Class Layer

Example

    // Put several scene objects on the same Layer as an orthographic camera so
    // that camera renders them. A SceneObject is only drawn by a camera when
    // their layer sets intersect — make sure the target camera's renderLayer
    // includes the layer used here, otherwise the objects will not be visible.
    const model = this.pluginSystem.findInterface(Editor.Model.IModel) as Editor.Model.IModel;
    const scene = model.project.scene;

    // Orthographic camera. Its renderLayer starts at the default set that
    // covers Editor.Model.LayerId.Default.
    const camObj = scene.createSceneObject('OrthoCamera');
    const camera = camObj.addComponent('Camera') as Editor.Components.Camera;
    camera.cameraType = Editor.Components.CameraType.Orthographic;

    // Build a matching LayerSet from the id the camera uses, then assign it
    // to each new object so the ortho camera will include them in rendering.
    const layerId = Editor.Model.LayerId.Default;
    const targetSet = Editor.Model.LayerSet.fromId(layerId);
    camera.renderLayer = targetSet;

    const objects = [
      scene.createSceneObject('UiPanel'),
      scene.createSceneObject('UiButton'),
      scene.createSceneObject('UiLabel'),
    ];
    for (const o of objects) {
      o.layers = targetSet;
    }
    console.log(`Placed ${objects.length} objects on the same layer as the ortho camera.`);
