About TShock
From GitHub☕️⚡️TShock provides Terraria servers with server-side characters, anti-cheat, and community management tools.
TShock is a toolbox for Terraria servers and communities. That toolbox is jam packed with anti-cheat tools, server-side characters, groups, permissions, item bans, tons of commands, and limitless potential. It's one of a kind.
This is the readme for TShock developers and hackers. We're building out new TShock documentation for server operators and plugin developers, but this is a work-in-progress right now.
Developing TShock
If you want to contribute to TShock by sending a pull request or customize it to suit your own sparkly desires, this is the best starting point. By the end of this, you'll be able to build TShock from source, start to finish. More than that, though, you'll know how to start on the path of becoming an expert TShock developer.
This guide works assuming that you have the .NET 9 SDK installed and that you're familiar with the command line. If that doesn't describe you, you should be able to accomplish the same thing using Visual Studio 2022 or Visual Studio Code.
- Clone the repository:
git clone https://github.com/Pryaxis/TShock.git --recurse-submodules cd TShockto enter the repo.dotnet build. No really, that will build things!
If you want to run the TShockLauncher (which runs a server), run:
dotnet run --project TShockLauncher
To produce a packaged release (suitable for distribution), run:
cd TShockLauncherdotnet publish -r win-x64 -f net9.0 -c Release -p:PublishSingleFile=true --self-contained false
Note that in this example, you'd be building for win-x64. You can build for win-x64, osx-x64, linux-x64, linux-arm64, linux-arm. Your release will be in the TShockLauncher/bin/Release/net9.0/ folder under the architecture you specified.
Working with Terraria
Working with Terraria in TShock and in other Terraria Server API plugins is different from most other APIs. Due to the nature of how OTAPI works, you have direct access to all public fields in the Terraria namespace. This means that you can access Terraria member methods directly. TShock and other plugins do this quite often, mostly to modify the game world, send data, and receive data. Calls to Main are one such example of direct access to Terraria. This is the equivalent to net.minecraft.server (NMS) calls in CraftBukkit.
You might find yourself wondering where these fields are. Pryaxis provides the decompiled Sources to Terraria's server, updated with each release. These sources are made available to developers of TShock. If you have submitted a pull request to TShock, reach out on Discord to get access. In lieu of this, you can download ILSpy and decompile Terraria or the server itself.
Finally, you may be interested in developing other Terraria Server API plugins. The TShockResources organization has several plugins you can look at and build on. TShock is itself a plugin, and most plugins are open source. This gives you ample room to figure out where to go next.
