typeThe type of Component to retrieve.

public class ScriptExample : MonoBehaviour { void Start() { // Disable the spring on the HingeJoint component. HingeJoint hinge = GetComponent<HingeJoint>(); hinge.useSpring = false; } }

public T GetComponent();

Description

public Component GetComponent(string type);

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:

using UnityEngine;

public class ScriptExample : MonoBehaviour { void Start() { // Disable the spring on the HingeJoint component. HingeJoint hinge = GetComponent("HingeJoint") as HingeJoint; hinge.useSpring = false; } }
