Hi,
I am working on the World of Zuul. I am adding the take item command, when I envoke it, the output prints twice!
The main class is Game, this is the take method.
public void takeItem(Command command)
(
if (!command.hasSecondWord())(
// if there is no second word, we dont know which item to take
System.out.println("Which Item 9otli ya mja9ji9?");
return;
)
String itemToBePicked = command.getSecondWord();
playerInventory.addItemToInventory(itemToBePicked);
if (playerInventory.addItemToInventory(itemToBePicked))
(
currentRoom.removeItem(itemToBePicked);
)
return;
)
method in Inventory (instance playerInventory)
public boolean addItemToInventory(String itemToBePicked)
(
//checking the weight constraint
if (canBePicked(itemToBePicked))
(
Item x = allItems.get(itemToBePicked);
itemInventory.put(itemToBePicked, x);
inventoryWeight = inventoryWeight + x.getItemWeight();
System.out.println("You have added " + x.getItemName() + "to your inventory");
return true;
)
else if ((game.checkAvailability(itemToBePicked)))
(
System.out.println("You have exceeded the maximum weight");
return false;
)
else
(
System.out.println( itemToBePicked + " is not present in the current room");
return false;
)
public boolean canBePicked(String itemToBePicked)
(
Item x = allItems.get(itemToBePicked);
int totalWeight = x.getItemWeight()+ inventoryWeight;
if ((game.checkAvailability(itemToBePicked))||(totalWeight <= maxWeight))
(
return true;
)
else
(
return false;
)
)
and the checkAvailability in Game:
public boolean checkAvailability(String itemToBePicked)
(
return currentRoom.checkItem(itemToBePicked);
)
and the method from Room (instance currentRoom)
public boolean checkItem(String itemToBePicked)
)
int n=items.size();
for (int i=0 ; i<n ; i++){
Item x = items.get(i);
if ((x.getItemName()).equals(itemToBePicked))
(
return true;
)
(
return false;
)
couldnt figure out why the output line always appears twice! like:
you have added computer to your inventory
you have added computer to your inventory
any help is much appreciated!
