How to "hover "images/[items[i]].png""?

[kafkaontheshore]

Hey there!

Code: Select all

    ## Items ####################
    hbox xpos 40 ypos 1113 spacing 25:
      for i in range(len(items)):
        imagebutton: 
            action If(len(items)>=i, Jump('test'))
            idle "images/[items[i]].png"
            hover "images/[items[i]].png"
            insensitive "inventory insensitive.png"
            hovered Notify(items[i])
            unhovered Hide("notify")

results in:

Code: Select all

While running game code:
  File "game/script.rpy", line 25, in script
    call screen body
  File "renpy/common/000statements.rpy", line 609, in execute_call_screen
    store._return = renpy.call_screen(name, *args, **kwargs)
Exception: In DynamicImage 'images/[items[[i]]].png': TypeError('list indices must be integers or slices, not str')

It works if do this instead: hover "images/[items[0]].png". But that would result in a lot of probably unnecessarally repetitive work. How to generalize the numbers?

Thanks for your time.

for i in range(len(container)): container is an antipattern. If you do that, it is almost certainly wrong. Iterate on elements instead. You can have python statements inside your loop to prebuild paths, extract data from containers, etc. and not rely on interpolation and such.

Code: Select all

for item in items:
    $ imagepath = "images/" + item
    imagebutton:
        action Jump('test') # your condition is always true anyway
        idle imagepath # no need to hover, since it is the same as idle
        insensitive "inventory insensitive.png"
        # do not use hovered/unhovered pair for something better done with tooltip.

If you do need index for something, you can use enumerate and tuple unpacking:

Code: Select all

for i, item in enumerate(items):
    text str(i) + "th element: " + item
