Installing RedEngine

RedEngine is distributed through the Unity Asset Store. Import it into the Unity project where you want to use the framework, then let Unity resolve and compile its package dependencies.

Before you begin

You need:

• Unity 6000.0 or newer;
• Photon Fusion 2 configured for the project;
• the dependencies declared in RedEngine's package.json.

The package uses Unity's Input System. The legacy UnityEngine.Input API is not part of the runtime.

Import from the Asset Store

1. Add RedEngine to My Assets on the Unity Asset Store.
2. Open Window > Package Manager in the target project.
3. Select My Assets, find RedEngine Framework, and choose Download or Import.
4. Import the package contents and wait for Unity to finish compilation.

After an update, keep the project open until script compilation and Addressables refresh have both finished. Review the Release Notice before upgrading an existing multiplayer project.

Confirm the installation

After compilation:

1. open Tools > RedEngine > Welcome;
2. confirm RedEngine appears in Package Manager;
3. create or select Assets/Resources/EngineSettings.asset;
4. open the Fusion Network Project Config and confirm the App Id and peer mode.

Do not create multiple EngineSettings assets under Resources. RedEngine expects one default asset.

Assembly references

RedEngine is split into focused assemblies. Add only the modules your game assembly uses—for example, RedEngine.Core for actors and world lifecycle, then RedEngine.Gameplay.AbilitySystem if that code uses abilities. There is no umbrella RedEngine.Gameplay assembly.
