  <p>This is my code for drawing</p>
  
  <pre><code>@Override
  public void create () {
  
      mWidth = Gdx.graphics.getWidth();
      mHeight = Gdx.graphics.getHeight();
      mScale = Math.max(mWidth, mHeight) / 20f;
  
      backgroundTexture = new Texture(Gdx.files.internal("backBlue.png"));
  
      ShaderProgram.pedantic = false;
  
      backgroundShader = new ShaderProgram(VERT, FRAG);
      if (!backgroundShader.isCompiled()) {
          System.err.println(backgroundShader.getLog());
          System.exit(0);
      }
      if (backgroundShader.getLog().length()!=0)
          System.out.println(backgroundShader.getLog());
  
      backgroundBatch = new SpriteBatch(5, backgroundShader);
  }
  
  
  @Override
  public void render () {
      Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
  
      backgroundBatch.begin();
      backgroundBatch.draw(backgroundTexture, 0, 0, mWidth, mHeight);
      backgroundBatch.end();
      ...
  }
  
  @Override
  public void resize (int width, int height) {
      mWidth = width;
      mHeight = height;
      mScale = Math.max(width, height) / 20f;
  
      backgroundShader.begin();
      backgroundShader.setUniformf("resolution", width, height);
      backgroundShader.end();
  }
  </code></pre>
