Hello, again. I'm really newbie here. So... I saw in documentation this command: renpy.exists(filename). Can you give me an example?

Code: Select all

renpy.exists(name_here.txt)
if true:
secret_route_unlocked = true
if false:
pass

Well, something like that. Thanks for help.

Just my two cents:

Add a 'name_here.txt' file to your '/game/' folder (where 'script.rpy' resides).

Code: Select all

init python:
    ## set-up objects
    secret_route_unlocked = False    

image bg = Solid('#000') ## create black background image
    
label start:
    scene bg ## show background
    
    python:
        ## test if the file path exists, setting the 'secret_route_unlocked' object if file exists
        if renpy.exists('name_here.txt'):
            secret_route_unlocked = True

    ## display result
    "Secret route unlocked: [secret_route_unlocked]"

    # game ends here
    return

Thanks! It's helped. But, if you can, say, how to write "else" to this command. When I write it, it just skipped, i guess. Or I must write if secret_route_unlocked = true etc?

Code: Select all

image bg = Solid('#000')
    
label start:
    scene bg
    
    python:
        ## test if the file path exists, setting the 'secret_route_unlocked' object if file exists
        if renpy.exists('name_here.txt'):
            secret_route_unlocked = True
        else:
            secret_route_unlocked = False

    ## display result
    if secret_route_unlocked == True:
        "The Secret Route is now unlocked ..."
    else:
        "No Secret Route for you ..."

    # game ends here
    return

That will test for True or False.

To test for multiple conditions:

Code: Select all

python:
    a = 32
    
    if a == 32:
        print "32"
    elif a == 12:
        print "12"
    else:
        print "'a' doesn't match any expected values!"

Watch out for '=' vs '=='.

'=' will assign a value to an object; whereas '==' tests for equality.

Okay, thanks

Just want to mention this feature is unsupported on mobile devices. It will work fine on PC though.

Current documentation says "You almost certainly want to use renpy.loadable() in preference to this function."
