Can anybody figure out why my UserInfo code isn't working? I'm using it to save the players progress. It will save if you just reset the scenario, but not if you refresh the page. Here's the link and the relevant code.
import greenfoot.*; // (World, Actor, GreenfootImage, Greenfoot and MouseInfo)
public class MenuWorld extends World implements KeyInputObserver {
private final LevelButton[] buttons;
/**
* Constructor for objects of class MenuWorld.
*/
public MenuWorld() {
super(700, 700, 1);
buttons = new LevelButton[2];
prepare();
if (UserInfo.getMyInfo() != null) {
for (int i = 0; i <= UserInfo.getMyInfo().getInt(0); i++) {
buttons[i].unlock();
}
} else {
throw new IllegalArgumentException("UserInfo required");
}
}
/**
* Prepare the world for the start of the program.
* That is: create the initial objects and add them to the world.
*/
private void prepare() {
buttons[0] = new LevelButton(1, true);
buttons[1] = new LevelButton(2);
addObject(buttons[0], 100, 100);
addObject(buttons[1], 300, 100);
}
public void startLevel(int level) {
switch (level) {
case 1:
Greenfoot.setWorld(new GameWorld1(this));
break;
case 2:
Greenfoot.setWorld(new GameWorld2(this));
break;
}
}
public void unlockLevel(int level) {
if (level < buttons.length) {
buttons[level].unlock();
if (UserInfo.getMyInfo() != null && UserInfo.getMyInfo().getInt(0) < level) {
UserInfo.getMyInfo().setInt(0, level);
}
}
}
}
