GameObject.GetComponentsInChildren

Parameters

Description

返回 GameObject 或其任何子项中类型为 type 的所有组件。

Unity searches for components recursively on child GameObjects. This means that it also includes all the child GameObjects of the target GameObject, and all subsequent child GameObjects.
Note: If the type you request is a derivative of MonoBehaviour and the associated script can not be loaded then this function will return `null` for that component.

using UnityEngine;

public class GetComponentsInChildrenExample : MonoBehaviour
{
    void Start()
    {
        Component[] hingeJoints;

        hingeJoints = GetComponentsInChildren(typeof(HingeJoint));

        if (hingeJoints != null)
        {
            foreach (HingeJoint joint in hingeJoints)
                joint.useSpring = false;
        }
        else
        {
            // Try again, looking for inactive GameObjects
            Component[] hingesInactive = GetComponentsInChildren(typeof(HingeJoint), true);

            foreach (HingeJoint joint in hingesInactive)
                joint.useSpring = false;
        }
    }
}

Parameters

Returns

T[] 匹配指定类型的所有已发现组件的列表。

Note: If the type you request is a derivative of MonoBehaviour and the associated script can not be loaded then this function will return `null` for that component.

using UnityEngine;

public class GetComponentsInChildrenExample : MonoBehaviour
{
    void Start()
    {
        HingeJoint[] hingeJoints;

        hingeJoints = GetComponentsInChildren<HingeJoint>();

        if (hingeJoints != null)
        {
            foreach (HingeJoint joint in hingeJoints)
                joint.useSpring = false;
        }
        else
        {
            // Try again, looking for inactive GameObjects
            HingeJoint[] hingesInactive = GetComponentsInChildren<HingeJoint>(true);

            foreach (HingeJoint joint in hingesInactive)
                joint.useSpring = false;
        }
    }
}

Parameters

Description

将找到的所有组件均返回到 List results 中。

Note: If the type you request is a derivative of MonoBehaviour and the associated script can not be loaded then this function will return `null` for that component.

using UnityEngine;
using System.Collections.Generic;


public class GetComponentsInChildrenExample : MonoBehaviour
{
    void Start()
    {
        List<HingeJoint> hingeJoints = new List<HingeJoint>();

        GetComponentsInChildren<HingeJoint>(false, hingeJoints);

        if (hingeJoints != null)
        {
            foreach (HingeJoint joint in hingeJoints)
                joint.useSpring = false;
        }
        else
        {
            // Try again, looking for inactive GameObjects
            List<HingeJoint> hingesInactive = new List<HingeJoint>();

            GetComponentsInChildren<HingeJoint>(true, hingesInactive);

            foreach (HingeJoint joint in hingesInactive)
                joint.useSpring = false;
        }
