Now that you've got your picture... Now you're ready to start your Flash movie. At this point your natural
urge will be to make a new movie clip and immediately importing the huge
image file that you just created. Don't do it. Flash isn't particularly
fond of objects as large as your picture most likely will be. You'll find
that if you try to import it and manipulate it very much, Flash will crash.
Therefore, it's a better idea to make your movie and set up all your code
before placing your image.
Step 1: Understanding how the
darn thing works.
The concept behind an agileVR really isn't very complicated. There are
two identical movie clips that contain the image. There is an invisible
button that detects when the viewer presses the mouse button. There is
an invisible movie clip being dragged that supplies the mouse's current
position. When the user presses his/her mouse button, the invisible button
sets two variables according to the x-value of the mouse at the instant
the button was pressed (it gets these from the invisible dragging movie).
It also tells another invisible movie clip to play. This second movie
clip takes the initial mouse coordinates and compares them to the current
position of the mouse. From this simple calculation, the movie clip comes
up with an x-offset for the image movies. The movie clip then updates
the position of both image movie clips by that values, checks if one of
the movies is too far off of the screen, and then loops. Frame one of
the update clip has a stop for when the user does not have his/her mouse
button pressed. The second and third frame contain the actual code that
makes the movie pan. The code in the third frame of my update movie looks
something like this:
Begin Tell Target ("../")
Set Variable: "x" = GetProperty("/hidden", _x)
Set Variable: "offset_x" = (start_x - x) / 8
Set Variable: "cur_x1" = GetProperty("/movie1", _x)
Set Variable: "cur_x2" = GetProperty("/movie2", _x)
Set Property ("/movie1", X Position) = cur_x1 + offset_x
Set Property ("/movie2", X Position) = cur_x2 + offset_x
End Tell Target
Go to and Play (2)
Frame two checks to see if either
image movie is far enough the screen that it can be situated on the
opposite side. This makes it look like the image is one continuous picture.
