Ren'Py Call screen with random picture.[SOLVED]

[Deleted member 416612]

Hi mates,

I am trying to add a screen that will show a random picture from a series. For example in free-roaming, when a user will navigate to a location, then a random picture will be shown and if the same user will navigate again to that screen, another random picture is shown, from the same series.

Can anyone help me with a hint?

Cheers

You can use "renpy.random.choice(seq) => Return a random element from the non-empty sequence seq".

randPicture = renpy.random.choice(['pic1.png', 'pic2.jpg', 'mypic.gif'])

Than, just use the variable randPicture to display the random picture.

Like Brasdf said, the first part of the answer is in renpy.random.choice. It will choice randomly one of the entry in the list you pass as parameter.

Then, the second part of the answer is in the default screen statement. It assign a value to a screen variable, but will not update it when the screen will be refreshed. This let you define randomly the background, and keep it consistent until the screen is hidden/replaced. Then when you'll show/call it again, a new image will be selected for the background.

# List of the possible background for the location "here"
define hereRndImage = [ "image1.jpg", "image2.jpg", "image3.jpg" ]
# same for the location "there"
define thereRndImage = [ "image4.jpg", "image5.jpg", "image6.jpg" ]

# screen for the location "here"
screen locationHere():

    default bground = renpy.random.choice( hereRndImage )

    add bground
    [...]

Obviously, there's a lot of possible variations around that.

Thank you, mates! Now that I am back to the PC, I will try it.

Hey mates,
I finished the tests and with your examples and everything worked perfectly.
Thank you a lot for your help.

Riddle me this:
I added this to renpy and it gave me this error:

PARSING THE SCRIPT FAILED
file "game/script.rpy, line 76: expected statement
randPicture -> = renpy.random.choice(['image.01.jpg', 'image02.jpg', 'image03.jpg'])
whereas the -> above is a red arrow.

Why am I getting an expected statement error when I'm using a renpy.random.choice which should be built in?

Probably have to put a dollar sign in front to tag it as Python
