Question

编写一个稍后将链接到按钮的脚本。此脚本将检查是否已购买该项目，如果没有，则允许购买而不是一些基本数学。不知道为什么但是在每个函数的同一行我得到了错误。它通常是if语句的第一行。这是：

Assets / Scripts / purchaseScript.cs（25,51）：错误CS0119：表达式表示type', where a变量'，value' or方法组'是预期的

这是脚本。

using UnityEngine;
using System.Collections;

public class purchaseScript : MonoBehaviour {

    //Imported Scripts
    public cameraspeed cs;

    //prices
    public int greenBallPrice = 100;
    public int blueBallPrice = 100;

    public int pinkBallPrice = 350;
    public int rainbowBallPrice = 1000;

    public int yingyangBallPrice = 1800;
    public int hashtagBallPrice = 2000;
    public int oceanBallPrice = 2400;
    public int speakerBallPrice = 2400;

Answer 1

在第一个if语句中，看起来好像你想要改变

balance == blueBallPrice

到

cs.balance == blueBallPrice

与其他if语句相同/相似

错误CS0119：表达式表示“类型”，其中需要“变量”，“值”或“方法组”
