Full Version: Getting the first tutorial to work with Flashout and mtasc.

I am trying to work through the tutorial using mtasc with Flashout under Eclipse.
I am on the second step - putting a box on the screen.

I have removed some white space and comments to shorten the post

CODE

class com.rwcontrols.sandytest.TestMain {
    static var app : TestMain;
        function TestMain() {
            var myMC : MovieClip
                try
                   {  _root.createEmptyMovieClip('myMC', 1)
                    init(_root.myMC); }
                catch (e:Error)
                    {trace(e.message);}
                   }

    // entry point
    static function main(mc) {app = new TestMain();    }

function init( stage : MovieClip  ):Void
{
   var ecran:ClipScreen = new ClipScreen( stage, 600, 600 );
   var cam:Camera3D = new Camera3D( 400, ecran);
   World3D.getInstance().addCamera( cam );
   var bg:Group = new Group();
   World3D.getInstance().setRootGroup( bg );
   createScene( bg );
}
static function createScene( bg:Group ):Void
{
    var o:Object3D = new Box( 50, 50, 50 );

    bg.addChild( o);
}

}
It compiiles quite nicely with no errors but does not draw a box on the screen

C:\mtasc\mtasc.exe  -swf C:\eclipse\workspace\sandytest\test.swf -cp C:\eclipse\workspace\sandytest\src -main com\rwcontrols\sandytest\testmain.as -trace Flashout.traceReplacer -header 800:600:20  -cp C:\mtasc\std8
..... compilation complete!

If I test
    try
    {  _root.createEmptyMovieClip('myMC', _root.getNextHighestDepth());
        _root.myMC.createTextField("tf",0,0,0,800,600);
        _root.myMC.tf.text = "Hello world !";
//       init(_root.myMC);
}
    catch (e:Error)
    {trace(e.message);}
    }
I do see "Hello World"

If I test
    try
    {  _root.createEmptyMovieClip('myMC', _root.getNextHighestDepth());
        _root.myMC.createTextField("tf",0,0,0,800,600);
        _root.myMC.tf.text = "Hello world !";
       init(_root.myMC);
}
    catch (e:Error)
    {trace(e.message);}
    }
"Hello World" does not appear.

In the end I hope to use Sandy with ActionStep to create a business application that combines simple 3D graphics with a forms based application.
I hope to be able to Ant rather that Flashout to develope the system once I get the graphics working reliably.

Anybody gone down that road.

Hi Ron

Well you need to launch the scene you' ve created

World3D.getInstance().render() at the end of the init function.

You project sounds to be really cool ! Do not hesitate to keep us informed

I was too aggressive in removing the comments. I actually have it but it still does not work

function init(stage: MovieClip):Void
{
// screen creation, the object where objects will be displayed.
var ecran:ClipScreen = new ClipScreen(stage, 600, 600, 0xFF0000 );
trace(Flashout.DEBUG+ecran)
// we create our camera
var cam:Camera3D = new Camera3D( 700, ecran);
// we add the camera to the world
World3D.getInstance().addCamera( cam );
// we create the root node.
var bg:Group = new Group();
// and set it as the root node of the world.
World3D.getInstance().setRootGroup( bg );
// and we lauch the scene creation
createScene( bg );
// and now everything is created, we can launch the world rendering.
World3D.getInstance().render();
}

Is there someplace to put a trace to see if the "world" is set up with the box?
Is there someplace to put a trace in the render to see if it is being executed properly?

Your code seems to work. I used it in the Flash 8 IDE, only changing to non class.
What you missed her, is that the camera is in the middle of the cube, at the origin [0, 0, 0].
You have to back up a bit along the negative z axis, like this: ( in the init() method )

CODE

cam.setPosition(0,0,-300);

Thanks.
This line is missing from the first tutorial example and I did not see it get added in the second.
In spite of it being highlighted in colour and clearly explained in the text above the box.

I was trying to get the experience of actually typing the code. I guess that I would have saved a lot of grief by cheating and copying and pasteing (or reading the instructions more carefully).
I guess the only thing more that author could have was to come over and watch me while I typed it.

It did give me a chance to read a lot of the code and practice my debugging skills (need improvement, I guess - next in line for work after my reading abilities).

Learning 3D requires some attention and some time.

You are starting correctly, just keep continue
