错误 CS1061：“GameObject”不包含“localPosition”的定义

Question

H，我要开发一个带有 unity 的拖放游戏但是出现这个错误，请问如何解决这个错误！

这是完整的错误 （错误 CS1061：“GameObject”不包含“localPosition”的定义，并且找不到接受“GameObject”类型的第一个参数的可访问扩展方法“localPosition”（您是否缺少 using 指令或程序集引用？））

这是我在 C# 脚本中的代码

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

public class MoveSystem : MonoBehaviour
{

    public GameObject correctForm; 
    
    private bool moving; // to check if it is moving or not 
    private float startPosX; 
    private float startPosY; 


    // Start is called before the first frame update
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
        if(moving){
            Vector3 mousePos; 
            mousePos= Input.mousePosition; 
            mousePos = Camera.main.ScreenToWorldPoint(mousePos); 

            this.gameObject.transform.localPosition = new Vector3(mousePos.x - startPosX, mousePos.y - startPosY, this.gameObject.localPosition.z);
        }
        
    }


    public void OnMouseUp(){

        moving = false; 

    } 


    public void OnMouseDown(){

        if (Input.GetMouseButtonDown(0))
        {
            Vector3 mousePos; 
            mousePos = Input.mousePosition;
            mousePos = Camera.main.ScreenToWorldPoint(mousePos); 

            startPosX = mousePos.x - this.transform.localPosition.x;
            startPosY = mousePos.y - this.transform.localPosition.y; 

            moving = true; 

        }
    }
}
 

Answer 1

在更新函数中，在最后一行的最后一个参数中，您输入了this.gameObject.localPosition.z。 GameObject 没有名为 localPosition 的字段。您应该通过this.gameObject.transform.localPosition.z 修复它。总之，您的更新应如下所示：

// Update is called once per frame
void Update()
{
    if(moving){
        Vector3 mousePos; 
        mousePos= Input.mousePosition; 
        mousePos = Camera.main.ScreenToWorldPoint(mousePos); 

        this.gameObject.transform.localPosition = new Vector3(mousePos.x - startPosX, mousePos.y - startPosY, this.gameObject.transform.localPosition.z);
    }
    
}
