1 unity里的 Debug.log相关

除了常用的 Debug.Log，还有另外2个

•     Debug.Log("Debug.Log");
•     Debug.LogWarning("Debug.LogWarning");
•     Debug.LogError("Debug.LogError");

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class debugTest : MonoBehaviour
{// Start is called before the first frame updatevoid Start(){Debug.Log("Debug.Log");Debug.LogWarning("Debug.LogWarning");Debug.LogError("Debug.LogError");}// Update is called once per framevoid Update(){}
}

2 用Debug.DrawLine 和  Debug.DrawRay画线

2.1 画线

• Debug.DrawLine(new Vector3(290,90,100),new Vector3(290,100,100),Color.blue);
• DrawLine( 起点坐标，终点坐标)

• Debug.DrawRay(new Vector3(290,90,100),new Vector3(290,100,100),Color.red);
• DrawRay( 起点坐标，方向)
• 其实方向，也就是这里的Vector3(290,100,100) 是指
• Vector3(0,0,0) 到Vector3(290,100,100)的方向，把起点从Vector3(0,0,0)挪到Vector3(290,90,100)这里来形成的一个新射线
• 这么详细解释下
• step1: 有一个向量Vector3(290,100,100), 画出来，Vector3(0,0,0) → 指向Vector3(290,100,100), 图上的红色箭头
• step2:然后把这个向量挪动，方向不变，起点挪动到Vector3(290,90,100) 这里来,生成了图上红色的细线

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class debugTest : MonoBehaviour
{// Start is called before the first frame updatevoid Start(){Debug.Log("Debug.Log");Debug.LogWarning("Debug.LogWarning");Debug.LogError("Debug.LogError");}// Update is called once per framevoid Update(){Debug.DrawLine(new Vector3(290,90,100),new Vector3(290,100,100),Color.blue);Debug.DrawRay(new Vector3(290,90,100),new Vector3(290,100,100),Color.red);}
}

2.2 调试的东西只会出现scene窗口，不会出现在game窗口
