我如何...子菜单无法正常工作 [英] How do I...submenus not working right

问题描述

我在井字游戏中工作.我有一个文件菜单，如果我们选择播放器一和播放器二，它应该从我们那里接受输入；当我们选择播放器一和计算机时，它应该从我们和其他帧中获取一个输入.电脑.但是这样做并不能帮上忙.........

               }
           }

       } 

解决方案

方法中的设置值与方法返回的值不相同:
如果您有一个名为nnPlayersGame的方法，并且您编写了代码来调用它:

 如果(nnPlayersGame())
   {
   // 真实路径
   ...
   }
其他
   {
   // 错误的路径
   ...
   } 

，那么代码是遵循"True path"还是"False path"仅取决于方法的return语句中指定的值:

 公共 布尔 nnPlayersGame()
   {
   返回 numberOfPlayers >   1 ;
   } 

根据numberOfPlayers的值，代码将遵循不同的路径:

 0错误的路径
1条错误路径
2真实路径
3真实路径

因此，您需要使您的方法返回正确的值，或者检查它们设置的值，而不是再次调用它们:

 私有 无效 Button_click(对象发​​件人，EventArgs e)
       {
           按钮b =(按钮)发送器;
           如果(twoPlayersPlayGame())
          {
               如果(playerTwoToolStripMenuItem.Checked& playerTurn ==  true )
               {
                   b.Text = " ;
                   playerTurn =  false ;
                   b.Enabled =  false ;
                  computerPlayer =  true ;
               }
               其他
               {
                   b.Text = " ;
                   playerTurn =  true ;
                   b.Enabled =  false ;
               }
               clicksCount ++;
               checkWinner();
          }
           如果(computerToolStripMenuItem.Checked)
          {

               如果(！playerTurn&& computerPlayer)
               {
                   computerMove();
                   p2TextBox2.Text = " ;
               }
           }
       } 

应该可以使您更进一步.

       {
           //twoPlayersPlayGame();
           playerOneToolStripMenuItem.Checked = true;
       }

           if (withComputer())
          {

               if (!playerTurn && computerPlayer)
               {
                   computerMove();
                   p2TextBox2.Text = "Computer";
               }
           }

       }

解决方案

Setting values within a method and the value returned from the method are not the same:
if you have a method called nnPlayersGame and you write code to call it:

if (nnPlayersGame())
   {
   // True path
   ...
   }
else
   {
   // False path
   ...
   }

then whether the code follows the "True path" or the "False path" depends only on the value specified in the return statement of the method:

public bool nnPlayersGame()
   {
   return numberOfPlayers > 1;
   }

Depending on the value of numberOfPlayers the code will follow different paths:

0     False path
1     False path
2     True path
3     True path

So you need to make your methods return the correct value, or check the values that they set instead of calling them again:

private void Button_click(object sender, EventArgs e)
       {
           Button b = (Button)sender;
           if (twoPlayersPlayGame())
          {
               if (playerTwoToolStripMenuItem.Checked && playerTurn == true)
               {
                   b.Text = "X";
                   playerTurn = false;
                   b.Enabled = false;
                  computerPlayer = true;
               }
               else
               {
                   b.Text = "O";
                   playerTurn = true;
                   b.Enabled = false;
               }
               clicksCount++;
               checkWinner();
          }
           if (computerToolStripMenuItem.Checked)
          {

               if (!playerTurn && computerPlayer)
               {
                   computerMove();
                   p2TextBox2.Text = "Computer";
               }
           }
       }

Should get you a little further.
