Step 1 – Overall Navigation Layout and Organize Assets
Decide on Overall Navigation Layout
1) Create layers for "background", "navigation", "stage" ...
2) Create Guides for Navigation Text and Images
Import Images for Navigation
1) Resize to fit allocated space (or "create to spec" in image editing program).
2) Convert images into Graphic Symbols.
Organize Assets
1) Open "Library" window.
2) Click on "Folder" icon to create folders for "Images", "Buttons" ...

Step 2 – Create Animations for Navigation Buttons
1) Create "Movie" symbol using "Insert > New Symbol".
2) Drag "Graphic Symbol“ onto Stage of Animation (creates instance)
3) Add keyframes.
4) For each keyframe, apply effects (select instance on stage to apply Alpha effect).
5) Animate by applying "tweening"
6) Select last keyframe, open "Actions" window (can use Right-Click) and type "stop ();" (so that the animation does loop).
Make sure "Frame" is selected by checking "Actions for ..." the heading in top left corner.

Step 3 – Create "UP" Buttons
1) Insert "Button" symbol.
2) Create layers and guides for text and animation.
3) "UP" state - create text (and possibly background shape)
4) "OVER" state - insert keyframe, modify text, add animation.
5) "DOWN state - insert (empty) keyframe, modify text and add static graphic by selecting animation and using "Swap" in the Property Inspector; want graphic to line up with end state of animation.
6) "HIT" state - define "hotspot" for button (in addition to shapes in other states).

Step 4 – Create "Down" Buttons
Use "Duplicate Symbol" to Create Buttons
1) Select "Button" symbol, Right-Click, select "Duplicate" and name it.
2) Replace text in the keyframes for the different states.
3) Use "Swap" to replace animation and position appropriately.
Create "Down" Buttons
1) Use "Duplicate Symbol" to create "Down" button and name it.
2) Update states: "down" and "up" become identical (use "Copy Frames" and extra layer for swapping if needed).
3) "Over" should also contain static image as in "Up" state and the same text color as in "Up" state.

Step 5 – Make Button Instance Interactive
Open "Scene" Window
1) "Scene 1" - name it "Bilbao".
Make Button Instance Interactive
1) Select instance of button in "Scene 1" and name it
2) Open "Action" window.
3) Press "+" and then select action to be triggered:
Global Functions > Timeline Control
6) Select "gotoAndStop" and for scene select "Bilbao".
Action associated with button is:
on (release) {
gotoAndStop ("Bilbao", 1);
}
© Anselm Spoerri
Step 6 – Make Button Instance Interactive (cont.)
Select ActionScript for "Bilbao" Button
1) Select instance of "Bilbao" button and open Actions Window
2) Select ActionScript and copy it
Select Button Instance
1) Select instance of button (and name it).
2) Open "Action" window
3) Paste ActionScript.
4) Modify "gotoAndStop ("Bilbao", 1) so that another scene (to be created) is referenced, such as "Gehry", "Meret" or "Dance".
Action associated with button is:
on (release) {
gotoAndStop ("SceneName", 1);
}

Step 7 – Create Scenes and Swap in “Down” Button
Create "actions" Layer
1) Insert layer called "actions".
2) Select first keyframe and open "Actions" window.
3) Type "stop ();".
Open "Scene" Window to Duplicate Scenes
1) Open "Scene" window.
2) Click the "Duplicate Scene" icon in the bottom right.
3) Name the duplicate consistent with scenes referenced in the ActionScripts associated with the different buttons.
Insert "Down" Button for Each Scene
1) Select button related to selected scene.
2) Use "Swap" in Property Inspector and select "Down" button.

Attach ActionScript
• Frame stop (); Function definitions Variables
• Button
• Movie Clip
Actions panel allows you to select, drag and drop, rearrange, and delete actions
Reference panel to view detailed descriptions of actions Window > Reference
Flash can detect what action you are entering and display code hint
Scripts attached to a frame execute when playhead enters frame. – first frame in a movie is rendered incrementally
Scripts attached to movie clips / buttons execute when event occurs

ActionScript Terminology
Objects are collections of properties and methods
Methods are functions assigned to an object
Instances are objects that belong to a certain class
Instance names are unique names that allow you to target movie clip instances in scripts Use Property inspector to assign instance names to instances on Stage.
“this” to movie clips
Target Paths = Hierarchical Addresses movie clip instance names, variables, objects in movie
– Use target path to direct action at a movie clip or to get or set variable value
_root.stereoControl.volume
© Anselm Spoerri
Dot Syntax “.”
Indicate the properties or methods related to an object or movie clip
Used to identify target path to a movie clip, variable, function, or object
movieClip._x
movieClip._alpha
movieClip._xscale
movieClip._visible = true;
_parent.movieClip.play ();

