Native Wasm GC approach (emerging):
Hybrid approach:
A “WASM GC new” approach for Eaglercraft 1.12 aims to bring more native-like garbage-collected runtime behavior to browser-playable Minecraft, improving performance and memory use while posing engineering and compatibility challenges. The practical path forward is likely hybrid: develop a WASM-managed heap and GC when supported by browsers, paired with robust JS-based fallbacks and extensive testing. As WebAssembly GC features mature and browsers adopt them, Eaglercraft stands to benefit significantly from reduced overhead, improved frame stability, and a cleaner mapping from Java runtime semantics to the web platform.
If you want, I can:
The "story" of Eaglercraft 1.12.2 (WASM-GC) marks a major technological leap for the web-based Minecraft project, moving it from a standard JavaScript translation to a high-performance engine using WebAssembly (WASM) with Garbage Collection (GC). The Evolution of Eaglercraft 1.12.2
Originally, Eaglercraft brought version 1.5.2 and 1.8.8 to browsers by compiling Java to JavaScript. However, version 1.12.2—the "Combat Update"—is significantly more demanding. To handle the increased complexity, developers transitioned to the WASM-GC engine.
2x Performance Boost: The new WASM-GC engine provides roughly double the performance of previous versions, allowing 1.12.2 to run smoothly in modern browsers like Chrome and Firefox.
WASM-GC Integration: By utilizing the "Garbage Collection" proposal for WebAssembly, the game manages memory more efficiently, reducing "lag spikes" that often occurred during Java-to-JS execution.
Preserved Worlds: Despite the engine overhaul, the client is designed to preserve existing single-player worlds, ensuring players don't lose their progress during the transition.
Offline Capabilities: Developers have released WASM-GC Offline versions, allowing players to run the high-performance client without an active internet connection once loaded. Why WASM-GC Matters
Before this update, running 1.12.2 in a browser was often unplayable on lower-end hardware due to the overhead of JavaScript. The shift to WASM (a binary instruction format) allows the game to execute at near-native speeds. The addition of GC (Garbage Collection) is the "secret sauce" that allows the engine to handle Minecraft's Java-based memory management without the massive performance penalty of older translation methods.
You can experience the latest beta versions of this engine on platforms like MC.JS.COOL. 12.2 WASM version? Eaglercraft 1.12 WASM-GC(mcjs) - MC.JS.COOL Eaglercraft 1.12 WASM-GC Offline. play.mc.js.cool WebAssembly Support
Some public servers offer Eaglercraft 1.12 WASM GC – search for “Eaglercraft 1.12 WASM server list”. Join via IP/port in the client’s multiplayer menu.
Because WASM GC uses true object allocation, you can get better performance than old JS Eaglercraft, but watch for:
