  思路

  1、每个形状都是由4个“块”组成也就是“块”是俄罗斯方块最小单位首先要有个“块”用户Control控件要求可以设置“块”位置和颜色

  2、经典俄罗斯方块共7种形状把每种形状所需要功能抽象出来写个抽象类7个具体形状分别继承这个抽象类并重写其抽象属性和抽象思路方法

  3、核心控制部分:在容器内铺满隐藏“块”上/下/左/右/控制形状变形和移动通过控制容器内“块”颜色来响应变化当形状下步移动或变形位置处已经有颜色时则禁止移动或变形当形状下步移动或变形位置在底边有颜色或处于容器底部则判断消行并生成新形状

  关键代码

  1、形状抽象类

  PieceBase.cs

using ;
using .Net;
using .Windows;
using .Windows.Controls;
using .Windows.Documents;
using .Windows.Ink;
using .Windows.Input;
using .Windows.Media;
using .Windows.Media.Animation;
using .Windows.Shapes;
YYTetris.Piece
{
  public abstract PieceBase
  {
    public PieceBase
    {
      InitPiece;
    }
    // 形状矩阵
    public [,] Matrix { get; ; }
    // 形状索引
    private _index = 0;
    // 形状最大索引
    public MaxIndex { get; ; }
    /**//// <summary>
    /// 化形状需要设置 Matrix 和 MaxIndex
    /// </summary>
    public abstract void InitPiece;
    /**//// <summary>
    /// 变形
    /// </summary>
    /// <s>变形后矩阵</s>
    public abstract [,] GetRotate;
    /**//// <summary>
    /// 形状颜色
    /// </summary>
    public abstract Color Color { get; }
    /**//// <summary>
    /// 获取下个形状索引如果超过最大索引则返回最初索引
    /// </summary>
    /// <s></s>
    public GetNextIndex
    {
       nextIndex = _index >= MaxIndex ? 0 : _index + 1;
       nextIndex;
    }
    /**//// <summary>
    /// 变形设置 Matrix 为变形后矩阵
    /// </summary>
    public void Rotate
    {
      Matrix = GetRotate;
      _index = GetNextIndex;
    }
  }
}


  2、继承PieceBase类以“L”为例每种形状均为个4×4矩阵1代表有“块”0代表空

  L.cs

using ;
using .Net;
using .Windows;
using .Windows.Controls;
using .Windows.Documents;
using .Windows.Ink;
using .Windows.Input;
using .Windows.Media;
using .Windows.Media.Animation;
using .Windows.Shapes;
YYTetris.Piece
{
  public L : PieceBase
  {
    public override void InitPiece
    {
      Matrix = [,]
      {
        {0,1,0,0},
        {0,1,0,0},
        {0,1,1,0},
        {0,0,0,0}
      };
      MaxIndex = 3;
    }
    public override [,] GetRotate
    {
      switch (GetNextIndex)
      {
         0:
           [,]
          {
            {0,1,0,0},
            {0,1,0,0},
            {0,1,1,0},
            {0,0,0,0}
          };
         1:
           [,]
          {
            {0,0,0,0},
            {1,1,1,0},
            {1,0,0,0},
            {0,0,0,0}
          };
         2:
           [,]
          {
            {1,1,0,0},
            {0,1,0,0},
            {0,1,0,0},
            {0,0,0,0}
          };
         3:
           [,]
          {
            {0,0,1,0},
            {1,1,1,0},
            {0,0,0,0},
            {0,0,0,0}
          };
        default:
           Matrix;
      }
    }
    public override Color Color
    {
      get { Helper.GetColor("#339933"); }
    }
  }
}


  3、核心控制类

  UIControl.cs
