but when i’ve used jmo model with no skeleton it run normally there aren’t any errors.

the models that i’ve tested are Oto model and Ninja model from http://jmonkeyengine.googlecode.com/svn/trunk/engine/test-data/Models.



Can someone help me please. i’ve to use the models with animation support.

I have same problem when test on Samsung nexus s (android 4.0.4).

Can someone help me please.

Thanks

3

simple put, oto and ninja (especially for animation) weren’t designed for android, use models with less vertices, see if that helps

Thank wezrule for reply.

I’m not a designer, so I’m afraid of blender…

Do you have any model that suitable for android? I’ve only seen oto, ninja and simba on jme svn :frowning:





Thanks & best regards

oto works on android though, I already have him working…it was not with android 4 though.

Are both of your device using android 4?

i’m gonna test it



Once again that might be a Dalvik gift… -_-

It’s fixed in last SVN.

There was an issues with ByteBuffers that are apparently not handled the same way on android 4.0 than with prior versions.

I tested the fix on desktop (win 7 64), android 2.3.6 and android 4.03 and it works fine.

Thank nehon.



I’ve fixed it by load mesh.xml instead of j3o.



But now I stuck in another problems:

  • on my pc, I work fine.
  • on android fone (samsung nexus s run 4.0.4) I can’t init HeightMap from Img : the following line return null.

    heightmap = new ImageBasedHeightMap(heightMapImage.getImage(), 0.25f);

    so when I put this line into try catch, the log cat show :

    http://i527.photobucket.com/albums/cc358/chg76113/121.png

    and the result is the terrain is flat

There has not been a lot of testings with terrain on android

We’ll have to look into this, but the android todo list is already kinda crowded.





DDS files are not supported on android, you have to load 6 different images for skybox (SkyBoxFactory has a method for this)
