断言在表达式 go isactive () && 上失败go gettag() != 0 unity [英] assertion failed on expression go isactive () && go gettag () != 0 unity

问题描述

此错误对我的游戏开发无害，但时不时看到它会伤害我的眼睛.我怎样才能在 unity 上摆脱这个错误.

This error is harmless to my game development but it hurts my eye by seeing it from time to time . How can i get rid of this error on unity .

断言失败:断言在表达式上失败:'go.IsActive() &&go.GetTag() != 0'UnityEngine.Camera:get_main()

Assertion failed: Assertion failed on expression: 'go.IsActive() && go.GetTag() != 0'UnityEngine.Camera:get_main()

当我使用标签找到一个对象时它就出来了

It came out when i find an object using tag

public GameObject shadowUnderWater;

void OnEnable(){
  //uSkyManager Instantiates
    if(shadowUnderWater == null){
        shadowUnderWater = GameObject.FindGameObjectWithTag("SkyManager");
    }
}

到目前为止我所做的是:

What i did so far is this :

void Awake(){
  Camera.main.GetComponent<Camera> ();
}

我将相机设置为 Awake 功能，因为我在某些论坛上看到您只需要实例化相机.

I set the camera on the Awake function because i saw in some forum the you just need to instantiate the camera.

推荐答案

1. 无需获取相机组件
2. 如果相机为空，那么显然从中获取组件将失败
3. 你在 Awake 中所做的一切毫无意义，没有准备/获取相机的概念

这是您应该如何使用相机进行工作:

This is how you should do work involving your camera:

var cam = Camera.main;
if (cam != null)
{
    // do something
}
