Displaying multiple images through a loop

#1 Post by useless19 » Fri Dec 28, 2018 10:27 am

I'm trying to display a hand of (randomly picked) cards. What I've found so far either can't find the image location, or thinks the cards are the same and only displays one at a time.

For example:

Code: Select all

$ space = 1.0 / len(player_hand)
$ i = 0
while i < len(player_hand):
    transform current_card_placement:
        xalign space * (i+1)
        yalign 0.5
    $ card_placement = space * (i+1)
    $ card_dir = "images/" + player_hand[i] + ".png"
    show expression card_dir at current_card_placement as i
    $ i += 1
which displays the cards using the right images and spacing, but fails to display more than 1 card at once. If I remove the 'as i' it does the same.

And:

Code: Select all

python:
     space = 1.0 / len(player_hand)
     for i in range(len(player_hand)):
         card_placement = space * (i+1)
         card_dir = "images/" + player_hand[i] + ".png"
         renpy.show(card_dir, at_list=[Position(xpos=card_placement, ypos=0.5)])
which appears to give me multiple images at once, but can't find the image location and uses the default renpy silhouette, so I'm unsure if it would actually display all the cards at once. Removing the '+ ".png"' doesn't help.

Is there a way to do this in renpy? Otherwise, is there a way to do this in python?

Firstly, I've not tested any of this, so it is mostly just pointers...

I'd suggest defining the transform during init and passing in parameters during the loop:

Code: Select all

transform current_card_placement( card_num, hand_size ):
    xalign int(card_num * hand_size)
    yalign 0.5

label start:
    $ i = 1
    while i <= len(player_hand):
        $ card_dir = "images/" + player_hand[i] + ".png"
        show expression card_dir at current_card_placement( i, len(player_hand) )
        $ i += 1
Note: I removed the aliasing as aliasing to i does not alias to 1,2,3 etc, it aliases to a displayable referenced as "i"

I'd strongly suggest putting this part of your code as a screen though and maybe using a grid or hbox to separate the elements.

Code: Select all

screen show_hand( player_hand = ['king', 'queen' ] ):
    hbox:
        for card in player_hand:
            add "images/[card].png"

Thanks! I'll look into that and see how it goes.

Using a screen seems to be the way I need to go. I knew there had to be a simpler way, thanks!
