俄罗斯方块是一个很经典的游戏，做一个UWP俄罗斯方块没有什么用，我想说的是移植，把经典游戏移植到UWP。
我的所有博客都是抄别人的，这个才是我自己写的。后台很多代码还是抄别人的，我想说的是我们之前有很多游戏，很多软件使用C或者C++之类的来写，或者C#，其实我们可以把之前的算法拿出来，转换为UWP的C#，这时大家会说，界面。对，界面我们没法直接移植，但是用XAML做一个界面很快的，那么现在的问题就是，我们如何使用之前的算法来用现在的界面。
简单的一个，我们可以使用绑定。
MVVM的知识，我觉得看到一篇文章，忘了出处，希望知道的小伙伴提醒。他说，MVVM的ViewModel作用是界面的抽象。我们不用理界面，因为界面总是改，所以我们需要一个抽象的界面，就是我们做的ViewModel，那么model做的就是算法，数据。Model不知道界面怎样，他需要知道数据。ViewModel不知道界面怎样，他知道界面需要什么。
MVVM的知识我说的不算对，也不算错，但从这个看也是可以。
为什么要分开view？
其实可以看下面的：
假设我们需要做一个软件，这个软件是举报恶意转载的功能，他能够在网上搜，找到那些恶意转载的网站。
先吐槽下中国学网那些垃圾网站，全部东西都是转载的。吐槽下百度，搜索到的转载的都是前，找不到我的博客。
还是360好，能找到
我们软件开始界面
发现我们需要改
接着发现还是需要改
如果我们和界面有联系，一改界面就需要改，那么这样我们开发将会很慢。
如果我们能使用抽象，那么界面怎么改，我们修改的也就界面。

我们需要做一个游戏，我们有了之前的算法，我拿到了一位大神：http://www.cnblogs.com/china_x01/p/5253556.html
看不懂他写的，问了一位大神，他帮我改了UWP，最后我也看不懂，他写的没有注释。
做一个俄罗斯方块算法简单，我们放在后面，现在先和大家说界面。
后面说的有些小白。
我们程序：
我们在界面
放一个Canvas
里面就是游戏
因为我们需要游戏按键，所以我们需要一个TextBox
<Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
<TextBox Margin="10,10,10,10" Width="1" Height="1" KeyDown="keydown"></TextBox>
<Canvas x:Name="canvas" Margin="10,10,10,10">
</Canvas>
</Grid>每个方块
Rectangle[,] _rectangle
我们需要设计高度宽度 size = 10;，其实这里可以根据你自己需要，每个方块的size可以设置大，可以看到上面的图，我的方块是有些小。
现在就是我们重要的绑定，我们有200个Rectangle，如果每个在xaml，写我觉得我没有这么时间，也容易错
所以我们在
for (int i = 0; i < view.row; i++)
{
for (int j = 0; j < view.col; j++)
{
_rectangle[i, j] = new Rectangle()
{
Width = size,
Height = size,
Fill = new SolidColorBrush(Colors.Gray),
Stroke = new SolidColorBrush(Colors.LightCoral),
AllowDrop = false,
CanDrag = false,
Margin = new Thickness(j * size, i * size, 0, 0)
};
canvas.Children.Add(_rectangle[i, j]);
}
}后台写了200个方块，就几句。我们给宽度高度、显示的颜色。显示颜色是没有方块显示的颜色，这里说的没有方块是说没有俄罗斯方块。
然后我们给每个方块边框，Stroke，他们的位置。
这样我们的屏幕就有了200个方块，但是放进去我们会发现和我们上面的图不同，因为宽度和高度不同
canvas.Width = size * view.col;
canvas.Height = size * view.row;这样就好了。
界面大概就需要做的就这样，算法很简单，放在最后。
我们有的model，有俄罗斯方块的初始方块、移动、变形、向下
他把所有的数据保存在一个数组grid_observable，类型grid里面有个rectangle，如果为0表示这个地方没有方块，如果为1表示有方块。
类型grid
我们界面根据rectangle显示，如果有，那么显示灰色，没有显示白色。
因为我们view是不知道后台，所以这个显示需要viewModel把后台的rectangle变为颜色。
我们ViewModel把颜色放ObservableCollection<solid> solid_collection
需要把rectangle变为颜色
foreach (grid temp in _model.grid_observable)
{
if (temp.rectangle == 0)
{
solid_collection[temp.row * col + temp.col].solids = new SolidColorBrush(Colors.Gray);
}
else
{
solid_collection[temp.row * col + temp.col].solids = new SolidColorBrush(Colors.White);
}
}
为了让solid一修改就可以告诉view
public class solid : notify_property
{
public solid(SolidColorBrush solid)
{
_solid = solid;
}
public SolidColorBrush solids
{
set
{
_solid = value;
OnPropertyChanged();
}
get
{
return _solid;
}
}
private SolidColorBrush _solid;
}因为每次写INotifyPropertyChanged要写很多，我们需要通知有很多 ，所以写notify_property
