?

I'm getting an unresolved external error when compiling MenuQue with the latest source.

1>    Creating library D:\Oblivion\src\obse_kyoma_menuque\Release\OBSE_Kyoma_MenuQue.lib and object D:\Oblivion\src\obse_kyoma_menuque\Release\OBSE_Kyoma_MenuQue.exp1>GameExtraData.obj : error LNK2001: unresolved external symbol "void __cdecl SetRetainExtraOwnership(bool)" (?SetRetainExtraOwnership@@YAX_N@Z)1>D:\Oblivion\src\obse_kyoma_menuque\Release\OBSE_Kyoma_MenuQue.dll : fatal error LNK1120: 1 unresolved externals

[edit]
Adding Hooks_Gameplay.h and Hooks_Gameplay.cpp to the project seems to fix the error but then I get dozens of other errors. And adding all the OBSE files to my project seems overkill to me....

He has graciously agreed to release updates to those two mods shortly to address this issue. Users of those mods should update as soon as that happens; for the time being they will probably want to remove those mods from their load orders.

Could you clarify this please? Oblivion XP makes extensive use of arrays and strings and has been working for years. Do I have to do anything to make it work with OBSE 19+? I'm not quite sure what you mean by "arrays and string variables created at the game's main menu screen".

Oblivion XP only requires OBSE 18. I did do some testing with the beta versions of OBSE 19, but I'm running OBSE 18 right now because I'm working on another mod that only requires 18. Ob XP worked with the beta versions of 19.

Posted: **Wed Sep 01, 2010 5:31 pm**

Could you clarify this please?

Here is a quest script which illustrates the problem:

scriptName someQuestSCRarray_var anArraystring_var aStringbegin menumode  ; this block will run at the game's title screen, before the user chooses to load a game or start a new one  let anArray := ar_construct Array  let aString := "some string"endbegin gamemode  ; this will run once the player loads a game or starts a new one  let anArray[0] := "something"  let aString += " some more stuff"end

The game starts, and the main menu is visible. Quest scripts start running. The array and string variables in the script get initialized with some ID, probably ID #1.
The user loads a saved game. All arrays and strings in memory are destroyed to make room for arrays and strings stored in his saved game. But the quest variables still contain the IDs they were previously assigned.
Now a couple of things can happen when the quest script's gamemode block runs:

1. The array or string ID stored in each variable no longer is valid, and an error about an uninitialized string or array shows up in the console and obse.log.
2. (more likely) Some other script created string and array variables after or during game load, which were assigned the same IDs as those created by the quest script at the main menu. The assignments in the quest script's gamemode block will alter an array and string which actually belong to a different script -> mayhem ensues.

#2 is what happened with QLM and Display Stats.

There's really no good way around this because we cannot know before the user loads a saved game whether or not any array or string IDs assigned during main menu will conflict with IDs stored in a saved game. As of 0019b you can sort of get away with doing it if the user starts a new game, but it's not recommended.

Nutshell: don't create arrays and string during the main menu and expect them to remain valid after the player starts a new game or loads a saved game. That has AFAICT never worked and it just happens that TNO, being unaware of this, brought it to my attention. If Oblivion XP doesn't do this (and I can't see how it could and still work, regardless of OBSE version), you don't have to worry about it.

Ah, it's a scope issue - gotcha

Just like declaring variables in functions (or methods in java parlance). You can't access those variables outside the scope of the function. Ob XP does have some array declarations in menu mode, but it's in a specific menu and is only valid for the duration of the menu. That's why I panicked a bit when you said they become invalid.

Another question: do strings declared while in menu mode need to be explicitly destroyed? Ob XP currently does, because once again, any strings declared in menu mode are not needed outside of that scope, so they are destroyed before the end of the menu mode block, but I'm curious if you actually have to do so.

Thanks for clarifying that.

This version of OBSE seems to cause my game to crash when I teleport. Has anyone else had that problem? I use teleportation often, so I may have to go back to v0018.

Posted: **Wed Sep 01, 2010 11:23 pm**

Quest Log Manager and Display Stats are now upgraded, where the array initialization is moved to GameMode. I recommend a clean save to get rid of any incorrect array references.

Sorry for the inconvenience

Upgraded from version 19 to 19b. Sound is now all messed up and sometimes space bar does not work to initialize conversations, open doors, handle objects
Get this at the end of the obse text documnet

Posted: **Thu Sep 02, 2010 12:03 am**

Got to test 19b a little bit myself too, and everything seemed to work just as intended here :foodndrink:

SetCurrentHealth on Inventory references now seem to work as I hoped, and I tested Fast Travel, sounds and conversations a bit, and they all worked here. Not a thorough test, but at least a good sign (for me).

Posted: **Wed Sep 01, 2010 6:56 pm**

Thank you so much for addressing 19 and 19a's issues so quickly. I love you. <3

Posted: **Wed Sep 01, 2010 9:29 am**

I don't know if anyone have asked this question before. :unsure:

Is it possible to download obse0019. with an http://img199.imageshack.us/img199/4754/searchfilepath.png such as \Oblivion\Data\obse\ and files is already in the corrects folders. Is this an idea you would consider to change the archive for newer obse versions?

That picture was taken just to show you what I've used for my own convenience instead of copying files into the correct folders.
You can ignore pluggy if you like and that has worked for me in the past without any issues.

Posted: **Wed Sep 01, 2010 6:06 pm**

I can *tentatively* say that the new version seems to have fixed the disappearing mouse pointer problem I've been having (I've played for ~6 hours now with no problems), so thank you for this update!

New function request: GetSize. This would return the size of an object, as listed in the Size column in the CS. See this http://i855.photobucket.com/albums/ab118/AndalayBay/Oblivion/SizeColumn.jpg. In itself, this function will be of limited utility, but I have found it is quite useful if you are trying to categorize a bunch of similar items by size. If such a function exists already, please let me know! But I've hunted around and didn't find anything. I see that there are a variety of functions and attributes available for inventory, but size doesn't seem to be one of them. GetWeight is available and it's this kind of information that I'm referring to.

Size appears to be calculated only for bound objects and derives from the attached mesh's NiTriShapeData::Radius. In fact, it seems to be the rounded off value of radius. I'm not sure if the value is stored in each TESBound object, but NifSE should be able to get it for you.

EDIT: It might in the editor. I'll take a look.

Actually I've been looking at objects with bhkBoxShape, which doesn't have a radius.

For example: folio04.nif
Dimensions of bhkBoxShape: x=1.5344, y=2.3025, z=0.4552
Minimum size: 0.4552

Size in CS: 19

I don't think this is available in NifSE yet because I asked ~~PacificMorrowind~~ (er, that would be DragoonWraith

) about GetDimensions, which is in NifLib. He said he hasn't done anything with collision at all yet. I thought the size might be easier since it seems to be in the base CS.

As I said, probably of limited utility, but I think it would be handy in certain circumstances.
