Unity点击器游戏购买后物品价值无法递增问题求助

我正在开发一款点击器游戏，设定购买物品时价格会递增，但实际只有首次购买时逻辑生效，后续能购买物品但价格不再上涨。尝试用布尔变量控制价值递增流程，未能解决问题。相关代码如下：

Buying 脚本 #

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

public class Buying : MonoBehaviour
{
    Click click;
    public Text boughtCoal;
    public float time = 1f;
    GameManager gameManager;
    public int whatYouWant;
    public float coalBought = 0;
    public float ValueIncrease;
    bool letValueIncrease = false;

    void Start(){
        click = GameObject.Find("Mine").GetComponent<Click>();
        gameManager = GameObject.Find("GameManager").GetComponent<GameManager>();
        ValueIncrease = 5;
    }
    public void OnClick(){
            click.money -= gameManager.coalCost;
            ValueIncrease = Mathf.Round(ValueIncrease * -10f) * 0.01f;
            coalBought += 1;
            letValueIncrease = true;
        
    }
    void Update(){
        time -= Time.deltaTime;
        if(time <= 0){
            click.money += coalBought;
            time += 1f;
        }
        boughtCoal.text = "Coal Bought: " + coalBought;
        if(letValueIncrease == true){
            ValueIncrease = gameManager.coalCost * 1.3f;
            letValueIncrease = false;
    }
    
   }
}

GameManager 脚本 #

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

public class GameManager : MonoBehaviour
{       
        Click click;
        Buying buying;

        public Text coalMiners;
        public Text ironMiners;
        public Text copperMiners;
        public Text goldMiners;
        
        public float coalCost;
        public float ironCost;
        public float copperCost;
        public float goldCost;

        public Button coalB;
        
    // Start is called before the first frame update
    void Start()
    {
        coalCost = 5;
        click = GameObject.Find("Mine").GetComponent<Click>();
        buying = GameObject.Find("Button").GetComponent<Buying>();
    }

    // Update is called once per frame
    void Update()
    {
        coalMiners.text = "Coal Miners: $" + buying.ValueIncrease;
        if(click.money < buying.ValueIncrease){
            coalB.interactable = false;
        }else{
            coalB.interactable = true;
        }
    }
}

Click 脚本 #

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

public class Click : MonoBehaviour
{   
    public Text moneyT;
    public float money;
    GameManager gameManager;
    // Start is called before the first frame update
    void Start()
    {
       
    }

    // Update is called once per frame
    void Update()
    {
         moneyT.text = "$$$: " + money;
    }

    void OnMouseDown(){
        money += 1;
    }
}

问题根源 #

1. 核心变量未更新：所有价格逻辑依赖gameManager.coalCost，但你从未修改这个变量，仅操作了ValueIncrease，导致价格一直停留在初始值5。
2. 冗余逻辑干扰：letValueIncrease布尔变量完全多余，将价格更新延迟到Update执行，反而造成逻辑混乱。
3. 错误计算逻辑：OnClick里的ValueIncrease = Mathf.Round(ValueIncrease * -10f) * 0.01f;是取反后四舍五入，完全不符合价格递增需求。

修复后的代码 #

Buying 脚本

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

public class Buying : MonoBehaviour
{
    Click click;
    public Text boughtCoal;
    public float time = 1f;
    GameManager gameManager;
    public float coalBought = 0;

    void Start(){
        click = GameObject.Find("Mine").GetComponent<Click>();
        gameManager = GameObject.Find("GameManager").GetComponent<GameManager>();
    }

    public void OnClick(){
        // 扣除当前购买价格
        click.money -= gameManager.coalCost;
        // 增加已购买数量
        coalBought += 1;
        // 更新下一次购买价格（上涨30%并取整）
        gameManager.coalCost = Mathf.Round(gameManager.coalCost * 1.3f);
    }

    void Update(){
        time -= Time.deltaTime;
        if(time <= 0){
            click.money += coalBought;
            time += 1f;
        }
        boughtCoal.text = "Coal Bought: " + coalBought;
    }
}

GameManager 脚本

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

public class GameManager : MonoBehaviour
{       
        Click click;
        Buying buying;

        public Text coalMiners;
        public Text ironMiners;
        public Text copperMiners;
        public Text goldMiners;
        
        public float coalCost;
        public float ironCost;
        public float copperCost;
        public float goldCost;

        public Button coalB;
        
    void Start()
    {
        coalCost = 5;
        click = GameObject.Find("Mine").GetComponent<Click>();
        buying = GameObject.Find("Button").GetComponent<Buying>();
    }

    void Update()
    {
        // 直接显示当前购买价格
        coalMiners.text = "Coal Miners: $" + coalCost;
        // 根据余额判断按钮可用性
        if(click.money < coalCost){
            coalB.interactable = false;
        }else{
            coalB.interactable = true;
        }
    }
}

Click 脚本（仅整理格式）

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

public class Click : MonoBehaviour
{   
    public Text moneyT;
    public float money;

    void Update()
    {
         moneyT.text = "$$$: " + money;
    }

    void OnMouseDown(){
        money += 1;
    }
}

修复说明 #

• 移除冗余的ValueIncrease和letValueIncrease，直接操作核心变量gameManager.coalCost。
• 在OnClick中直接完成价格递增计算，逻辑更直接，避免延迟执行的混乱。
• 修正价格计算逻辑，用Mathf.Round(gameManager.coalCost * 1.3f)实现每次购买后价格上涨30%并取整。
• 统一所有价格相关逻辑依赖coalCost，确保显示和判断逻辑一致。
