gomoku is a Java library typically used in Blockchain, Unity applications. gomoku has no bugs, it has no vulnerabilities and it has high support. However gomoku build file is not available. You can download it from GitHub.

gomoku playing agent using minimax & alpha-beta pruning. ##evaluation function the evaluation function counts chains of m-1, m-2, and m-3 length on the board and weights each count, m-1 being the most valuable. generally, consecutive pieces for a player is a good measure of how good the board because then the player can continue the chains to win. the nearwin methods are used to find these chains. nearwin(1) looks for chains of m-1 length and appends empty spaces on either end, since a chain of the same piece is only useful if the player is able to continue the chain. nearwin(1) for player x looks for [. x x x x] or [x x x x .] on the board. near the start of the game there are simply too many empty spaces to look at, so my agent only looks at moves adjacent to pieces it has already placed to save time. i use string manipulation to speed up runtime instead of traversing through the char[][]. when checking for win or near win states, i convert the row or column i'm looking at into a string and use methods (contains and indexof). for diagonals, i have a function that travels the board from the just placed piece in a top left to bottom

            Function to find winning line with NxN board and M pieces in a row in Python 3
            Asked 2019-Sep-11 at 14:34

            I am trying to create a function that finds if a move is winning on an NxN board where the winning condition is M pieces in a row in Python 3.

            I am pretty new to programming and in my specific case I am creating a Gomoku game (15x15 board with 5 pieces in a row to win). To get it working I created 6 for loops to check vertical, horizontal and 4 diagonals. See the code below for examples on the 2 options for left to right digonals. This takes way too long though when I need to loop through it many times (8) for computer to find if I can win or if it has a winning move.

            Instead of looping from 0 to 14, just loop from 0 to (board_size - winning_length).

            Here's an example for a 1-dimensional board:

            How to enable turn taking within game of Gomoku javafx
            Asked 2019-Sep-04 at 07:06

            I am having difficulty in enablng turn taking within my program.

            A tile on the board gets clicked and those coordinates are passed to playMakeMove() which makes the move in the board matrix and sets text to represent a move visually.

            Although when 2 players are involved (player, RandomAI), after using a loop to alternate turns, the method doesnt work. The RandomAI just makes all its moves in succession with player only making one move in the exact same spot (not waiting for mouse to be clicked).

            Im thinking the problem can be sloved via waiting for a tile to be clicked(to run method playerMakeMove) and then letting RandomAI take a turn. Not sure how to implement this.

            Below are two classes BoardGUI and Game there is also another class (not included) called Board.

            You have 2 main options for implementing a game loop. Rather than writing their equivalent in Java I'll just provide pseudocode and you can ask if you have trouble converting to Java.

            The first option is to trigger all activity from the user taking an action. So, for example, the 'event' may be a drag-and-drop, option click etc. depending on the game:

            Detecting diagonal in a row win - tic-tac-toe, gomoku
            Asked 2019-Aug-23 at 00:50

            Within a game on Gomoku a player has to get 5 in a row to win. Detecting diagonal win is a problem.

            I have tried the code below which searches a 2d matrix from top right until it finds a player token we are looking for e.g. 1, it then proceeds to search from that point diagonally to find a winning row. This works fine providing the first '1' the algorithm comes across is a part of the winning line. If it is not, and just a random piece, the algorithm returns false as it does not continue searching.

            How would Itake the last played move of the game and only search the diagonals relating to that move? Or possibly edit provided code to search the whole board.



            Answered 2019-Aug-22 at 20:44

            You are correct: searching the board for the first counter is invalid; searching the entire board is a waste of time. Start at the most recent move. Let's call that position (r, c); the player's token is still player. Check in each of the eight functional directions to see how long is the string of player. For instance, you check the NW-SE diagonal like this:

            How to interact with an exe file with python
            Asked 2019-Jul-03 at 20:02

            I have an exe file which accepts input from the keyboard, and returns a response based on the input text. When trying to read the output returned by the exe the python script freezes.

