Graphic Movie clip Button
See http://cartoonsolutions.com/store/catalog/Symbol-Types-sp-75.html for a good explanation of the difference between a movie clip and a graphic symbol.
For static images or animations that are tied to the main timeline.
Synchronized with the main timeline. The main timeline must have enough frames to hold the number of frames in the graphic symbol’s timeline (from the point in the main timeline where the graphic symbol is inserted).
Interactive controls and sounds won’t work in a graphic symbol’s animation sequence.
Add less to the FLA file size than buttons or movie clips because they have no timeline.
Has its own timeline that is independent from the main timeline Can be given an instance name so that it can be referred to and
manipulated through ActionScript Can be dynamically allocated through ActionScript
Create the movie clip so that it’s in the library When you create the movie clip, check the “Export for ActionScript” box Dynamically create an instance of the movie clip with a call to new. For
example: var clown:MovieClip = new Face(); clown.x = 200; clown.y = 200; clown.width = 200; clown.height = 200; addChild(clown);
See the example on the course blog.
Interactive object that responds to mouse clicks, rollovers, or other actions.
You define the what the button looks like in the up, over, and down states
You define the “hit” area You add an ActionListener to indicate what
happens when the button is pressed. See the example on the course blog.
There are quite a few supported sound file types, including WAV, MP3, and AIFF.
Import with File/Import/Import to Library. Make a layer for the sound. Drag the sound from the Library to that layer. Set the option appropriately to Event, Start, Stop, or Stream.
Description of sound options: An Event sound synchronizes with an event. An event sound, such as a sound that plays
when a user clicks a button, plays when its starting keyframe first appears and plays in its entirety, even if the SWF file stops playing.
A Start sound is the same as Event, except that if the sound is already playing, no new instance of the sound plays.
Stop silences the specified sound. A Stream sound forces animation to keep pace with the sound. If Flash can’t draw
animation frames quickly enough, it skips frames. Unlike event sounds, stream sounds stop if the SWF file stops playing. Also, a stream sound can never play longer than the length of the frames it occupies.
See the course blog for examples.
You can create video if you want to. I have a couple of good video cameras you can borrow, including a new HD one.
Make a short clip, compress it as FLV or H.264, and put it into your Flash movie.
This tutorial shows you in a nutshell how to create a video to be played in the Flash player: http://tv.adobe.com/watch/learn-flash-professional-cs4/getting-started-10-working-with-video/
