GameObject.GetComponentInChildren

参数

返回

Component 匹配类型的组件（如果找到）。

描述

使用深度首次搜索返回 GameObject 或其任何子项中类型为 type 的组件。

仅当在活动 GameObject 上发现组件时才返回该组件。

using UnityEngine;

public class GetComponentInChildrenExample : MonoBehaviour
{
    // Disable the spring on the first HingeJoint component found on any child object

    void Start()
    {
        HingeJoint hinge = gameObject.GetComponentInChildren(typeof(HingeJoint)) as HingeJoint;

        if (hinge != null)
            hinge.useSpring = false;
        else
        {
            // Try again, looking for inactive GameObjects
            HingeJoint hingeInactive = gameObject.GetComponentInChildren(typeof(HingeJoint), true) as HingeJoint;

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

返回

T 匹配类型的组件（如果找到）。

        else
        {
            // Try again, looking for inactive GameObjects
            HingeJoint hingeInactive = gameObject.GetComponentInChildren<HingeJoint>(true) as HingeJoint;

            if (hingeInactive != null)
                hingeInactive.useSpring = false;
