Space Shoot教程学习笔记

Space Shoot教程学习笔记

环境：Unity3D 5.0.1f1

注意事项
[1]完成Space Shoot教程所需要的Assets在官网很难download，我们只能在其它地点下到这个资源，然后导入。
这里假设，我已经下载到了”Unity Projects Space Shooter.unitypackage”文件，
新建Unity3D工程后，进入主菜单->[Assets]->[Import Package]->[All]->[Custom Package…]->[Importing package]
->[I Make a Backup, Go Ahead!]进行导入。

[2]主菜单[Edit]->[Render Settings]被移到了[Window]->[Lighting]下面

[3]
使用“rigidbody.velocity = movement”会出错，得用下面的代码替换。
GetComponent().velocity = movement;

[4]Documentation ,[Ctrl]+[‘]

[5]关于”yield”方法。
[5-1]首先是所有update方法先都运行完才运行yield后面的内容，
就像有个update总管把所有的这一帧的update方法集合起来先搞定这一帧所有update方法，
然后把所有的欠下的yield后面的内容执行掉，就接着运行下一帧。
[5-2]只能在协同程序里面使用。例如你不能在Update和FixedUpdate中调用“yield”方法。
[5-3]你可以在Start方法中启动“协同程序”.
void Start ()
{
StartCoroutine (你的方法名());
}
[5-4]如何使用”yield”方法的例子

[6]使用Debug.Log可以在程序运行的时候，打印出调试信息。

[7]
audio.Play()改为下面这条代码
GetComponent().Play ();
