Question

您好我是LibGDX的初学者。我有一个移动的相机，我想在相机移动时显示得分。我已经完成了这个，但是当相机移动时，文字（分数）会震动。我不知道如何解决这个问题。这是我的代码。

它震动的原因是默认情况下文本位置四舍五入为整数位置。您可以在每个文本对象上设置font.setUseIntegerPositions(false)以避免这种情况。

但是，尝试使用游戏世界的相机移动GUI是不切实际的。为您的GUI创建一个单独的相机。

public void render(SpriteBatch sb) {
    sb.setProjectionMatrix(gameCam.combined);
    sb.begin();

    sb.draw(bg,gameCam.position.x - (gameCam.viewportWidth /2),0);

    sb.draw(groud,groundpos1.x,groundpos1.y);
    sb.draw(groud,groundpos2.x,groundpos2.y);


    sb.setProjectionMatrix(guiCam.combined);
    String s = Integer.toString(SCORE);
    String h = Integer.toString(highscore);
    font.draw(sb, s, font.getSpaceWidth(), guiCam.viewportHeight / 2 - 39);
    high.draw(sb, h, guiCam.viewportWidth /2, guiCam.viewportHeight / 2 - 39);
    sb.end();
}
