Unity之定时调用

1.Invoke(string methodName,float time)

在一定时间调用methodName函数

using UnityEngine;
using System.Collections;

public class example : MonoBehaviour {
    public Rigidbody projectile;
    void LaunchProjectile() {
        Rigidbody instance = Instantiate(projectile);
        instance.velocity = Random.insideUnitSphere * 5 ;
    }
    public void Awake() {
        Invoke( "LaunchProjectile" , 2 );
    }
}

2.InvokeRepeating(string methodName,float time,float repeatRate)

每隔一定时间调用一次methodName函数

 

Invokes the method methodName in time seconds.

在time秒调用methodName方法；简单说，根据时间调用指定方法名的方法

After the first invocation repeats calling that function every repeatRate seconds.

从第一次调用开始,每隔repeatRate时间调用一次.

using UnityEngine;
using System.Collections;

public class example : MonoBehaviour {
    public Rigidbody projectile;
    void LaunchProjectile() {
        Rigidbody instance = Instantiate(projectile);
        instance.velocity = Random.insideUnitSphere * 5 ;
    }
    public void Awake() {
        InvokeRepeating( "LaunchProjectile" , 2 , 0 .3F);  //2秒后，没0.3f调用一次
    }
}

3.CancelInvoke(string methodName)

取消这个脚本中所有的调用

 

Cancels all Invoke calls on this MonoBehaviour.

取消这个MonoBehaviour上的所有调用。

 

public class example : MonoBehaviour {
    public Rigidbody projectile;
    void Update() {
        if (Input.GetButton( "Fire1" ))
            CancelInvoke();

    }
    void LaunchProjectile() {
        instance = Instantiate(projectile);
        instance.velocity = Random.insideUnitSphere * 5 ;
    }
    public void Awake() {
        InvokeRepeating( "LaunchProjectile" , 2 , 0 .3F);
    }
}

function LaunchProjectile () {
    instance = Instantiate(projectile);
    instance.velocity = Random.insideUnitSphere * 5 ;
}

4.(bool) IsInvoking(string methodName)

 

using UnityEngine;
using System.Collections;

public class example : MonoBehaviour {
    public Rigidbody projectile;
    void Update() {
        if (Input.GetKeyDown(KeyCode.Space) && !IsInvoking( "LaunchProjectile" ))  //如果这个方法不在调用并且等待了2秒
            Invoke( "LaunchProjectile" , 2 );

    }
    void LaunchProjectile() {
        Rigidbody instance = Instantiate(projectile);
        instance.velocity = Random.insideUnitSphere * 5 ;
    }
}
