connect-four | Connect Four webapp using WebSockets for multiplayer support | Websocket library

I am currently building a connect-four game based on react.js. It has the following semantic: The game has 3 state variables: grid(play field), pNext(boolean if human is next), gameState(is game won, lost, or running?)

1. Human will click on column and onclick event handleClick(i) is triggered with the column index. It checks the gameState and will call the makeMove(i) function to make the players move. Now is the question, I cant wait for the makeMove function because it even returns when the state variables are not changed.

makeMove will place the stone in the respective column.

handleClick function:

makeMove function:

1. Now I can't wait for the useEffect() of one variable because I need all three game variables to be changed. (If the bool changed but the grid is not updated -> error etc.)

EDIT: useEffect() hook picture and the vars:

I am making a Connect-Four game. every column (component) recieves the current player color as a prop from the parent component. i have a callback function in every column that changes the current player state every time a column is being clicked, but for some reason the columns won't accept the new parent state as an updated prop.

Essentially im trying to create a connect four Ai and i came across an article which uses bit boards to optimize making moves and checking for wins. Essentially i took a few methods from a git hub readme which are supposed to make a move and undo a move on your bit board unfortunately it appears that the methods are not working properly because it's placing ones at the end of the bit string instead of spacing them by 7. I assume this is probably some java thing that is preventing these from working correctly and i have posted a sample program below which i think demonstrates the problem accurately. For example if i set a long variable so that it has a row of four ones on the 5th row and display it. It displays correctly without the beginning zeros but on the other hand if i add three tokens to the first column. And then three tokens to the third column. It displays as 111, and 111. When it should be

I had a working example of a project a year back, which is not working anymore.

It's basically related to change in the behavior of nginx.ingress.kubernetes.io/rewrite-target property mentioned here - https://github.com/kubernetes/ingress-nginx/tree/master/docs/examples/rewrite

I have 3 application and I want to route based on conditions.

• /* to frontend-cluster-ip-service
• /api/battleship/* to battleship-cluster-ip-service
• /api/connect4/* to connect-four-cluster-ip-service

The working example that was working an year back was

I'm trying to create Connect-Four using tkinter. Once a disc is placed in a certain column, I want it to descend to the bottom of the column in a fluid movement.

I've tried using the move command of the Canvas class but I'm unsure if I am using it incorrectly or perhaps I am better off deleting and re-drawing the oval each iteration. Currently, the disc indeed moves but not in a fluid way. It simply draws it in the new location.

This is the disc moving function:

I am writing a connect-four game for more OO and rspec practice. As part of my program, I would like to prompt the user to choose a column that they would like to put their game piece in. Here's that method:

I'm trying to make a connect four game, but I got stuck on how I'll reduce the column height when a player chooses a cell then drop. I tried to google it and found this I can't understand, could somebody explain it

Here is the error I am getting when I go to manually deploy on heroku's website. First I was getting an error in my .json file, so I specified both the "npm", "yarn" and "node" versions I was running. Those errors appeared to clear up. Now I am this one and have searched google but cannot seem to find much on fixing it.

I have been working for a while with artificial intelligence problems and in this week i have tried to code AI to connect 4 with python. First I had problems with copying board but I figured out that in python you need to use deepcopy to avoid copying errors.

Finally I managed to create alpha-beta pruning algorithm and it works OK but then I tested my algo in depth 8 against online alpha-beta pruning algo in depth 6 and surprisingly my algorithm lost. I created evaluation function with harvard's instructors and modified alpha-beta from msavenski's code (links are in the code)

Could some who have been working with these problem longer check that my algo and evaluation function works as expected because im quite sure that there is some mistake. I know that I could use tranposition tables, deep iteration and so on to make code faster and more effective but my other goal is to keep it simply.

Here is my code:
