  • 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;
        }
    }
