Callback in Babylon.SceneLoader.ImportMesh

[BSS]

Hi guys,

I have  problem with babylon.sceneloader.importmesh. I tried importing mesh from .babylon file. Its importing correctly. but  the problem is the callback in importmesh function is called twice.because of this i got meshes. I need to call the callback only once. 

Help me out,

 

Note:

This is happening only in windows store app. Not in any other application.

Hi, 

 

The callback should be called only once. Can you share your code please ?

Me too have the same issue, Anybody has any solution ?

Code :  

BABYLON.SceneLoader.ImportMesh("", "scene/", "link1.babylon", scene, function (newMeshes){// , particleSystems, skeletons) {

                       link1 = newMeshes[0];

                        link1.position = new BABYLON.Vector3(0, -2, 0);

                        link1.scaling = new BABYLON.Vector3(1.5, 1.5, 1.5);

                    });

Can you confirm that ImportMesh is called just once?? (by adding an alert for instance)

[San]

Ya dude, I tried adding console.log before and inside the import mesh.

Before Import mesh its calling once but inside (callback) it is calling twice. This issue is coming only in windows store app but the same is working fine in browser.

Please help me.

Finally did a bad fix 

This issue is coming because of the following method calling twice "importMeshFromData(data)" in bababylon.js. Don't know whats happening before this call. The fix here is as follows in babylon.2.1.debug.js

 

Before:

BABYLON.Tools.LoadFile(rootUrl + sceneFilename, function (data) {     

                        importMeshFromData(data);

                    }                        

                }, progressCallBack, database);

------------------------------------------------------------------------------------------------

After : Added a new variable "scene_Filename"

BABYLON.Tools.LoadFile(rootUrl + sceneFilename, function (data) {                    

                    if (scene_Filename == "") {

                        scene_Filename = rootUrl + sceneFilename;

                        importMeshFromData(data);

                    }

                        

                }, progressCallBack, database);

 

I know its a bad fix, can anybody help me in finding the root course ?

*remember its happening only in windows store app

You should create a very simple windows store app that only demonstrates the issue and then post the project files for that here.

Guys,

 

Attaching the sample project.

I have added a console.log inside import mesh in default.js. The below code is running twice and adding two meshes instead of one.

Please find the default.js inside "JSUniversalAPP.shared"

 

 BABYLON.SceneLoader.ImportMesh("", "scene/", "base.babylon", scene, function (newMeshes, particleSystems, skeletons) {

            console.log("----------- base mesh loaded -------------");

 });

The problem is in method Database.prototype.checkManifestFile.

I run the demo app in debug, and here it what is done:

-checkManifestFile

   - creating xhr request : https://github.com/BabylonJS/Babylon.js/blob/master/src/Tools/babylon.database.ts#L64

   - try {xhr.send()} : https://github.com/BabylonJS/Babylon.js/blob/master/src/Tools/babylon.database.ts#L96

   - Entering in the catch block : https://github.com/BabylonJS/Babylon.js/blob/master/src/Tools/babylon.database.ts#L99

   - Later, entering in the 'load' event : https://github.com/BabylonJS/Babylon.js/blob/master/src/Tools/babylon.database.ts#L70

 

The last step should not happen. Maybe a bug only on Windows apps ?

[San]

Ya, its a bug only in Windows app. Somebody who knows the babylon better, please take an initiative and fix this bug

if this is a bug in windows app then the bug has to be fixed in windows
