You can use Layer properties to adjust the appearance and functionality of a Layer component.
Adjusting Layer Properties
Select the corresponding Layer component in the Scene Manager and go to the Layer section located under the Properties tab in the Inspector. You can type a value into the corresponding field, or select a value from a list.
Background Image: Select an image for the background of the layer. To find a particular item from a large list, you can also start typing the name of the item into the field.
Exclusive: Set this option to make this layer exclusive in its visual appearance. All other sibling layers, i.e. layers that have the exact same parent component, will be hidden when this layer is made visible. This applies only to sibling layers that also have the Exclusive option activated.
Note: Making a layer invisible won't automatically render any other layer visible.
Working with Layer Properties
Focusing the attention of your audience on one particular object may increase the effect of your content. Using the Exclusive property makes it easy to hide other layers, saving you from the need to create a large number of actions in order to hide and show various objects.
However, in the planning phase of your scenario you need to invest some time to create a scene structure that works as desired. For instance, picture a scenario with three layers, of which one is to be shown at a time. You can't control all layers with just one object, e.g. a button. You need one button for each layer.
Place three buttons in your scenario, each of one handling a different layer. Place all buttons at the same spot to give the impression of one button. On a touch, have the foremost button make the corresponding layer visible with one action, and have another button brought to the front with another action.
The next touch would hit another button, which would make another layer visible and bring the third button to front. This way you could cycle through the layers with apparently just one button. To have this scenario work, do not forget to let your buttons consume incoming touch events.
