Can't deserialize object

[JKumar]

Hi,

        I am having a md2 file with 1.67MB and after serializing, it comes to be 9.78 MB.


It gets serialized with some error at the last  and when i am trying to deserialize in jPCT-AE it says

"Can't deserialize object"

see the log

Is there issue with md2 file as its running fine in  "md2Viewer 1.4".

Any guess

[EgonOlsen]

Well, then just do what the error message tells: "Too many sub-sequences defined. Modify configuration to allow a higher number". There's a setting in Config: http://www.jpct.net/doc/com/threed/jpct/Config.html#maxAnimationSubSequences. The default is 20 which is fine for all md2s that i've ever seen...but obviously not for yours...

[EgonOlsen]

BTW: 10mb is pretty huge...have you serialized it with reduced set to true? You can greatly reduce disc/card usage by zipping it and load the zipped version instead but it'll still consume a lot of memory. Are you sure that you need all the sub-animations?

Hi,

        My Code is running fine in 2.1 but when i am using it in device with 2.2. Its not able to Deserialize my model.

     Everything running fine in 2.1.

Any issue with jPCT and SDK 2.2 ?

[EgonOlsen]

No, no issues. And the log that you've posted simply indicates a configuration mistake on your side (as mentioned above) that has nothing to do with the underlying platform. Maybe you are getting some different problem on 2.2, but then that's not a part of your posted log!?

When i run this in 2.1, it runs fine but when i use the same file 2.2 it gives error "Can't Deserialize" (see attached log file...use wordpad for the clear view).

I don't know y its happening with the same code for different Android SDK

There you have your problem:

Code Select Expand


10-20 10:46:56.469: DEBUG/asset(3702): Data exceeds UNCOMPRESS_DATA_MAX (6400588 vs 4194304)


Android limits the file size and these limits vary from version to version. Either zip the file and load it via a zipped inputstream instead or rename it to .mp3. That makes Android think that it's already compressed and the error should go away.

Hi,

      Though i tried with zip but no success. But my requirement got changed and the model is reduce from 19 animations to 12 animations which helped the code to run smoothly in both 2.1 and 2.2.

I thank you for jPCT which running as the base of my project.

I have another query regarding multi-touch.As my target device is 2.2 and above so i have multi-touch support.

My requirement is to use touch button combination on the screen and that can only be acheived using multitouch.

And my question is- Is there any help from jPCT for multi-touch? What is the user of Overlay class in the jPCT?  Any link between multi-touch and overlay?

[EgonOlsen]

No, there's no binding from jPCT to any gui or input components. If you want to show controls for multi-touch input components, just blit them to the screen or write your own, simple gui component system that does this for you.
I don't recommend to use Overlay, if you can get away with blitting, because it's more expensive...and on Android, that actually counts.

Hi, I have change file to mp3. It don't success
So I load it via zip input stream. But it also don't success.
Please help me.

This is the deserialize code I have write

    Config.maxAnimationSubSequences=100;

        Texture grass2 = new Texture(textureString);

        Object3D grass = Loader.loadMD2(obj3dString, 5);

Get a newer version of desktop jPCT. You serialized file format is too old. It doesn't contain the version info that i've added some time ago.
