Component.GetComponentInParent

切换到手册
public Component GetComponentInParent (Type t);
public Component GetComponentInParent (Type t, bool includeInactive);

参数

t The type of Component to retrieve.
includeInactive 在发现结果集内是否应包含非活动 GameObject 上的组件?

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; } } }

public T GetComponentInParent ();
public T GetComponentInParent (bool includeInactive= false);

参数

includeInactive 在发现结果集内是否应包含非活动 GameObject 上的组件?

返回

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

描述

Generic version of this method.

using UnityEngine;

public class GetComponentInParentExample : MonoBehaviour { void Start() { HingeJoint hinge = GetComponentInParent<HingeJoint>();

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

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