Tic Tac Toe获胜并获得支票-Matlab [英] Tic Tac Toe with a win and taken check - Matlab

问题描述

我正在制作井字游戏，每次尝试调试时都会遇到各种错误.我不确定问题出在哪里.主要错误是

I'm making a tic tac toe game and I'm bombarded with various errors everytime I try to debug. I'm not sure where the problem is. The main error is either

  Index exceeds matrix dimensions

或

  Subscript indices must either be real positive integers or logicals

我的"checktaken"功能的第8行中的

. 以下是我的代码，其中tttGame是主要功能，boardplot进行绘制，checkwintest/check进行查看是否获得位置或是否获胜.我已向许多人寻求帮助，但大多数人都不知道到底出了什么问题.您的答案的示例/代码将有所帮助.谢谢！ 主要功能:

in line 8 of my 'checktaken' function. Below is my code, where tttGame is the main function, boardplot does the plotting, and checkwintest/check taken see if a position is taken or if there is a win. I have asked many people for help and most haven't a clue whats wrong. Examples/code of your answers will help. Thanks! Main function:

function tttGame
%% 
%This function determines which players turn it is and whether there is a
%win or not
wonX = 0;
wonO = 0;
tttArray = zeros(3);
tttXArray = zeros(3);
tttOArray = zeros(3);
while wonX ~= 1 || wonO ~= 1
    %%
    %Initialize values
        pXInputRow = 0;
        pXInputCol = 0;
        pOInputRow = 0;
        pOInputCol = 0;

    %%
    %Show prompt to input values
        pXInputRow = input('Player X Enter Row: ');
        pXInputCol = input('Player X Enter Column: ');
        %Plot and prompt Player X
        boardplot(tttArray, pXInputRow, pXInputCol, pOInputRow, pOInputCol)

        %Check taken location
        checktaken(tttArray, pXInputRow, pXInputCol, pOInputRow, pOInputCol);
        %If place is taken, prompt player to input again
        if  checktaken(tttArray, pXInputRow, pXInputCol, pOInputRow, pOInputCol)  == 1
            %Show prompt to input values
            msgbox('That spot is taken')
            pXInputRow = input('Enter Row: ');
            pXInputCol = input('Enter Column: ');
        %Otherwise, continue and change taken/player position on board
        else
            tttArray(pXInputRow, pXInputCol) = 1; %Set the position as taken
            tttXArray(pXInputRow, pXInputCol) = 1; %Set the position for X

        end

    %Check if theres a win
        checkwintest(tttXArray, tttOArray)
        %Reset values
        pXInputRow = 0;
        pXInputCol = 0;
    %%
    %Show prompt to input values
        pOInputRow = input('Player O Enter Row: ');
        pOInputCol = input('Player O Enter Column: ');
        %Prompt and plot Player O
        boardplot(tttArray, pXInputRow, pXInputCol, pOInputRow, pOInputCol)

    %Check taken location
        checktaken(tttArray, pXInputRow, pXInputCol, pOInputRow, pOInputCol);
        %If place is taken, prompt player to input again
        if checktaken(tttArray, pXInputRow, pXInputCol, pOInputRow, pOInputCol) == 1
            %Show prompt to input values
            msgbox('That spot is taken')
            pOInputRow = input('Enter Row: ');
            pOInputCol = input('Enter Column: ');
        %Otherwise, continue and change taken/player position on board
        else
            tttArray(pOInputRow, pOInputCol) = 1;%Set the position as taken
            tttOArray(pOInputRow, pOInputCol) = 1;%Set the position for O;

        end

%%
    %Check win again
    checkwintest(tttXArray, tttOArray)
    %Reset values
    pOInputRow = 0;
    pOInputCol = 0;
end
end

中奖功能

function [wonX, wonO] = checkwintest(tttXArray, tttOArray, tttGame)
      %Test to see whether this format of win testing works