            I'm running Windows 7 and python3.7. I've tried the answer at continuously interacting with .exe file using python.

            Call p.stdout.readline() instead of p.stdout.read(). That will give you one line at a time, instead of waiting for the process to close its stdout pipe. For more information, read the documentation.

            Here's a more detailed example. Imagine this script is a replacement for your exe file:

            gridpane.getchildren().add() called from outside the controller class blocks the program
            Asked 2019-May-20 at 05:32

            I'm making a traditional Japanese board game (which is similar to Go). What I wanna do is to put an image in a square of GridPane(15*15) by calling method in the controller class from outside the class. However, the controller program blocks when carrying out "gomokuBoard.getChildren().add(imageview);" in opponent_put_stone() method. What should I do in order to put a control object from outside the controller program?

            Following is what I have already done. I commented out the line of code and carried out the program. It resulted in success except that opponents' stones didn't appear in the GUI screen.

            Here is the part of controller class. The line I mention is the last line of "opponent_put_stone" method.

            Can someone help me with my win scenario in my Gomoku program?
            Asked 2019-Feb-20 at 19:58

            I have written a program for an assignment where we had to write a simple Gomoku program. I thought I had it all, but when I compile and run, it sets off the win scenario even if I only have 4 of a kind and even if they're not next to each other. (It should only set off a win if there are five in a row of one kind...X's or O's). I feel like I should be resetting my counter back to 0 before each turn, but I'm not sure where I should be doing that. Any tips would be appreciated!



            Answered 2019-Feb-20 at 18:59

            You have problems in all three of the function that check win conditions: isHorizontalWin, isVerticalWin, and isDiagonalWin. All three increment the variable count, but this variable is never set back to zero. Additionally, the check to see if count == 5 should be made inside the loop. Here is an example on how to fix isHorizontalWin:

            Julia + GTK - global variable change in callback
            Asked 2019-Jan-16 at 16:07

            I am trying to learn Julia Language, and my current project is a "5 in a row" program. I started making an interface with Julia wrapper on Gtk for this game, but stumbled upon an interesting problem. Code is below.

            The problem is: after callback function work cur_step variable is not changing, and labels of buttons are not changing too. However, if I delete the if-condition in the callback function, buttons will all get labels "x" after pressing as it is supposed to be right now.

            I'm writing my code with Julia 1.0 in Jupyter Notebook.

            I've tried to set up cur_step variable as global, since thought that it was a scope problem, but it didn't work out.



            Answered 2019-Jan-16 at 16:07

            You need to label cur_step as global inside your function (as well as outside, for good code signposting).

            A function can use a variable from its parent scope without problems, as long as there's no assignment anywhere within the function's scope. If there is an assignment somewhere (even if it's in an if block), then the function is interpreted as local; this is true even prior to the point where its assignment occurs.

            In order to treat a variable that gets assigned at some point inside the function properly as a global one, you need to explicitly point this out inside the function by using global cur_step.

            i am new to python. i am making a game similar to tic-tac-toe, but on a larger scale. i am able to see the grid before user input, but after the user inputs where they want their piece to go the updated grid does not show. the output will just say none. im thinking my problem is in how im displaying the board, but i am unsure.Please help

            Ok there were a few errors in your code.

            1.) In the valid_location function you were checking if the piece was equal to 0 even though you assigned it as "O"

            2.) In the print_board function you were making a new board everytime.

            3.) In the drop_point function you were only assigning the value to board inside the function

            The rules of this game is that 5 items should match in a row, or in a column, or in a diagonal line. Just compare each row, column, and diagonal line to see if 5 items match, and return true. Otherwise the function should return false.

            You should do all the drawings in OnPaint. Don't draw in other functions such as OnLButtonDown. Instead, get the necessary information from OnLButtonDown and call Invalidate, this will repaint the window.

            Here is an example. For simplicity, I created a structure info and a 2-dimensional array data. data stores all the information for each cell, that is the rectangle and color. You have to initialize data once, and paint based on the information in data
