Ship Unity games on the Gully stack

Create a private repo from the template

Every Gully Studio game starts from gully-studio-unity-template and stays private: Asset Store content may ship inside a build but never as source (Unity Asset Store EULA). The hygiene CI fails a public repo.

Not on the gully-labs org yet? Email your GitHub username and you are added (open to every studio developer; the repo is private only because of the Asset Store EULA). Details: Getting started (opens in a new tab).

Git LFS and UnityYAMLMerge

Binaries (textures, models, audio, video) go to Git LFS; scenes and prefabs merge with Unity's Smart Merge. Run once per clone:

Never commit Library/, Temp/, Obj/, Build/, Logs/ or UserSettings/; the template's .gitignore already excludes them.

Open with Unity 6 LTS

Unity Hub opens the editor pinned in ProjectSettings/ProjectVersion.txt (6000.0.58f1 today). Force Text serialization and Visible Meta Files are already set. On first open Unity generates the rest of ProjectSettings/ and Packages/packages-lock.json: commit both.

Then set the product name and the bundle id xyz.gullystudio.<game> in Project Settings › Player.

Gully Game SDK (UPM)

The template already references the SDK. In another project, Package Manager › Add package from git URL, or pin it in Packages/manifest.json:

using GullyLabs.GameSdk;
// Gully Chain reads: public testnet RPC, or your Gully RPC key in production
var rpc = new JsonRpcClient();
long block = await rpc.BlockNumberAsync();   // chain 485590

Turn on GameCI builds

Add the Unity licence secrets to the repo (never to files), then switch the Unity workflow on. Builds: Windows, Linux dedicated server, Android, WebGL.

gh secret set UNITY_EMAIL -R gully-labs/<game>
gh secret set UNITY_PASSWORD -R gully-labs/<game>
gh secret set UNITY_SERIAL -R gully-labs/<game>     # or UNITY_LICENSE for a Personal .ulf
gh variable set UNITY_CI --body true -R gully-labs/<game>

Next: Release and CI (opens in a new tab) and Store policy (opens in a new tab).
