public Component GetComponentInChildren (Type type);
public Component GetComponentInChildren (Type type, bool includeInactive);

参数

type 要检索的组件的类型。

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; } } }

public T GetComponentInChildren (bool includeInactive= false);

返回

T 匹配类型的组件(如果找到)。

描述

Generic version of this method.

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<HingeJoint>();

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

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