Decompiling fails on setdefaults1, for some reason.

[blapanda2]

Seems not to be a conflicting issue, but I need it to make some adjustments to items and Co.
The required method is, on the other hand, not available, for whatever reason. The assembly has its ReLogic.dll (extracted from the executable) and yet I am getting this error for the first 1-999 items:

Anyone figured out how to completely decompile the client yet?

I tried decompiling it myself and I got the same error. I'm not very knowledgeable when it comes to how decompilers actually work, but if you really wanted to fix it you'd have to download dnSpy's source from ****** and fix the decompiler yourself. You could do this by removing this check which is dangerous or by learning how to actually fix it properly. There is another option though and that's Harmony, you can find it on ******, it's a simple patching library you can use if you really need to alter SetDefaults1.

Hope this helps.

I use iLspy to decompile the client, select C# 8.0, add dependencies from Terraria's resources (relogic.dll and stuff). When it's done decompiling (after 1-2mins) open csproj and update .net framework to 4.5 at least. Go to properties -> compilation -> advanced -> select language version to the second option. There's one issue in the whole project, but you can easly remove it.

I have an issue with Terraria.Localization though, it's not fully working for me, trying to figure this out.

Thanks. If this works with ILSpy, I could simply drag over the method segment to dnspy. I find it quite comfy using that tool atm.

Edit: This actually worked out quite as expected and wanted, the setdefaults1 gets decompiled perfectly. Thanks again!

[HiImKyle]

Can I ask why you guys are decompiling the entire thing?

That works for me. I'd spent hours trying with a dnspy version and fixing hundreds of errors only for it to refuse to load any assets when I actually got it to boot. Your method I only had to add System.Xml and it built fine. (Couldn't change language version, possibly because I'm using VS2019)

For the Terraria.Localization, are you referring to some text elements not having the correct localized text? (As in, text might be "UI.HoverControlSettingIsHold" instead of "Hover Controls: Hold"?). Just renaming the standard "Content.en-US.json" to something like "Content.en-US.Fix.json" should work - for some reason it has trouble finding them. I'm looking into fixing it in the code itself, but it seems to be part of the System Assembly class so might not be able to fix it that way.
Edit: It has to do with how the files get packed into the exe, which I have zero clue how to fix, but it's a start

to fix the localization issue only have to create a new folder named Terraria.Localization.Content then move all languages over there
so it looks like

• Terraria.Localization.Content
  
  • en-US.Game.json
  • en-US.Items.json
  • en-US.json
  • en-US.Legacy.json
  • en-US.NPCs.json
  • and the
  • rest json files

That's because it has everything needed, after compilation it creates the whole .exe file which is easy to work with. VS has a nice autocompletion for the entire code, i find that better working than searching for some code I want to use in iLspy/dnspy. Anyways that's the only thing I know for now, as I just started playing with terraria code and it works pretty well. Do you have any better way that you can share with us?

[michael53239]

DNSPY and any other ways just takes too long as you would have to decompile each time rather than a single time.

[blapanda2]

dnSpy seems to cause a lot of issues, when compiling. Randomly changes stuff and/or completely breaks UI mechanics and such.
Decompiling with ILSpy is good, also tried to save it as a C# Project, but those errors ... are literally killing me. 973 errors. Am I doing something wrong here while using ILSpy as a C# exporter?
Using VS2015.

Using VS2015.

The way that worked for me was deavis' method above.
Here's what I did, step by step:

1. Latest ILSpy (6.0.0.5671-preview3)
2. Get the .dll files - you can get them from decompiling easily enough - and drag them into the ILSpy Assemblies list
3. Set it to C# 8.0 / VS 2019
4. Decompile
5. In the .csproj file change the .net version to 4.5 - when I opened VS2019 it prompted me to increase it to 4.6.1, depends on installed version
6. Open with Visual Studio (I know 2019 Community works, unsure about earlier versions)
7. Add System.Xml to the references to fix the single error that appears
8. Fix the localization stuff (i.e. either rename Content.en-US.json to Content.en-US.Fix.json, or putting them into a Terraria.Localization.Content folder)
9. In Terraria -> Properties -> Build Events add a post-build event:
   
   call "$(DevEnvDir)..\tools\vsdevcmd.bat"
   editbin /largeaddressaware "$(TargetPath)"
10. Build

Don't forget you have to have the XNA framework stuff installed somewhere. I forget how I installed it, since I did so years ago, but google "Visual Studio 2017 XNA Setup" and there should be a result from a site called flatredbull that has a link to an installable version of XNA (since the official one sometimes has trouble installing) - You should just be able to install it from that download and not have to follow the instructions on the site, but I can't guarantee anything.

dnSpy has the option to modify / recompile individual methods. It's fine if you're only making small tweaks, but I prefer to have the entire decompiled code available since i find it easier to search that way.

So far so good, nothing different for the decompiling section (btw. right clicking and using "Load Dependencies" is a bit faster :P), maybe it is the VS version I am using. VS 2015 Enterprise. Currently downloading the VS Community one, ticked the C# and .NET stuffs, also some optional .NET 4.X.X deps.
Will report back, when it's installed and ready to continue.

Edit:
Going to check on it tomorrow.

[warbob5000]

Just a question about "Add System.Xml to the references", a blank System.Xml file or a predefined from somewhere? Because there aren't any files inside the decompiled structure neither in ILSpy nor the new src-folder.

In Visual Studio, when you add references you can choose from ones which VS already knows about - System.Xml being one of those. No need to find any files. You should also be able to click on the error and use Visual Studio's error fixing option to add the required references.

Yea, just saw it amongst the other windows dep system files. Going to check it tomorrow. Thanks so far!

Btw. Ionic.Zip.CF, Newtonsoft.Json, RailSDK.Net and (for me illogically) Steamworks.NET are missing (for a GOG copy ...? makes no sense).

I imagine the code is 99% similar between the Steam and GoG versions, so it'd be easier to leave in the Steam stuff and just not have it initialize. If I had a GoG version I'd check the exact differences.

The Ionic.Zip.CF etc stuff should all be included. ILSpy extracts them as Libraries.Ionic.CF.dll or something similar. Dotpeek puts them into e.g. Libraries\Ionic\CF.dll. With them loaded into ILSpy I didn't even need to import them separately into Visual Studio. In ILSpy when you click on References under Terraria it should say that they were successfully found. If Visual Studio still complains, you might have to add them as references manually.
