[SOLVED] Cant loadModel with static rigidbody

Amedeo_Braggio · December 31, 2022, 2:34pm

If i do:

 Node rootNode = (Node) assetManager.loadModel(mapToload);

where mapToLoad = a string with path of j3o.

and in this j3o i have a spatial with static RigidBody added from SceneComposer, i get a error:

Which version of Minie is included in your application?

Amedeo_Braggio · January 1, 2023, 6:42pm

by gradle:

implementation "com.github.stephengold:Minie:5.0.0"

sgold · January 2, 2023, 12:58am

That’s caused by a bug in Minie. I’ll get to work fixing it!

sgold · January 2, 2023, 3:40am

Try:

implementation 'com.github.stephengold:Minie:7.0.1'

Amedeo_Braggio · January 2, 2023, 12:00pm

no, same error…

sgold · January 2, 2023, 5:53pm

Please post the new stack trace.

A bug, obviously, but a different one. I am working on a fix.

Please try:

Amedeo_Braggio · January 3, 2023, 6:08pm

now works fine! load the model (no error) and with addAll add the RidigidBody!!
