Component.GetComponent 获取组件

function GetComponent (type : Type) : Component

Description描述

Returns the component of Type type if the game object has one attached, null if it doesn't.

如果游戏物体有一个附加，则返回Type类型的组件，如果没有则为null。

C# users can use a generic version.

C#用户可以使用普通的版本。

using UnityEngine;
using System.Collections;

public class example : MonoBehaviour {
	public Transform curTransform;
	void Start() {
		ExampleScript someScript;
		someScript = GetComponent<ExampleScript>();
		someScript.DoSomething();
	}
	public void Awake() {
		curTransform = GetComponent<Transform>();
	}
}

// Equivalent to: Transform curTransform = transform;
//等同于变换 curTransform = transform
var curTransform : Transform;
curTransform = GetComponent (Transform);

// You can access script components in the same way as other components.
//你可以像其他组件一样访问脚本组件
function Start () {
	var someScript : ExampleScript;
	someScript = GetComponent (ExampleScript);
	someScript.DoSomething ();
}

• function GetComponent (type : string) : Component

Description描述

Returns the component with name type if the game object has one attached, null if it doesn't.

如果游戏物体有一个附加，则返回名字类型组件，如果没有则为null。

It is better to use GetComponent with a Type instead of a string for performance reasons. Sometimes you might not be able to get to the type however, for example when trying to access a C# script from Javascript. In that case you can simply access the component by name instead of type. Example:

由于性能原因，最好使用Type的GetComponent，而不是用字符串。不过有时你可能无法得到Type，例如当你从Javascript访问C#脚本时，这个时候你可以简单通过名字而不是type来访问组件。例如：

using UnityEngine;
using System.Collections;

public class example : MonoBehaviour {
	public ScriptName script;
	public void Awake() {
		script = GetComponent("ScriptName") as ScriptName;
		script.DoSomething();
	}
}

// To access public variables and functions in another script attached to the same game object.
//访问另一个脚本附加到一样的游戏物体的公共变量和函数
var script : ScriptName;
script = GetComponent("ScriptName");
script.DoSomething ();
