The Fallout Script Extender, or FOSE for short, is a modder's resource that expands the scripting capabilities of Fallout 3. It does so without modifying the Fallout3.exe or the G.E.C.K. files on disk, so there are no permanent side effects.

Compatibility:

FOSE supports these versions of Fallout 3 (from either a retail DVD or Steam):
- 1.0.0.15
- 1.1.0.35
- 1.4.0.6 (original release)
- 1.4.0.6 (alternate release, found on steam and some European patches)
- 1.5.0.22
- 1.6.0.3
- 1.7.0.3

FOSE is compatible with the 1.1.0.36 and 1.5.0.19 G.E.C.K.

Incompatibilities:
* FOSE is not compatible with the original, unpatched DVD or Steam version. Either version patched to 1.0.0.15 or 1.4.0.6 will work.
* FOSE is not compatible with the Direct2Drive (D2D) or the Russian version of Fallout 3 protected by StarForce. FOSE will never be compatible with these versions, as they are encrypted and it would be illegal to break the encryption.
* FOSE is currently incompatible with Windows Live, so when running via fose_loader.exe, Live will be disabled. Live functions as an anti-cheat mechanism, so it disables itself if it detects any in-memory modifications to the executable, despite the fact that Fallout has no multiplayer component. Since Live cannot tell the difference between the modifications we make and the modifications a cheating program would make, we will probably never be directly compatible. To download DLC and updates, simply launch Fallout normally. Live stores DLC and save files in a separate folder when active, so some things may need to be moved around - see the official Fallout forums for more information.

This initial release adds 189 new scripting functions including:
- basic input functions based on DX scancodes
- basic form list functions
- debugging console functions
- various weapon and inventory item Get and Set functions
- script versions of several console functions
- Looping functions (Label, Goto)
- GetCrosshairRef
- get and set game setting and INI functions
- loaded mod informtion functions
- reference walking functions
- Basic UI Functions (GetUIFloat, SetUIFloat, SetUIString)
- basic math and bit flag functions
- GetGameRestarted, GetGameLoaded
- temporary base form cloning functions

Sick new thread! When does the next version come out? Or did one just come out in the past couple of days? Thanks!

Also, if I said anything bad, please excuse me, I had a few too many.

I hope that current ammo count in clip (get/set) is under investigation.

Is there a function for returning the specific reference of an equipped weapon or anything handheld?

behippo,

Howdy.

Hey FOSE,

Just curious here. Would you be able to implement FOSE into the GECK in a way that we can use your custom condition functions on condition windows like the perks' and the quests'?
If you don't know what I mean, I mean like here: http://geck.gamesas.com/index.php/Category:Conditions#Function_Parameters
The available options only show vanilla functions - I'm lately needing them, particularly for perks.

Thanks.

getaltcontrol doesn't seem to return the correct DX scancode.
It will return 0 if the control is set to LeftMousebutton and will return 1 if the control is set to RightMousebutton for example.

A humble request:

Is it possible to get "IsPersistent" in FOSE. I am looking for a "clean" solution for my slave mod and found no good way to detect if a actor is a persistant reference or not.

Do the latest versions of FOSE require an upgrade to 1.7?

I found that some of my older mods will not work with the 1.7 patch (they CTD during savegame loading).

I'm sure this has been requested before, but would a clickable map be possible? Or detecting where the players map marker is?

I was just looking through the Documentation, and I noticed there is no Get/Set function for some of the flags on weapons (NPCs Use Ammo, etc.) any plans to add these?

So V2 will not support 1.6.

Would it be possible to make a function to get whether or not a given NPC ref can see the player?
