Little idea what I am doing (ATL) [Solved!]

[10kNing]

What I'm aiming for is an animated heart thingamabobber that moves more quickly as the variable "heartbeat" increases:

Code: Select all

    image heart:
        "heart/heart1.png"
        pause ((20 - heartbeat)/20)
        "heart/heart2.png"
        pause ((20 - heartbeat)/20)
        "heart/heart3.png"
        pause ((20 - heartbeat)/20)
        "heart/heart4.png"
        pause ((20 - heartbeat)/20)
        "heart/heart5.png"
        pause ((20 - heartbeat)/20)
        "heart/heart6.png"
        pause ((20 - heartbeat)/20)
        "heart/heart7.png"
        pause ((20 - heartbeat)/20)
        "heart/heart8.png"
        pause ((20 - heartbeat)/20)
        "heart/heart9.png"
        pause ((20 - heartbeat)/20)
        "heart/heart10.png"
        pause ((20 - heartbeat)/20)
        "heart/heart11.png"
        pause ((20 - heartbeat)/20)
        "heart/heart12.png"
        pause ((20 - heartbeat)/20)
        "heart/heart11.png"
        pause ((20 - heartbeat)/20)
        "heart/heart10.png"
        pause ((20 - heartbeat)/20)
        "heart/heart9.png"
        pause ((20 - heartbeat)/20)
        "heart/heart8.png"
        pause ((20 - heartbeat)/20)
        "heart/heart7.png"
        pause ((20 - heartbeat)/20)
        "heart/heart6.png"
        pause ((20 - heartbeat)/20)
        "heart/heart5.png"
        pause ((20 - heartbeat)/20)
        "heart/heart4.png"
        pause ((20 - heartbeat)/20)
        "heart/heart3.png"
        pause ((20 - heartbeat)/20)
        "heart/heart2.png"
        pause ((20 - heartbeat)/20)
        "heart/heart1.png"
        pause ((20 - heartbeat)/20)
        repeat

...

    $ heartbeat = 1
    show heart
    "Test line"

But this error popped up:

I'm sorry, but an uncaught exception occurred.

ZeroDivisionError: float division

and I have no idea what that means since as far as I can tell I haven't divided by zero... I don't completely understand ATL yet, so could someone help me learn what's wrong with the code? Thank you.

Ok, not really a pro here, so just wild guessing, but several thoughts:

1. try setting heartbeat to a number (i.e., defining the variable) before initiating the images
2. try to make ((20 - heartbeat)/20) a function that is then used there

What exactly are lines 144 and 311 in script.rpy?

[10kNing]

1. Already set heartbeat to a number ($ heartbeat = 1). It's supposed to be an integer between 0 and 20. The error still pops up even when the number is valid, thoughhhh

2. Made a function:

Code: Select all

        def findbeat(beat):
            return ( 20-beat )/20

...

    image heart:
        "heart/heart1.png"
        pause findbeat(heartbeat)
etc.

but the error still pops up, sadly.

Lines 143-145:

Code: Select all

        "heart/heart2.png"
        pause findbeat(heartbeat)
        "heart/heart1.png"

Line 311:
$ heartbeat = 1

[Milkymalk]

Stupid question, but did those lines have these line numbers before you added the function?

What's interesting is that the error seems to come up towards the end of the ATL block...

Sorry, that was all I could think of. I don't see any division by zero either.

[10kNing]

Oh right -slightly dumb- The new line errors are at 313 ("Test line") and 146 (pause findbeat(heartbeat) between the last "heart1.png" and "repeat"). Huh... Well, thanks for trying to help, at least~!

[Alex]

Try

Code: Select all

$ heartbeat = 1.00

(19/20 = 0, but 19.00/20.00 = 0.95)

[10kNing]

It worked!! Thank you! ^^

[Milkymalk]

Try

Code: Select all

$ heartbeat = 1.00

(19/20 = 0, but 19.00/20.00 = 0.95)

I thought to get integer division, you had to use "//" instead of "/"?

I thought to get integer division, you had to use "//" instead of "/"?

That's Python 3. Ren'Py uses Python 2 for the time being.
