当我有3个相同的物体时，只有一个游戏物体会统一移动

问题描述

这已经让我很烦了一段时间，但找不到解决方案。只有ground3移动，而其他2保持原位。我正在团结一致地进行2D项目。

代码：

using System.Collections.Generic;
using UnityEngine;

public class GroundMovement : MonoBehavIoUr
{
    public float globalspeed;

    public GameObject Ground1;
    public float Ground1Speed;
    Rigidbody2D rb1;

    public GameObject Ground2;
    public float Ground2Speed;
    Rigidbody2D rb2;

    public GameObject Ground3;
    public float Ground3Speed;
    Rigidbody2D rb3;


    // Start is called before the first frame update
    void Start()
    {
        rb1 = Ground1.GetComponent<Rigidbody2D>();
        rb2 = Ground1.GetComponent<Rigidbody2D>();
        rb3 = Ground1.GetComponent<Rigidbody2D>();
    }

    // Update is called once per frame
    void Update()
    {
        rb1.veLocity = new Vector2(globalspeed + Ground1Speed,0);
        rb2.veLocity = new Vector2(globalspeed + Ground2Speed,0);
        rb3.veLocity = new Vector2(globalspeed + Ground3Speed,0);
    }
}

解决方法

问题出在Start()方法中，当您分配刚体时，您将它们全部分配给了Ground1 GameObject中的刚体，该方法应如下所示：

void Start()
{
    rb1 = Ground1.GetComponent<Rigidbody2D>();
    rb2 = Ground2.GetComponent<Rigidbody2D>();
    rb3 = Ground3.GetComponent<Rigidbody2D>();
}
