[SOLVED] Python statement equivalents

I'm having difficulty getting my head around some the proper python statement equivalents. I want the python equivalents in order to avoid a 100-branch ifelse tree.
Code: Select all
init:
image image1="someimage"
image image2="otherimage"
$ image_array=["image1","image2"]
transform pos1:
xalign=0.2 yalign=0.5
transform pos2:
xalign=0.8 yalign=0.5
$ pos_array=["pos1","pos2"]
elsewhere:
python:
rand=renpy.random.randint(0,1)
renpy.show(image_array[rand],pos_array[rand])
renpy.hide(image_array[rand])
(The actual use-case is considerably more complicated)
It seems that the renpy.hide() statement works fine, so it appears that referring to images that way works, but it doesn't seem to work for the transform. Also, I'm not sure how I would go about showing an image with a transition programmatically. There's clearly something I'm missing about how to handle renpy actions from within a python block.
Thanks in advance.

You can do something along these lines (totally untested) but you can just forgo declaring the images with Ren'Py and plainly randomly draw from a list of paths. I always do...
Code: Select all
$ images = []
for n, i in enumerate(["paths to images"]):
tag = "image" + str(n)
renpy.image(tag, i)
images.append(tag)
ATL Functions can be just thrown and a list and renpy.random.choice() from that list same as with images, just don't call them (aka just the names without brackets).

Well, the random part isn't actually relevant; what I'm having trouble with is duplicating:
Code: Select all
show someimage at sometransform with sometransition
in a python block, as I don't think renpy statements support lists (or, at last, I can't find a way to define such lists in a renpy-friendly manner).

I thought they did... in any case:
renpy.show(tag, what=displayable, at_list=[Transforms or atl funcitons])

Okay, so to do that:
How can I get a Transform object (which is what the at_list is expecting, based on the error message) when the Transform is defined in a renpy statement?
or
How can I define a Transform object in a python block? It looks like a Transform object is specific to a child displayable, so would have to be initialised afresh whenever called on a different image, making a different beast entirely to a renpy-defined transform.

I am not sure that I follow...
These are some examples from my project:
Code: Select all
$ renpy.show("_tag", what=Text("%d" % wage, style="back_serpent", color=gold, size=40, bold=True), at_list=[found_cash(150, 600, 2)])
Ren'Py statement would be:
Code: Select all
show expression Text("%d" % wage, style="back_serpent", color=gold, size=40, bold=True) at found_cash(150, 600, 2) as _tag
which I prolly should have used here.
Here is one deep within Python showing both, a Transform and an ATL Function with instructions:
Code: Select all
for index, target in enumerate(targets):
aimpos = battle.get_cp(target, type="center")
renpy.show("launch" + str(index), what=missle, at_list=[move_from_to_pos_with_easeout(start_pos=initpos, end_pos=aimpos, t=pause), Transform(anchor=(0.5, 0.5))], zorder=target.besk["zorder"]+50)
Code: Select all
python:
n = Character(" ")
img = get_random_event_image("simple_beach")
renpy.show("event", what=img, at_list=[center])
renpy.with_statement(dissolve)
And the function (
not safe for android, renpy.list_files should be used instead) (content path is just a func returning os path leading to game/content folder) (ProportionalScale is a class returning resized image no properly scaled to take the largest of two sides and scale the other one preserving the true image ratio):
Code: Select all
init -9 python:
def get_random_event_image(eventfolder):
templist = []
if eventfolder in os.listdir(content_path('events')):
for file in os.listdir(content_path('events/%s' % eventfolder)):
templist.append('content/events/%s/%s' % (eventfolder, file))
return ProportionalScale(choice(templist), config.screen_width, config.screen_height)

Ok, many thanks, I think I've got a better handle on what's going on. With some significant experimentation, I've got it behaving. I think my problem was how renpy.show parses the arguments; the image you use can be given as a string that names a renpy image object, but you can't do the same thing for the transform, plus some confusion I had about the difference between the 'name' and 'what' arguments which I think I've got straightened out now.
Cheers!
