Hi again..

i need fadeable widges for my HUD (I want to fadeout a widget when a mouseover occures). Is there any way to change the apperance of a widged or do you know any other way to achieve that?

Snipped

Code:

Texture tex = TextureLoader.getInstance().getTexture( "test.jpg" );
Widget test = new Image( 40f, 40f, 1, tex );
this.addWidget( test, 10, 10 );

Well, you could do that by directly manipulating the SceneGraph. But it is not a good idea. It should be done through SceneGraph abstraction. So it needs special support in the HUD. But it is not too difficult. I will do that after some other tasks to do. Is it ok, if I do it within the next two weeks? I guess, it is a nice-to-have rather than a must?

Sure. That would be great. Thx

Yes its just a additional feature. Im still working on shadowcasting. I hope ill finish everything on-time.

I have added this feature now. You can simply use the setTransparency() method on each Widget. WidgetContainers also have an additional boolean parameter for the children.

Works fine for panels but transparency is not working with buttons.
I get a nullpointer exception for:

"private NinePanelsRect image;"
org.xith3d.ui.hud.widgets/Button.java - line 268

Code:

   @Override
    public void setTransparency(float transparency)
    {
      super.setTransparency( transparency );
   
        ShapeUtils.setShapesTransparency( image, transparency, true ); // <- Exception
    }

I tried to do a manual init(); but it had no effect. I'll keep looking for a workaround.

Solved..
init() is started after adding the Widget to HUD therefor image is null. Just place the setTransparency method after the addWidget and everything works fine.

Code:

base.addWidget( sphereButton, 825f, 180f );
sphereButton.setTransparency(0.5f);

Thanks for the hint. I will modify the Button class to handle this internally.
