I need help trying to sort how this collision detection in my code.
Here is my code and I have had a little assistance from various sources online but nothing with a definite explanation to it yet, but all in all I have made a lot of progress. So basically a quick thank you internet.
What I have to do is make a game where I control an object, in this case a blue circle and then touch another on screen object, in this case a yellow circle and when they touch the yellow circle will dissapear and the word "YUM" will take its place then the yellow circle will move randomly to a new location.
This is a lot like the game snake but I can't get the collision to work right and also if I did have it working I have no idea how I would update the location to a new location randomly on the screen.
here is the code:
import java.awt.Color;
import java.awt.Font;
import java.awt.Graphics;
import java.awt.Image;
import java.awt.event.KeyAdapter;
import java.awt.event.KeyEvent;

}
}

{

}

{
player.x += -10;
}

{
player.y = 20;
}

}
}

{
player.y = 450;
}

{

}
}
}

}

{

}

{

}

{

{

return true;
}

{
return false;
}
}
public javagame2()
{
addKeyListener(new AL());
setTitle("Ballon Popper");
setSize(1000, 500);
setResizable(false);
setVisible(true);
setBackground(Color.BLACK);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
public void paintcomponent(Graphics g)
{
g.setColor(Color.WHITE);
g.drawRect(pizza.x1, pizza.y1, 50, 50);
g.setFont(font);
g.setColor(Color.RED);
g.drawString("Eat the Pizza!", 350, 50);
g.setColor(Color.BLUE);
g.drawRect(getX(), getY(), 50, 50);
g.fillOval(getX(), getY(), 50, 50);
g.setColor(Color.YELLOW);
g.fillOval(pizza.x1, pizza.y1, 50, 50);
repaint();
}
public void paint(Graphics g)
{
dbimage = createImage(getWidth(), getHeight());
dbg = dbimage.getGraphics();
paintcomponent(dbg);
g.drawImage(dbimage, 0, 0, this);
}
public static void main(String arg[])
{
new javagame2();
}
}
Here is the updated code I just worked out a little bit, it does run but I'm a bit confused on how to go about removing the yellow circle once I have touched or even what to do, I tried using .intersects but that didn't seem to do anything.
