我正在制作游戏，我正试图在游戏结束时画一个舞台。 当我使用旧版本的Libgdx时，这工作正常。当我更新libGdx版本时，我遇到了以下问题。 我正在为 gameOver 使用相同的背景变量 gamePlayBG ，我将其用于整个游戏并且每次都重置它。目前但舞台不是画画。只有gamePlayBG正在绘制。这是我的代码：
private void gameOver() {
gameOverStage = new Stage();
Gdx.input.setInputProcessor(gameOverStage);
//gameOverStage.setCamera(camera2);
if (isBackgroundMusicPlaying()) {
game.freePlaySound.stop();
}
StretchViewport viewport = new StretchViewport(480, 853);
gameOverStage.setViewport(viewport);
Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
gamePlayBG = new Texture(Gdx.files.internal("data/main_bg.png"));
TextureRegionDrawable gameOverBG = new TextureRegionDrawable();
gameOverBG.setRegion(new TextureRegion(new
Texture(Gdx.files.internal("data/bg_gameover.png"))));
Button mainMenuButton = new Button();
ButtonStyle mainMenuStyle = new ButtonStyle();
mainMenuStyle.up = new TextureRegionDrawable(new TextureRegion(new
Texture(Gdx.files.internal("data/home.png"))));
mainMenuButton.setStyle(mainMenuStyle);
mainMenuButton.addListener(new InputListener() {
public boolean touchDown(InputEvent event, float x, float y, int
pointer, int num) {
if (game.soundBoolean) {
game.objectRemovedSound.play();
}
game.goToMainMenu();
return false;
}
});
TextButton.TextButtonStyle playAgainStyle = new
TextButton.TextButtonStyle();
playAgainStyle.up = new TextureRegionDrawable(new TextureRegion(new
Texture(Gdx.files.internal("data/green.png"))));
playAgainStyle.font = game.scoreFonts;
TextButton playAgainButton = new TextButton("Play Again",
playAgainStyle);
playAgainButton.getLabel().setFontScale(0.70f);
playAgainButton.addListener(new InputListener() {
public boolean touchDown(InputEvent event, float x, float y, int pointer, int num) {
restart();
if (game.soundBoolean) {
game.buttonSound.play();
}
return false;
}
});
Button awardsButton = new Button();
ButtonStyle awardsButtonStyle = new ButtonStyle();
awardsButtonStyle.up = new TextureRegionDrawable(new TextureRegion(new Texture(Gdx.files.internal("data/awards.png"))));
awardsButton.setStyle(awardsButtonStyle);
awardsButton.addListener(new InputListener() {
public boolean touchDown(InputEvent event, float x, float y, int pointer, int num) {
if (game.soundBoolean) {
game.objectRemovedSound.play();
}
/**
* Put navigation to awards screen here.
*/
return false;
}
});
/**
* Time up label settings
*/
LabelStyle timeUpLabelStyle = new LabelStyle();
timeUpLabelStyle.font = game.greenShadowFont;
Label timeUpLabel = new Label("Time up!", timeUpLabelStyle);
timeUpLabel.setFontScale(1.7f);
/**
* Your Score up label settings
*/
LabelStyle yourScoreLabelStyle = new LabelStyle();
yourScoreLabelStyle.font = game.scoreFonts;
Label yourScoreLabel = new Label("YOUR SCORE IS:", yourScoreLabelStyle);
yourScoreLabel.setFontScale(1.0f);
/**
* Setting current score text
*/
LabelStyle currentScoreLabelStyle = new LabelStyle();
currentScoreLabelStyle.font = game.gameTopFonts;
Label currentScoreLabel = new Label("" + score, currentScoreLabelStyle);
currentScoreLabel.setFontScale(1.3f);
/**
* Time up label settings
*/
LabelStyle yourHighScoreLabelStyle = new LabelStyle();
yourHighScoreLabelStyle.font = game.scoreFonts;
Label yourHighScoreLabel = new Label("YOUR HIGH SCORE:", yourHighScoreLabelStyle);
yourHighScoreLabel.setFontScale(0.8f);
/**
* Setting high score text
*/
LabelStyle highScoreLabelStyle = new LabelStyle();
highScoreLabelStyle.font = game.gameTopFonts;
int highScore = game.prefs.getInteger("highScore", score);
Label highScoreLabel = new Label("" + highScore, highScoreLabelStyle);
