Nice works great! Looking forward to how you implement the updates.

This is some fine as3 code !!

I'm using your code for my game project, and it's very useful!! thx!

I could adapt it without too much problems! (I'm just starting to code in as3- started this Oct)

I arrive where i'm writing the hitTest Items in level (player run to an item in the item container (your class/movieclip "level")) and i want to check if there's empty slots in the inventory when that happens.
So I found you're function in Inventory.as :

Quote:

---

public function findEmptySlot():Slot

---

But it keeps returning that it's FULL.

my inventory has 6 slots and i1 = empty, i2 = full, i3 = full, i4 = full, i5 = empty, i6 = empty. So it should return "i1" or [Object Slot] and close the function.

I verified that i had the good inventory variable from the DisplayManager (and not just the class Inventory) by using the hasitem():Boolean function from Slot.as :

Quote:

---

var _empty_Slot:Slot = _inventory.findEmptySlot();
trace (_empty_Slot);
var _Slot1:Slot = _inventory.getSlot("i1");
trace (_Slot1.hasItem());
var _Slot2:Slot = _inventory.getSlot("i2");
trace (_Slot2.hasItem());

---

_empty_Slot returns null
_Slot1 returns false
_Slot2 returns true

so I'm confused :confused:

EDIT::: Here, just before posting, I figured it out!!! :)

Seems like the file Inventory of your package (at least the one I have, the original copy not the one I've been modifying.) has an error there:

CLASS: com.freeactionscript.inventorySystem.display.conta iner.Inventory

around line 140.

Quote:

---

public function findEmptySlot():Slot
{
var i:int;
var tempSlot:Slot;

for (i = 0; i < _slots.length; i++)
{
tempSlot = _slots[i] as Slot;

if (tempSlot.hasItem == false)
{
return tempSlot;
}

}

trace("Inventory Full! No empty slots.");
return null;
}

---

I replace it by tempSlot.hasItem() == false

Check if your file on your site has this or not.

There, I continue my work, enjoying your package.. !! if i found other errors I'll post them here or send you an pm?

Cheers!

Hi JessiJames,

I'm glad you like the script!

Sorry about the bug - I don't think I was using the get empty slot function, so that's probably why it was left broken.

Replying here is just as fine a place as any. I'll make sure to apply your fix and give you the proper credit next version. :thumbsup:

Thanks bud,
