Java games rock!


« Posted 2005-05-16 13:27:41 »

I'm trying to set a transformgroup's transform3D object to the initial rotation of 0..

I used the transform3D.setIdentity() method but it keeps throwing a null pointer expection at me?

Any idea why this is doing this?

Please help!!

um yes.  if  "mytransform. setIdentity()" throws a null poinerte xception then by definition mytransform == null.

As to WHY it equals null, id have to see your code but i gaurantee its wrong.  the most likely thing is that the variable is never beign set to reference an actual object.

Got a question about Java and game programming?  Just new to the Java Game Development Community?  Try my FAQ.  Its likely you'll learn something!
