LZ-Says：不畏艰难，一起干！！！

前言

对于任何一门新接触的语言，我们总会因为不熟悉从而导致犯一些基本的低级错误，对于错误，我们要秉承拥抱的态度，遇到的越多，也意味着我们每天在前行，错误，不过尔尔~

异常收集汇总

Step 1：MissingComponentException: There is no ‘Rigidbody’ attached to the “Player” game object, but a script is trying to access it.

错误日志：

MissingComponentException: There is no 'Rigidbody' attached to the "Player" game object, but a script is trying to access it.
You probably need to add a Rigidbody to the game object "Player". Or your script needs to check if the component is attached before using it.
UnityEngine.Rigidbody.AddForce (Vector3 force) (at C:/buildslave/unity/build/artifacts/generated/common/modules/Physics/DynamicsBindings.gen.cs:1426)
Player.Update () (at Assets/Script/Player.cs:23)

问题解决：

为你的游戏组件添加刚体即可。

Step 2：The referenced script on this Behaviour (Game Object ‘Player’) is missing!

错误日志：

The referenced script on this Behaviour (Game Object 'Player') is missing!

错误解决：

例如，有的预制件的组件中包含了脚本，但是这个脚本已经删除了，那么在脚本组件的位置将显示一个丢失的信息。你需要移除这个组件，或者替换上更新后的脚本。其它的情况大体如此。细心检查，将丢失的资源补上或者移除即可。还要一种是这个预制件本来分配了一个layer或者tag，但是后来这个layer或tag被删除了，那么这里的layer或tag将显示none，你需要给它分配一个新的layer或tag。

Step 3：Because you are not a member of this project this build will not access Unity services.

问题提示：

问题解决：

一般由于Unity连接不上服务导致。

Step 4：Exception: JNI: Init’d AndroidJavaClass with null ptr!

问题日志：

Exception: JNI: Init'd AndroidJavaClass with null ptr!
UnityEngine.AndroidJavaClass..ctor (IntPtr jclass) (at C:/buildslave/unity/build/Runtime/Export/AndroidJavaImpl.cs:622)
UnityEngine.AndroidJavaObject.get_JavaLangClass () (at C:/buildslave/unity/build/Runtime/Export/AndroidJavaImpl.cs:600)

UnityEngine.AndroidJavaClass..ctor (System.String className) (at C:/buildslave/unity/build/artifacts/generated/common/runtime/AndroidJavaBindings.gen.cs:92)
Test.OnGUI () (at Assets/Script/Test.cs:29)

问题解决：

需要在真机运行。
