Scene Types

Scene Types

In order to load/unload scene with uFrame, a scene must contain a single root game object that is a parent to all other game objects in the scene.

This root game object needs to have a Scene Type component attached in order to be recognized by uFrame as a root game object.

Scene Type node defines how to load a scene and allows for unloading the scene. You can create a Scene Type node in the MVVMGraph in the designer.

Generated Scene Types

public class UISceneBase : Scene {
    
    public override string DefaultKernelScene {
        get {
            return "KernelScene";
        }
    }
    
    public virtual UISceneSettings Settings {
        get {
            return _SettingsObject as UISceneSettings;
        }
        set {
            _SettingsObject = value;
        }
    }
}

Generated Scene Loaders

A scene loader is generated for every scene type that exists in the graph.

The scene loader lives as a game object on the [uFrame Kernel](uFrame Kernel). When a scene with the corresponding Scene Type is loaded, the scene loader will get a reference to the Scene Type instance and allow you to load the scene accordingly. That gives a very fine grained control on how scenes are loaded and unloaded.
