Problems with Rock, Paper, Scissors JApplet
Hello everyone, I'm having some issues with my rock, paper, scissors JApplet program. Of course I have it "extends Applets" from the beginning of my class and I realized that this wasn't the same as JApplet. After I changed "Applet" to "JApplet", when I ran it, it doesn't look like of what I had before I changed it to "JApplet". When I have "Applet", everything looks fine. So I'm assuming I need to change something around within my code. Here is my code and please let me know as to what I need to change for the program.
import java.awt.*;
import java.applet.*;
import java.awt.event.*;
import java.net.*;
import javax.swing.*;
public class RPS extends JApplet implements ActionListener
{
private Button rockButton;
private Button scissorsButton;
private Button paperButton;
private String buttonPressed = "";
private int computerValue = -1;
private int myValue;
private int playerScore = 0;
private int computerScore = 0;
private int drawScore = 0;
private Image img1;
public void init()
{
loadImage();
rockButton = new Button("Rock");
scissorsButton = new Button("Scissors");
paperButton = new Button("Paper");
add(rockButton);
add(scissorsButton);
add(paperButton);
rockButton.addActionListener(this);
scissorsButton.addActionListener(this);
paperButton.addActionListener(this);
}
public void loadImage()
{

img1 = getToolkit().getImage(url);
}
public void actionPerformed(ActionEvent event)
{
buttonPressed = ((Button)event.getSource()).getLabel();
computerValue = randomNumber012();
translator(buttonPressed);
repaint();
}

{

rockButton.setSize(70,35);

}

{
g.drawString("Computer's Pick: Scissors", 350, 60);
}
else if(computerValue == 2)
{

}
}

}
}
public void winner(Graphics g, int cv, int mv)
{
if(cv == -1)
{
g.drawString("", 200, 100);
}
else if(cv == mv)
{
g.drawString("Draw", 200, 250);
drawScore = drawScore + 1;
}
else if(cv == 0 && mv == 1 ||
cv == 2 && mv == 0 ||
cv == 1 && mv == 2)

g.drawString("Computer Wins", 200, 250);

}
}
Thanks! :)
(Note: Please ignore any statements that involves with the images.)
What I can see from the picture, is that you need to clear your screen on a repaint().
Two ideas: - Call super.paint(g); in the first line of your paint method. This is the paint method of the super class, it might help. - Call a clearRect(0,0,getWidth(), getHeight());. This clears the screen, and might do the job.
Let me know if it works.
Ahh, I see now. At first, I found out that I needed to have the Container variable for it as well as changing the "Button" to "JButton". So I had to change some stuff around in there and I thought that would work, but it was giving me the exception. But when you mentioned the super.paint(g), I've added that and it works! Here is what I have now:
import java.awt.*;
import java.awt.event.*;
import java.net.*;
import javax.swing.*;
public class RPS extends JApplet implements ActionListener
{
Container c;
private JButton rockButton;
private JButton scissorsButton;
private JButton paperButton;
private String buttonPressed = "";
private int computerValue = -1;
private int myValue;
private int playerScore = 0;
private int computerScore = 0;
private int drawScore = 0;
private Image img1;
public void init()
{
c = getContentPane();
loadImage();
rockButton = new JButton("Rock");
scissorsButton = new JButton("Scissors");
paperButton = new JButton("Paper");
c.add(rockButton);
c.add(scissorsButton);
c.add(paperButton);
rockButton.addActionListener(this);
scissorsButton.addActionListener(this);
paperButton.addActionListener(this);
}
public void loadImage()
{
URL url = getClass().getResource("rock.jpg");
img1 = getToolkit().getImage(url);
}
public void actionPerformed(ActionEvent event)
{
buttonPressed = ((JButton)event.getSource()).getLabel();
computerValue = randomNumber012();
translator(buttonPressed);
repaint();
}
public void paint(Graphics g)
{
super.paint(g);
rockButton.setLocation(20,260);
rockButton.setSize(70,35);
paperButton.setLocation(210, 260);
paperButton.setSize(70, 35);
scissorsButton.setLocation(380, 260);
scissorsButton.setSize(90, 35);
computerChoice(g);
winner(g, computerValue, myValue);
g.drawString("Player's Wins: " + playerScore, 10, 20);
g.drawString("Computer's Wins: " + computerScore, 180, 20);
g.drawString("Draws: " + drawScore, 400, 20);
g.drawString("Your Choice: " + buttonPressed, 20, 60);
g.drawString("Computer's Pick: ", 350, 60);
g.drawImage(img1, 20, 100, this);
}
int randomNumber012()
{
return (int)(Math.random()*3);
}
/*
public void actionPerformed(ActionEvent e)
{
Gra
if(e.getSource() == rockButton)
{
g.drawString("Player's Pick: Rock", 20, 60);
}
}*/
/*public void playersChoice(Graphics g)
{
if(rockButton.isPressed())
{
g.setColor(Color.black);
g.drawString("Player's Pick: Rock", 70, 80);
}
if(paperButton.equals("Paper"))
{
g.setColor(Color.black);
g.drawString("Player's Pick: Paper", 70, 80);
}
if(scissorsButton.equals("Scissors"))
{
g.setColor(Color.black);
g.drawString("Player's Pick: Rock", 70, 80);
}
}*/
public void computerChoice(Graphics g)
{
if(computerValue == 0)
{
g.drawString("Computer's Pick: Rock", 350, 60);
}
else if(computerValue == 1)
{
g.drawString("Computer's Pick: Scissors", 350, 60);
}
else if(computerValue == 2)
{
g.drawString("Computer's Pick: Paper", 350, 60);
}
}
public void translator(String s)
{
if(s.equals("Rock"))
{
//Graphics g = getGraphics();
//g.drawString("Player's Pick: Rock", 70, 60);
myValue = 0;
}
else if(s.equals("Scissors"))
{
//Graphics g = getGraphics();
//g.drawString("Player's Pick: Scissors", 70, 60);
myValue = 1;
}
else if(s.equals("Paper"))
{
//Graphics g = getGraphics();
//g.drawString("Player's Pick: Paper", 70, 60);
myValue = 2;
}
}
public void winner(Graphics g, int cv, int mv)
{
if(cv == -1)
{
g.drawString("", 200, 100);
}
else if(cv == mv)
{
g.drawString("Draw", 200, 250);
drawScore = drawScore + 1;
}
else if(cv == 0 && mv == 1 ||
cv == 2 && mv == 0 ||
cv == 1 && mv == 2)
{
g.drawString("Computer Wins", 200, 250);
computerScore = computerScore + 1;
}
else
{
g.drawString("You Win!", 200, 250);
playerScore = playerScore + 1;
}
}
}
So far, everything is the same. Just some stuff I had to change around. Thanks for your help! I appreciate it! :)
