The HideShow NBA

This is a nice little button action that HyperStudio has that allows objects to appear or disappear at the click of a button. 

Things to remember: 

• The object must be on the card.
• A button activates the HideShow NBA.
• Your object needs to have a name.
• If you want your button to show an object, hide it first.

Here's how to do it:

• Open HyperStudio and create a few cards.  Save the stack.
• Add an object to the card.  Name the object when prompted to do so.  Don't leave it as "Untitled" as you see below!

• Click on OK and add a button and place it on the card next to the object you want to hide. 

• After you click outside the button, you'll see the Actions window.  Choose NBA,.  In the Button Actions window, select HideShw2 NBA.

• You need to select "Use this NBA" after you select HideShw2 NBA..
• A new window pops up. 

• Enter the name of your object.
• Click on the radio button that is next to "Graphic" and then the button next to "Hide it" in the "What should I do to it?" option. 
• Hit OK a few times and Done and you'll be back to your card.
• Select the Browse Hand and click on the button.  Your object disappears.
• You can also do something like this to get the object to reappear:

 The "Flip" option is a good one to use if you want the button to do both actions sequentially.  Regardless, there's a lot to this HideShow NBA that Vygotsky would want you to discover.  Go for it!

Here's a nice way to use this NBA with a table of contents.

Each number is a button that "Shows" the next topic.  Nice font, too.
