What is it?

TerrariaInjector is a program to inject harmony patches in to Terraria. Though it should work with any XNA/.net Applications.

How to install?

Simply put TerrariaInjector.exe and download the latest 0Harmony.dll from here (choose the one in the net35 folder) into your terraria installation folder and run it. Because of how it works, you will need to run the injector every time you want to play with mods/patches.

How does it work?

TerrariaInjector first checks for Terraria.exe in the current dir, and then loads it into itself. It then loads the embedded dependencies from the game. After it will load the libraries dll in the mod folder. The default Terraria save folder is then checked, and injects the path into a field. This is a workaround for the issue with the main class now being static. Which also means that TerrariaInjector doesn't support any other save paths. The patched game assembly is then invoked, starting the game.

Folder Structure

By default, TerrariaInjector looks for mods in:

• Mods/ folder (original structure)

You can also use a custom folder structure via INI config file:

• TerrariaModder/core/config.ini or Mods/config.ini defines folder paths
• Example config:

[Paths]
rootFolder=TerrariaModder
coreFolder=core
depsFolder=core/deps
modsFolder=mods
logsFolder=core/logs

Server Support

TerrariaInjector automatically detects TerrariaServer.exe and skips UI-related patches.

Loading Blocked DLLs

Uses Assembly.UnsafeLoadFrom() to load DLLs without requiring manual unblocking or .exe.config files. Downloaded DLLs from the internet work automatically.

How to create a patch/mod

Basic knowledge of HarmonyLib is required. You also need to reference both Harmony(0Harmony.dll) and Terraria(Terraria.exe). Each mod can have a Init(or Initialize) and a PrePatch method, which each get run at initialization and before patching the game. For and example/template look at the template.cs file in the 'Extra' folder to see an example made by deltaone. You can also use the files in the 'Extra/ModCompile' to help with compiling, just remember to change the modname in the bat file.

How to target another game

simple make a target file in the modfolder of the game, with the name of the game with the extension eg. 'Terraria.exe'. For an example check the target file in the 'Extra' folder.
