📋 About This Mod
# English SuperAccessTransformer (SAT) is an open-source coremod for Minecraft 1.21+ that modifies access modifiers at runtime by injecting a Java Agent, converting most `private`, `protected`, and `final` members to `public`. It also includes a Gradle plugin, allowing the transformations to work in development environments without extra JVM arguments. ## Core Functionality **Runtime Bytecode Transformation**: Uses the `java.lang.instrument` API along with the ASM library to intercept class loading and modify bytecode. The transformation: + Removes `private`, `protected`, and `final` modifiers from fields and adds `public` + Removes `private`, `protected`, and `final` modifiers from methods (except `<clinit>`) and adds `public` + Skips interfaces and enum `$VALUES` fields ## Development Environment Support **Gradle Plugin Integration**: Add the SAT Gradle plugin to your project to enable transformation at development time. The plugin is compatible with both Fabric and NeoForge modules. ``` buildscript { dependencies { classpath 'io.github.yiyuyan:SuperAccessTransformerPlugin:1.000' } } apply plugin: 'io.github.yiyuyan.sat-plugin' ``` You can also find an example setup for Architectury NeoForge 1.21 at the `test` branch: (https://github.com/yiyuyan/SuperAccessTransformer/tree/test) ## Known Limitations & Notes + **Fabric Loader Dev Environment**: `Mob::rotlerp` and `WitherBoss::rotlerp` methods will **not** be transformed. + **NeoForge Mod List**: As a coremod using the `lowcodefml` loader, SAT does **not** appear in the NeoForge mod list. # 简体中文 SuperAccessTransformer(SAT)是一个面向 Minecraft 1.21+ 的开源 coremod,通过在运行时注入 Java Agent,将大多数 `private`、`protected` 和 `final` 修饰符转换为 `public`。该模组还提供 Gradle 插件,使得转换在开发环境中也能直接生效,无需额外 JVM 参数。 ## 核心功能 **运行时字节码转换**:利用 `java.lang.instrument` API 与 ASM 库拦截类加载过程并修改字节码。转换规则如下: + 移除字段的 `private`、`protected` 和 `final` 修饰符,并添加 `public` + 移除方法(`<clinit>` 除外)的 `private`、`protected` 和 `final` 修饰符,并添加 `public` + 跳过接口和枚举的 `$VALUES` 字段 ## 开发环境支持 通过 Gradle 插件可在开发环境中启用运行时转换,同时适用于 Fabric 与 NeoForge 模块. ``` buildscript { dependencies { classpath 'io.github.yiyuyan:SuperAccessTransformerPlugin:1.000' } } apply plugin: 'io.github.yiyuyan.sat-plugin' ``` 你也可以参考针对 Architectury NeoForge 1.21 的示例项目:(https://github.com/yiyuyan/SuperAccessTransformer/tree/test) ## 已知限制与提示 + **Fabric Loader 开发环境**:`Mob::rotlerp` 和 `WitherBoss::rotlerp` 这两个方法不会被转换。 + **NeoForge 模组列表**:该模组基于 `lowcodefml` 加载器,作为 coremod 不会出现在 NeoForge 模组列表中。

Runtime Bytecode Transformation: Uses the `java.lang.instrument` API along with the ASM library to intercept class loading and modify bytecode. The transformation:
+ Removes `private`, `protected`, and `final` modifiers from fields and adds `public`

## Development Environment Support
Gradle Plugin Integration: Add the SAT Gradle plugin to your project to enable transformation at development time. The plugin is compatible with both Fabric and NeoForge modules.
``` buildscript { dependencies { classpath 'io.github.yiyuyan:SuperAccessTransformerPlugin:1. 000' } } apply plugin: 'io.github.yiyuyan.sat-plugin' ```
You can also find an example setup for Architectury NeoForge 1. 21 at the `test` branch: (https://github.com/yiyuyan/SuperAccessTransformer/tree/test)
## Known Limitations & Notes
+ Fabric Loader Dev Environment: `Mob::rotlerp` and `WitherBoss::rotlerp` methods will not be transformed. + NeoForge Mod List: As a coremod using the `lowcodefml` loader, SAT does not appear in the NeoForge mod list.
