- Prerequisites
- Flash CS3 desktop tutorial. It's probably a good idea to use a layout similar to the ones I suggest there.
- You also may first look at the first part of the Flash drawing tutorial.
- Next steps

- Quality and level
- This text should technical people get going. It's probably not good enough for beginners, but may be used as handout in "hands-on" class. That is what Daniel K. Schneider made it for...
- It aims at beginners. More advanced features and tricks are not explained here.
Introduction
Layers help you deal with items for more complex documents. Working with layers has several advantages:
- You can draw and edit objects on one layer without affecting objects in another layer.
- You can lock layers (to protect these and its objects from editing)
- You can hide layers, make them visible (i.e. you can see and manipulate its objects in the workspace), or you can display just the outlines of its objects.
The layers tool is part of the Timeline panel.
Overview picture
The layers tool is in the left part of the timeline. Annotations in the following screen capture highlight a few functionalities we will further explain below.
Drawing in a layer
To draw, paint, or otherwise modify a layer simple click on the the layer name in the Timeline to make it active. A pencil icon next to it indicates that the layer is active.
Creating new layers and deleting layers
When you create a Flash document, it only contains a single layer, i.e. less than you need.
To create a new layer, either:
- Insert->Timeline->Layer
- Click on layer icon (left most item in the Edit bar just below the timeline)
As soon as you create a new layer, you should give it meaningful name. Right-click on its name (something like Layer 2) select Properties and change the name. Alternatively, to display the properties panel, just double-click on the layer name.
To delete a layer and its contents: Right-click->Delete Layer. You also can lock/hide other layers with this menu. Before you delete a layer make sure that save its objects if you plan to keep them. You can them in the library as symbols or copy them to another layer.
Show only outlines of a layer
- Click on the rectangle next to the layer name. If this rectangle turns empty then you only should see outlines of its objects.
- You also can change the outline color by double-clicking on the rectangle. E.g. if your background is green (like in our example), the outline should be of a different color (it's not really in our case).
Lock and hide layers
Click on the dots below the appropriate hide/lock/display icons in the panel to apply locking/hiding/displaying to a single layer, or on the icons themselves to apply an operation to all layers (e.g. lock all).
TIP: Always lock all layers and then just unlock the layer on which you are working. This way you can prevent yourself from making mistakes.
Moving layers
To move a layer in the stack simply grab it with the mouse and drag it up or down. Position of the layer has an influence on the order objects are drawn. This depends on the load order defined in the Publish Settings (File menu)
Example
The following screen capture shows hidden and locked layers:
- The painting layer is active (the pencil is shown)
- The objects layer only shows outlines and in addition its locked (lock sign is on and rectangle is empty. Its objects are drawn in light green, i.e. the color of the rectangle)
- The Sky layer is hidden (The X sign is on).
Layer folders
Once your documents get really complex, you can organize layers into folders, e.g. one folder per task: Static objects, animations, background etc.
To create layer folders, either:
- click on the folder icon in the Edit bar (third item)
- or use Insert->Timeline->Layer Folder
You then can drag around layers. Hiding, locking etc. works more or less like with folders (try it out ...)
Scenes
Once you animation gets bigger, you most certainly can break it down to several scenes. There is no urgency to work with scenes if you are new to Flash, but you should know about this now. Scenes are played in the order you defined them.
- To insert a new scene
- Menu Insert->Scene
- To rename/reorder the scenes
- Menu Window->Other Panels->Scene (SHIFT-F2)
- Then drag up or down the scenes
- To rename, double-click on a scene name in this panel.
- To navigate between scenes
- Either via the scenes panel, or the Edit Bar (displayed below the timeline). If you can't see it: Window->Toolbars->Edit Bar.
One advantage of using scenes is that you can just test the scene (menu Control->Test->Scene).
