pac-man | basic pac-man game written in JavaScript | Game Engine library

I am trying to get this pacman animation to cycle through an array of images and reverse direction when it hits the edge of the page.

I tried debugging in Chrome and it gave me the following error

"cannot read properties of null (reading width)"

Im building a pacman game and i put a switch statement and put interval so that the user has to press right arrow once and pacman will keep moving right the problem is that if i tab twice it move twice as fast and i tab right then left it'll move right left right left.....

i'll show the first code where there was no problem this code is without interval

JS code without interval:

I decided to make a Pac-Man game and after I did it and everything was working somewhat fine on local document I pushed my website on Github pages and decrease in fps was enormous. It turned out page was making recalculation for hundreds elements which caused 20ms+ delay.

Here's a small part of the code that still has performance difference between local and github-pages hosted website.

I'm trying to make an online game where I want to simulate a world that is connected in all directions, just like "PAC-MAN" does. When the player crosses the boundaries of the map he would be in the other side of the grid.

So far so good, I managed to build a server that holds a 10x10 matrix, (I attach some images as a reference), and using some modular-arithmetics it calculates and sends to the client the corresponding tiles of the map given the player's position.

So assuming "view_distance = 2" for example, the server sends the corresponding tiles based on the player's position:

Player position (4,4)

Player position (9,5)

Player position (0,0)

I think I made my point, now lets face my problem.

When the client gets the list of tiles to render from the server, it needs to calculate the distance to the player (unit-vector) for each tile so it can instance it in the right place. Every instanced tile has a script that recalculates the distance to the player every time he moves so it destroys itself when it is farther than the "view_distance".

So for example, if I the client is in the position (9,5) the unit-vector of the tile (7,7) would be (-2,2)

The client has the following information:

• The tile where he's standing: Globals.PlayerInfo.PlayerPosition
• The lenght of the map: Globals.MAP_LENGHT (in this case it's 10)
• The view distance: Globals.DATA_DISTANCE (in this case it's 2)

How do i calculate the unit-vector? I made the following function but it doesn't seem to work. Am I missing something?

I am writing a Pac-Man game, and so far I've got the movement and animation down but for some reason, Pac-Man just keeps freezing every 2 seconds or so. It's very slight and quick, but noticeable enough. Maybe this has something to do with my browser (Google Chrome) or the way I'm setting up the setTimer functions? I'm also aware of the canvas feature in JavaScript, I just wanted to make this game without it for a challenge.

Hey I am currently building a simple pacman in javascript as a learning project. I am able to render a basic board, pacman, pellets and big pellets with basic canvas drawings (arc etc) . The game is responsive to key codes moving pacman around but Imstruggling when I want to test for collision and access x and y values of canvas drawings. My board is drawn in for loop that iterates through a layout/grid 2d array of numbers and draws something different depending on the number, 0 representing walls, 1 - pellets etc. I feel I may be making an error in the drawBoard for loop also.. I have started to go back and forth between using a function to draw walls and then trying to access its X and Y positions:

I have a problem about implementing recommendation system by using Euclidean Distance.

What I want to do is to list some close games with respect to search criteria by game title and genre.

Here is my project link : Link

After calling function, it throws an error shown below. How can I fix it?

Here is the error

I am trying to make Pac-man Game using turtle. When I run my code it shows small dots. While moving turtle press w to go up-ward and you can find the small dot at bottom of player.

This is a code for Pac-Man. I already have a moving Pac-man and the collision w/ the ghosts, but I don't know how to make them randomly move on the map. I don't need them to chase the Pac-Man, just to slide randomly through the map and change direction when they hit on the wall. I also wanted to know how could I make Pac-Man die when he collides w/ a ghost.
