Is there a way of adding text on top of a vector graphic instead of using a standard button in Director? My intention is to attach words to a button designed as a vector graphic. Something like adding the words "Click Here" to the button.
You could place a text sprite in the next higher channel than the vectorShape sprite in the score. Or you could use imaging lingo to combine the vectorShape member's image and the text member's image into a bitmap member.
Also is there a tutorial on the net to show how to design three interactive buttons that change when the cursor is entering or clicking on them or can this only be done through a behaviour?
It is readily done in the Director environment using a behavior/script. If you want to use Flash to create (and import) buttons from there, such buttons can be created in Flash without using code and don't require any code in Director to display their various states.
The Library Palette has a number of button type behaviors - such as:
In 'Interactive > Animation' category
Rollover Cursor Change - as the name suggests, changes the cursor
Rollover Member Change - switchescast members of a sorite, one when the mouse is over, the other whne it is off the sprite
The above give a few more states than available in the 'Rollover Member Change' behavior.
Experiment with the behaviors in the library. There are some good ones in there. And they are teh easiest way to get this type of effect (as compared to writing the code yourself).
