Component.GetComponentInParent

参数

返回

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

描述

Returns the Component of type in the GameObject or any of its parents.

Unless a Component of type is found in the current GameObject, the method recurses upwards until it finds a GameObject with a matching Component.// Only Components on active GameObjects are matched unless explicitly specified otherwise.

using UnityEngine;

public class GetComponentInParentExample : MonoBehaviour
{
    void Start()
    {
        HingeJoint hinge = GetComponentInParent(typeof(HingeJoint)) as HingeJoint;

        if (hinge != null)
        {
            hinge.useSpring = false;
        }
        else
        {
            // Try again by including inactive GameObjects.
            hinge = GetComponentInParent(typeof(HingeJoint), true) as HingeJoint;

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