FDLib
by FINDERFEED
With FDLib installed, Bedrock models, Bedrock animations, cutscenes, custom bossbars and JSON configs all load through one utility library made for FINDERFEED's own mods.
What it does
FDLib is a collection of utilities that the author built for their own mods. Its main parts are a Bedrock model loader, which reads model files but does not support some parameters such as mirror UV, and a Bedrock animation loader that accepts math-based keyframes. Packet registration is simplified, and JSON configs are supported for mods that use them.
The library also includes cutscene playback, custom bossbars and an optional impact frame effect that can be turned off in the FDLib config. Other utility and math code is included as well. Qliphoth Awakening, Raids:Enhanced and Cinematic Cataclysm all require it. Files are published for Forge and NeoForge, for 1.20.1 and 1.21.1, and the environment is client and server. The license is All rights reserved, so the code is not open source, though public source links are available.
Key features
Model rendering
Reads Bedrock-format models for display in game. Some parameters, such as mirror UV, are not supported.
Math-driven animation
Plays animations defined with math-based keyframes, so motion can be described with expressions.
Cutscenes
Plays scripted camera sequences on the client. The /fdlib fix cutscene command ends the current cutscene immediately.
Custom bossbars
Displays bossbars with custom settings for mods that need more than the vanilla bar.
Impact frames
A screen effect that can be disabled in the FDLib config for players who prefer not to see it.
JSON configs and packets
Supports JSON configuration files and simple packet registration for mod developers.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
