无法同时绘制图块和阶段的图像 [英] Can't draw a ninepatch image and stage at the same time
问题描述
每当我尝试绘制一个9补丁图像和一个舞台时，最后一个被称为绘制的东西就会被绘制.我尝试使用正交摄影机，但未成功.我尝试过的:
Whenever I try to draw a ninepatch image and a stage the last thing that's called is being drawn. I have tried to use a orthographic camera but didn't succeed. What I have tried:
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)
代码
CreateQuiz类
The CreateQuiz class
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
public void resize(int width, int height) {
}
@Override
public void show() {
fallDownPanel = new FallDownPanel(FallDownPanel.START_LOWER_SIDE, 200, quiz.getTextureAtlas().createPatch("fallDownWindow"));
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() {
@Override
public void keyTyped (TextField textField, char key) {
if (key == '\n') {
textField.getOnscreenKeyboard().show(false);
}
}
});
stage.addActor(test);
Gdx.input.setInputProcessor(stage);

推荐答案
始终确保一次只有一个活动的Renderer. Renderer是:
Always make sure you have only one active Renderer at a time. The Renderers are:
-
Batch -
SpriteBatch -
ShapeRenderer -
Box2DDebugRenderer如果我没记错的话 -
ModelBatch用于3D
BatchSpriteBatchShapeRendererBox2DDebugRendererif i am not wrongModelBatchfor 3D
我希望我不会忘记一个.
确保始终调用end()作为活动对象，然后再调用begin()作为新对象.
还请记住，Stage有其自己的SpriteBatch，并且如果您调用stage.draw()，它会为此SpriteBatch调用begin().因此，请确保在stage.draw()之前先end()活动的Renderer.
如果需要ShapeRenderer或任何其他渲染器来绘制Actor(可能是调试原因)，则必须结束stage s SpriteBatch，这是通过draw()方法获得的.确保在方法末尾再次begin().
希望这足够清楚.
I hope i did not forget one.
Make sure you always call end() for the active one, before calling begin() for a new one.
Also remember, that a Stage has its own SpriteBatch and it calls begin() for this SpriteBatch, if you call stage.draw(). So make sure you end() the active Renderer, before stage.draw().
If you need a ShapeRenderer or any other renderer to draw an Actor (maybe cause of debuging), you have to end the stages SpriteBatch, which you get with the draw() method. Make sure you begin() it again at the end of the method.
Hope this is clear enough.
