Background transparent in insidelayout example about min3d HOT 8 CLOSED

Look at how Scene.java works. Min3D uses some coding conventions that are not 
as you learned it in your SCJP-classes ;) It's more related to action script 
where there are explicit getters and setters available.

scene.backgroundTransparent(true); Should do the trick.

(I would vote to change Min3D to use getBackgroundTransparent() and 
setBackgroundTransparent(boolean b) btw.)

I'm also trying to get background transparency to no avail.
Changing the ExampleInsideLayout initScene() to:
        scene.lights().add(new Light());

        scene.backgroundColor().setAll(0xff444444);
        scene.backgroundTransparent(true);
        _cube = new Box(1,1,1);

should surely have made it transparent, but instead it just renders on a black 
background instead of the background colour. To test this I added backgrounds 
to R.drawable.listActivity (the root) and to the LinearLayout across the middle 
of the layout.

Is there a way to let the backdrop texture show through? It's what we need in 
my game.

Thanks for any help!

Hi, I've added a 'recipe' demonstrating transparency in 
min3dSampleProject1/ExampleTransparentGlSurface.java.

For device compatibility reasons, I'm reluctant to create the functionality for 
transparency thru a single simple method call, but hopefully this will suffice.

BTW, the Scene.backgroundTransparent() getter and setter got removed, since its 
name was a little misleading and it didn't add any useful functionality on its 
own.

Greetings, I have been attempting to implement a translucent glsurfaceview over 
an image background for a while now without success.  I'd also like a few 
widgets (buttons, textviews, etc) on top of the glsurfaceview.

In ExampleTransparentGlSurface.java the comment says its possible, how is this 
accomplished?  Would you give an example?

I've attempted several variations of the following:

# ExampleTransparentGlSurface.java
protected void onCreateSetContentView()
{
    setContentView(R.layout.transparent_layout);
    ((LinearLayout)findViewById(R.id.surface_holder)).addView(_glSurfaceView);
}

protected void glSurfaceViewConfig()
{
    _glSurfaceView.setEGLConfigChooser(8,8,8,8, 16, 0);
    _glSurfaceView.getHolder().setFormat(PixelFormat.TRANSLUCENT);
}

public void initScene() 
{
    scene.backgroundColor().setAll(0x00000000);
}

# transparent_layout.xml
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent" android:layout_height="fill_parent">

    <!-- Background Image -->
    <ImageView android:layout_width="fill_parent"
        android:layout_height="fill_parent" android:src="@drawable/earth" />

    <!-- Holds Gl Surface View -->
    <LinearLayout android:layout_height="fill_parent"
        android:layout_width="fill_parent" android:id="@+id/surface_holder" />

    <!-- Widgets, etc. should be on top of 3d environment -->
    <Button android:layout_width="fill_parent"
        android:layout_height="wrap_content" android:text="This is a big button" />

</FrameLayout>

Hi, i have the same issue with Background transparency; does anyone found a 
solution to fix this? , 
It worked for me when i used a SurfaceView in background but not over an image 
background, my code is almost the same as "[email protected]"

it worked for me that way:
@Override 
    protected void glSurfaceViewConfig()
    {
        _glSurfaceView.setEGLConfigChooser(8,8,8,8, 16, 0);
        _glSurfaceView.getHolder().setFormat(PixelFormat.TRANSLUCENT);
        _glSurfaceView.setZOrderOnTop(true);
    }

public void initScene()
    {

        scene.backgroundColor().setAll(0, 0, 0, 0);
//rest of your code
}

it worked for me that way:
@Override 
    protected void glSurfaceViewConfig()
    {
        _glSurfaceView.setEGLConfigChooser(8,8,8,8, 16, 0);
        _glSurfaceView.getHolder().setFormat(PixelFormat.TRANSLUCENT);
        _glSurfaceView.setZOrderOnTop(true);
    }

public void initScene()
    {

        scene.backgroundColor().setAll(0, 0, 0, 0);
//rest of your code
}

hey explain to me how to do exactly? I've never used <! - Holds Gl Surface View 
-> 
<LinearLayout android: layout_height = "fill_parent" 
android: layout_width = "fill_parent" android: id = "@ + id / surface_holder" 
/> 

I just object and I want to put a button ...
