🎮 Game Quality Gates

Stop shipping games with phantom timers, memory leaks, and double-spend exploits. A battle-tested quality standard for H5/Canvas/WebGL games.

💀 The Problem

Every feature works fine alone. They break in combination:

Feature A	+ Feature B	= Bug
Slow powerup	Paddle collision	Speed value overwritten
Multi-ball	Main ball death	Orphan sub-balls still scoring
Power-up falling	Player dies	Ghost objects after game over
Game over	Buff timers	Phantom timer modifies destroyed object 💥

These aren't edge cases — they're the #1 cause of game bugs. After fixing 70+ of these bugs in production H5 games, we encoded the prevention patterns into 12 universal rules.

📋 The 12 Universal Rules

#	Rule	Prevents
1	🔄 Single Cleanup Entry Point	"Fixed in A, forgot in B"
2	⚡ Respect Active Buffs	Buff silently overwritten
3	📦 Cache Before Destroy	Reading dead object props
4	⏰ Timers Follow Lifecycle	Phantom timers after game over
5	🖥️ Frame-Rate Independent	30fps device = half speed
6	🚪 Scene Switch = Full Cleanup	Memory grows per restart
7	🔊 Audio Lifecycle	iOS silent, background still playing
8	👆 Input Safety	Double-buy, rapid-fire exploits
9	💾 Save State Versioning	Broken saves after update
10	🌐 Network Fault Tolerance	Game freezes on bad network
11	📦 Asset Loading Strategy	White screen, missing textures
12	🛡️ Anti-Cheat Baseline	Score injection, payment bypass

🎯 Engine-Specific Guides

Phaser 3 (Arcade Physics)

Multi-touch pointer.id tracking (the finger-swap bug)
physics.pause() ≠ time pause (the phantom timer gotcha)
OVERLAP_BIAS tuning (3-4 recommended)
Physics group clear(true, true) between levels

Three.js (WebGL/3D)

The dispose trio: geometry + material + texture (VRAM leak prevention)
GLB compression pipeline: 14MB → 800KB (94% reduction)
gltf-transform prune Skin deletion pitfall on rigged models
Animation crossfade state machine

Anti-Cheat

One-time raid tokens (link start → submit)
Duration + score sanity checks
Atomic purchase endpoints (no split deduct/grant)

✅ Pre-Deploy Checklist (Quick)

🔴 Universal (every game)
  □ New objects in cleanupGameState()?
  □ New timers cancelled in cleanup?
  □ Buffs respected when modifying attributes?
  □ Data cached before destroy()?
  □ Delta time used for movement?
  □ No memory leaks across scenes?
  □ Audio pauses on background?
  □ Purchase has click-lock?
  □ Saves have version + migration?
  □ Network has timeout + fallback?
  □ Asset failure degrades gracefully?
  □ Critical ops server-validated?

🟡 Mobile: multi-touch IDs, iOS audio resume, WeChat WebView compat
🔵 Phaser: clear(true,true), OVERLAP_BIAS, time+physics pause sync
🟣 Three.js: dispose trio, Draco loader, fadeIn/fadeOut transitions