      %Find any nonzero value in the tttX/OArray matrix. Returns 1 if true.
      %All Columns, rows, diagonals
       if any(all(tttXArray)) || any(all(tttXArray, 2)) || any(all(diag(tttXArray)))...
              || any(all(diag(fliplr((tttXArray)))));
          wonX = 1;
       elseif any(all(tttOArray)) || any(all(tttOArray, 2)) || any(all(diag(tttOArray)))...
               || any(all(fliplr(diag(tttOArray))));
          wonO = 1;
       else
           wonX = 0;
           wonO = 0;
       end
       %Send a message if a player won
       if wonX == 1
           playerXWonMessage = 'Congratulations Player X, you win!';
           msgbox(playerXWonMessage)
           exit(tttGame);
       elseif wonO == 1
           playerOWonMessage = 'Congratulations Player O, you win!';
           msgbox(playerOWonMessage)
           exit(tttGame);
       end
      end

然后

  function  [spotTaken] = checktaken(tttArray, pXInputRow, pXInputCol, pOInputRow, pOInputCol)
  %Function used to check if spot is taken
  %Setup Error Messages
  errorMessage = 'This spot is taken, please choose another spot';
  errorMessageTitle = 'Spot Taken';
  spotTaken = 0;

  if (tttArray(pXInputRow, pXInputCol)  == 1) || (tttArray(pOInputRow, pOInputCol) == 1)
      msgbox(errorMessage, errorMessageTitle)
      spotTaken = 1;
  end

  end

和

  function boardplot(tttArray, pXInputRow, pXInputCol, pOInputRow, pOInputCol)
  %Setup the window for the game
      close all;
      clc;
      figure('Name','Tic Tac Toe');
      plot(-1. -1)
      axis([0 3 0 3])
      set(gca,'xTick',1:3)
      set(gca,'yTick',1:3)
      set(gca,'xTickLabel',[1 2 3])
      set(gca,'yTickLabel',[1 2 3])
      grid on
      hold on
      shg

      %Plot
      plot(pXInputRow - 0.5, pXInputCol - 0.5,'x', 'MarkerSize', 50)
      hold on
      plot(pOInputRow - 0.5, pOInputCol - 0.5,'o', 'MarkerSize', 50)
      hold on

  end

推荐答案

所以我解决了这个问题，并重写了大部分代码. 首先，我没有将适当的输入传递给函数checktake(和其他函数)，这显然会导致一些错误. 然后，我重新编写了用户输入语句，以仅对行/列使用2个变量，而不是4个变量，每个玩家有2个变量. Checktaken重写如下:

So I solved the problem and rewrote most of my code. First I did not pass the proper inputs to the function checktaken (and other functions) which obviously led to some errors. Then I rewrote my user input statements to use only 2 variables for rows/cols rather than 4, where there are 2 for each player. checktaken is rewritten as follows:

  function  [spotTaken] = checktaken(tttArray, x, y)
  %This function is used to check if spot is taken
  %Function takes users row/col input as indices for the taken locations
  %array, 'tttArray'. It then returns whether the spot is taken or not.

  %Setup Error Messages
  errorMessage = 'This spot is taken, please choose another spot';
  errorMessageTitle = 'Spot Taken';
  spotTaken = 0; %Initialization

  %If the location's value is 1(taken), show error message and return
  %spotTaken as 1(true).
  if tttArray(x,y) == 1
      msgbox(errorMessage, errorMessageTitle)
      pause(3)
      spotTaken = 1;
  end

  end

然后我通过输入

  function [a,b] = pickunospot
      %This nested function creates the prompt for the player and takes
      %the inputs as indices to be used later on in our arrays
      prompt = {'Row (1,2, or 3)', '(Col (1, 2, or 3)'};
      name = 'Enter your choice of row or column';

      pt=inputdlg(prompt, name);
      a = str2num(pt{2});
      b = str2num(pt{1});
      end

并这样称呼它

 [x,y] = pickunospot;

其中x和y是行/列，可以用作checktaken中的矩阵索引. 这样可以防止任何矩阵索引错误，并通过输入参数不足"来限制问题.

where x and y are the rows/cols and can be used as matrix indices in checktaken. This prevented any matrix index errors and limited the issue with 'not enough input arguments'.
