properties statement in style

[felsenstern]

Hiya,

can someone please help me out explaining the following 3 lines to me?

style default:
properties gui.text_properties()
.
.
properties gui.text_properties("input", accent=True)

1. style default: where is it used (windows, frames ... and so on)? Does it need to be defined again somewhere or is it really a default value?

2. properties command: what is it doing what transfer parameter is it expecting (or where in the docs is it explained).

3. gui.text_properties(): what is it returning and where and how is this defined? It looks like a class property but then wouldn't empty round brackets after the call not cause an error? And then again I couldn't find it being defined somewhere in my rpy-files.

4. gui.text_properties("input", accent=True): what is this returning and why?

P.S.: I've read through the Style and the Style Properties Documentation a couple of times but without understanding the 3 lines above. And please, I know that I'm a noob and I really pondered over this for more than two weeks instead of continuing writing my game just to avoid asking this here.

1. it is the base style for all styles iirc. renpy creates that.
2. https://www.renpy.org/dev-doc/html/scre ... statements. it accepts a dict of styles you want to pass.

Code: Select all

style mystyle:
  properties dict(xsize=1.0, align=(0.5, 0.5))

is also the same as...

Code: Select all

style mystyle:
  properties {} # empty dict
  xsize 1.0
  align (0.5, 0.5)

3. https://www.renpy.org/doc/html/gui_adva ... properties. it's a function, not a class property. the kind parameter for that function is also found in the docs: https://www.renpy.org/doc/html/gui.html#text.
4. again, these functions return a dict of style properties.

First of all, thanks for answering, and thanks for the links. Allow me a few follow up questions.

1. dict is a kind of list in which entries can only exist one time?

2. if accent is not in the function parameters, then it's False?

1. Dict is some sort of basic data type in python aside from other objects such as list, tuples, int, etc. So you should learn more about it. Its a python thing so you can learn this from python courses.
Basically, imagine it as a list wherein instead of numbers as indices, you can use different objects as index.

Code: Select all

default a = [0]
default b = {"zero": 0, 1: 1} # equal to b = dict(zero=0), you cant do 1=1 in this kind of format so you can resort in the traditional way.

label start:
  $ print(a[0]) # with lists you are limited to int as index in accesing the element.
  $ print(b["zero"], b[1]) # with dicts you can use almost any object as index/key in accessing the element.

And of course each data type has their own pros and cons. Dicts are unordered while lists are ordered.
2. Depends if the parameter is optional. Still this is a python thing so you can learn this through python courses.

Code: Select all

init python:
  def fun(a, b=1): print(a, b)
  fun(10) # b is optional and defaults to 1
  fun(10, 5) # b is given a value of 5 instead of its default

Well, thanks a lot. This helped a lot.

And I bought a bundle full with python coding books a few months ago, but I just recently learned init python and that you can write python code inside renpy. So I will give it another try...
