The Layers Bar is used to add, edit and remove layers in a layout. A layer is like a sheet of glass objects are painted on to. This allows easy arrangement of which objects display in front of other objects, for example showing foreground objects in front of the background sprites. It also allows for interesting depth effects like Z elevation or parallax, and layers can be individually scaled and rotated as well.
Layers can be dragged and dropped in the Layers Bar to change their order. Layers at the bottom of the list are displayed at the back (e.g. background objects), and layers at the top of the list are displayed at the front (e.g. HUD objects).
Selecting a layer displays its properties in the Properties Bar and also sets it as the active layer which new objects are inserted in to.
Each layer in the list has the following:
You can right click a layer to see a menu of additional options, such as to add a new layer, rename or delete layers, or shortcuts to show, hide, lock or unlock all layers (or all but the selected one). Layers which are showing content from a global layer will show a context menu option to go to the layout where the original global layer is in.
Layers can also be added as sub-layers of another layer. They can be added as sub-layers or moved to be sub-layers via drag-and-drop. Sub-layers appear indented in the Layers Bar to show they come under another layer, and the layer they belong to can be expanded or collapsed to show or hide all its sub-layers.
Sub-layers can be used solely to help organize long layer lists, acting like layer folders. However applying an effect to a layer will also affect all its sub-layers. This allows for more efficiently processing effects (instead of having to add the same effect repeatedly to several layers), as well as more advanced effect composition across different groups of layers.
To modify the Z order (front-to-back order) of individual objects on a layer, use the Z Order Bar Paid plans only.
