Help Using FO4Edit to Make a Replacer Mod

[fairplayer916]

Put simply, Id like to learn how to completely replace one weapons existence in the game with a weapon mod.

 

Specifically i want to replace the in game semi-auto and full-auto pipe rifle/pistol with YonaTakus' "Defense Gun"

http://www.nexusmods.com/fallout4/mods/14598/?

 

 

I THINK the simplest way to do this would be to change the form id call from the old weapon to the new one.

 

Problem is i dont know how to do that. I would appreciate any and all help with this.

 

Thank you in advance.

Would be much easier just to replace the original mesh.

well the file structure of the defense gun mod is alittle weird. figured the attachments wouldnt sink up if i jsut swapped the main mesh/textures

When it comes to replacing placed references, that's easy. Simply change the "NAME" element in all REFR records.

 

A small excerpt-come-example from one of my scripts:

 

 

eName := ElementBySignature(e, 'NAME');
    strName := GetEditValue(eName);
    
    
    for iCounter := 0 to iNumEntriesInList - 1 do begin
    
        if strName = tstrlistOriginal[iCounter] then //Compare the reference's placed object. If it matches an entry in our list
            SetEditValue(eName, tstrlistReplace[iCounter]); //Replace it with the object in our second list
            
    end;

 

The whole script:

 

 

 

 

unit userscript;

var
    tstrlistOriginal, tstrlistReplace: TStringList;
    //tstrlistOriginal Will contain all the NAME values that we're looking for.
    //tstrlistReplace Will contain the ones we want to change them to.
    
    //It's done on a line by line basis. The script looks through each line in
    //tstrlistOriginal. Once it finds a match with the currently selected record,
    //it looks in tstrlistReplace at the same line number, to get the replacement.
    iNumEntriesInList: integer;

function Initialize: integer;
begin

    tstrlistOriginal := TStringList.Create;
    tstrlistOriginal.LoadFromFile(ProgramPath + 'Edit Scripts\FyTy\NAME Replace - Source.txt');
    
    tstrlistReplace := TStringList.Create;
    tstrlistReplace.LoadFromFile(ProgramPath + 'Edit Scripts\FyTy\NAME Replace - Replacement.txt');
    
    iNumEntriesInList := tstrlistOriginal.Count;
    
end;


function Process(e: IInterface): integer;
var
    eName: IInterface;
    strName: string;
    iCounter: integer;
begin
    
    if Signature(e) <> 'ACHR' then
        if Signature(e) <> 'REFR' then
            exit;
    
  AddMessage('Processing: ' + FullPath(e));

    eName := ElementBySignature(e, 'NAME');
    strName := GetEditValue(eName);
    
    
    for iCounter := 0 to iNumEntriesInList - 1 do begin
    
        if strName = tstrlistOriginal[iCounter] then
            SetEditValue(eName, tstrlistReplace[iCounter]);
            
    end;
    
    
end;


function Finalize: integer;
begin
    
    
    
end;

end.

 

 

 

As for changing entries in leveled lists and NPC inventories, it's pretty much the same gig, but you have to loop through all the entries in NPC inventories, in form lists and in leveled items.

 

Here's the documentation for xEdit scripting: http://www.creationkit.com/index.php?title=TES5Edit_Scripting_Functions

 

Luckily, this is a really easy task, so it's a good first-time foray into scripting with pascal.
