Work with stacks and layers

You can use layers to group objects that you want to show or hide together. As long as a stack is visible, its base layer will also remain visible.

Stack with Base Layer Highlighted

By default, layers within the same stack are displayed one-at-a-time (except the base, which is always visible), i.e., if you create an action to show a layer, the other layers will be automatically hidden. This also means that when you show a layer, you don’t need to create a separate action to hide the other layers.

By default, only one layer will show at a time

If you want multiple layers to show at the same time, select the Stack and change the Layer Behavior property to Unrestricted.

  2. Select Copy Copy Button .

To paste the stack onto the current page:

  2. Right-click on the stage, or on any stack in the Cast.
  3. Click Paste Paste Button .

Select a layer

Note When you select a layer, the list of objects in the layer will expand. To collapse this list, click the selected layer again.

Show or hide a layer (while authoring)

To hide a layer:

To show a layer that is hidden:

Note Except for the Base layer, layers are set by default to show one at a time, i.e., whenever you select one layer, the others will be automatically hidden. To change this, see Show more than one layer at the same time

Show more than one layer at the same time

Layers are set by default to show one at a time, i.e., whenever you show one layer, the others will be automatically hidden. This applies both to how they are displayed while authoring, and at run-time. If you want to show more than one layer at once, you must change the Layer Behavior to Unrestricted.

  1. Select the layer, or the stack that contains the layer, that you want to change.
  2. In the Properties tab, click the dropdown menu next to Layer Behavior, and then click Unrestricted.
    Layer Bahavior Properties

Note Changing the Layer Behavior will affect ALL layers in the stack. To have some layers appear one at a time while others remain visible, place the two types of layers into separate stacks.

Show the next or previous layer while authoring

Move an object from one layer to another

To move an object by dragging it:

Note If you drop the object onto the layer name, it will be moved to the top of that layer. If you hover over the layer name while dragging, the list of objects will expand, and then you can drag the object you are moving to the desired position.

To move an object using Cut and Paste:

  1. In the Cast, right-click the object you want to move, and then click Cut.
  2. Right-click the layer you want to which you want to move the object, and then click Paste.
