Flash CS3-AS3. In order to get my movie to preload correctly… I unchecked ‘Export in first frame’ on all my game elements, and set my export frame to 2 in publish settings.

I get this error…

ReferenceError: Error #1065: Variable defaultGameTile is not defined.  
at global/flash.utils::getDefinitionByName()  
at farmGame\_fla::MainTimeline/addTile()

```auto

function addTile(i, cellX, cellY, tileType) {
    var newTile = new (getDefinitionByName(tileType))();
    game.addChild(newTile);
}

```

If I check ‘Export in first frame’, the error goes away… What gives? My game is on frame 2, I even tried frame 3…

Edit: Tried creating a class to make sure it wasn’t a problem with flash not generating classes. Didn’t help. 😕 Is it a problem with getDefinitionByName needing stuff to be exported in first frame???

This technote didn’t help… My movie doesn’t skip the export frame.

Why are my classes missing unless they are exported in first frame… ahhhhhhhhhhhh Ahhhhh! _tears hair out_

Note: I even set the publish setting to export in frame 1 and my classes are missing, however if the box is checked on the movieclip in the library… They work??? Wtf…
