So I've got a for as far as playing the game goes fully working boolean array that tracks if an item has been picked up already or not, but whenever I go to inspect on my "player" and click the entry of the array I get a nullpointer exception. I'm pretty sure this should be fixable.
The error report is as follows:
Exception in thread "Timer-46" java.lang.NullPointerException
at bluej.debugmgr.inspector.ObjectInspector.listElementSelected(ObjectInspector.java:413)
at bluej.debugmgr.inspector.Inspector.update(Inspector.java:337)
at greenfoot.gui.inspector.UpdateTask.run(UpdateTask.java:45)
at java.util.TimerThread.mainLoop(Timer.java:555)
at java.util.TimerThread.run(Timer.java:505)
The code of the player that creates, calls and edits things in the array is the following. I am positive that the issue is not in the Pickup method because when I completely comment that out and inspect the player I get the same error, I added it regardless for completeness of code.
public class Player extends Actor
{
//Declaring the array for tracking what items have been picked up as well as filling it with default false.
boolean[] items = new boolean[] {false, false, false};
public void act()
{
//Calling all methods
pickup();
//This method is to check if the player can see the item to be picked up. When it does it stores this in the array.
public void pickup()
{
if (canSee(Apple.class))
{
if(items[0] == false) {
Greenfoot.playSound("item.wav");
items[0] = true;
}
}
if (canSee(Ketchup.class))
{
if(items[1] == false) {
Greenfoot.playSound("item.wav");
items[1] = true;
}
}
if (canSee(Cookie.class))
{
if(items[2] == false) {
Greenfoot.playSound("item.wav");
items[2] = true;
}
}
}