ViewModel能把后台的rectangle变颜色，那么我们view把颜色显示
我们刚才new 了200个Rectangle我们把他的颜色绑定ViewModel
如果使用xaml，我觉得我没法
那么我们在代码
_rectangle[i, j] = new Rectangle()
{
Width = size,
Height = size,
Fill = new SolidColorBrush(Colors.Gray),
Stroke = new SolidColorBrush(Colors.LightCoral),
AllowDrop = false,
CanDrag = false,
Margin = new Thickness(j * size, i * size, 0, 0)
};
Binding bind = new Binding()
{
Path = new PropertyPath("solid_collection[" + (i * view.col + j) + "].solids"),
Mode = BindingMode.OneWay
};
_rectangle[i, j].DataContext = view;
_rectangle[i, j].SetBinding(Shape.FillProperty, bind);绑定可以Binding bind = new Binding()
里面写路径，可以数组中Path = new PropertyPath("solid_collection[" + (i * view.col + j) + "].solids"),
其实Path写在new Binding(string Path)
我们可以设置Source = view
Binding bind = new Binding()
{
Path = new PropertyPath("solid_collection[" + (i * view.col + j) + "].solids"),
Mode = BindingMode.OneWay,
Source = view
};也可以_rectangle[i, j].DataContext = view;
写完我们需要
_rectangle[i, j].SetBinding(Shape.FillProperty, bind);如果我们后台是可以的，那么我们就能看到
我想说的不是写俄罗斯，而是把之前的软件移植，我们可以把二维表，bool，表示为颜色，把颜色显示，我们有很多游戏都是可以这样，那么移植UWP简单，需要使用绑定，一个转换。
大神：可以直接绑定转换。
其实我是不喜欢直接绑定就转换，因为这样类很多，我们需要文件夹
Convert里面是转换类
我想说的不是做一个俄罗斯方块，而是把之前数据保存二进制矩阵的游戏移植到UWP思路。很简单不用多修改就可以使用，界面我们可以自己来写，只要绑定写了，那么就可以使用。
写到这，后面都是小白
我们先打开vs神器，之前下载vs安装，需要sdk，这个在安装自己弄。
新建项目，我叫tetris
新建一个类叫viewModel，一个model
再新建一个类notify_property，接口INotifyPropertyChanged
/// <summary>
/// 提供继承通知UI改变值
/// </summary>
public class notify_property : INotifyPropertyChanged
{
public event PropertyChangedEventHandler PropertyChanged;
public void UpdateProper<T>(ref T properValue , T newValue , [System.Runtime.CompilerServices.CallerMemberName] string properName = "")
{
if (object.Equals(properValue , newValue))
return;
properValue = newValue;
OnPropertyChanged(properName);
}
public void OnPropertyChanged([System.Runtime.CompilerServices.CallerMemberName] string name="")
{
PropertyChangedEventHandler handler = PropertyChanged;
handler?.Invoke(this , new PropertyChangedEventArgs(name));
}
}这个类是我们每次需要INotifyPropertyChanged都需要写PropertyChanged，觉得还是放成类，让需要的继承
俄罗斯方块有
我们把算法写model
方块有
我们需要做一个来保存
public enum block
{
straight,
square,
t,
bent
}那么我们需要一个来放我们的方块
public class grid : notify_property
{
public grid()
{
_rectangle = 1;
}
public grid(int col, int row)
{
_col = col;
_row = row;
_rectangle = 0;
}
public grid clone()
{
return new grid(col, row);
}
public int row
{
set
{
_row = value;
OnPropertyChanged();
}
get
{
return _row;
}
}
public int col
{
set
{
_col = value;
OnPropertyChanged();
}
get
{
return _col;
}
}
public int rectangle
{
set
{
_rectangle = value;
}
get
{
return _rectangle;
}
}
private int _col;
private int _rectangle;
private int _row;
