在游戏设计过程中定时器是必不可少的工具,我们知道update方法是MonoBehavior中一个人人皆知的定时器方法,每帧都在调用,那还有其他什么定时器的方法呢,这里介绍一下。
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.

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)
某指定函数是否在等候调用

(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; } } |
