This paper explores the technical architecture of Eaglercraft 1.12, a web-based port of the popular sandbox video game Minecraft (Java Edition version 1.12.2). Unlike previous iterations which relied on a manual translation of Java bytecode to JavaScript (via the TeaVM toolchain), the 1.12 port leverages modern WebAssembly (Wasm) capabilities, specifically the experimental WebAssembly Garbage Collection (Wasm GC) proposal. This document details the compilation pipeline, the rendering infrastructure utilizing WebGL 2.0, and the implications of Wasm GC on performance and memory management for complex Java-based applications running within a browser environment. eaglercraft 1.12 wasm gc

Version 1.12 is often chosen as the "sweet spot" for these builds. It is the final version before the "Flattening," a massive internal rewrite of Minecraft's engine that occurred in 1.13. This makes 1.12 significantly easier to optimize for the web while still supporting a vast array of popular mods and multiplayer features. Ensure this is ON in your browser settings

To manage memory effectively, Eaglercraft 1.12 uses a combination of WASM's built-in memory management features and a custom GC system. The WASM module allocates memory for the game's data structures, and the GC system periodically cleans up memory occupied by objects that are no longer needed. This makes 1
