Basic syntax of unity script (8) - collaborative program and destruction method

Collaborative process

   Collaborative process , That is to say The main program Start while running Another logic processing to coordinate the execution of the current program . But it is different from multithreaded programs , All cooperative programs are run in the main program , It is also a single threaded program . stay Unity Through StartCoroutine Method to start collaboration .
  StartCoroutine Method is MonoBehavior A method in class , That is, the method must be in MonoBehavior Or inherit from MonoBehavior Call in class .StartCoroutine Method can return a value of IEnumerator As a parameter

void Start()
	{
    
		StartCoroutine(doThing1());// Turn on doThing1 Collaborative process 
	}
	IEnumerator doThing1()// Statement doThing Method 
	{
    
		yield return StartCoroutine(doThing2());// Turn on doThing2 Collaborative process 
	}
	IEnumerator doThing2()
	{
    
		yield return new WaitForSeconds(2);// Cooperative program sleep 2s
	}

Methods related to destruction

   In the process of game development , I often meet people 、 Components 、 Resources, etc. lose their function after use , If you let it go , At least, it will affect the operation efficiency of the project , More importantly, it may affect the normal operation of the project . therefore , There must be a way to manage 、 Delete these useless resources .

Different functions Destroy Method

function	function
Object.Destroy	Delete game objects 、 Component or resource
NetWork.Destroy	Destroy network objects
MonoBehavior.OnDestroy	Called when the script is destroyed

Object.Destroy Method

Object.Destroy Method can destroy the object immediately , You can also set the time to destroy . If the deleted object is a component , Then the component will be removed .

	public GameObject obj;
	void Start()
	{
    
		Destroy(obj.GetComponent<Rigidbody>());// Destroy rigid body components of game objects 
		Destroy(obj, 5);//5s Delete after obj The game object 
	}

NetWork.Destroy Method

NetWork.Destroy Method can destroy network objects , This object can be overloaded in two ways

public static void Destroy(NetworkViewID viewID)
public static void Destory(Gameobject gameobject)
1、 The system will delete all and the ViewID Related objects 
2、 Destroy game objects on the network 

Network.Destory(GetComponent<NetworkView>().viewID)
Network.Destory(gameobject)

MonoBehaviour.OnDestroy Method

MonoBehaviour.OnDestroy The method is MonoBehaviour Destroy callback method in
