我在eclipse中安装了Gradle并想要导入一个libgdx Gradle项目.但是当我点击"Build Model"按钮时,我在加载条的50%左右出现错误.这是问题所在:

我的游戏中有大量的2D图像,有多层.我用spritebatch()和orthographicCamera().我有一些关于表演的基本问题:

1. 使用Atlas是加载图像的更快方法吗？
2. 什么是更快的工作,Pixmap(并在绘制之前转换为纹理)或纹理？
3. 当我制作多层图像时,我应该使用Texture.draw(或Pixmap.draw用于Pixmap),制作最终图像然后渲染它吗？或者我应该在spritebatch.begin()和spritebatch.end()？
4. 有没有办法跟踪"脏精灵"(屏幕中两帧之间发生变化的部分)并仅渲染此区域以提高性能？
5. 另外,如何查看程序资源占用的内存量,以及如何管理它？(也许这个问题有点困难)

感谢您的帮助(欢迎任何其他一般建议)
