What do you think? Let me know.
Sounds good, i'll have to give it a try. I'll add it to my site soon.
WOW!!!!!! Like Diablo inventory!!!!! I never thought it could be possible!!!!! Thankyou!!!!
Wow thats awesome! Nice Sigon set :D!
amazing. Nice job, Besh!
Heh...now that I actually realize what this is it's pretty neat. Nice work.
Yeah, Grid-Based is not self-explanatory but that is the name given in the coding constest.
Thanks to all to appreciate my work!!!
sorry to pop up this old thread but Im triyng to use this module wits AGS 3.01 and I have this error
Quote
An error has occurred. Please contact the game author for support, as this
is likely to be a scripting error and not a bug in AGS.
(ACI version 3.01.1017)
in "GridInventory.asc", line 397
from "GlobalScript.asc", line 360
Error: String.Substring: invalid index
line 397 is
id = this.itemId.Substring(pos * 3, 3);
I dont understand what this code mean ant to what its related.
any clue or suggestion?
Maybe its because I'm using the verbcoin template but not the inventory from it?
when I load the demo game in 3.01 there is no problem so I certainly miss an important point in the configuration but cant figure which one.
EDIT problem solved it was just itemheight anditemweight which were not correctly setted
I have this error

Error: run_text_script1: error -6 running function 'oBarreau_Interact':

OK

line 56 is : janeInv.AddItem(iBarreaucoupe);
I can add item to inventory only in game_start.
This is not very usefull for a game not being able to add inventory item in room.
So i guess i have miss something on the use of this module.
Have you tried adding the item to Your Gridinventory instead of the character?
GridInventory.AddItem(iBarreau);
Thats not possible to do that, it must be an instance of the structure.
Problem is i cant use the instance ouside game_start.
I tryed to add in room script
GridInventory janeInv;
but it give me the error above.
so if someone as any clue ;)
I have finally solved my problem
i had to export and import the definition of my character inventory.
in global script
export janeInv;
in global script header
import GridInventory janeInv;
now it works :)
The idea for such a module is amazing! I love it so much! Thank you for creating it, Besh!
Not only Diablo I and II work with this kind of inventory, it is also used in epic games such as Arcanum and Resident Evil 4! Therefore the need of such an inventory is unquestionable. Once I finish my current game I will start going into this one by using it!
For now I have discovered 2 issues about your module.
The first problem is that when the player selects an item (the mouse cursor changes) and then selects the “return to select button†on the bottom of the inventory (next to ok). The mouse cursor returns to normal without returning the picked item into its original inventory position. Thus the item is lost! (I just imagine that to happen in the real Diablo II after finally finding a good weapon)
Secondly there is another thing that diminishes its use, as discussed in this forum: http://www.adventuregamestudio.co.uk/forums/index.php?topic=8119.0
One can't drop Inventory Items at the moment!
