Beginner questions

[LittlJack]

Hello there

Since I am a softwaredeveloper I want to get quick into the RenPy script language.
I took a quick look at the docu and saw that it is a beginner documentation so maybe I can get into it quicker with some advanced questions the I could not answer myself.

1. Is it possible to create a OOP structure?
2. Is it possible to split code into multiple files?
3. How do I call functions with parameters, for example this crashes the game:

Code: Select all

... in screens.py
screen main_character_stats(money):
    frame:
        xalign 0.01 ypos 40
        text _("Money : XXX")
        
        
        ... in script.py
        $ money = 200
        show screen main_character_stats(money)

4. Is it possible to have multiple characters on the screen?
5. How can I make a status lable like the money lable or similiar visible persistent?
6. Is there a way to store a game state with variable data like money in a simple way or do I have to write an own serializer and store it to a json or similiar?

I guess that is the most important for beginning.
Thanks for your help.

1. you can include python code inside renpy. To define classes you can use an "init python" block. https://renpy.org/doc/html/python.html# ... -statement

2. Yes. viewtopic.php?f=4&t=53442&p=503389&hili ... es#p503306

3. It seems that code should work, if it crashes, the error must be elsewhere. I guess you are mixing label-code and screen-code. (Better if you define the money variable first with "default". https://renpy.org/doc/html/python.html# ... -statement )

4. You don't have "characters" on screen but displayables. You can use "show" to show different pictures. Renpy does not know if the picture itself represents a character or an avocado. You can use "scene" to clear the screen of images "showed" and present a new one. That's the reason "scene" is used mostly to show backgrounds (like a change of scene in a film).

5. There are two languages inside renpy (well, more than two), label language is different from screen language. There is not a "status label", but you can show a screen with that information.

6. I'm not sure if you are talking about the save/load system that renpy has out of the box. https://renpy.org/doc/html/save_load_rollback.html
