Question

我正在按照youtube上的教程在Unity中制作游戏

这是视频的链接，它将在他编写此代码Link

时开始

当我进入另一个房间时，它只是显示和消失的文本如果需要文本，则OnTriggerEnter2D调用StartCoroutine

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

public class RoomMove : MonoBehaviour
{
    public Vector2 cameraChange;
    public Vector3 playerChange;
    private CameraMovment cam;
    public bool needText;
    public GameObject text;
    public Text placeText;
    public string placeName;

    // Start is called before the first frame update
    void Start()
    {
        cam = Camera.main.GetComponent<CameraMovment>();

    }

    // Update is called once per frame
    void Update()
    {

    }
    private void OnTriggerEnter2D(Collider2D collision)
    {
        if(collision.CompareTag("Player"))
        {
            cam.minPosition += cameraChange;
            cam.maxPosition += cameraChange;
            collision.transform.position += playerChange;

            if(needText)
            {
                StartCoroutine(placeNameCo);
            }
        }
    }
    private IEnumerator placeNameCo()
    {
        text.SetActive(true);
        placeText = placeName;
        yield return new WaitForSeconds(4f);
        text.SetActive(false);
    }
}

我遇到2个错误：

Error   CS1503  Argument 1: cannot convert from 'method group' to 'string'  Assembly-CSharp 

Error   CS0029  Cannot implicitly convert type 'string' to 'UnityEngine.UI.Text'    Assembly-CSharp

Answer 1

placeText是整个Text Component，所以您想将字符串分配给它的text property，例如：

placeText.text = placeName;

此外，StartCoroutine需要参数中的例程或字符串。因此，将第38行替换为：

StartCoroutine(placeNameCo())或StartCoroutine("placeNameCo")

首选第一个，因为字符串版本启动协程的运行时开销较高，并且您只能传递一个参数。

无法将类型字符串隐式转换为“ UnityEngine.UI.Text”
