Export/Import Babylon file

[Nastro]

Hi !

I tried to import a babylon file in the Babylon JS SandBox but when i try he tell me "Uncaught SyntaxError: Unexpected token ."

I crete the file with this code :

    serializedMesh = BABYLON.SceneSerializer.Serialize(scene);
    strMesh = JSON.stringify(serializedMesh);

Unfortunatly i can't join you my file but if i generate it with your Serialize method i can't have problems ?

I can visualise my scene in my project but no in Sandbox ...

Any ideas ?

I work on 2.4 release.

Hi @Nastro.  Can you check the file with a JSON validator, please?  Tell us what the validator reports.  Thanks!

Serialize SHOULD work

 

What error do you get in the Sandbox console?

Hi,

encodeURIComponent() rule some problem sometimes.

var serializedMesh = BABYLON.SceneSerializer.Serialize(scene); 
var str_Mesh = JSON.stringify(serializedMesh);
var strMesh = encodeURIComponent(str_Mesh);

@Wingnut : With the JSON validator i have this error :

I have an error on a point but i don't know why :/

@Deltakosh The error message on Sandbox is :  Uncaught SyntaxError: Unexpected token

 

[Nastro]

@Dad72 i will try your idea but with this error i think is an other thing :/

[Nastro]

@Dad72 no working when i used  encodeURIComponent()

[Dad72]

In your error it looks like something is missing here (in red (')):

Expecting 'EOF', '}', ',', ' ']', got 'undefined'

[Nastro]

I don't think.

If you see the vertexData i have on point like this " 61...32564 " and i don't know why. Maybe the number is very long and he cut it ? 

[Wingnut]

  Those 3 periods...

4 hours ago, Nastro said:

Error: Parse error on line 581: ...4.87901823733, 3, 61...32564, 32566,

...look really unhealthy.  I cannot think of a reason why BABYLON.SceneSerializer would cause those.  @Dad72... do you think var strMesh = encodeURIComponent(str_Mesh); line... could cause those 3 dots?

@Nastro and I think about the same thing at the same time. 

[Nastro]

I tried to use the method encodeURIComponent() but no work for this error...

[Dad72]

no Wingnut, encodeURIComponent(str_Mesh); do not could cause this probleme.

And without encodeURIComponent(), the error is the same?

 

[Nastro]

This error appear without "encodeURIComponent()".

With encode i have looks like : (code is not complete)

[Wingnut]

hmm.  Let's look at the sequence.

619768.9228536393, 77714.87872559811, 3, 619768.9228536393, 77789.08973176266, 3, 619768.9771462772, 77789.09002440188, 3, 619768.5771463606, 77714.87901823733, 3, 61...32564, 32566, 32567, 32568, 32569, 32570, 32568, 32570, 32571, 32572, 32573, 32574, 32572, etc

We see repeated 619768 values... following a pattern... and then... in the middle of the (possibly final...) 619768... it goes to hell... after the '61'.

And... the pattern/values do a DRASTIC change.

See it?  Sure ya do.  We all do.  What the heck happened there?  And what are those 3256X numbers?  They don't look much like vec3 values.  They look... like indices.  Why would indices be put in the same array ... as positions data?  (in the .babylon file).

Something went ka-boom, @ triple period.  A fuse popped right there, or something.   hmm.

[Nastro]

Yeah i see... The number who explode is the last before "indices" number... something wrong but ??

[reddozen]

maybe an overflow?

[JCPalmer]

I would recommend only using 4 decimals for geometry using toFixed(4).  Blender & 3dsMax both do.  Blender further eliminates trailing zeros & removes unnecessary dots.  This reduces things massively.
