c# - "The type or namespace name could not be found. Are you missing assembly reference ?"统一错误

Question

我试图在鼠标悬停在对象上时显示 GUI 标签，而当鼠标光标从对象上移开时标签会隐藏。

谁能告诉我为什么会出现错误？

using UnityEngine;
using System.Collections;

public class label_diet : MonoBehaviour {
    public showGUI boolean = false;
    void OnMouseOver()
    {
        showGUI = true;
    }

    void OnMouseExit()
    {
        showGUI = false;
    }

    void OnGUI()
    {
        if (showGUI)
        {
            GUI.Label(new Rect(10, 10, 100, 20), "You are selecting Diet coke");
        }
    }
}

Answer 1

更改行

public showGUI boolean = false;

到

public bool showGUI = false; //for C#
public var showGUI = false; //for JS, but you're using C#

那应该没问题；如果不是，请检查脚本是否附加到 UI 对象或具有碰撞器组件的对象。
