Component.GetComponent

パラメーター

説明

Returns the component of Type type if the GameObject has one attached, null if it doesn't. Will also return disabled components.

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 cycle through the returned components testing for some unique property.

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 ScriptExample : MonoBehaviour
{
    void Start()
    {
        // Disable the spring on the HingeJoint Component.
        HingeJoint hinge = gameObject.GetComponent(typeof(HingeJoint)) as HingeJoint;
        hinge.useSpring = false;
    }
}

説明

Generic version of this method.

using UnityEngine;

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

説明

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

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

using UnityEngine;

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