Skybound Skill Asset Integration

매 한 줄

"매 skill 은 매 asset bundle 의 contract 다.". Skybound Skill Asset Integration 은 War Commander 의 Skybound faction 새로운 skill 추가 시, design data (json), VFX (particle), audio, animation, UI icon 의 5 개 asset 을 단일 manifest 로 묶고 매 client 가 atomic 으로 load 하도록 하는 pipeline. 매 2026 LiveOps 의 hot-patch skill drop 의 표준 패턴 — skill 추가 시 client 강제 update 없이 OTA 적용 가능.

매 핵심

매 Pipeline Stages

1. Design: skill stat json (cooldown, damage, type)
2. VFX: particle effect bundle (Unity/Unreal addressable)
3. Audio: SFX wav + mixer routing
4. Animation: skeletal anim clip + state machine entry
5. UI: icon, tooltip locale strings

매 Manifest Contract

• 매 skill = 매 unique skillId
• manifest 는 asset hash + version + dependencies
• client 가 매 skill 사용 시 manifest verify → fallback to default if missing
• 매 OTA delivery: CDN-backed, signed manifest

매 응용

1. War Commander Skybound expansion: monthly new skill drop.
2. Generic faction-DLC pipeline.
3. Live event one-shot skills.

💻 패턴

Pattern 1 — Manifest schema

interface SkillManifest {
  skillId: string;
  version: string;
  designJson: AssetRef;
  vfxBundle: AssetRef;
  audioBundle: AssetRef;
  animClip: AssetRef;
  uiIcon: AssetRef;
  signature: string; // 매 server-signed
}
interface AssetRef { url: string; hash: string; sizeBytes: number; }

Pattern 2 — Atomic loader

async function loadSkill(manifest: SkillManifest): Promise<Skill> {
  await verifySignature(manifest);
  const [design, vfx, audio, anim, icon] = await Promise.all([
    fetchAsset(manifest.designJson),
    fetchAsset(manifest.vfxBundle),
    fetchAsset(manifest.audioBundle),
    fetchAsset(manifest.animClip),
    fetchAsset(manifest.uiIcon),
  ]);
  for (const [a, ref] of [
    [design, manifest.designJson], [vfx, manifest.vfxBundle],
    [audio, manifest.audioBundle], [anim, manifest.animClip], [icon, manifest.uiIcon],
  ] as const) {
    if (sha256(a) !== ref.hash) throw new Error('HASH_MISMATCH');
  }
  return assembleSkill(design, vfx, audio, anim, icon);
}

Pattern 3 — Fallback to default

async function loadSkillSafe(skillId: string): Promise<Skill> {
  try {
    const manifest = await fetchManifest(skillId);
    return await loadSkill(manifest);
  } catch (e) {
    logger.warn('Skill load failed; falling back', { skillId, err: e });
    return loadDefaultSkill();
  }
}

Pattern 4 — Hot-patch detection

async function checkForSkillUpdate(skillId: string, currentVersion: string): Promise<boolean> {
  const remote = await fetchManifestHead(skillId);
  return remote.version !== currentVersion;
}

Pattern 5 — Server-side signing

function signManifest(manifest: Omit<SkillManifest, 'signature'>, key: PrivateKey): string {
  const payload = canonicalJson(manifest);
  return ed25519.sign(key, payload).toString('hex');
}

Pattern 6 — CDN cache prewarming

async function prewarmManifests(skillIds: string[]): Promise<void> {
  const manifests = await Promise.all(skillIds.map(fetchManifest));
  const refs = manifests.flatMap(m => [m.designJson, m.vfxBundle, m.audioBundle, m.animClip, m.uiIcon]);
  await Promise.all(refs.map(r => prefetch(r.url)));
}

Pattern 7 — Localization fallback

function resolveTooltip(localeStrings: Record<string, string>, locale: string): string {
  return localeStrings[locale] ?? localeStrings['en'] ?? '<missing>';
}

매 결정 기준

상황	Approach
Mobile + bandwidth concern	Lazy-load: only fetch on first use
Frequent hot-drop skill	Prewarm all active manifests on app start
Dev/testing	Local override manifest
Highly competitive PvP	Mandatory pre-load to prevent visual desync

기본값: lazy-load + prewarm popular skills, mandatory hash verify, ed25519 signature, fallback to default skill.

🤖 LLM 활용

언제: skill OTA 파이프라인 설계, manifest schema 검토, asset versioning. 언제 X: built-in only static skill 게임 — pipeline overhead 불필요.

❌ 안티패턴

• No signature verify: 매 client 가 매 임의 manifest 로 skill replace 가능 → cheat.
• No hash check: 매 corrupted asset → 매 silent crash.
• All-or-nothing load: 매 single asset 실패 → 매 entire skill 사용 불가 (fallback 누락).
• Cache poisoning: CDN edge 의 stale manifest → version drift.

🧪 검증 / 중복

• Verified (Unity Addressables docs, Unreal Pak system, Skybound expansion notes).
• 신뢰도 B.
