Question

每当我尝试绘制一个九点图像和一个舞台时，最后一个被调用的东西被绘制出来。我曾尝试使用正交相机，但没有成功。我尝试过：

batch.setProjectionMatrix(camera.combined);
ninePatch.draw(batch, xPos, yPos, width, height);
stage.act(delta);
stage.draw();

camera = new OrthographicCamera(Gdx.graphics.getWidth(), Gdx.graphics.getHeight());
stage.setCamera(camera)

public class CreateQuiz implements Screen{

    public CreateQuiz(Quiz quiz){
    this.quiz = quiz;
    }

    private Quiz quiz;
    private FallDownPanel fallDownPanel;
    private OrthographicCamera camera;

    @Override
    public void render(float delta) {
    Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT);
    quiz.beginBatch();
    fallDownPanel.render(quiz.getSpriteBatch(), delta);
    quiz.endBatch();
    }

    @Override

    @Override

    Stage stage = new Stage(fallDownPanel.getWidth(), fallDownPanel.getHeight(), false);
    TextFieldStyle style = quiz.getGreenTextFieldStyle();
    style.font.scale(-0.30f);
    TextFieldQuiz test = new TextFieldQuiz("Hej åäö 123 !", style, 0, 2, 400, 16);
    test.setTextFieldListener(new TextFieldListener() {

始终确保您一次只有一个有效Renderer。 Renderer是：

Batch
SpriteBatch
ShapeRenderer
Box2DDebugRenderer如果我没错？
ModelBatch for 3D

我希望我没有忘记一个确保在致电end()新活动之前，始终致电begin() 另请注意，如果您致电Stage，SpriteBatch拥有自己的begin()，并且会为此SpriteBatch调用stage.draw()。因此，请end()之前确保Renderer处于有效stage.draw() 如果您需要ShapeRenderer或任何其他渲染器来绘制Actor（可能导致调试），您必须结束stage s SpriteBatch， draw()方法。确保在方法结束时再次begin() 希望这很清楚。
