1.製作插旗時的揚塵特效

2.部署插旗特效並建立數字元素類和陷阱元素類

建立NumberElement和TrapElement類，分析需要重寫的方法。

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

public class NumberElement : SingleCoveredElement {

    public override void Awake()
    {
        base.Awake();
        elementState = ElementState.Covered;
        elementContent = ElementContent.Number;
    }

    public override void OnMiddleMouseButton()
    {
        
    }

    public override void UncoverElementSingle()
    {
        
    }

    public override void OnUnCovered()
    {
        
    }
}
 

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

public class TrapElement : SingleCoveredElement {

    public override void Awake()
    {
        base.Awake();
        elementState = ElementState.Covered;
        elementContent = ElementContent.Trap;
    }

    public override void UncoverElementSingle()
    {

    }

    public override void OnUnCovered()
    {

    }
}
 

3.設計數字元素類的功能

首先在基類BaseElement新增ClearShadow方法

    public void ClearShadow()
    {
        Transform shadow = transform.Find("shadow");
        if(shadow != null)
        {
            Destroy(shadow.gameObject);
        }
    }

完善數字元素類功能並分析後面要實現的功能

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

public class NumberElement : SingleCoveredElement {

    public override void Awake()
    {
        base.Awake();
        elementState = ElementState.Covered;
        elementContent = ElementContent.Number;
    }

    public override void OnMiddleMouseButton()
    {
        //TODO 檢查八領域並翻開
    }

    public override void UncoverElementSingle()
    {
        if (elementState == ElementState.Uncovered) return;
        RemoveFlag();
        elementState = ElementState.Uncovered;
        ClearShadow();
        //TODO 顯示泥土翻開的特效
        //TODO 計算並顯示自身數字
    }

    public override void OnUnCovered()
    {
        //TODO 泛洪演算法翻開周邊的元素
    }
}
 

4.設計陷阱元素類的功能

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

public class TrapElement : SingleCoveredElement {

    public override void Awake()
    {
        base.Awake();
        elementState = ElementState.Covered;
        elementContent = ElementContent.Trap;
    }

    public override void UncoverElementSingle()
    {
        if (elementState == ElementState.Uncovered) return;
        RemoveFlag();
        elementState = ElementState.Uncovered;
        ClearShadow();
        //TODO 顯示泥土翻開的特效
        LoadSprite(GameManager._instance.trapSprites[Random.Range(0, GameManager._instance.trapSprites.Length)]);
    }

    public override void OnUnCovered()
    {
        //TODO 翻開所有雷
    }
}

5.製作並部署泥土翻開特效

根據之前做過的揚塵特效製作泥土特效，然後建一個自動銷燬的指令碼

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

public class AutoDestroy : MonoBehaviour {

    public float delay;

    private void Start()
    {
        Destroy(gameObject, delay);
    }
}

然後部署泥土的特效

public GameObject uncoveredEffect;

Instantiate(GameManager._instance.uncoveredEffect, transform);

6.設計地圖的初始化方案

分析地圖初始化方案，建立儲存可用索引值的列表

    private void InitMap()
    {
        //可用索引值的列表
        List<int> availabaleIndex = new List<int>();
        for(int i = 0; i < w * h; i++)
        {
            availabaleIndex.Add(i);
        }
    }

7.設計地址轉換方法與元素轉換方法

設計一維索引值和二維索引值相互轉換的方法以及生成陷阱的方法

    /// <summary>
    /// 生成陷阱
    /// </summary>
    /// <param name="availableIndex">尚未初始化的地圖元素的索引值</param>
    private void GenerateTrap(List<int> availableIndex)
    {
        float trapProbability = Random.Range(minTrapProbability, maxTrapProbability);
        int trapNum = (int)(availableIndex.Count * trapProbability);
        for(int i = 0; i < trapNum; i++)
        {
            int tempIndex = availableIndex[Random.Range(0, availableIndex.Count)];
            int x, y;
            GetPosition(tempIndex, out x, out y);
            availableIndex.Remove(tempIndex);
        }
    }


    private BaseElement SetElement(int index,ElementContent content)
    {
        return null;
    }
    /// <summary>
    /// 將給定的一維索引值轉換為二維索引值
    /// </summary>
    /// <param name="index">給頂的一維索引值</param>
    /// <param name="x">轉換後的二維索引值的x</param>
    /// <param name="y">轉換後的二維索引值的y</param>
    private void GetPosition(int index,out int x,out int y)
    {
        y = index / w;
        x = index - y * w;
    }

    /// <summary>
    /// 將給定的二維索引值轉換為一維索引值
    /// </summary>
    /// <param name="x">二維索引值的x</param>
    /// <param name="y">二維索引值的y</param>
    /// <returns></returns>
    private int GetIndex(int x,int y)
    {
        return w * y + x;
    }
