Gc: Eaglercraft 112 Wasm

Feature: Eaglercraft 1.12 – The WASM Garbage Collection Breakthrough

For years, the promise of "Minecraft in a browser tab" came with asterisks. Lag spikes. Memory leaks. Tab crashes. Then came Eaglercraft 1.12, and with it, a quiet revolution under the hood: WASM Garbage Collection (WASM GC).

The original Eaglercraft focused on older Minecraft versions (e.g., 1.5.2, 1.8.8). However, the community has pushed toward Minecraft 1.12.2, a highly modded and feature-rich version. eaglercraft 112 wasm gc

The result was playable, but never "smooth." Enter WebAssembly (WASM). Feature: Eaglercraft 1

This write-up explores how Eaglercraft 1.12 implements WASM GC, its performance benefits, and the trade-offs compared to earlier JavaScript-based or manual-memory-managed WASM approaches. Metrics to collect: frame time, JS-Wasm crossings per

7. Performance Expectations & Benchmarks

  • Metrics to collect: frame time, JS-Wasm crossings per frame, allocation rate (objects/sec), GC pause times, memory footprint, network latency for deserialization.
  • Hypothesis: For heavy object-focused workloads (chunks, entities), Wasm GC can reduce per-tick CPU overhead by 15–40% vs. linear-memory object emulation and reduce JS glue.
  • Validate with microbenchmarks (allocation/collection), mid-level tests (chunk generation), and full-play tests.

Final rating: 9.5/10
(Only losing half a point for the Safari lag and the experimental modding support.)

Direct Hardware Utilization: Unlike JavaScript, which is interpreted line-by-line, WebAssembly runs as near-native machine code directly on your CPU and GPU.
