Component.GetComponentInChildren

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 children using depth first search.

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

using UnityEngine;

public class GetComponentInChildrenExample : MonoBehaviour
{
    void Start()
    {
        HingeJoint hinge = GetComponentInChildren(typeof(HingeJoint)) as HingeJoint;

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

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

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

        if (hinge != null)
        {

        }
        else
        {
            // Try again by including inactive GameObjects.
            hinge = GetComponentInChildren<HingeJoint>(true);
