Thread: Rushhour - X and Y Positions

Hello Guys!

I have to make a Rush hour game for my project. The basic idea of Rush hour is to "Unstuck" you car and get it to the exit by moving other vehicles out of the way. My problem is that I want to create multiple vehicles of the same type ( By using a factory ) and have them start at different X or Y positions depending on the vehicle. As an example I will use a "Bus":

Now, the idea is that the bus can ONLY move in the Y directions and is stuck to it's X position. The problem is, because I use the same factory for the busses they snap to the same X position as soo as I start moving them ( which at the moment is x = 0 ). So what I want them to do is stay at the x position they are at while I a moving the Y direction. Here is my code for the bus: (All my methods, classes etc. are in Dutch, sorry for that)

package RushHourSpel;
 
import java.awt.Color;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;
import java.awt.event.MouseMotionListener;
 
public class Bus extends SpelFiguren implements MouseMotionListener {
 
	private int clickedY, clickedX;
 
	public Bus(int x, int y)
	{
 
		this.setSize(lengthBusX, lengthBusY);
		this.setBackground(Color.BLUE);
		this.addMouseMotionListener(this);
		this.setLocation(x, y);
 
	}
 
 
	@Override
	public void mouseDragged(MouseEvent e)
	{
		int muisY = e.getY();
		int verschilY = clickedY - muisY;
		int busY = this.getY() - verschilY - 75;
		//int muisX = e.getX();
		//int verschilX = clickedX - muisX;
		//int busX = this.getX() - verschilX - 20;
 
		this.setLocation(LocationBusX, busY);
		//  Vanaf Hieronder Border Collisions
 
		if(busY > 350)
		{
			setLocation(LocationBusX, 350);
		}
 
		if(busY < 0)
		{
			setLocation(LocationBusX, 0);
		}
 
		// Vanaf Hieronder Collisions met andere spelfiguren.
		try
		{
			if(collisionRodeAuto())
			{
 
				this.setLocation(LocationBusX, 80);
				System.out.println("Collision!");
			}
 
			if(collisionAuto())
			{
 
				this.setLocation(LocationBusX, 250);
				System.out.println("Collision!");
			}
 
 
 
		}
		catch(NullPointerException ex)
		{
 
		}
	}
 
 
 
 
 
	public boolean collisionRodeAuto()
	{
 
		return SpeelLevels.rd.getBounds().intersects(this.getBounds());
 
	}
 
 
	public boolean collisionAuto()
 
	{
 
		return SpeelLevels.auto1.getBounds().intersects(this.getBounds());
 
	}
 
	@Override
	public void mouseMoved(MouseEvent e)
	{
	}

				BusX = 160 + i * 60;
				bus2 = new Bus(BusX, 50);
				bus2.setLocation(BusX, 50);

I don't really understand your question or problem. What does using a factory have to do with snapping all vehicles created to x = 0? If you don't want that to happen, don't set x = 0 in your factory or any of its methods.

I made a video with the problem showing, hope this helps to understand it better. So the left bus needs to stay on it's X position, but it snap to the other bus's X position. now I know where the problem is coming from, but I don't know how to solve it without making a entire different class for the second bus.
