Hi everyone,

RobPos.java
package robotmax;
import java.awt.Color;
import java.awt.Graphics;
import javax.swing.JPanel;
public class RobPos extends JPanel{
int tilex=0,tiley=0;
public RobPos(){
this.setBackground(Color.black);
}
public void paintComponent(Graphics g)
{
super.paintComponent(g);
g.setColor(Color.BLACK);
}
public int getTileXRobPos()
{
return tilex;
}
public int getTileYRobPos()
{
return tiley;
}
public void setTileXRobPos(int x)
{
tilex= x;
}
public void setTileYRobPos(int y)
{
tiley = y;
}
public static void main(String[] args) {
// TODO Auto-generated method stub
}
}
I need to create a robot simulation with grid map and a robot (which takes up 4 grid) and have to simulate it moving in the map.
My idea originally is:
to create 4 robot class object, each with methods like setTileX, setTileY, getTileX, getTileY for the purpose of getting the row and col of the position of the robot.
And for each object, I wanted to set background as yellow (So total there are 4 grid of yellow on the map simulating the robot), and every time “Down” button is pressed (using key listener), the object will move 1 level down.
Pls advise, thank you!
