  • Il2CppDumper

    Unity il2cpp reverse engineer

    Project mention: Engage absolutely uses Fates RN; a technical analysis | /r/fireemblem | 2023-01-19

    By using IL2CppDumper along with the game's global-metadata.dat file, we can generate headers and structs that we can use with Ghidra, a tool for disassembling code. Once we load Engage and these headers and structs into Ghidra, we can look for a particular function called App.BattleMath$$_IsProbabilityHit. This function is provided a displayed hit (or, as Intelligent Systems calls it, ratio) and is responsible for determining whether or not that attack will actually hit. Ghidra will try to automatically decompile the assembly code into something more readable, and while the results are sometimes mixed, here it's pretty clear what's going on. We can see how, when the displayed hit is less than 51 (or when it's 100), it simply multiplies the displayed hit by 100, and when the displayed hit is 51 or greater, it uses the sin function as described earlier:

  • open-project-1

    Unity Open Project #1: Chop Chop

    Project mention: Unity will quietly waive fees if developers switch to its ad monetisation | news.ycombinator.com | 2023-09-14

    I wish they'd go the way of Epic and make an actual game with their engine. They've tried a few times and given up each time. It's pretty embarrassing when they've done things like released a fully featured multiplayer FPS demo that doesn't actually work out of the box and has a custom editor tool manager, custom scene loader, and custom networking layer that were never merged into mainline unity. Meanwhile they still have no official stable networking module. The old functional one was sunset and the new ones are still in beta.


    > This project is based on Unity 2018.3

    > NOTE: Due to a bug in Unity 2018.3, you have to take the following step right after the initial import: 1 Search for Firstperson_Projection in the Project search field. Select the 4 shaders, right click and reimport them. 2 If you have script compile errors related to entities, you need to remove and re-install the entities package.

    > One day soon we will remove this note and there will be cake.

    > Once the editor is ready, open the Project Tools Window by navigating to FPS Sample > Windows > Project tools.

    > Keep this window docked as you will use it a lot. From here you can open the levels, build assetbundles and build standalone players.


    > Note: As of December 2021, Open Projects and Chop Chop are not in development anymore.

  • UIEffect

  • MessagePack for C# (.NET, .NET Core, Unity, Xamarin)

    Extremely Fast MessagePack Serializer for C#(.NET, .NET Core, Unity, Xamarin). / msgpack.org[C#]

    Project mention: Fury: 170x faster than JDK, fast serialization powered by JIT and Zero-copy | news.ycombinator.com | 2023-10-07

    Given it's a binary serialization framework, it should not be too difficult, because the domain is well-explored and numerous libraries exist in C# which address same goals that Fury does.

    More popular/newer examples are https://github.com/Cysharp/MemoryPack (which is similar to Fury with its own spec, C#-code first schema), https://github.com/MessagePack-CSharp/MessagePack-CSharp or even gRPC / Protobuf tooling https://github.com/grpc/grpc-dotnet

    Unity / XNA game patcher and plugin framework

    Project mention: (MODDED) Plugins target a wrong version of BepInEx ( and might not work until you update | /r/lethalcompany | 2023-12-06

    I've just found out the way to fix it. You have to download it from github (https://github.com/BepInEx/BepInEx/releases/tag/v5.4.22) clicking your system type's zip and then paste the core folder inside it where the actual one is (C:\Users\{username}\AppData\Roaming\Thunderstore Mod Manager\DataFolder\LethalCompany\profiles\{profile}\BepInEx).
