Any tips for making the combine button visible only if the selected items are in the recipe?

I'm throwing all kinds of if statements at it, but I'm not getting the result I want.

First of all I want to say thank you so much for putting this up!
I've been tearing my hair out trying to figure out how to get my inventory to work and this has made it so much easier! :D

I do have a couple of questions though that hopefully someone might be able to help me with:

1) I have a side image that is constantly on display that shows the statistics, etc. Is there a way to make the image of the selected item to show up on this sidebar as well?
(I've attached a quick picture to clarify what I mean :) )
2) At the moment I have three buttons: hair accessories, clothes and shoes. Is there a way to organise the items so they will show up in different screens? I was hoping that, for example, when I click on the hair accessory button only the items that have to do with hair will pop up. Or would I need to create a new "inventory" for each screen?

3) Is it possible to add a statistics boost to the items the way you added a hp boost? So if, for example, I equip that hair accessory, my character will get +3 charisma and +3 cuteness. I've got my statistics defined as "$ CHA = 0 #Charisma" and so on at the moment in case that changes things...

Sorry if they're really simple questions but I haven't got much experience when it comes to Ren'Py ^^'

Hi leon,
I am trying to use your inventory in my game (Thank your for sharing it!) but I am having a bit of a problem...
I want to create a point and click adventure game and therefore need the possibility to click on an item displayed on screen to add it to the inventory.

My item looks like this, when clicked it gets removed and theoretically added to the inventory:

Code: Select all

screen item_test1:
        imagebutton auto "images/test_button_%s.png" action [ Hide("item_test1"), inventory.add(stone)] align (.52,.58)
The only problem is as long as the imagebutton is visible endless stone's get picked up without ever pressing on it, any idea? Another interesting thing is when selecting one of the stones in the inventory, all of them get selected and they only get more when you open the inventory; leaving it closed and then picking up the item always results in them being there three times.

EDIT: Figured it out myself. Sometimes reading more docs helps :D

Code: Select all

Function(inventory.add, stone)

Excellent code, helped so much for understanding inventory screen.

But, could you please direct me to the part of the script that organizes displayed items.
For example if I have 3 items in my inv, and get another one, I want new item to come first, and the rest of them moved to the next inv spaces.

EDIT: Nevermind, I got it!

Hi when I try and click combine it get this error log

I'm sorry, but an uncaught exception occurred.

I'm back! (^_^)v

The biggest issue I'm having with this is that all of the items are selectable.

If two items are not in the same recipe I want the selected idle images to disappear.
(ie the glow that tells you an item is selected...?)

I want a maximum of two items to be selectable at a time.

Code: Select all

No code posted because I'm not sure if this is an inventory screen issue, or a Function thing or what!  :( 

Tips please!

First of all, thanks for posting this demo. It was very useful to play around with it.

Now on with a little issue I had while "playing" with it. I didn't like the "next page" behaviour, more specifically I didn't like that it kept on cycling between pages without even changing its name into "prev page" or something like that...So I've tried to change it.

given that:

Code: Select all

init -1 python:

    inv_page = 0 # initial page of teh inventory screen
I've added a prev_page button:

Code: Select all

    $ next_inv_page = inv_page + 1
    $ prev_inv_page = inv_page -1 #my code
    if next_inv_page > int(len(inventory.items)/12):
        $ next_inv_page = 0
    if prev_inv_page < int(len(inventory.items)/12): #my code 
        $ prev_inv_page = 0
and of course, added the buttons accordingly:

Code: Select all

        if len(inventory.items)>12:
            textbutton _("Next Page") action [SetVariable('inv_page', next_inv_page), Show("inventory_screen")] xpos .475 ypos .83
            textbutton _("Prev Page") action [SetVariable('inv_page', prev_inv_page), Show("inventory_screen")] xpos .575 ypos .83
Now: the prev_page button works perfectly, but that was an easy call: since every page contains 12 items only, if the items are less than 12, it necessarily means that it has to go back until it gets to the initial page and stop.
The same (obviously) doesn't apply to next_button, which keeps on cycling between pages without stopping on the last page containing items (like I would, instead).

Any hints on how can I fix this "dynamic" page logic for the next_page button?

fixed that :P
I'm sure there must be a more code-friendly/good looking way to achieve this, but I simply fixed it by adding this condition:

Code: Select all

    if next_inv_page < int(len(inventory.items)/12):
        $ next_inv_page = 1 
so the next_page button will cycle forward until it gets to the last page containing items. I've posted it for the sake of helping someone as lost as I was. ;)

I've been playing around with the code a bit, but I can't figure it out... Whenever you use an item, I'd like for it to jump back to the inventory screen instead of calling the screen to show the inventory button. How can I go about doing this?

I don't quite understand WHY it's going there. I'm using events based off the item used, so my defined code looks like this

Code: Select all

def use(self): #here we define what should happen when we use the item
                renpy.call_in_new_context ('hammer_event')
## Seems that it hits this point, then calls back the inventory_button screen.

label hammer_event:
    "You dance around with the hammer"
    "Nobody knows!"
    $ inventory.drop(hammer)

From my understanding, when it hits return, it's jumping back to whatever should come after the call_in_new_context, but using the sample code provided, there's nothing there except for other elif/else statements about items used, and so far, all my attempts to make it jump back to the inventory screen properly have failed. I've gotten it to loop through the inventory before, but that's not quite right x3

So much to learn, but threads like this one helps so much. I really love then someone has asked a question, figured it out on there own, and updated their post with the answer. That's great for people like me that are so new to this program. Thanks
