See how to create changing text position animation on a very quick way in flash, using the action script code. You can use this animation for some presentation, as flash banner, flash header... This lesson is so easy for create, but in the same time very practical. Let's go!
Step 1Create a new flash document. Take the Text Tool (A) and type some text.

Step 2While the text is still selected, press F8 key (Convert to Symbol) to convert this text into a Movie Clip Symbol.
Step 3While the new made Movie Clip (text) is still selected, go to the Action Script Panel (F9) below the stage and enter the following action script code inside the actions panel:
onClipEvent(enterFrame)
{
_alpha=random(90);
_x=_x=random(300);
_y=_y=random(225);
}
Step 4Take the Selection Tool (V), select the text, and press few times Ctrl+D key (Duplicate) to duplicate this text few times. After that, place it all around. See the picture below.

Test your Movie (Ctrl+Enter).
We're done!
Enjoy!
