在Unreal Engine中,代理分为单播delegate、多播delegate和动态delegate,其中单播delegate最为常用。使用代理首先要通过Unreal提供的宏声明委托,宏的选择取决于需要绑定方法的参数和返回值。声明后,会在类中创建一个代理变量,用于动态绑定符合声明签名的方法。绑定方法时需注意区分不同的Bind函数,例如Bind用于...
UDELEGATE 告诉UE这是一个可反射的delegate(很少用到) 宏的说明符 路径(\Engine\Source\Runtime\CoreUObject\Public\UObject\ObjectMacros.h) UCLASS 常用类说明符 Abstract:Abstract说明符会将类声明为"抽象基类",阻止用户向关卡中添加此类的Actor。对于单独存在时没有意义的类,此说明符非常有用。例如,`ATrigger...
Client 端在调用 BeginHandshake 的时候,会传入一个 Delegates,Handshake 完毕之后会调用 Delegates. Broadcast,通知握手完毕,绑定了该 Delegate 的接口都会被执行,大致如下: // 握手完毕的回调 voidUPendingNetGame::InitNetDriver(){ // 省略一些代码 // 发起握手,传入握手完毕的回调 ServerConn->Handler->BeginHan...
触发自定义事件,就像调用函数一样,直接调用即可,如果有参数,也可以像函数一样指定参数。 我们还可以动态的绑定将事件绑定到不同的调度器,就像高级编程语言中的Delegate一样。比如这样一个例子,我们按下K,为调度器绑定MyEvent,按下F,为调度器绑定MyEvent1,同样是调用同一个调度器,触发的行为是不同的。
先简单的使用一下Delegate(委托) 直接代码: 代理的声明,在开发中应该有一个专门用来委托的类。 1usingUnityEngine;2usingSystem.Collections;3publicclassDelegateTest : MonoBehaviour4{5publicdelegatevoidLogMessageDelegate(stringmessage);//委托的标识符就是delegate,LogMessageDelegate(string message)就是委托完毕后回...
