Unity Action 是 Unity 引擎中的一种委托类型,它可以用来定义一个或多个没有参数和返回值的方法,以便在运行时动态地添加和移除这些方法,或者将它们用作事件的处理程序。Action 委托通常用于响应用户输入、游戏事件、物理碰撞等操作,可以使代码更加简洁、可读性更高,同时也方便了代码的维护和扩展。

unity action
Unity Action is a programming construct in Unity game engine that allows developers to define a set of actions or behaviors that can be triggered by certain events or inputs. Actions can be anything from playing an animation, moving an object, or executing a script.
Unity Actions are commonly used to create gameplay mechanics, such as shooting a weapon or jumping, as well as for user interface interactions, such as pressing a button or selecting an option from a menu.
Developers can define their own custom actions or use pre-built ones provided by Unity, such as the built-in UnityEvent system. Unity Actions are typically set up in the Unity Editor, using the Inspector window or scripting.
Overall, Unity Actions provide a flexible and powerful way to create interactive experiences in Unity games and applications.
unity Action传参
Unity中的Action是一种委托类型,可以用于定义不带参数和返回值的方法。如果需要在Action中传递参数,可以使用lambda表达式或者匿名方法来实现。
例如,定义一个Action类型的方法:
```csharp
public void DoSomething(Action<int> callback)
{
// 在这里调用callback,将一个int类型的参数传递给它
callback(42);
}
```
然后,在调用这个方法时,可以传递一个lambda表达式或者匿名方法:
```csharp
DoSomething((int result) =>
{
Debug.Log("The result is: " + result);
});
```
其中,lambda表达式 `(int result) => { Debug.Log("The result is: " + result); }` 接收一个int类型的参数,并在控制台输出结果。在方法内部,调用 `callback(42)` 时,会将参数 42 传递给lambda表达式,从而执行输出结果的操作。
