SDM Core
by Sixik
SDM Core is a library for script-based mod development, offering helpers for NBT data, custom serializers and multithreaded utilities.
What it does
Other mods built on this library can use its helpers for reading and writing NBT data, defining custom serializers for their own objects and running work across several threads. Its author describes it as a foundation for creating mod script elements, so most players meet it only as a dependency of other mods.
The library includes an integration with ImGui, a toolkit for building debug and developer interfaces. It is required by Ore Stages Reborn and SDM GameStages. Installation covers Fabric, Forge and NeoForge, and the environment is client and server, so the server and every player need it. Files cover 1.19.2, 1.20.1, 1.21 and 1.21.1, with 2.1.2 as the latest file for 1.21.1 on Fabric and NeoForge and 1.3.0 for 1.20.1 on Forge.
Key features
NBT handling
Helpers for working with NBT data let dependent mods read and write structured save information.
Custom serializers
Developers can define serializers for their own types so those objects can be stored and loaded.
Multithread utilities
A set of utilities lets dependent code run tasks across threads instead of only on the main thread.
ImGui integration
The library connects to ImGui, an immediate-mode interface toolkit, for building developer-facing windows.
