The game's graphic does not scale up or down when resizing windows

To speed up the connection. Send/receive data in binary format is a better idea than string/object.

When starting a game i can see my red dot, but as soon as i move my cursor the server says "Hit test: NaN ± 10" and the food dots begin to appear.

Any of demos not work.

It's time to talk about unit testing.
I used Jasmine for many of my previous project so I choose Jasmine.
If you got any better idea (mocha/chai or something, idk), please suggest.

You can hide enemies, if you have bigger resolution screen than them.

Using interval to respawn foods cost too much CPU usage and it makes the game laggy.
Tested with 2 clients on localhost still lage 👎

It's time to add some virus to the game.
My idea is:

• The virus will be in violet color (#9b59b6 for filling color, #9b50ba for border color)
• Virus also has it's own mass
• Virus can be feed to get more mass (become larger)
• Player will be exploded if he has bigger size than the virus (and he eat it)

More idea?

Shouldn't the code be more structured? What about adding some .editorconfig file and linting/hinting? Would you accept such PRs?

Hi, I have a problem with the configuration of Agar Clone on Cloud9 (c9.io). I installed everything, I configured IP and port (0.0.0.0), but after starting the application error pops up:

In addition, I give a private message to log data hosting, in order to help. Have you some free hosting to test it yourself to calm the game engine? Thanks in advance for any help! :)

I've tried multiple different servers, even the demo, Im pretty sure its due to my bad computer or the network usage, just thought I'd put this as a bug as I do not lag on agar.

a menu that you can choose your name can be very cool.

Should create Players and Player object.

Players should be initialized once to hold all players object. It should also have all the methods related to findPlayer, getPlayersList etc.

The Player object should have the x, y etc. And it should probably inherit the playerConfig. This object should be initialized in socket.on("welcome", function(us

Perhaps it also should be packed in webpack, so the code could be shared on the client and server side?

Thoughts?

If a player's name includes a 4, then it renders with a spike above it. See screenshot. Size varies dependant on cell mass. Not critical, just strange.

I'm taking this if approved

@REMOVEIT has done a great work at #75
So now we can do some CSS to give the menu a better look. I suggest this design:

or whatever else we want to test

Seeming randomly, after playing with 15 people, the largest person went invisible, you could clearly see him eating the food particles as he approached, then you get disconnected as he reached you.
Also, once somebody has died, the player counter loses count somehow, showing 13 when 15 players were clearly visible.

I'm investigating these now.

The usernames are growing as you eat more food. That shouldn't happen (unless name fits entirely on cell size, perhaps?)

As it is right now, even if your name overflows the cell size, it'll continue to get bigger as your cell does.

Support A/W/S/D and/or UP/DOWN/LEFT/RIGHT arrow keys.

Press W or something to fire yourself as a food. To feed other player or virus.

I'm thinking about adding an animation engine for handling some animation (split animation,...) and for faster HitTest.

But have no idea where should we calculate the animation. On server side (more complex) or on client side (much easier? any risk?)

EDIT: Appended #134

"... noticed when you eat the "food" the transition between your current size and the next size is instantaneous. Could you add the transition of the "expansion" from your current size to the new size?"

Linked with #3
It's better to have another chat style (bubble)
And we need to make a switch somewhere (config/setting page) to allow user switch between chat type.

Maybe host it on Heroku (rip free tier) or Openshift ?

i am getting a lot of problems with the new config system,

the yml is the problem?

Hi,
we are using firefox on fedora and arch linux and we can not eat each other.
it does not matter who is larger, we can not eat the smaller one.
sometimes we can not even see each other

Adding a license (MIT seems like it would fit the project best) lets a contributor know how their code will be used in the future. Could you add one?

The server is flooding the game console when a player moves and/or a food has been eaten.

With gulp and babel
#36

Maybe we should make it so the player can move in a certain area, and only move the camera when the player is close to the screen borders. As it is right now it's pretty hard to play, as in it's hard to get used to it.

1. player's move need server feedback

first, player send playerSendTarget command to server.
then server got it, calculate the new position, and send back the serverTellPlayerMove command to this player.

after the server feedback, the player can move.

If there is a big lag between player and server,
the player move will be blocked in a long time.

This should be player move first, then got the server feedback,
player modify it's position with the server feedback data.

2. The server broadcast message immediately

when a player move mouse,
the server will got a playerSendTarget command, and target data.

server do some calculate (eat food, or eat other players),
then broadcast serverUpdateAllPlayers to all connected players.

This is a bad design.

If there are 100 players connected to the server.
every player move mouse one times per second.

It means, the server will broadcast 100 times in one seconds.
And every client will got 100 times messages.

This is very overload to both server and client.

This should be done as the follows:

Server has a tick rate (maybe 10Hz. 10 times per second) to sync the whole game world to all clients.
(AOI. (area of interest ) are just ignored right now )

player send playerSendTarget to server immediately.
server do calculate, and NOT broadcast the message to other clients.

When next server tick comes, then send serverUpdateAllPlayers to all clients.

This can avoid the overload of server and client in a high rate communicate.
Server To Client rate is Fixed to the server tick rate.

Update new algorithm for hit test. To improve speed.

I have all packages (NPM,Socket,Bower, etc.). I think that I installed all of requires correctly. But I get an error like;

root@xxx:~/agar.io-clone# npm start

[email protected] start /root/agar.io-clone
node server/server.js

Config file not found!

When I try to write "node server/server.js"

root@sinankose:~/agar.io-clone# node server/server.js
-bash: /usr/sbin/node: No such file or directory

Both are not working, what should I do?

Working demo hosted on openshift:
https://pillo-nibro.rhcloud.com/

Maybe should be limit area size X x X in settings?
Now I can travel unlimited away from others...

So we can express our anger when people eat us.

We should draw a grid to background to see if player is moving or not when there are no foods on screen

I get connection refused whenever I run this, I have reinstalled the server 3-4 times now and I am still getting this error, thanks. there are no errors appearing at all it just says "listening on port :3000" here is the server I am running it on http://23.94.96.14:3000/

this works like a charm

Skins could make the game more fun to play.

maybe even where you can choose which team to join, so playing 6 vs 6 on your local lan party is possible

I think newbies should be allowed to be eaten. I feel it makes the game more fun when you start you have to work your way up

Please assign yourself to whatever issue you want solve. I want to contribute but I dont know on which one peaple are currently working.

Cell should have an invisible radius with a fixed size around it that controls its speed. Currently it's pretty annoying that when you reach the window border your cell slows down dramatically.

How to use it with public ip ?
