NameError: name 'zoom' is not defined

[Dsiak]

Hello, I'm having a strange problem where Python will not accept my attemp at passing a property as a parameter, it goes as follow:

Code: Select all

Line 67:
    show bg dream at daughter_crop
    with dissolve
Line 29:
    transform daughter_crop:
    linear .75 subpixel True xpos 0.0 ypos 0.0 xanchor 0.0 yanchor 0.0 zoom 2.58 rotate None
    parallel:
        breath(zoom)
        repeat

transform breath(zoom_value, zoom_offset = 0.1, zoom_time = 5.0):
    linear zoom_time zoom zoom_value - zoom_offset
    linear zoom_time zoom zoom_value

Even though zoom appears as it is set in-game, and the function works if I send a 'float' instead of 'zoom', the trace back tells me that zoom is not defined, traceback bellow:

Code: Select all

I'm sorry, but an uncaught exception occurred.

Off course I could just send the 2.58 instead, but this will be cumbersome when I have to make a change and when I use in other situations. I wanted to know how come I can not get the value stored in 'zoom' like this and what would be the correct way to go about it.

[Donmai]

Isn't "zoom" a reserved name? Have you tried "my_zoom", or something else?
https://www.renpy.org/doc/html/reserved ... rved-names

[xavimat]

Inside the "transform daughter_crop" you don't have a variable named "zoom", so renpy can't understand the line "breath(zoom)". Another problem is, as Donmai has pointed out, that you shouldn't use "zoom" as a variable name.
The long line where you define "zoom 2.58" does not mean that renpy has a variable "zoom" that now is equal to 2.58, that's a property, not a variable.

On the other hand, you could shorten this:
xpos 0.0 ypos 0.0 xanchor 0.0 yanchor 0.0
to this:
align (0.0, 0.0)

I was under the impression the property should return me a float because of this part in the atl documentation.

I'm still a little bit confused, I see that the zoom is not a variable (as I though it was) but is there a way I could check the value of this property to store it in a variable of mine? (something like $ my_zoom = zoom)

Code: Select all

linear start subpixel True align (0.0, 0.0) zoom 2.6 rotate None
    $ my_zoom = zoom
    parallel:
        breath(my_zoom)
        repeat

did not work, but I'm just guessing at this point.

Code: Select all

File "game/dream.rpy", line 28: expected 'comma or end of line' not found.
    $ my_zoom = zoom
