How to get the name of an object from another class in Java
I am using Greenfoot IDE and I have World Class and Boat class and Exit class
In the "Boat" class, I have a constructor that defines the boat (which type of boat and which photograph).
Boat code:
public class Boat extends Actor
{
private int size;
private int speed;
private int slow = 1;
private boolean leeg = false;
private int id;
private int time;
public void act() {
MoveBoat();
MoveMouse();
ExitHarbor(time);
Dock();
Colission();
}
public Boat(int newSize, int i, int t) {
size = newSize;
id = i;
time = t;
setImage(id);
}
public void setImage(int i) {
if (!leeg) {
setImage(new GreenfootImage("Boat"+i+".png"));
}
else {
setImage(new GreenfootImage("Boatleeg"+i+".png"));
}
}
}
Inside the Exit class, I have a constructor that defines another Exit
Output:
public class Exit extends Actor
{
private String color;
private int points;
/**
* Act - do whatever the Exit wants to do. This method is called whenever
* the 'Act' or 'Run' button gets pressed in the environment.
*/
public Exit(String kleur) {
color = kleur;
setImage(kleur);
}
public void setImage(String kleur) {
//Game1 game = getWorld().getObjects(Boat.class);
setImage(new GreenfootImage("exit"+kleur+".png"));
}
public String getColor()
{
return color;
}
}
In the World class I added 3 different boats and 3 different exits to the so-called "world" of green color with different parameters. Now I have 3 different boats and 3 different exits.
World:
public class Game1 extends World
{
/**
* Constructor for objects of class Game1.
*
*/
public Game1()
{
// Create a new world with 600x400 cells with a cell size of 1x1 pixels.
super(900, 900, 1);
prepare();
}
public void prepare()
{
Exit exit1 = new Exit("paars");
addObject(exit1, 885, 615);
Exit exit2 = new Exit("groen");
addObject(exit2, 885, 472);
Exit exit3 = new Exit("geel");
addObject(exit3, 885, 340);
Boat boat1 = new Boat(10,1,700);
addObject(boat1, 500,61);
Boat boat2 = new Boat(20,2,500);
addObject(boat2, 800,61);
Boat boat3 = new Boat(30,3,300);
addObject(boat3, 650,61);
}
}
The problem I am facing at the moment is that I will not indicate 1 boat exit until 1. To clear it anymore, I donβt want boat 1 to be able to only interact with "Geel" Exit (or exit1) ...
I've already tried some code, but I can't seem to get it to work.
Trial code:
if (id == 1 && "geel".equals(exit.getColor()))
I think I can get it to work with this, if only I need to get objects from the World class or the Boat class to do this, I don't know how? I tried
Actor boat = (Actor)getWorld().getObjects(Boat.class).get(0);
But this doesn't return 3 different Boats (including their object (variable) names)
Are there any suggestions?
ps This is more code, but I only showed the code that is needed for this problem
after Reactions I've tried but I'm stuck again.
public void ExitBoat(Exit exit, int size) {
this.exit = exit;
System.out.println(exit);
/* if(exit == exit1 && size == 10) {
System.out.println("jdjdf");
}*/
}
public Boat(Exit uitgang, int newSize, int i, int t) {
exit = uitgang;
size = newSize;
id = i;
time = t;
setImage(id);
}
now i'm stuck again, i dont know how to call the method with correct parameters in my void public action.
