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 ();

}

o 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 ();
