Clearing then reloading a new scene

[java3d-interest]

Hi All,

I'm fairly new to Java3D.

I have a maze game which works well so far. I create a universe and add a BranchGroup to it and then fill in the obstacles by reading from a 2D  array.

Now I'd like to be able to load a new level.  How can I clear this scene and allow a new maze to be rendered?

So I create a SimpleUniverse, instantiate a new BranchGroup, and then add a textured floor, sky and then add the obstacles.

It doesn't seem to work just re-instantiating a new BranchGroup again.

I figured it out. You need to detach the branchgroup.

Like this:

        if (sceneBG != null) {
            sceneBG.detach();
        }
        sceneBG = new BranchGroup();
        sceneBG.setCapability(BranchGroup.ALLOW_DETACH);

Switch also helps, if you plan to use same sub-graph later.

Thanks. I didn't know about Switch.
