The Open Terraria API, known as OTAPI, is a low-level API for Terraria that rewrites and hooks into the official or modded binaries for others to use. OTAPI is primarily a server modification and is available as a cross platform package via NuGet. Version 3.0 is now a .NET9 library thanks to ModFramework being able to retarget the .NET4 vanilla assembly up to .NET9. This means that any mod you create can be written as a .NET9 module and later merged into the patched assembly thanks to MonoMod. Here is what is now possible: - Native Runtime hooks, just reference OTAPI.Runtime.dll and register to MonoMod events generated from the Terraria assembly. - Full .NET9 ecosystem and its performance improvements. No need for two targets such as Windows & Mono anymore either. - A new optional internal module system via ModFramework to load precompiled dll's, .cs files or even top level classes. - A strong set of libraries with methods and extensions to help you build more mods. - Create 1 file MonoMod patches to rewrite or inject new meta data to the assembly.
$ dotnet add package OTAPI.UpcomingNo README available.
