我希望你能帮我找到错误。干杯,Joshflux

编辑：我很确定，它必须做一些事情与窗口的大小。如果我将窗口的高度从800调整为200，那么左角的人看起来是一样的，但是中间的人要小得多。但还是不知道怎么解决...

问题是您的levelStage使用了不同的相机。

new Stage();

创建一个具有自己的摄像机和缩放视区的舞台。在这里创建另一个相机：

camera = new OrthographicCamera();
camera.setToOrtho(false, 800, 480);

注意，这并不设置窗口大小！

batch.setProjectionMatrix(levelStage.getCamera().combined);
