python - Connect 4 error in logic -
am trying implement connect4 game in python.
for game logic start checking each point in possible directions if there 4 dots in row. logic checks until 3 dots in row. can please explain doing wrong?
i think doing wrong in recursion.
the code have developed until follows:
#function ckeck if game on def checkwin(row,col): r = row c = col #print r,c return checkwinfromcell(r,c) #function ckeck if game on current cell def checkwinfromcell(row, col): directions = [[0,1], [1,0], [1,1], [1,-1], [0,-1], [-1,0], [-1,-1], [-1,1]] d in directions: canvas.data.temp = [(row,col)] n=1 finalcheck(row,col,d,n) #print canvas.data.temp if (len(canvas.data.temp) == 4): return true #function ckeck if game on current cell in #all possible directions def finalcheck(row, col, direction,n): drow, dcol = direction[0], direction[1] ddrow = row+drow #next row check ddcol = col+dcol #next col check #boundary checks if row < 0 or row>=canvas.data.rows or col < 0 or col >=canvas.data.cols: return false #boundary checks if ddrow < 0 or ddrow>=canvas.data.rows or ddcol < 0 or ddcol >=canvas.data.cols: return false #if same color add list #print canvas.data.board[row][col] #print canvas.data.board[ddrow][ddcol] if(canvas.data.board[row][col] == canvas.data.board[ddrow][ddcol]): canvas.data.temp.append((ddrow,ddcol)) else: return false #call 3 more times recursively check if 4 connected while(n<3): n += 1 #print str(n)+" "+str(ddrow)+" "+str(ddcol) #print direction finalcheck(ddrow,ddcol,direction,n) ps : delete checkwin function nothing.
pps : tried asking same question, think not clear in question. think have tried in better way time.
while(n<3): n += 1 #print str(n)+" "+str(ddrow)+" "+str(ddcol) #print direction finalcheck(ddrow,ddcol,direction,n) you want n <= 3 or n < 4
