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 ; } }