}行列，是否有方块
我们发现这个只能放一个方块，所以我们写
放着grid[] _grid;
新建方块：
square(block block, int center)
我们需要方块是什么，中心
我们先做直线
public square(block block, int center)
{
_block = block;
int n = 4;
_grid = new grid[n];
for (int i = 0; i < n; i++)
{
_grid[i] = new grid();
switch (block)
{
case block.straight:
_grid[i].col = center;
_grid[i].row = -i;
break;
default:
throw new ArgumentOutOfRangeException(nameof(block), block, null);
}
}
}我们来做t
case block.t:
_grid[0].col = center;
_grid[0].row = 0;
if (i > 0)
{
_grid[i].col = center + i - 3;
_grid[i].row = -1;
}square
case block.square:
if (i <= 1)
{
_grid[i].col = center + i;
_grid[i].row = 0;
}
else
{
_grid[i].col = center + i - 2;
_grid[i].row = -1;
}bent
case block.bent:
if (i <= 1)
{
_grid[i].col = center + i;
_grid[i].row = 0;
}
else
{
_grid[i].col = center + i - 3;
_grid[i].row = -1;
}
public square(block block, int center)
{
_block = block;
int n = 4;
_grid = new grid[n];
for (int i = 0; i < n; i++)
{
_grid[i] = new grid();
switch (block)
{
case block.straight:
_grid[i].col = center;
_grid[i].row = -i;
break;
case block.t:
_grid[0].col = center;
_grid[0].row = 0;
if (i > 0)
{
_grid[i].col = center + i - 3;
_grid[i].row = -1;
}
break;
case block.square:
if (i <= 1)
{
_grid[i].col = center + i;
_grid[i].row = 0;
}
else
{
_grid[i].col = center + i - 2;
_grid[i].row = -1;
}
break;
case block.bent:
if (i <= 1)
{
_grid[i].col = center + i;
_grid[i].row = 0;
}
else
{
_grid[i].col = center + i - 3;
_grid[i].row = -1;
}
break;
default:
throw new ArgumentOutOfRangeException(nameof(block), block, null);
}
}
}这样看起来代码很多，这样不好，我们需要把每个放在一个函数
public square(block block, int center)
{
_block = block;
int n = 4;
_grid = new grid[n];
for (int i = 0; i < n; i++)
{
_grid[i] = new grid();
switch (block)
{
case block.straight:
block_straight(center, i);
break;
case block.t:
block_t(center, i);
break;
case block.square:
block_square(center, i);
break;
case block.bent:
block_bent(center, i);
break;
default:
throw new ArgumentOutOfRangeException(nameof(block), block, null);
}
}
}
private void block_straight(int center, int i)
{
_grid[i].col = center;
_grid[i].row = -i;
}
private void block_t(int center, int i)
{
_grid[0].col = center;
_grid[0].row = 0;
if (i > 0)
{
_grid[i].col = center + i - 3;
_grid[i].row = -1;
}
}
private void block_bent(int center, int i)
{
if (i <= 1)
{
_grid[i].col = center + i;
_grid[i].row = 0;
}
else
{
_grid[i].col = center + i - 3;
_grid[i].row = -1;
}
}我们model还没写东西
我们先做新建方块
我们需要最大值
public int row
{
set
{
_row = value;
}
get
{
return _row;
}
}
public int col
{
set
{
_col = value;
}
get
{
return _col;
}
}
private int _col = 10;
private int _row = 20;当前方块
public square _square
{
set;
get;
}新建方块
