Unity怎样才能AddComponent< T>()? [英] Unity how can AddComponent<T>()?

问题描述

我需要将特定脚本附加到GameObject.

I need to attach a specific script to a GameObject.

public T ElegirScript<T>()
    {
        switch((int)tipoEdificio)  // enum
        {
        case 0:

            return Edificios;  // a class/script not instance
            break;
        case 1:

            return PlantaEnergia;  // a class/script not instance
            break;
        default:
            break;
        }
    }


gameobject.AddComponent<ElegirScript()>();

我该怎么做?我有错误，谢谢.

How can I make this? I have errors, thanks.

我首先需要一个返回类型或组件的方法，返回的必须是脚本.然后我添加组件并提供程序选择的类型，我该怎么做?例子.

I need first a Method that returns a type or a component, the return must be scripts. then I AddComponent and give the type the program choose, How can I do this? Examples.

推荐答案

您不能将非组件类型的类与添加"组件一起使用.这意味着您的类必须继承自MonoBehaviour，才能添加到gameObject中.其次，那不是您最初如何使用泛型的方法.如果您只是想基于一个条件来添加其他组件，那么即使对泛型也感到困扰的只是尝试:

You cant use a non component type class with Add component. Meaning that your class has to inherit from MonoBehaviour to be able to be added to a gameObject. And secondly thats not how you use generics in the first place. IF you just want to add a different component bases on a condition why even bother with generics just try :

if(condition)
gameObject.AddComponent<MyMonoBehaviourClass1>();
else
gameObject.AddComponent<MyMonoBehaviourClass2>();

我终于设法完成了Op想要的工作，但是同意了它不是通用的解决方案. 可以选择OP代码:

I finally managed to do what Op wanted but granted its not a generic solution. Chages to OP code :

public Type ElegirScript()
    {
        switch ((int)tipoEdificio)  // enum
        {
            case 0:
                return typeof(Edificios);  // a class/script not instance
            case 1:
                return typeof(PlantaEnergia);  // a class/script not instance
            default:
                return null;//Or throw exception here
        }
    }

现在您可以调用gameObject.AddComponent(ElegirScript());，它可以正常工作.

Now you can call gameObject.AddComponent(ElegirScript()); and it works just fine.
