[solved] Unknow Format loading in a TcastleScene

3D

Hello, I trying to load a glf file using code, But I got following code:

procedure TmainForm.Button1Click(Sender: TObject);
var
Robot: TCastleScene;
s, path: string;
begin
Robot := TCastleScene.Create(Self);
s := GetCurrentDir;
s := s + PathDelim + ‘data’ + PathDelim + ‘IRB6700_300_270__04.glf’;
path := FilenameToUriSafe(s);
World.Add(Robot);
Robot.Url := path;
end;

And I got the following error:

If I load the same file in castle game viewer I don’t have any problem.

My program, is lcl application. I use a TCastleControl in a form.
World is a castle transform ( TCastleTransform)

On create, I wrote:

View := TCastleView.Create(Self);
View.DesignUrl := ‘castle-data:/gameviewmain.castle-user-interface’;
CastleControl1.Container.View := View;
ViewPort := View.DesignedComponent(‘ViewPort1’) as TCastleViewport;
World := View.DesignedComponent(‘world’) as TCastleTransform;

All code can be found here:

You have a simple typo in code :slight_smile: .glf instead of .gltf – you missed t at https://github.com/Blueicaro/worldzonesviewer/blob/ef97a85bd7ddcbcee34808a2e3d269321b9dd2f8/main.pas#L208 . So it’s unrecognized extension for CGE.

To avoid such mistakes, you can instead right-click on the model in CGE editor, and use “Copy URL”:

You do not need to do such conversion filenames<->URLs in this case :slight_smile: Just write

Robot := TCastleScene.Create(Self);
Robot.Url := 'castle-data:/IRB6700_300_270__04.glf';
World.Add(Robot);

… and it will work on all platforms (even ones without a regular) filesystem and is simple :slight_smile: That’s exactly why we invented castle-data:/ protocol, see Data directory and castle-data:/ URL protocol | Manual | Castle Game Engine .

Hello, thanks for the answer. But there is one thing that I don’t understand.
I downloaded the model from here:

All files have the extension .GLB. I open in Castle Game Editor without change any thing

But, Why Have to change the file extension to load in my code?

P.D. I changed the extension as you said, and now it’s works

  • .glb is valid file extension and .gltf is valid file extension (they are variants of the glTF model format ).

  • You needed to change it, as you wrote in code (I guess it was just a typo) .glf. And this is neither .glb nor .gltf :), and is just unrecognized extension for CGE (and other software).
