TypeError:object of type 'ATLTransform' has no len()[SOLVED]

[Luxliev]

I wanted to check code from renpy cookbook:
http://www.renpy.org/wiki/renpy/doc/coo ... y_movement

And I keep getting same error. What does this error message mean? Simple and complex form gives me same error.

Code used:

Code: Select all

init python:
    import math

    rho = 5.0
    mu = 15.0
    scale_factor = 1.0 - math.exp(-rho) * math.cos(mu)

    def springy_time_warp(x):
        return (1.0 - math.exp(-rho * x) * math.cos(mu * x)) / scale_factor

define e = Character('Eileen', color="#c8ffc8")

image eileen happy = "eileen happy.png"

# The game starts here.
label start:

    e "You've created a new Ren'Py game."

    show eileen happy at Move(offscreenleft, center, 1.0, time_warp = springy_time_warp)
    
    e "Once you add a story, pictures, and music, you can release it to the world!"

    return

Error message:

I'm sorry, but an uncaught exception occurred.

Maybe that code is obsolete?
you should use this documentation:
http://www.renpy.org/doc/html/

It's the one that's being updated^^

And I think it should be
show eileen happy at Move(offscreenleft, center, 1.0, time_warp = springy_time_warp())
with brackets behind springy_time_warp

[Luxliev]

Nope. That's probably not it. When I've added brackets it asked me for argument and when I added number in brackets it gave me again same error:
TypeError: object of type 'ATLTransform' has no len()

I tried to find more information on Move() but only found it in the old wiki documentation: http://www.renpy.org/wiki/Move
It states that it is deprecated and may not work properly with ATL. Since ATL statements are made with the keyword at, as here, it looks like there will always be a conflict. I would agree with mobychan and read through the new documentation instead.

[nyaatrap]

offscreenleft, center are Transform objects. I think they were Position objects when that's code is written.

[Luxliev]

So the best way to check this cookbook effect is to install older version of Ren'py if so which version I should be looking for?

[trooper6]

The wiki was outdated when I first started using Renpy...and that was 4 years ago.
You would be better off just making the transition with modern ATL.

[Luxliev]

Oh don't get me wrong I'm using ATL but I'm really curious how this will work and look like. That's why I'm asking for Ren'py version I should run this on. All Cookbook material is really interesting and useful so I just didn't want to left out any of the examples.

[nyaatrap]

Why not try simple tuple like (.5,.5) instead of center?

[Luxliev]

Unfortunately same error message. What's interesting this code is supposedly from Ren'Py 6.6.3 so not that long ago. I'll download appropriate version and see if it works.

[trooper6]

Ren'Py 6.6.3 is, I believe, from over 7 years ago...so a very long time ago indeed!

Anyhow, I got your code to work so:
show agentx angry at Move((-1.0, 1.0), (0.5, 1.0), 5.0, time_warp=springy_time_warp, xanchor="center", yanchor="bottom")

But...the bounces are horizontal, not vertical and they don't look great.
If you want a walking sort of bounce...I think it would be better to just go with saguaro's parallel code that moves a character vertically and horizontally at the same time.

[Luxliev]

Woah you're right I thought 6.6.3 wasn't so long ago. I implemented your solution and it works perfectly while simple form of this code doesn't look great as you noticed, its complex version is pretty good I really like easy ease animation it gives. For anyone interested I created Ren'py project with 6 examples and code ready to implement. It's basically actual Ren'py version of this Cookbook page:

Thanks for help!
