Create Scenes

When you create a project, it contains an initial Scene (MyScene.wescene) that includes some base entities.

In Evergine scenes are created similarly to other assets.

Create a Scene Using Evergine Studio

There are two ways to create a Scene in Evergine Studio:

• In the Assets Details panel, right-click and select the Create scene menu item.

• Alternatively, in the main menu, select Assets > Create scene.

Note

When you create a Scene, the new asset will be placed in the currently selected Asset Folder, which is shown in the Project Explorer panel and the Assets Details panel.

Create a Scene by Code

To generate a new Scene using code, simply create a new class that extends the Scene class:

1. Create a new class in your Evergine project (e.g., MyScene.cs).
2. Make that class inherit from the Scene class.
3. You can override the following important methods:

Method	Description
CreateScene()	Method where all the scene entities are created and added to the Scene.
RegisterManagers()	Method where the SceneManagers are loaded. base.RegisterManagers() will register the default SceneManagers.
Start()	Called just before the Scene starts updating and drawing.
End()	Ends the Scene.
Pause()	Called when the Scene is paused. This can occur if the app is suspended or if it is manually paused through the ScreenContextManager.
Resume()	Resumes the Scene when it is paused.

Here is a code example:

public class MyScene : Scene
{
    public override void RegisterManagers()
    {
        base.RegisterManagers();
        this.Managers.AddManager(new Evergine.Bullet.BulletPhysicManager3D());        	
    }

    protected override void CreateScene()
    {
        // Add scene entities.

        // Create a camera
        var cameraEntity = new Entity("camera")
            .AddComponent(new Transform3D())
            .AddComponent(new Camera3D())
            .AddComponent(new FreeCamera3D());

        this.Managers.EntityManager.Add(cameraEntity);
    }
}
