今天优化了下昨天的代码，并且添加了树木和其他资源的生成。还修复了接近石头后，挖掘图标不出现的bug。目前可以在unity中稳定60-70fps。

更新后的代码：（还是比较乱 没整理也没写注释，最后一块说明）

其中在selectedobjet创建之后，用createothers函数判断当前的cube类型，在相应的位置上生成相应的资源，比如石头，草，树木。其中资源的类型和旋转再用随机数进行随机产生。
另外，优化方面，在建立世界后删除这个脚本，并且删除前，把缓存预先生成的物体destroy掉。
至于ui挖掘图片的显示，是因为之前把canvas给误删了，再加上之后，把摄像头选为world space就能正常显示了。
目前的效果：
目前大概就这样。优化方面体会很多，首先是代码逻辑要简化，还要注意update中，尽量不要设计太复杂的算法。能预先载入的，能异步执行的尽量做，节省cpu和gpu。
至于渲染方面，shader编程还没涉及到，很深的学问。。。
随即世界的生成完成了大概20%预期，接下来要做更复杂的。今天就这样。
