脚本应该将玩家 A 传送到玩家 B，反之亦然（交换角色的位置），但只将其中一个传送到另一个之上

Question

我对 Unity 和 C# 一点经验都没有。这段代码看起来是正确的。我真的不知道我需要在这里放什么来提供更多上下文，所以如果需要的话我会这样做

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

namespace ModScripts
{
    public class TeleporterScript : MonoBehaviour, IUseItem
    {
        public float maxRange = 5f;

        [SerializeField]
        private GameObject playerObject;
        private Collider[] colliders;
        private GameObject target;
        private float distancia;

        // UseItem executes right when player presses a specific key on keyboard
        public void UseItem(Transform position, Quaternion rotation)
        {
            // playerObject is supposed to be the player that used the item
            playerObject = position.gameObject;
            Instantiate(gameObject, position.position, rotation);
            CheckCollider();
        }

        void CheckCollider()
        {
            // Check the players using colliders
            // layer 15 is player A
            // layer 16 is player B
            int layerMask = (1 << 15) | (1 << 16);

            // Physics.OverlapSphere to make a limited range around the player
            colliders = Physics.OverlapSphere(transform.position, maxRange, layerMask);

            // Calculate distance between colliders[]
            foreach (Collider collider in colliders)
            {
                if (collider.gameObject.layer != playerObject.layer)
                {
                    // Calculate distance
                    distancia = Vector3.Distance(playerObject.transform.position, collider.transform.position);
                    
                    // If distance is bigger than maxRange
                    if (distancia > maxRange)
                    {
                        break;
                    }
                    else
                    {
                        // Teleport to target
                        target = collider.gameObject;                        
                        Teleport(target);
                    }
                }
            }
        }                  

        void Teleport(GameObject target)
        {
            // Debug.Log says the intended target
            Debug.Log(target.name);
            float elevation = 0f;

            // Get velocity of both karts
            Vector3 currentVelocity = playerObject.GetComponent<Rigidbody>().velocity;
            Vector3 targetVelocity = target.GetComponentInParent<Rigidbody>().velocity;

            // Switch positions between kart that used item and target
            Vector3 tempPosition = new Vector3(playerObject.transform.position.x, playerObject.transform.position.y + elevation, playerObject.transform.position.z);           
            playerObject.transform.position = new Vector3(target.transform.position.x, target.transform.position.y + elevation, target.transform.position.z);
            target.transform.position = tempPosition;
            
            // Maintain velocity of karts
            playerObject.GetComponent<Rigidbody>().velocity = currentVelocity;
            target.GetComponentInParent<Rigidbody>().velocity = targetVelocity;
        }
    }
}

上面的代码按预期将使用物品的玩家传送到另一个玩家的位置。然而，另一位玩家没有改变位置，导致一个玩家在另一个玩家之上。如果它有任何重要性，我正在使用 unity kartgame 演示。

Answer 1

target.GetComponentInParent<Rigidbody>()

你从父级获取刚体，所以

target

不是目标的根对象，你需要移动根对象而不是这个

target

.

var targetRigidbody = target.GetComponentInParent<Rigidbody>();
targetRigidbody.transform.position = tempPosition;
