Title: serialization for Object3D
Post by: haijin on May 31, 2011, 10:13:12 pm

I seem to have a problem serializing Object3D... I am using a workaround which is not that nice (re-instancing with relevant data instead of serializing). I wonder why is that happening: trying to serialize generates errors because it can't serialize (unrelated) stuff like GLThread or other threads. In this trace, ThrowableObject3D line 32 is for writeObject(object3D):

There's a cache for matrices that uses the thread as key. It wasn't transient...i've changed this and uploaded a new alpha version. Please give it a try: http://www.jpct.net/jpct-ae/download/alpha/jpct_ae.jar (http://www.jpct.net/jpct-ae/download/alpha/jpct_ae.jar)

I replaced the library but I'm getting an error with MemoryHelper:

UNEXPECTED TOP-LEVEL EXCEPTION:
java.lang.IllegalArgumentException: already added: Lcom/threed/jpct/util/MemoryHelper;

... even after restarting the IDE
