我正在写一个井字游戏,“编码规则”的一部分是应该有一个“checkwin”功能来查看玩家是否赢了。我定义了两个变量,称为“tttXArray”和“tttOArray”,以查看一个玩家是否连续获得三个水平、垂直或对角线输入。这是以 tttXArray 为例的函数:
function [won] = checkwin
%Check to see whether the game has been won or not
% Horizontal
if (tttXArray(1,1) == tttXArray(1,2) && tttXArray(1,1) == tttXArray(1,3))
won = 1;
elseif (tttXArray(2,1) == tttXArray(2,2) && tttXArray(2,1) == tttXArray(2,3))
won = 1;
elseif (tttXArray(3,1) == tttXArray(3,2) && tttXArray(3,1) == tttXArray(3,3))
won = 1;
% Vertical
elseif (tttXArray(1,1) == tttXArray(2,1) && tttXArray(1,1) == tttXArray(3,1))
won = 1;
elseif (tttXArray(1,2) == tttXArray(2,2) && tttXArray(1,2) == tttXArray(3,2))
won = 1;
elseif (tttXArray(1,3) == tttXArray(2,3) && tttXArray(1,3) == tttXArray(3,3))
won = 1;
% Diagonal
elseif (tttXArray(1,1) == tttXArray(2,2) && tttXArray(1,1) == tttXArray(3,3))
won = 1;
elseif (tttXArray(1,3) == tttXArray(2,2) && tttXArray(1,3) == tttXArray(3,1))
won = 1;
end
end
Checkwin 是 while 循环的一部分:
while ~checkwin
playerXTurn = 1;
playerOTurn = 1;
%Let Player X go first
while playerXTurn
pickXSpot %Prompt Player
disp('Test1')
checktaken %Check taken location
%If place is taken, prompt player to input again
if checktaken == 1
pickXspot
else
tttArray(pXInputRow, pXInputCol) = 1; %Set the position as taken
tttXOArray(pXInputRow, pXInputCol) = 1; %Set the position for X(1)
plot(pXInputRow, pXInputCol, 'x')
hold on
playerXTurn = 0;
end
end
%Check if theres a win
checkwin
%Otherwise continue to Player O's turn
while playerOTurn == 1
pickOSpot %Prompt Player
checktaken
%If place is taken, prompt player to input again
if checktaken == 1
pickOspot
else
tttArray(pOInputRow, pOInputCol) = 1;%Set the position as taken
tttXOArray(pOInputRow, pOInputCol) = 0;%Set the position for O(0)
plot(pOInputRow, pOInputCol,'o')
hold on
end
end
%Check win again
checkwin
end
我得到的错误是:
Undefined function 'tttXArray' for input arguments of type 'double'.
似乎是什么问题?