highScoreLabel.setFontScale(1.1f);
/**
* Creating tables for buttons, background and labels
*/
Table bgTable = new Table();
Table buttonsTable = new Table();
Table timeUpTable = new Table();
Table yourScoreTable = new Table();
Table yourHighScoreTable = new Table();
Table currentScoreTable = new Table();
Table highScoreTable = new Table();
Image gameOverBGImg = new Image(gameOverBG);
bgTable.add(gameOverBGImg);
bgTable.setFillParent(true);
/**
* Adding score labels to table
*/
timeUpTable.add(timeUpLabel);
yourScoreTable.add(yourScoreLabel);
highScoreTable.add(highScoreLabel);
currentScoreTable.add(currentScoreLabel);
yourHighScoreTable.add(yourHighScoreLabel);
/**
* Assigning alignment/positions to buttons
*/
buttonsTable.add(awardsButton).padRight(20);
buttonsTable.add(playAgainButton).padRight(20);
buttonsTable.add(mainMenuButton);
//gameOverStage.addActor(background);
gameOverStage.addActor(bgTable);
gameOverStage.addActor(buttonsTable);
gameOverStage.addActor(currentScoreTable);
gameOverStage.addActor(highScoreTable);
gameOverStage.addActor(yourScoreTable);
gameOverStage.addActor(yourHighScoreTable);
gameOverStage.addActor(timeUpTable);
buttonsTable.setPosition(260, 175);
timeUpTable.setPosition(260, 580);
yourScoreTable.setPosition(260, 480);
currentScoreTable.setPosition(260, 420);
yourHighScoreTable.setPosition(260, 325);
highScoreTable.setPosition(260, 275);
gameOver = true;
if (score >= highScore) {
game.prefs.putInteger("highScore", score);
game.prefs.flush();
}
}
这是我的渲染方法，当时间为零时调用gameOver（）方法：
public void render(float delta) {
// TODO Auto-generated method stub
Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
game.batch.begin();
game.batch.setProjectionMatrix(camera2.combined);
game.batch.draw(gamePlayBG, 0, 0);
if (gameOver != true) {
//Log.d("render------------", "render: "+ delta);
progressBar.draw(game.batch, 1);
progressBar.setPosition(115, 700);
progressBar.setHeight(15);
progressBar.setWidth(270);
camera.update();
game.batch.setProjectionMatrix(camera.combined);
if (lineHud.size > 1) {
for (Sprite sprite : this.lineHud) {
sprite.draw(game.batch);
}
}
for (int i = 0; i < gameObjects.size; i++) {
gameObjects.get(i).draw(game.batch);
}
for (Sprite sprite : this.scoreHud) {
sprite.draw(game.batch);
}
if (stopGameObjects) {
game.batch.setProjectionMatrix(camera2.combined);
levelupButton.draw(game.batch, 1);
/* levelUp.draw(game.batch);
game.levelUpFont.drawMultiLine(game.batch, "LEVEL " + (baseLevel + 1),
(gamePlayBG.getWidth() / 2) - 55,
(gamePlayBG.getHeight() / 2) + 35);
game.levelUpFont.drawMultiLine(game.batch, "KEEP GOING",
(gamePlayBG.getWidth() / 2) - 90,
gamePlayBG.getHeight() / 2);*/
/*game.levelUpFont.drawMultiLine(game.batch,"KEEP GOING",
(gamePlayBG.getWidth() / 2) - 50,
(gamePlayBG.getHeight() / 2) + 50);*/
}
game.tweenManager.update(delta);
game.batch.end();
update(delta);
game.batch.setProjectionMatrix(camera2.combined);
if (gameOver == true) {
this.gameOverStage.act();
this.gameOverStage.draw();
}
}
public void update(float deltaTime) {
if (gameOver == false) {
progressBar.setValue(gameTime);
gameTime -= deltaTime;
}
if (gameTime <= 0) {
if (gameOver == false) {
gameOver();
}
}
}
有什么建议吗？

覆盖resize / Screen的{{1}}方法并更新您的舞台视口。

在你的gameOver方法中，替换
StretchViewport viewport = new StretchViewport(480, 853);
gameOverStage.setViewport(viewport);
与
Viewport viewport = new ExtendViewport(480, 853);
viewport.update(Gdx.graphics.getWidth(), Gdx.graphics.getHeight(), true);
gameOverStage.setViewport(viewport);
