Here is a simple infinite rotation script (based on Leslie's script):

point3 $a;
float $speed;

$a = (0, 1, 0); /* Replace with the desired rotation axis */
$speed = 5; /* Replace with the desired speed */

$a = normalize($a);
$orientation = ($a.x*sin($speed*time), $a.y*sin($speed*time), $a.z*sin($speed*time), cos($speed*time));

I'm sorry for not replying, I had no internet access in the past several days...

I agree with Hiho, using Cre8or for physics is ok.

I hope to see some entries soon!

Hi Bob,

I found a simple example for you. I created this script several years ago, it never proved to be useful, but it's simple enough to be used as a learning source. It's called "Grow Points Selection" - it finds all selected points and selects all their neighbours.

#command("object");

shape $Shapes[0], $S;
int $i, $j, $SelectedPts[0];

/* Find all the shapes in the current object and store them in the $Shapes array */
project.curObject.GetShapes($Shapes);

/* Loop through all the shapes */
while ($Shapes.size > 0) {

  /* Remove the last item from the array */
  $S = $Shapes.pop();

  /* Continue only if the current shape is a mesh */
  if ($S.GetKind() == SHAPE_KIND_MESH) {

    $SelectedPts.size = 0;

    /* Loop through all points of this shape */
    for $i = 0 to $S.GetNumPoints()-1 do {

      /* If the current point is selected, add it to the $SelectedPts array */
      if ($S.GetPointSelected($i))
        $SelectedPts.push($i);
    }


    /* Select all neighbour points of each point in the $SelectedPts array */
    for $i = 0 to $SelectedPts.size-1 do {

      for $j = 1 to $S.GetNumEdges() do {

        if ($S.GetEdgeIndex0($j) == $SelectedPts[$i])
          $S.SetPointSelected($S.GetEdgeIndex1($j), true);

        else if ($S.GetEdgeIndex1($j) == $SelectedPts[$i])
          $S.SetPointSelected($S.GetEdgeIndex0($j), true);
      }
    }
  }
}
I tried to provide enough comments, if you have any questions I'll be happy to help you.

As for your questions... The pop and push functions are used to remove/add array items, as you can see from the example above. ASL arrays do not have a fixed size so you can always remove the last item by calling the pop() function or you can add a new item to the end of the array by calling the push() function.

The Marked property and SetXXXMarked() and GetXXXMarked() functions are something I've never used... Anyway, you can make any shape, texture, edge, face etc. "marked" or "unmarked" just like you can make certain components selected/unselected. The difference is that making things marked does not make them look differently, it's just an internal property you can use. It might be useful in very complex scripts where you need to keep track of many things...

Command scripts are not much different than parametric scripts or export scripts... The only difference is that you have a few extra functions available while some features (such as user input) are more restricted. As always, the ASL specification is your best friend

Haha, I love your video Josmic8or! Great job, the music is perfect and the animation is very well done!

Awesome work Daniel! The model seems to be very clean and the texture looks very realistic.

Hey $imon, your porktrait is really hilarious, lol ROFL I couldn't stop laughing ... Huh... Ok, seriously now, you should stop using those magic mushrooms Anyway, the thing looks to me like an EMO pig, don't know why Nice model though.

I should start working on my entry, I still have 3 days left...

I've already seen this error message... It basically means that Anim8or is unable to write data to the avi file because the file is being used by another process.

It usually happens when you abort the render (or when the renderer crashes) and then you retry rendering using the same file name. There is probably a bug in Anim8or, the program still thinks the .avi file is in use although the original rendering session is over.

Using a different file name should help...

Also keep in mind that re-starting the computer solves 90% of all problems

As far as I know, Anim8or simply displays all codecs available on your computer. You can install and un-install most codecs just like any other software...

The way codecs work should not be much related to Anim8or - some codecs produce reasonable quality and file size, other codecs are simply useless, but it all depends on the settings and codec versions... Also keep in mind that the same codec that was used in production must be available to play the video. Therefore it's only reasonable to use the most common codecs. Like Kreator said, you should try XVid and DivX, these two codecs are quite common and produce a reasonable image quality.

However the best you can do IMO is to avoid all .avi codecs completely. I usually export my videos uncompressed or as a series of .bmp images to get the best possible quality before the post-production starts. When I have my final video done, I decide which format/codec to use...

There are 3 most common file formats for videos - AVI, MPEG and WMV. Most video-editing applications support all of them plus many more (only .avi is supported by Anim8or though). As written above, the .avi format causes problems with codec compatibility. MPEG is a bit better from this point of view, but I also had some problems with .mpg videos... My favorite format is .wmv, mainly because the file size/quality ratio is IMO the best. Although it's a proprietary format developed by Microsoft, it is possible to play .wmv videos on most platforms (using the right program) and I've never had problems with compatibility, codecs, versions etc... WMV videos can also be easily optimized for internet streaming. The only disadvantage is that you need to use a third-party video editing software since WMV is not supported by Anim8or directly. But like you said, even Movie Maker can do the conversion so this shouldn't be a problem.
