Question

我复制了游戏的第1级。我想让它的工作方式与第1级相同，只需添加前一个。脚本和对撞机附加到预制件，其中对撞机功能用于同一脚本的两个类中。我在脚本中使用两个类。在我的游戏的第2级，我想调用第二个类，并希望脚本执行第二类的碰撞器功能。我怎样才能在二级打电话给二等？请帮我。谢谢。

public class class1: Monobehaviour {
//public variables declaration

void OnTriggerEnter2d(){}

}

public class class2: Monobehaviour {
//public variables declaration

void OnTriggerEnter2d(){}

}

Answer 1

您可以创建一个接口，让两个类实现相同的接口。

public interface ITriggerBehaviour
{
    void OnTriggerEnter2d();
}

public class class1: Monobehaviour, ITriggerBehaviour
{
    //public variables declaration

    void OnTriggerEnter2d(){}
}

public class class2: Monobehaviour, ITriggerBehaviour
{
    //public variables declaration
    void OnTriggerEnter2d(){}
}

然后，在不知道哪个类实现该方法的情况下，您可以使用相同的名称来调用它。

public void SomeOtherFunction()
{
    // In your code, the object will be provided elsewhere, in which case
    // you may want to use the 'as' operator to convert the object
    // reference to the interface and test for 'null' before using it.
    // This example shows that an interface can be used to hold a reference
    // to different types of object, providing they both implement the
    // same interface.
    ITriggerBehaviour someObject;
    if(currentLevel == 1)
        someObject = new class1();
    else
        someObject = new class2();

    // Call the method via the interface
    someObject.OnTriggerEnter2d();
}

在Unity中的c＃脚本中使用两个类
