Create scenes

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

In Evergine scenes are created like another Asset.

Create scene from Evergine Studio

There are two ways of creating a Scene from Evergine Studio.

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

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

Note

When creating a Scene, the new asset will be placed in the current selected Asset Folder, the one selected in Project Explorer panel and the one showed in Assets Details panel.

Create a scene by code

To generate a new Scene by code we just need to create a new class extending Scene:

1. Create a new class in your Evergine project (MyScene.cs for example).
2. Make that class inherit from 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 start updating and drawing.
End()	Ends the scene
Pause()	Called when the scene is paused. It can be due the app being suspended or either manually paused through the ScrenContextManager.
Resume()	Resume the Scene when it's dead..

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);
    }
}
