Circle to move when mouse clicked Java
- by Myt
So I am really new to Java and I need a circle to move around JFrame when it's clicked, but the circle has to get random cordinates. So far this code generates a new circle every time it's clicked, but all the other circles stay there aswell, but I only need one circle to move around the frame. So maybe someone can help me a little :)
public class test2 extends JFrame implements MouseListener {
int height, width;
public test2() {
this.setTitle("Click");
this.setSize(400,400);
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
this.setVisible(true);
addMouseListener(this);
width = getSize().width;
height = getSize().height;
}
public void paint (Graphics g) {
setBackground (Color.red);
g.setColor(Color.yellow);
int a, b;
a = -50 + (int)(Math.random()*(width+40));
b = (int)(Math.random()*(height+20));
g.fillOval(a, b, 130, 110);
}
public void mouseClicked(MouseEvent e) {
int a, b;
a = -50 + (int)(Math.random()*(width+40));
b = (int)(Math.random()*(height+20));
repaint();
}
public void mouseReleased(MouseEvent e){}
public void mouseEntered(MouseEvent e){}
public void mouseExited(MouseEvent e){}
public void mousePressed(MouseEvent e){}
public static void main(String arg[]){
new test2();
}
}
