Harmony VS dnSpy

Some more details https://github.com/pardeike/Harmony/issues/424

Here's what you're looking for.

Probably a little out of your scope but the library Harmony you can write patches (detours) on methods. Using get/set instead of a field would allow you to override the property's method. Let's say you wanted to write something to always have the name uppercase. You could patch the constructor and set this.name = this.name.ToUpper() but that field is publicly assignable so you can't really enforce that. On the other hand with a property you can override the set method to say this._name = value.ToUpper().

It's kind of a subtle distinction that I think was lost between the posted article and the original article it was responding to, but I don't think the kinds of reflection capabilities that Roslyn provides is what the author intended. The specific example given in the referenced article for "Higher-order programs" specifically refers to the ability to replace function implementations at runtime without interrupting the program, and specifically calls out hot-code reloading (such as what Java provides) as a deficient form of similar functionality. This is closer to the type of functionality libraries like Harmony provide, but even that solution requires including the library and instrumenting your code ahead of time.

https://github.com/pardeike/Harmony harmony lets you patch functions at runtime, kind of like a dll injection / memory edit

Download Harmony 2 and put net472 version of the library into GordianQuest_Data\Managed

I'd recommend looking into Harmomy and seeing if you're able to use it. It makes modifying DLLs pretty convenient.

Protip: Use a debugger like dnSpy or Visual studio to trace the source of error, by stepping the program line by line. You can restart with dnSpy attached.

Download dnSpy, Open the file "assembly_valheim.dll", Select view and then Assembly Explorer, search for DLCMan class (if you have trouble there is a search tool in the top bar, doing so you'll find the whole class), went to the correct lines (50, 79, 97 even if for me it was actually 98), right click on edit method/class (might be better to use method) and change the " return false; " to " return true; ". After the process compile again and there you have it.

To inspect the code, I recommend dnSpy. https://github.com/dnSpy/dnSpy You want to run it on the Assembly-CSharp.dll file from _Data/Managed. Then you can view the source code. I searched the entire project for the word "pause" until I found something that looked relevant. Luckily, the code for this game is pretty well written and well laid out.

It's dnSpy.

Great question! The tool I used, DNSpy, has the ability to patch in opcodes. So I just put in the instructions needed as essentially assembly, and I did so by just writing bytes into the existing executable. The two I used were ldc.i4 to put an integer onto the stack, and then mul to multiply it with the existing value.

.NET is super easy to reverse, you don't need Ghidra, go try dnSpy, that should do the trick.

Code Creation. Unfortunately, I don't have more information on the code of the game. This is the part I need help with. I'm quite familiar with HTML, CSS, and Javascript, but haven't really touched C#. The best that I've managed is opening Kitchen.Common.dll and KitchenMode.dll in dnSpy (https://github.com/dnSpy/dnSpy) and looking at the class and struct names, recognizing that some of the contents of those dll files which start with C, like CAppliance, are components of entities in the game, and can be used to retrieve entities somehow. I have no idea how to use the classes, like GrabItems or CreateNewMesses. Who knows if either of those do anything? Oh, and making an item or appliance? No idea.
