屏幕截图

游戏中可使用如下代码进行截屏

byte[] pixels = ScreenUtils.getFrameBufferPixels(0, 0, Gdx.graphics.getWidth(), Gdx.graphics.getHeight(), true);

Pixmap pixmap = new Pixmap(Gdx.graphics.getWidth(), Gdx.graphics.getHeight(), Pixmap.Format.RGBA8888);
BufferUtils.copy(pixels, 0, pixmap.getPixels(), pixels.length);
PixmapIO.writePNG(Gdx.files.external("mypixmap.png"), pixmap);
        pixmap.dispose();
