GameObject.GetComponent

パラメーター

説明

ゲームオブジェクトに type がアタッチされている場合は type のタイプを使用してコンポーネントを返します。ない場合は null です

Using gameObject.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 gameObject.GetComponents instead, and cycle through the returned components testing for some unique property.

using UnityEngine;

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

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

説明

Generic version of this method.

using UnityEngine;

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

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

説明

ゲームオブジェクトに type がアタッチされている場合は type の名前を使用してコンポーネントを返します。ない場合は null です

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.

using UnityEngine;

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

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