# Unity Addressables

> Unity 6 Addressables asset management group configuration, label + address conventions…

A complete discipline for managing assets with Unity 6 Addressables: domain-split groups, remote CDN bundles, mid-game content patches without an app-store resubmit, and strict AsyncOperationHandle lifecycle to prevent memory leaks. It lets you split an 800MB build into a slim ~150MB install plus on-demand CDN content while staying memory-safe and store-policy compliant.

## Use cases
- Shrinking install size to meet Apple 200MB OTA and Google 150MB base limits
- Shipping new biomes or event content as instant patches, no review wait
- Tier-switching low/mid/high atlas bundles per device capability
- Hunting memory leaks from missing handle Release calls
- One-time remote download of heavy cutscene or audio bundles
- Per-environment build profiles for dev, staging, and production

## Benefits
- Faster first install and higher store conversion from a slim download
- Push content fixes and events without waiting on store review
- Lower CDN egress cost through smart bundle and compression choices
- No more VRAM blowups and thermal throttling from leaked assets

## What’s included
- Domain-based group config (characters, environment, audio, VFX) with LZ4/LZMA guidance
- Load + Release patterns with try-finally for guaranteed cleanup
- Content-update workflow protecting content_state.bin for delta patches
- Pre-download size check with user-consent dialog and progress UI
- Graceful remote-fail fallback to local placeholder content
- Catalog version check on app start and a full verification checklist

## Who it’s for
Unity 6 mobile and live-service developers who need on-demand, patchable, memory-safe asset delivery within store size limits.

## How it runs
An 800MB build becomes a 150MB install with the rest streaming on demand from CDN. Behind that number sits a grouping, lifecycle and patching discipline that also keeps memory honest:
1. Splits assets into domain-isolated Addressables groups (Atlas_Characters, Atlas_Environment, Audio_Music, Audio_SFX, VFX) so one failed CDN download degrades gracefully instead of taking the whole game down. The 800MB build becomes roughly 150MB install plus on-demand remote bundles, inside Apple's 200MB OTA and Google's 150MB base limits.
2. Enforces the handle lifecycle on every load: each LoadAssetAsync wrapped in try-finally with a matching Addressables.Release, because a missed Release keeps a 100MB atlas resident and ends in thermal throttling. The checklist literally greps for load calls without a paired release.
3. Chooses compression per path: LZ4 for runtime hot-path bundles (5 to 15ms decompress, fits in a frame) and LZMA only for cold-path one-shot content like cutscene video where a 35 percent smaller download is worth slower decompression.
4. Runs three build profiles with environment parity: Development points at a local path, Staging and Production at their CDN buckets. Same code, only the profile variable URL changes, switched in CI by profile id.
5. Executes the content update workflow for store-free patching: build the baseline, archive content_state.bin per release (deleting it makes delta updates impossible), later run Update a Previous Build to generate only the changed bundles, sync them to the CDN, and let clients auto-detect the new catalog version on app start.
6. Protects the player experience: GetDownloadSizeAsync pre-checks every label and anything over 50MB triggers a consent dialog with a progress bar, remote failures fall back to a local placeholder asset with a retry queue, and all bundle URLs are HTTPS with hash verification.

## FAQ
### My game is a small single-platform build, do I still need Addressables discipline?
It pays off when install size, store limits, or live content matter. If you're nowhere near Apple's 200MB OTA or Google's 150MB base limit and never patch content remotely, plain Resources or direct references may be enough for now.

### How does a mid-game content patch actually skip the app-store resubmit?
The content-update workflow protects content_state.bin so only changed bundles are rebuilt as a delta, and the app checks catalog versions on start to pull new remote bundles from your CDN. The binary never changes, so there's nothing for the store to review.

### Does it host the CDN or pay for bundle delivery?
No. You bring your own CDN or object storage; the skill covers group configuration, compression choices that lower egress cost, pre-download consent dialogs, and graceful fallback when the remote fails. Hosting and bandwidth bills stay yours.
