ah… but that doesn’t solve your problem. The point of not using a button to do this is that if you want to use your cursor to actually click on a button, they will interfier with the button that controls visibility.
That is to say, if you place buttons above the button that controls the visible state, then everytime you roll onto one of those buttons it will be rolling off of the large underlying button making your cursor invisible. If you place those buttons under the main button then you’ll never be able to click on them.
By using the above method, we are illiminating the button entirely which free’s up your project to use other buttons.
As a second note, you want to avoid using alpha 0 objects if you can. Alpha levels are the largest hog of viewer processor power of any element used in a movie. If you really want to make an invisible button do this instead.
Create a square of fill. Color is irrelivant, but I usually use a bright green color.
Select the square, and hit F8. Select button, and give it a library name if you want to.
Now double click on this button in the library to open it for editing. You’ll see it’s four frames, “up” “over” “down” and “hit”. Click on frame 1 “up” and drag it until it is in frame 4 “hit”. Then release the mouse. You should see nothing in the first three frames.
Exit out of the editing of that button and you’ll see that the instance of the button on the stage has changed. Instead of being whatever color you chose, it is not transluscent blue. Do a test on the movie and you wont see the button at all. You will see the cursor change to the little hand if you roll over the button, but it is invisible because it has no states other than a hit state.
I use these types of invisible buttons for just about everything. One reason is, I only need to create the one button and I can use it over and over again as many times as I like. The user is only downloading a single button ever.
