libgdx and android application. Image as background

问题

I am new and I just start my journey with libgdx. I would like to know how I can do image.png in resolution 960x640 as background in my game? This is possible? Thx for advices and forbearance. Maybe you hava a simply tutorial? This is my render class:

public void render() {

     texture = new Texture(Gdx.files.internal("E:/background.png"));

     Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT); 
     batch.begin();
     batch.draw(texture, 0, 0);
     batch.end();
}

Second question. I need to insert two active images, active means when I click on that image, the next image show me on the screen. I want to implement action when I click on that picture.

In your create() method, create a new Texture referencing your image.png, and then use your existing SpriteBatch to render it in the render() loop. Immediately after your GL.clear() call, go your batch.draw(backgroundTexture, 0. 0) and make sure you're in OrthographicProjection mode for your camera.

回答2:

first you have to set the view port do this in your create method

`float scrw = 960; float scrh = 640;

    camera = new OrthographicCamera();
    camera.viewportHeight = scrh;
    camera.viewportWidth = scrw;

    camera.position.set(camera.viewportWidth * .5f,
            camera.viewportHeight * .5f, 0f);
    camera.update();`

create a texture

texture = new Texture("data/background.png");

put this texture in a sprite like this

sprite=new sprite(texture);

and then set the size like this

sprite.setsize(960,640);

and draw it in your render methods between batch.begin and batch.end

sprite.draw(batch);