Defining a Function
// global
_global.myFunction = function (x) {
return (x*2)+3;
}
// local
function sqr(x) {
return x * x;
}
© Anselm Spoerri
MovieClip – Event Handler Actions and Methods
Event handler actions Event handler methods
onClipEvent (load) onLoad
onClipEvent (enterFrame) onEnterFrame
onClipEvent (mouseDown) onMouseDown
onClipEvent (mouseUp) onMouseUp
onClipEvent (mouseMove) onMouseMove
onClipEvent (keyDown) onKeyDown
onClipEvent (keyUp) onKeyUp
onPress onRelease
onRollOver onRollOut

Step 1 – Create Global Function
Insert Layer “functions” in first scene “Bilbao” to contain global functions
Want to create function that changes transparency and scale of movie
1) Open Actions Window
2) Enter function definition
_global.changeVisuals = function (movieClip, alpha, scale) {
movieClip._alpha = alpha;
movieClip._xscale = scale;
movieClip._yscale = scale;
}

Step 2a – Create Secondary Navigation Buttons Using ActionScript
1) Create “Movie” Symbol = “Furcup Button”
2) Create Button Background and Text
3) Create Secondary Navigation Area in “Meret” Scene
4) Add instance of “Furcup Button” movie clip to “Meret” scene and name it “Furcup”
5) Select “Furcup” instance
6) Open Actions window
© Anselm Spoerri
Step 2b – Create Secondary Navigation Buttons Using ActionScript
With “Furcup” movie clip instance selected, add in Actions Window
onClipEvent (load) {
var alphaOut = 50;
var alphaOver = 75;
var alphaPress = 100;
var scaleOut = 100;
var scaleOver = 110;
var scalePress = scaleOver;
// set transparency
this._alpha = alphaOut;
this.onRollOver = function () {
trace ("Over");
changeVisuals (this, alphaOver, scaleOver);
}
}
© Anselm Spoerri
Step 2c – Create Secondary Navigation Buttons Using ActionScript
onClipEvent (load) {var alphaOut = 50;
var alphaOver = 75;
var alphaPress = 100;
var scaleOut = 100;
var scaleOver = 110;
var scalePress = scaleOver;
// set transparency
this._alpha = alphaOut;
this.onRollOver = function () {
trace ("Over");
changeVisuals (this, alphaOver, scaleOver);
}
this.onRollOut = function () {
trace ("Out");
changeVisuals (this, alphaOut, scaleOut);
}
this.onPress = function () {
trace ("Press");
changeVisuals (this, alphaPress, scalePress);
_parent.gotoAndStop("Furcup");
}}

Step 3a – Label Keyframe, Create “DOWN” Button
1) Create layer = “labelled”
2) Select frame = 20, Insert Keyframe and Name it “Furcup”
3) Add “stop ();” to “actions” layer at frame = 20(need to add insert keyframe)
3) Insert Keyframe at frame = 20 in layer “furcup”
4) Select instance of movie clip and name it “FurcupDown”
© Anselm Spoerri
Step 3b – Modify attached ActionScript
Modify ActionScript attached to “FurcupDown” instance
var scalePress = 120;
this._alpha = alphaPress;
this._xscale = scaleOver;
this._yscale = scaleOver;
this.onRollOver = function () {
trace ("Over");
changeVisuals (this, alphaPress, scaleOver);
}
this.onRollOut = function () {
trace ("Out");
changeVisuals (this, alphaPress, scaleOut);
}
this.onPress = function () {
trace ("Press");
changeVisuals (this, alphaPress, scalePress);
_parent.gotoAndStop("Furcup");
}

Step 4a – Create “Disjointed” Rollover
Create “Furcup Animation”
1) Import “Furcup” image and convert to Graphic Symbol
2) Create new movie clip symbol called “Furcup Animation”
3) Create Animation (make sure image expands from origin of movie clip).
4) Add instance “Furcup Animation” to “Meret” scene at frame = “Furcup”
5) Name instance “FurcupImage”
Create “Furcup Text"
1) Create new movie clip symbol called “Furcup Text”
2) Create Text
3) Add instance “Furcup Text” to “Meret” scene at frame = “Furcup”
5) Name instance “FurcupText”
© Anselm Spoerri
Step 4b – Create “Disjointed” Rollover
Make “FurcupText” Invisible
1) Select “actions” layer at frame = 20
2) Add ActionScript
FurcupText._visible = false;
© Anselm Spoerri
Step 4c – Create “Disjointed” Rollover
Add “Disjointed Rollover” to “FurcupImage”
Select “FurcupImage” instance and in Actions window
onClipEvent (load) {
this.onRollOver = function () {
trace ("Over");
_parent.FurcupText._visible = true;
}
this.onRollOut = function () {
trace ("Out");
_parent.FurcupText._visible = false;
}
this.onPress = function () {
trace ("Press");
}
}
