Hi
I am having no trouble generating legal moves on the board state in my experimental Java chess server.

I'd like to know how best to send the legal moves list byte[] to each client.
My move struct constructor looks like this:

public ChessMove (int _x1, int _y1, int _x2, int _y2, char chPiece) {  
              //chess characters are upper-case white, lower-case black, RNBQKBNR and rnbqkbnr,  PPPPP and ppppp
		x1=_x1;
		y1=_y1;
		x2=_x2;
		y2=_y2;
		pieceChar=chPiece;

Select all Open in new window

I can convert integers to 2 bytes, no problem...
cast integer to (byte) and then

byte SecondByte(int x) {
			return (byte) ((x & 0x0000ff00) >> 8);
		}

Select all Open in new window

and then [] to int:

static int intFromBytes(byte firstByte, byte secondByte) {
			if ((secondByte&0x80)==128) {
				//negative number
				return (int) ( (firstByte&0x000000ff)| ((secondByte&0x000000ff) << 8) | 0xffff0000 );
			} else {
				//Positive number
				return (int) ( (firstByte&0x000000ff)| ((secondByte&0x000000ff) << 8) );
				}
		}

I'm not worried about cheating, because the client sends back the index of the move in the move array list they want to play to the server.

What is the most efficient way to encode my list of legal moves for each client on the client-server messaging?
Do I not need to bother, and have the move generator on the client as well?
Cheating, altering data in memory won't help/matter. If they don't send back a decent Legal move's index to the server, it's their fault!
There are many ways to approach this, but I'd like "approval." My RTS server happened, and I'm certain this plan sounds good.
?

Thanks

Hi
I've been flicking my eyes on this agar clone server, and it is just a simple, in my opinion, TCP iostream / javascript game.
I'm glad that the agario game state / universe is centralized.

Do you agree? . . . here

Where do you suspect they house their server?

Can there be any downsides to making my game-server in Java, not .js? I have my first game ideas ready to be cranked.

Thanks

Hi
If I make my game server in Java, with TCP/IP HELO, START and in-game messages, game runs in browser, javascript to my server,
what can I expect as the worst from the unavoidable hackers and miscreants? Floods..
DSS attacks. Are they detectable? Stoppable? Google suggested they are stoppable. I will be using a Godaddy professional private server.
Floods will be a certainty if my game escalates. It would  suck, because there will be prizes in contention.
Do Blizzard and Microsoft weed these out? Is this how the old disconnect-hacks worked?

Thanks

Hi
I'm surprised this JFrame didn't work, an I wonder why. It doesn't draw any blue. What might I have done wrong?

import java.awt.Color;
import java.awt.Graphics;

import javax.swing.*;


public class Merrywin extends Thread{
	
	JFrame jFrame;

	public Merrywin() {
		
		
		
		start();
	}
		
		

		
		
		
	

	public void run() {

		System.out.println("Hi");
		jFrame = new JFrame();   
		jFrame.setBounds(10, 0, 1125, 2436);  
		jFrame.setVisible(true);
		
		Graphics G = jFrame.getGraphics();
		G.setColor(Color.BLUE);
		G.fillRect(0, 0, 1000, 2000);
			
				

	}
		
		
	public static void main(String[] args) {
		System.out.println("Maine");

			Merrywin m = new Merrywin();

	}

}

Hi
If I am going to focus on phone / io games, I'd like to know about security issues like hacking, which is unavoidable w online games. I created a successful Authoritative Java RTS server. It could not be hacked. Slither.io has all game data local..  Are people messing around with slither, etc?

Surely, if they start my game from an io site - or on my business hosting private server, it is my official client code. - it is not their hack. Now they can hack my game variables, but can they simply make a map hack? Must I still have an authoritative server? I read that some games are just clients - update each other on all activity, no in-game server, just clients.

Is hacking something I ned to be vigilant about, yet?

Will it ever be?
Thanks

Hi

What do you think of me having in my game, a character with a sword, in a black cloth suit, just like Anakin on Mustafar, but he is called Pepe the Swindler? with a colorful sword?
How could Disney / LFilm kill me? I know them, they'd murder me. You can not copyright a story. How about a giant droid thing slightly similar to  general grievous? if I called him unpleasant robot.
There is fair use for situations like this, but does Disney / LF care?

Thanks

Hi.
I think my <script> learning curve would be most boosted right now, if I could see a .js /htm that allows a player to move a circle /square/dodecahedron / pterodactyl around the screen with a finger.

Also, I see some coders do their scripting inside html and <script> tags and others in .js
Is it inconsequential? or simply a preference.

Thanks

Hi
I'm going to start making Javascript games (thanks, ye legends who helped me before! - I have my server being written in Java)

For my game client on phone, etc in Javascript,
Is there a good page for me to see how a JS game is best laid out, handlers, data-structures, resource loading, game loop,  a road map? I may have
seen a YT for it, but can't re-find it.

Thanks

Hi
I'm trying to get javascript to run in Atom Editor,
bu there is no compile or run button / menu Item

I have the following packages installed... (83 !) of them.
script 3.18.1
script-runner 2.3.1

dozens of others to get this one working
Should there be a compile/run menu item / button?
Thanks

Hi,

So, I'm going to use Javascript for my game client. I can do the server in Java, thanks to local legends. I need a listener waiting for user directives on the game window and sending an activity packet for each frame.
It's going to be a platform style multiplayer.
I'm going to treat it like an RTS, UDP over TCP, for fast delivery of info in UDP packets over reliable TCP sends.
Does Javascript block for GameWindow activity? How is it queried?

What should I know? I got it done in Java be4 w Threads
Thanks
