Why does this JFrame not end up being blue?

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();

	}

}

How do I put a simple self-made game on my phone?

Hi

I'd like to get my first Javascript test game onto my phone.

Do they expect .js files or HTML5?

How do I upload it - comple it to an app? Will it work on all devices? How do I accommodate different pixel dimensions in my code? - for identical gameplay on all devices, is there a stretch / affine transform?
Thanks

Hi
I think for my io game in javascript, it would help my game object layout if I knew if the game was being played on a phone or desktop.
What is the best way to do this?
Also. . . Clear the canvas for a game loop efficiently? Is Javascript rendering super-fast?
...and then place my game objects appropriately?

Thanks

Is hacking on io phone games a problem yet?

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
For a phone io game,
I'd like to be able to click/touch one part of a line, and move it.
If the HTML sends in the size of the game-window, does a phone luncher pass in its size? obviously. Is there a minimum size?
Thanks.
Are touches simply like mouse clicks? No special module?

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

Are major .io javascript games MMO's? How is the networking done?

Hi,

I've been fine-tuning my javascript for a little while, and this page below has helped me most understand everything needed for gaming. . .
but, it doesnt do networking, which I'd like to discuss...
Is slither.io / wings.io an MMO, or computer enemies? They have what seems to be a score table with different names, but I question whether they are people or not, since there seem to be so many?
Is it datagrams over TCP? Many connected servers all over the world?
Is a game like slither.io pure Javascript?

That Javascript game overview is . . .

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.

Do most javascript games avoid sound?

Hi,
if I make a Javascript game, most I see on my phone don't do sound.
Is that the norm? Avoiding sound? I couldn't see .wav or .mp3 in their code
One time ago my dad had game swirling sounds playing loud from his laptop, and the cats became very upset.

How closely can a game use a copyrighted name?

Hi

I've already angered some experts w legal questions :D - not - I know I shouldn't hope for such binding certainty w, basically, friends!
If I put in a game, a character, npc called Brad Pitt, I'd get in trouble, but how strict are they on similar names,

like, Bradd McPitt, or Ranakin Slywalker? How does a similar character look factor. Space Quest III had the Vader v Obi-Wan duel in their hangar, briefly. I'm sure Sierra got legal permission. I think I saw that if you make a character that is in all black, helmet and laser sword, that is a no-no. What about a dead ringer for an Alien? (xenomorph)
What should I know!?

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

Is Python a suitable language for a game client?

Hi
I'm curious..

I have made a few network game projects w help of sporadic legends on this site.

Now, a Python network game.

It seems Pygame can do adequate 2D gaming, side scroller / maze etc
How about a networking game client?
It looks like all the usual abilities are available.
I might make my server in Java, but my game clients in Python?

A plan?

Is Disney also ruthless about criticism, like IP?

Hi
My last Disney question concerned their ruthlessness protecting their IP.
This one concerns how seriously they take criticism.
They sued an elderly couple in Florida for $1000,000 for using an image of Mickey on their kindergarten wall.

Obviously, if they were super sensitive about criticism, Youtube would be buried in lawsuits concerning fan mega-criticism of Star Wars.
Would they be as ruthless concerning an inconspicuous site criticizing their Star wars decisions and plans?
My dad said it's just free-speech and they cant do anything (no IP infringement) I won't use any images on the site.
Thanks

For one of my classes, I have to conduct a 20 min game/activity with the class that explains how blockchain works in an easy-to-understand way. Would be even better if it has to do with marketing, as that's the class I'm in. It can be as rudimentary or as advanced as we want.

Only idea I have right now is playing a giant game of rock paper scissors where everybody frantically runs around for 10 minutes and plays & wins as many games of rock paper scissors with classmates as they can. When each game is over, both opponents have to go to the notebook in the center of the room and put a tally mark next to who won. This shows that blockchain ensures accountability, everybody documents every "transaction" that is made, and that everybody has access to the public records at all times. (Rather than just everybody keeping track of their own score, which could induce cheating.)

Any ideas? I feel like this is a fun question to answer.

Any more suggestions for my coding lessons strategy?

Hi
We talked a little about my approach to teaching neighborhood kids and adults, even, how to code.
I think we decided against going all out on Python right away. Do you still agree? I'd like to hold off on Python for a pure newbie.
K-12 focuses on Java, so I think Java for them is obvious.
I also think so, because polymorphism and class design will be important for making tablet, phone apps, as they are seriously non-novice projects. - Java will make 4 an easy transition
I'm going to start them off on Java and when they are blatantly ready, switch to Python, or their preferred device.
I could do Java and Python side-by-side?
Any suggestions?
Thanks
I'll start early next year

Hello,

How do you revert back to a previous version of Google Chrome?

Sometime yesterday I noticed a change in the appearance of Google Chrome, in that the address bar now has a light blue border as shown in the following screenshot:

My current version of Google Chrome:

However, sometime later I went to join some friends playing a game at a website called slither.io (where players compete as snakes of different colors and sizes). However, after beginning to play, I noticed that the game image was jiggling or shaking to the point that I had to turn it off. The frame of the window itself does not move but the entire image (background and players) trembles as you might expect a picture on the wall to tremble during an earthquake.

The shaking movement is accompanied by a significant lag. I have experienced lag issues in the past but they always manifest as a sudden freeze for 2-3 seconds followed by a catch-up burst to put everything into its real-time position.

Interestingly, the shaking and lag become much worse by going into a congested area (ie the more snakes in the field of view, the worse the movement), and is almost nonexistent if you are in the outskirts with no one else around.

I've searched Google quite a bit for a solution and have tried each of the following:

• Zoom in/out
• Restart Chrome
• Restart computer
• Empty the Chrome history
• Chrome > Show advanced settings > scroll down to…
