在libgdx中切换到游戏结束屏幕

Question

当我的游戏结束时，我试图改变屏幕到游戏结束屏幕，但它没有这样做，只是闪烁当前的游戏屏幕。

   @Override
public void render(float v) {
    Gdx.gl.glClearColor(0, 0, 0, 1);
    Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT);
    if (state == gamestate.PAUSED) {
        // draw pause screen
    }
    else if (state == gamestate.GAMEOVER || score <= 0) {
        game.setScreen(new endGameScreen(game, score));
        stage.clear();
        return;
    }
    else {
        player.update();

        stage.draw();
        batch.begin();
        mBtn.setPosition((cam.position.x - (Gdx.graphics.getWidth() / 2)) + 10, (cam.position.y - (Gdx.graphics.getHeight() / 2)) + 10);
        pBtn.setPosition((cam.position.x + (Gdx.graphics.getWidth() / 2)) - pauseWidth, (cam.position.y - (Gdx.graphics.getHeight() / 2)) + 10);

        batch.draw(player.getCurrentFrame(), player.getPosition().x, player.getPosition().y);

        cam.position.set(player.getPosition().x, Gdx.graphics.getHeight() / 2, 0);
        batch.setProjectionMatrix(cam.combined);
        cam.update();

        batch.end();

        if(player.getPosition().x >= finishLine.getX()) {
            System.out.println("End Game!!!");
            endGame();
        }
    }
}

游戏结束画面

public class endGameScreen implements Screen {

int score = 0;
String scoreTxt = "";
Stage stage;
SpriteBatch batch;
BitmapFont font;
Game game;

public endGameScreen(Game game, int score){
    this.score = score;
    this.game = game;
}

@Override
public void render(float v) {
    batch.begin();
    font.setColor(1.0f, 1.0f, 1.0f, 1.0f);
    font.draw(batch, scoreTxt, 25, 100);
    batch.end();
}

@Override
public void show() {
    batch = new SpriteBatch();
    font = new BitmapFont(Gdx.files.internal("font.fnt"));
    stage = new Stage(Gdx.graphics.getWidth(),Gdx.graphics.getHeight(),true);
}

很有可能是游戏结束画面中缺少清屏造成的。从我的经验来看，这导致了不确定的行为，在桌面和一些手机上工作正常，而在其他手机上却变得疯狂的黄白色浮华。您仍然可以看到上一个屏幕，因为您没有通过清除将其从设备的硬件屏幕中删除。

所以只需添加glClear行，就像在其他类中一样。
