The autoblock bypass issue in LiquidBounce Nextgen has been a major concern within the Chinese user community. We strongly urge the development team to prioritize fixing this critical Block problem, as it severely compromises the PvP experience. Currently, many players consistently lose battles on PvP servers when facing opponents using well-known hacked clients that exploit this flaw.
Successfully resolving this Block issue would be a significant breakthrough for the project - especially considering this problem has persisted since the legacy versions and remained unfixed even before development was discontinued."
I am trying to run Legacy so I can play 1.8.9 on my macOS, on Mac15.0. Nextgen works fine but when Legacy has been providing me with the below error:
libc++abi: terminating due to uncaught exception of type NSException
An error occured:
Process exited with non-zero exit code: 7900.
Any help would be amazing.
ScriptAPI v1 compatibility
This script re-introduces the compatibility layer for ScriptAPI v1, which was removed in LiquidBounce b83, while adding a few tweaks.
Only works on LiquidBounce legacy, NOT LiquidBounce nextgen.
NEVER contact LiquidBounce staff about errors while using legacy scripts!
For help and support, contact me on Discord: ayyyax.
For updates to script, visit my repository.
How to install
Download the provided zip file.
Extract it into your LiquidBouce-1.8.9 folder
Insert your favourite legacy scripts in scriptapi-v1/scripts
Warnings
Some scripts will simply not work. If that happens, try and contact me to sort out the issue.
LiquidBounce will take longer to start up while using this script.
I have no idea how to write scripts, so this is really bad, but it kinda works lol
Tested and confirmed working scripts

I truly appreciate that this client has remained free and open-source, which is excellent and has given rise to many forks. However, I wonder if there has been consideration to develop an injectable client? I understand that technical expertise varies, but could we attempt to explore this path?
Take the example of CCBlueX/liquidbounce_lite, which uses DLL injection via Rust. While undoubtedly challenging (potentially taking at least two years to mature), could such an approach eventually become viable? Additionally, would an executable (EXE) based solution be worth exploring as an alternative?

some prompt files to use on LLMs, specifically for claude + continue.dev vscode extension, at .continue/prompts.
Note: the mods are only limited to those presented at the development environment of LiquidBounce NextGen.
When writing your script in typescript, expect inconsistencies with script API in js, but please report them to this repo if you can
Instruction (subject to change)
Adjust the order flexibly to your needs.
Generating the typescript definitions
Setup development environment for Liquidbounce NextGen
Clone LBNG, run git checkout 451cb31e9bf093fe07f9b28202bc2471921ea13d (for version 0.29.0 release) and launch with gradle ./gradlew runClient without intellij idea(recommened because of the sheer amount of memory it takes to generate the definition).
Place the LBNG-script/ts-defgen.js in your script folder for LiquidBounce
Build or download the latest released ts-generator jar from github, place it in your script folder as well.
Do a .script reload in your client, this should load the ts-defgen.js
Run the .ts-defgen command
See messages from chat and wait for around a few minute or more or less depending on your setup, this may take a while and also nearly 7GB of additional RAM (other than your intellij idea plus the what Minecraft needs in it's original state, causes OOM for me a lot of times xD).
Now you can find a types-gen folder in your script folder, this contains the generated typescript definitions.

Writing scripts with TypeScript Support
Run npm install in this directory.
copy the generated folder types-gen to generated-modules folder in the root of your project.
Run the script apply-patch with npm run apply-patches
Run npm install file:./generated-modules/types-gen/minecraft-yarn-definitions/ --no-save, no-save for now, not sure if I should do this.
Open the template.ts file and try start writing your script, you should see TypeScript type hints for all the classes that are available. vscode will automatically generate working imports, but you should not touch the import statement with @embedded namespace.
Run the script compile with npm like step 4 or npm run watch
Corresponding javascript file is generated in the dist directory, you can link this dist directory to your scripts directory in LB.
Contribution and TODOs
If you know how to better organize this project (architecture), please feel free to submit a PR.
If you find errors on generated definitions about Minecraft classes or LiquidBounce classes, please file your tick at ts-generator.
If you find a un-intended behavior in the ts-defgen.js, compile script or manually maintained definitions(TODO), please file an issue here.

Please fix the forgegradle problem and support for Scriptapi1 in b74
I'm really bored. Countless scripts can't be used. Countless problems and scripts need to be updated. This is a community, but it doesn't mean we need to work for free. Even if I write a tool that can convert api1 scripts into api2 scripts with one click, there are still a lot of error correction steps. Who doesn't want to use the latest version of liquidbond? But we can't give up our work, so please fix the forgegradle problem and support for Scriptapi1 in b74
