GameObject.GetComponentsInParent

Parameters

Description

返回 GameObject 或其任何父项中类型为 type 的所有组件。

The search for components is carried out recursively on parent objects, so it includes parents of parents, and so on.
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 GetComponentsInParentExample : MonoBehaviour
{
    void Start()
    {
        Component[] hingeJoints;

        hingeJoints = GetComponentsInParent(typeof(HingeJoint));

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

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

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 GetComponentsInParentExample : MonoBehaviour

    {
        HingeJoint[] hingeJoints;

        hingeJoints = GetComponentsInParent<HingeJoint>();

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

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

Parameters

Description

查找 GameObject 或父项中的组件，然后将它们返回到 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 GetComponentsInParentExample : MonoBehaviour
{
    void Start()
    {
        List<HingeJoint> hingeJoints = new List<HingeJoint>();

        GetComponentsInParent<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>();

            GetComponentsInParent<HingeJoint>(true, hingesInactive);

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