public Component GetComponent (Type type);

パラメーター

type The type of Component to retrieve.

戻り値

Component A Component of the matching type, otherwise null if no Component is found.

説明

Returns the component of type if the GameObject has one attached.

Component.GetComponent will return the first component that is found and the order is undefined. If you expect there to be more than one component of the same type, use Component.GetComponents instead, and filter that output further.// To get a component on a different GameObject, use GameObject.Find to get a reference to the other GameObject, and then use GameObject.GetComponent on the other GameObject.

using UnityEngine;

public class GetComponentExample : MonoBehaviour { void Start() { HingeJoint hinge = gameObject.GetComponent(typeof(HingeJoint)) as HingeJoint;

if (hinge != null) hinge.useSpring = false; } }

public T GetComponent ();

戻り値

T A Component of the matching type, otherwise null if no Component is found.

説明

Generic version of this method.

using UnityEngine;

public class GetComponentExample : MonoBehaviour { void Start() { HingeJoint hinge = GetComponent<HingeJoint>();

if (hinge != null) hinge.useSpring = false; } }

public Component GetComponent (string type);

パラメーター

type The name of the type of Component to get.

戻り値

Component A Component of the matching type, otherwise null if no Component is found.

説明

To improve the performance of your code, consider using GetComponent with a type instead of a string.

using UnityEngine;

public class GetComponentExample : MonoBehaviour { void Start() { HingeJoint hinge = GetComponent("HingeJoint") as HingeJoint;

if (hinge != null) hinge.useSpring = false; } }
