  Missing Behaviours in Xith  (Read 1378 times)

Hardware: parts of a computer that can be kicked


« Posted 2004-05-03 10:44:28 »

Hello,

i start reading all texts and tutorials referring  to Java and 3D.

And because of the simmilarity of Java 3D and Xith i often could use the stuff from Java 3D in my Xith tests.

I also read somthing about behaviours implemented in the Java 3D API.
I think it's a nice way to control the objects and miss it in the Xith API.

Is behaviour going to be implemented?

And somthing else:
In Java 3D it s possible to place a Canvas3D in a JFrame.
Why couldn't I do this in Xith? :-/

Thanks for help

i studied the Xith API and noticed that behavior is implemented.

If i m right, i have to extend my own behavior like KeyBehavior like that

public class KeyBehavior extends Behavior{
      
      private WakeupCriterion criterion;
      
      public void initialize() {
            criterion = new WakeupCriterion() {
                  public boolean hasTriggered() {
                                    return false;
                  }
            };
            wakeupOn(criterion);            
      }

      public void processStimulus(Enumeration arg0) {
      }
      
}


But how can i define the criterion to be triggerd on a KeyEvent from the Canvas3D?

Here i can't fit the things together?
Also, because wakupcriterion is an abstract class.
What should i implement in WakeupCriterion#hasTriggerd()

Are you sure - I didn't think it was yet.  Perhaps I missed the post Smiley

i m sure that the abstract Class Behavior and some subclasses are in the Xith3D packet....

http://xith.org/javadoc/com/xith3d/scenegraph/behavior/Behavior.html

for example  Grin

But what about the wakeupCriterions?
i don't know how to implemement an behaviour without them.

In Java 3D there are many of them like
WakupOnAWTEvent which i need for my Problem.

Can i implement my own WakeupOnAWTEvent by extend WakeupCriterion?
But what should i put in
void hasTriggered()?

I looked at the source code for behavior, and it shows an empty class.   Although the class is there, I don't believe it's implemented yet.

ok, then i have to wait...

but i'm doing fine with an keylitener now...

but i still think that behaviors are the nicer way of controlling objects...