private void new_block()
{
block _block = (block)ran.Next(4);
int center = _col / 2;
_square = new square(_block, center);
}我们现在没有想着去什么，我们需要显示
每次下降
public void down()
{
if (_square == null)
{
new_block();
}
}我们在ViewModel
public viewModel()
{
solid_collection = new ObservableCollection<solid>();
for (int i = 0; i < col * row; i++)
{
solid_collection.Add(new solid(new SolidColorBrush(Colors.Gray)));
}
DispatcherTimer time = new DispatcherTimer
{
Interval = TimeSpan.FromSeconds(0.5)
};
time.Tick += tick;
time.Start();
}
public int col
{
set
{
value = 0;
}
get
{
return _model.col;
}
}
public int row
{
set
{
value = 0;
}
get
{
return _model.row;
}
}
public ObservableCollection<solid> solid_collection
{
set;
get;
}
private void tick(object sender, object e)
{
DispatcherTimer time = sender as DispatcherTimer;
time?.Stop();
down();
time?.Start();
}
public void down()
{
_model.down();
}我们需要DispatcherTimer，给他时间Interval = TimeSpan.FromSeconds(0.5)就向下
如果model
if (_square == null)
{
new_block();
}我们现在新建出来，还没有显示
我们需要把_square显示
viewModel
public void down()
{
_model.down();
foreach (grid temp in _model._square._grid.Where(temp => temp.col >= 0 && temp.row >= 0))
{
solid_collection[temp.row * col + temp.col].solids = new SolidColorBrush(Colors.White);
}
}我们现在除了界面，都做好了。
打开MainPage
<Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
<TextBox Margin="10,10,10,10" Width="1" Height="1" KeyDown="keydown"></TextBox>
<Canvas x:Name="canvas" Margin="10,10,10,10">
</Canvas>
</Grid>TextBox 我们需要按键
private viewModel view;
public MainPage()
{
InitializeComponent();
rectangle();
}rectangle绑定我们的界面
绑定在上面有写了
private void rectangle()
{
view = new viewModel();
Rectangle[,] _rectangle = new Rectangle[view.row, view.col];
double height = 600;
double size = height / view.row;
if (size < 10)
{
size = 10;
}
canvas.Width = size * view.col;
canvas.Height = size * view.row;
canvas.Background = new SolidColorBrush(Colors.BurlyWood);
for (int i = 0; i < view.row; i++)
{
for (int j = 0; j < view.col; j++)
{
_rectangle[i, j] = new Rectangle()
{
Width = size,
Height = size,
Fill = new SolidColorBrush(Colors.Gray),
Stroke = new SolidColorBrush(Colors.LightCoral),
AllowDrop = false,
CanDrag = false,
Margin = new Thickness(j * size, i * size, 0, 0)
};
Binding bind = new Binding()
{
Path = new PropertyPath("solid_collection[" + (i * view.col + j) + "].solids"),
Mode = BindingMode.OneWay
};
_rectangle[i, j].DataContext = view;
_rectangle[i, j].SetBinding(Shape.FillProperty, bind);
canvas.Children.Add(_rectangle[i, j]);
}
}
}我们可以开始运行，就可以看到，只下来一块
我们要让整个方块向下
public void down()
{
if (_square == null)
{
new_block();
}
foreach (grid temp in _square._grid)
{
temp.row++;
}
}每个都向下
我们会发现我们的方块下到最下还是没有停下来
