inventory items

[bozance]

Hello,

Currently I do the following to display inventory items:

1. In INIT section, I have $inv=[]
2. To display inventory near bottom of screen, I entered:
screen statsinv:
hbox:
text("{color=#5f9ea0}Inv: %s{/color}" % inv)
3. When an item is added, I have $inv.append("watch") for example.

The Inventory starts out actually displaying the brackets, and puts a single-quote around each item.

So the game displays the following:
Inv: ['watch', 'ring']

I just want it to display
Inv: watch, ring

Is there a way to do that?

Thanks

Since 'inv' is a list, when you interpolate it into a string, it uses Python's default string representation of a list, which includes the square brackets and the quotes.

One thing you can do is use the 'join' method of a string, which takes a sequence (like a list) as a parameter and joins all the items in the list together using that string between each one. So, for example:

Code: Select all

>>> inv = ['watch', 'ring']
>>> print "Inv: " + str(inv)
Inv: ['watch', 'ring']
>>> print "Inv: " + ", ".join(inv)
Inv: watch, ring

The 'join' function is actually a method on a string instance itself - so you need to provide the string you want to join, then a dot, then the function name 'join' and then the parameter list, which is a little different from most function calls. So:

Code: Select all

  ", ".join(inv)

is using the string instance:

Code: Select all

", "

and calling the method join with 'inv' as a parameter

Thanks--though I'm not sure exactly where to put that in my script.

If I have the following in the INIT section, where exactly would I put the join stuff? Can you enter it in where it would belong in the example below?

Sorry if my question is too basic. I'm an English major and anything beyond jump and basic if statements and I'm screwed.

Init:
screen statsinv:
hbox:
yalign 0.95
xpos 0.01
xfill True
text("{color=#5f9ea0}Inv: %s{/color}" % inv)

Ah--I just had to enter

text("Inv: "+", ".join(inv))

at the bottom of the hbox definition.

Thanks again for the help... I wish there were an in-person training course for Renpy!
