Description

public function GetComponent(type: string): Component;
public Component GetComponent(string type);
public def GetComponent(type as string) as Component

Description

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

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:

// Disable the spring on the HingeJoint component.

var hinge : HingeJoint; hinge = GetComponent("HingeJoint"); hinge.useSpring = false;
using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour {
    public HingeJoint hinge;
    void Example() {
        hinge = GetComponent("HingeJoint") as HingeJoint;
        hinge.useSpring = false;
    }
}
import UnityEngine
import System.Collections

public class ExampleClass(MonoBehaviour):

	public hinge as HingeJoint

	def Example() as void:
		hinge = (GetComponent('HingeJoint') as HingeJoint)
		hinge.useSpring = false