我们需要判断方块是不是到最下
判断方块是不是要到的位置不可以，这句话是说判断是不是在grid里，位置超过最大可以的位置，或者小于0，位置是不是有方块。
private bool rectangle(square _square)
{
bool _rectangle = true;
foreach (grid temp in _square._grid)
{
if (temp.col >= 0 && temp.row >= 0)
{
int n = (temp.row ) * col + temp.col;
if (_grid_observable.Count > n && _grid_observable[n].rectangle != 0)
{
_rectangle = false;
}
}
else if (temp.col < 0)
{
return false;
}
if (temp.row >= _row || temp.col >= _col)
{
return false;
}
}
return _rectangle;
}我们先复制方块，然后让方块向下，判断是个方块是不是可以在他的位置，如果可以，复制回去。
public void down()
{
if (_square == null)
{
new_block();
}
square temp = _square.clone();
foreach (grid t in temp._grid)
{
t.row++;
}
if (rectangle(temp))
{
_square = temp;
}
}复制
public square clone()
{
square temp = new square(_block, 0);
for (int i = 0; i < _grid.Length; i++)
{
temp._grid[i] = _grid[i].clone();
}
temp.rotate_count = rotate_count;
return temp;
}运行我们可以看到方块能向下，在最下停下，但是不会出新方块，我们需要判断向下，如果没有可以位置，那么新方块
public void down()
{
if (_square == null)
{
new_block();
}
square temp = _square.clone();
foreach (grid t in temp._grid)
{
t.row++;
}
if (!rectangle(temp))//修改
{
draw(); //画出来
new_block();
}
else
{
_square = temp; //为什么不clone
}
}上面代码留有一个问题，就是最后的把可以的位置复制回去怎么不需要写复制，当然这个简单。
我们现在还需要看画出来
我们需要把方块画在grid，那些我们无法移动的方块需要画在grid
private void draw()
{
int n = 0;
foreach (grid temp in _square._grid)
{
if (temp.col >= 0 && temp.row >= 0)
{
n = temp.row * col + temp.col;
if (_grid_observable.Count > n)
{
_grid_observable[n].rectangle = 1;
}
}
}
clean();
}画完我们判断是不是可以删掉，判断一行是不是有方块，有就删掉
private void clean()
{
bool _rectangle = true;
int n = 1;
foreach (grid temp in _grid_observable)
{
if (temp.col < _col - 1)
{
_rectangle = _rectangle && temp.rectangle != 0;
}
else if (temp.col == _col - 1)
{
_rectangle = _rectangle && temp.rectangle != 0;
if (_rectangle)
{
for (int i = n*_col - 1; i > _col; i--)
{
_grid_observable[i].rectangle = _grid_observable[i - _col].rectangle;
}
n--;
}
n++;
_rectangle = true;
}
}
}现在我们需要写移动
左移col–，判断是否可以存在，可以，复制回去
public void move(bool left)
{
square temp = _square.clone();
foreach (grid t in temp._grid)
{
if (left)
{
t.col--;
}
else
{
t.col++;
}
}
if (rectangle(temp))
{
_square = temp;
}
}我们基本做好了俄罗斯方块算法
我们去mainpage写
private void keydown(object sender, Windows.UI.Xaml.Input.KeyRoutedEventArgs e)
{
if (e.Key == VirtualKey.Up)
{
view.translate();
}
else if (e.Key == VirtualKey.Left)
{
view.move(true);
}
else if(e.Key==VirtualKey.Right)
{
view.move(false);
}
else if (e.Key == VirtualKey.Down)
{
view.down();
}
}viewmode只是使用model
public void move(bool left)
{
_model.move(left);
}运行，我们可以开始玩了，然后你会发现好像我们还少个没有写
我把全部代码放下面，我希望等到你不知道怎么写才去，我的变量命名其实有问题，如果可以去改下，因为按shift然后大写实在不会，所以都是_。如果觉得_需要两个键，就让我卖关子，其实我只需要使用-，怎么做我会在之后告诉大家
