Hey how would you create a time delay for the for the ball to spawn?… I simply want the ball to wait 5 seconds after a goal before it spawns again and I have not been able to figure it out.

Great video i watched this after i could not figure out my mistake in Simon and my suggestion is do the impossible game. You know it the one game where you’re a rectangle and you have to jump over other rectangles.

hey this is simply just a suggestion but for your next java tutorials or just simple java programming videos that simply do not correlate with your tutorials, it would be nice if you increased the font size of your text making it easier to see. And if you do decide to do this thank you.

@Jaryt Bustard around the time of 01:08:00 when you move the code in the constructor to spawn I get an error message from my compiler telling me there is an Overridable method call in the constructor. Because of this the spawn method never gets called and my ball stopped moving. Did you not get this error?

When you were trying to score I was thinking that a unit test would be good – or some kind of bot v bot slapdown.

At 1 : 19 Why did you create the object at the start of the class? Is it ok if we just create it in the main function?

God damn, Youre amazing dude

Hello, awesome tutorial.
But i found one thing i dont understand and maybe it is a bug.When you declare winner and using a bot as openent you use the argument – if(bot) { “The Bot Wins!” }, isent that argument always true eaven if not the bot wins if you are playing against a bot? 🙂

Please! Please! Enlarge the font size as much as possible.
Thanks.

Please teach us to make some kind of simple side-scroller, that would be really cool.

Can someone just give me the text for a quick copy and paste. Apparently this is like the hardest game to try and find for download on the Internet.

Awesome! Great tutorial 😀 +sub

You could have made the font bigger, I struggle reading what you are typing, really good example of a game though

thank you for making this video man. its nice to see your approach and ive learned alot so far. however, im stuck just passed the one hour mark where you correct the randomness of the ball movement. the ball is moving smoothly but it no longer recognizes collision with the paddle. ive been going over my code for hours and nothing is sticking out to where my mistakes are obvious to me. i did make some minor changes from your code such as wording and variables in the main class ‘Pong’ (eg. jframe.setSize(width + 15,height +35) along with color variants and i also changed
//paddle size master public int x, y, width = 35, height = 150;
in paddle class
i dont know if this would affect the ball class but just to be thorough ill throw that out there. heres what my ball class is looking like

package paddleJockey;

import java.awt.Color;
import java.awt.Graphics;
import java.util.Random;

public class Ball
{

public int x, y, width = 25, height = 25;

public int motionX, motionY;

public Random random;

private Paddlejockey paddlejockey;

public Ball(Paddlejockey paddlejockey)
{
this.paddlejockey = paddlejockey;

this.random = new Random();
this.x = paddlejockey.width / 2 – this.width / 2;
this.y = paddlejockey.height / 2 – this.height / 2;

this.motionY = -2 + random.nextInt(4);

if (motionY == 0)
{
motionY = 1;
}
if (random.nextBoolean())
{
motionX = 1;
}
else
{
motionX = -1;
}

}
public void update(Paddle paddle1, Paddle paddle2)
{
int speed = 5;

this.x += motionX = speed;
this.y += motionY = speed;

if (this.y + height > paddlejockey.height || this.y < 0) { if (this.motionY < 0) { this.motionY = random.nextInt(4); } else { this.motionY = -random.nextInt(4); } } if (checkCollision(paddle1) == 1) { this.motionX = random.nextInt(4); this.motionY = -2 + random.nextInt(4); if (motionY == 0) { motionY = 1; } } else if (checkCollision(paddle2) == 1) { this.motionX = 1; this.motionY = -2 + random.nextInt(4); if (motionY == 0) { motionY = 1; } } if(checkCollision(paddle1) == 2) { paddle2.score++; } else if(checkCollision(paddle2) == 2) { paddle1.score++; } } public int checkCollision(Paddle paddle) { if (this.x < paddle.x + paddle.width && this.x + width > paddle.x && this.y < paddle.y + paddle.height && this.y + height > paddle.y)
{
return 1;
}
else if ((paddle.x > x + width && paddle.paddleNumber == 1) || (paddle.x < x && paddle.paddleNumber == 2)) { return 2; } return 0; //nothing } public void render(Graphics g) { g.setColor(Color.WHITE); g.fillOval(x, y, width, height); } } its probably something so mundane ill end up with my head in my hands for a while. java is my first language and i have only a few tutorials under my belt so far. thanks again for this video and for adding a bit of diversity to the eclipse game tutorials available. ill be sure to come back to your channel to learn more.

Hello great tutorial but i have a problem I can’t open the jar file from other computer it gives the error”couldn’t find or load main class”. Please help Jaryt Bustard.
