Unity Boot Event-listener: Initializeonload

[initializeonload]: Run the editor script official case when you start unity:

  
 

   
  

  
using UnityEngine; 
   
  

  
using UnityEditor; 
   
  

  
 
   
  

  
[InitializeOnLoad] 
   
  

  
public class Startup { 
   
  

  
 static Startup() 
   
  

  
 { 
   
  

  
 Debug.Log("Up and running"); 
   
  

  
 } 
   
  

  
} 
  
 

Print a word when you start Unity.
e.g. Siki:

  
 

   
  

  
using UnityEditor;
   
  

  
using UnityEngine;
   
  

  

   
  

  
[InitializeOnLoad]
   
  

  
public class Appload
   
  

  
{
   
  

  
 static Appload()
   
  

  
 {
   
  

  
 bool hasKey = PlayerPrefs.HasKey("sikiwelcomescreen");
   
  

  
 if (hasKey==false)
   
  

  
 {
   
  

  
 //EditorApplication.update += Update;
   
  

  
 PlayerPrefs.SetInt("sikiwelcomescreen", 1);
   
  

  
 WelcomeScreen.ShowWindow();
   
  

  
 }
   
  

  
 }
   
  

  

   
  

  
 //static void Update() 
   
  

  
 //{
   
  

  
 // bool isSuccess = EditorApplication.ExecuteMenuItem("Welcome Screen");
   
  

  
 // if (isSuccess) EditorApplication.update -= Update;
   
  

  
 //}
   
  

  
}
