The Routine

Now comes the real part: the engine program itself.

First we are going to create the initiation routine, the one that starts it all out. Open the second key-frame of the actions layer. This is what we do:

• move the baseline instance so that no one can see it on the picture.
`Set Property ("/baseline", X Position) = "1000"`
• then let's cut the points variable up into lots of separate coordinate variables:
```Set Variable: "n" = "1"
Loop While (n <= totalpoints)
Set Variable: "x"&n = Substring (points,( (n-1) * 12 + 1), 3 )
Set Variable: "y"&n = Substring (points, ((n-1 ) * 12 + 5), 3 )
Set Variable: "z"&n = Substring (points, ((n-1) * 12 + 9), 3 )
Set Variable: "n" = n+1
End Loop```
This places the x-coordinate of point 1 in variable x1, the y-coordinate in y1, the z in z1 and the same thing for all other points.
• now we do the same thing for the lines variable:
```Set Variable: "n" = "1"
Loop While (n <=totallines)
Set Variable: "pt1"&n = Substring (lines, (n-1)*5+1, 2 )
Set Variable: "pt2"&n = Substring (lines, (n-1)*5+3, 2 )
Set Variable: "n" = n+1
End Loop```
The first end of point 1 is put in pt11, the second one in pt21, etc.
• set the center of the display. These are the coordinates of point (0,0) in the movie.
```Set Variable: "centerx" = "190"
Set Variable: "centery" = "215"```
That's all for the initial frame

» Description: Hmm... what to say about this one? It's reminiscent of the closing notes of the opening music from the Three Stooges done in a church organ style with a closing cymbal crash. I'll give this one away gratis, but feel free to check out my free loops and potential upcoming license-mandated ones over in the respective part of Flashkit.
