Adobe Flash CS3 Classroom in a Book

Lesson 4: Working with Text

Lesson 4 uses an animated birthday card project to

introduce students to creating, formatting, and animat-

ing text in Flash CS3. Students work further with key-

frames, masks, and layers, and are introduced to ﬁlters.

Organizing layers in a Timeline

Layers are displayed on the Stage in the order in which

they appear in the Timeline, with the bottom layer

appearing ﬁrst in the stack, the next layer up appear-

ing on top of it, and so on, until the top layer in the

Timeline is also the top layer on the Stage. As designers

plan projects, they consider the order in which they

want objects to appear. For complex projects, it’s good

practice to create layer folders and think through the

order of the layers you want to use, rather than creating

layers on the ﬂy.

It is customary to create an Actions layer in Flash to

contain all of the ActionScript for the Timeline, and

to place the Actions layer at the top of the Timeline so

that it is easy for the designer or others to ﬁnd and ac-

cess to troubleshoot or revise the ActionScript.

Adding a sound le

To add an audio ﬁle to a frame in Flash, ﬁrst import it

to the library. Then, select the frame at which you want

the audio ﬁle to begin playing, and, in the Property

inspector, choose the audio ﬁle from the Sound menu.

Selecting the appropriate option from the Sync pop-up

menu is important. If a sound ﬁle doesn’t play when

you think it should, check the Sync menu to ensure

you’ve selected the right option.

• Event synchronizes the sound to the occurrence of

an event, such as a button click. An event sound plays

when its ﬁrst keyframe appears and plays in its entirety,

even if the SWF ﬁle stops playing. If another event oc-

curs, the ﬁrst instance of the sound continues playing

while the second instance of the sound plays.

• Start synchronizes the sound to the occurrence of an

event, just as the Event option. However, if the sound is

already playing, no new instance of the sound plays.

• Stop silences the speciﬁed sound.

• Stream synchronizes the sound for playing on a web-

site. Flash forces animation to keep pace with stream

sounds. If it can’t draw animation frames quickly

enough to keep up with the sound ﬁle, it skips frames.

Stream sounds stop if the SWF ﬁle stops playing.

Next to the Sync menu is a pop-up menu that deter-

mines who many times the sound ﬁle plays.

• Repeat speciﬁes the number of times the ﬁle plays;

specify a number.

• Loop repeats the sound continuously.

Note: Repeating stream sounds is not recommended,

because frames are added to the ﬁle and the ﬁle size is

increased by the number of times the sound is repeat-

ed. You can also apply effects to the sound ﬁle.

• None applies no effect

• Left Channel/Right Channel plays sound in the left

or right channel only.

• Fade Left To Right/ Fade Right To Left shifts the

sound from one channel to the other.

• Fade In gradually increases the volume of a sound

over its duration.

• Fade Out gradually decreases the volume of a sound

over its duration.

• Custom lets you create custom in and out points of

sound using Edit Envelope

Using tweens to animate objects

Motion tweens can animate the movement of elements

on the Stage, as in the case of the bubble in Lesson 1,

but they can also animate the change of objects’ prop-

erties, such as brightness or transparency.

Point out to students that an arrow appears in the

Timeline after you apply a tween to frames.

Creating text in Flash

Creating text in Flash is similar to creating text in

Adobe InDesign, Adobe Photoshop, or numerous other

applications. Use the Text tool to create an insertion

point on the Stage and begin typing, or drag the Text

tool to create a text box for your text. To format text,

select it with the Text tool, and then select formatting

options in the Property inspector. To manipulate a text

box as an object, select it with the Selection tool and
