VR Panoramas > Director/Shockwave

Another level of interaction can be experienced when you roll the mouse over a hotspot. When you click on a hotspot you could, for example, display an information box when a hotspot is clicked on. Here's a very simple example - click on a hotspot and it will tell you what it's ID number is (if you know the ID number of hotspots in a scene you could perhaps start to build "information points" around them - or maybe create a puzzle where the user needs to click on the hotspots in order...).

Here's how you'd go about the process in Director:

• Step 1

Select the QTVR sprite on the score and then select New Behavior from
the Behavior drop down menu in the score

Delete any existing script and type the following (the text can be
copied and pasted into the Behavior script window):

property p_currentSprite --The BeginSprite handler is called when the QTVR sprite first appears -- on stage. It determines the channel that the sprite is residing in and -- then sets up the handler - HotSpotCallback - to be called when a user -- clicks on a hotspot on BeginSprite me set p_currentSprite = the SpriteNum of me set the triggerCallback of sprite p_currentSprite = #HotSpotCallback end -- The HotSpotCallback handler simply alerts the ID of the hotspot -- clicked on on HotSpotCallback me, theHotSpotID alert "The ID of the HotSpot clicked on is " & theHotSpotID end --The EndSprite handler is called when the playback head enters a frame -- where the QTVR sprite is absent. It clears the triggerCallback -- property on EndSprite me set the triggerCallback of sprite p_currentSprite = 0 end

• Step 2

Close the script window, rewind and run the Director movie. Click on
a hotspot in the QTVR movie

• Step 3

The HotSpotCallback handler can be easily changed to include
specific testing for individual hot spots. This can be achieved through
the use of if...then or case statements.

on HotSpotCallback me, theHotSpotID if theHotSpotID =100 then alert "That's right!" else alert "Sorry, try again" end if end

It's up to you to decide what you'd like to do with this feature, but it has a lot of potential!
