[solved] how to pass additional arguments to bar's changed function

[Kia]

I have this bar:

Code: Select all

                bar:
                    xysize 300,40
                    value i[1] range i[2] changed g.changed

how can I pass additional arguments to the changed function?

How about using Bar Values?
https://www.renpy.org/doc/html/screen_a ... bar-values

Otherwise, if a function doesn't accept enough arguments, I would pass them through global variables.

If understand you correctly, you can use Function action: value i[1] range i[2] changed Function(g.changed, arg1, arg2, key=value)
Or you can use renpy.curry, if you want to.

I did look into that, but couldn't fund any substantial information or an example for it. even tried FieldValue() to no avail

setting up global variables isn't feasible in my case, too many variables to declare.

I've already tried that, it gave me:

Code: Select all

    store._return = renpy.call_screen(name, *args, **kwargs)
TypeError: __call__() takes exactly 1 argument (2 given)

the function already passes the bar value to the function as an argument, I just have to figure out how to append one more to the *args

[Ocelot]

you can try changed renpy.partial(g.changed, arg1)
partial returns a callable which, when invoked, calls other callable, passed as first argument, with combination of arguments passed during partial creation and during final call.

As the documentation says, we can subclass BarValues. Searching Github (renpy/renpy) I found

https://github.com/renpy/renpy/blob/8aa ... values.rpy

which shows how FieldValue etc. work.

renpy.partial did the job, thank you Ocelot. I'm sure it will come handy in all kind of situations.
and thank you jeffster
