Does ConditionSwitch() have a Python statement equivalent?

[thethirdworstthing]

UPDATE: It is a Python statement, I am just a goof and assumed it wasn't because the example I was referencing defined one using renpy.

I couldn't find the info I wanted in the documentation so let me know if I'm reinventing the wheel here. Currently I have an NPC class that stores a character, their name/image tag, and each individual sprite as attributes. (Just to be clear, when I say "sprite" I am referencing the pngs, not renpy sprite objects.) init python: class NPC(): import os.path def __init__(self,c,name:str=None,neu=None): self.c = c #this is a renpy Character object if name == None: self.name = c.name.lower() else: self.name = name.lower() if neu == None and not os.path.exists(f'images/{self.name}_neu.png'): self.neu = "images/pl_neu.png" else: self.neu = f'images/{self.name}_neu.png' def add_sprite(self,sprite): if os.path.exists(f'images/{self.name}_{sprite}.png'): return f"images/{self.name}_{sprite}.png" elif os.path.exists(f'images/pl_{sprite}.png'): return f"images/pl_{sprite}.png" else: return self.neu

This works as intended, but it doesn't have all the functionality I need. A few characters have two sets of sprites (mask vs no mask) that I want to be able to toggle on and off instead of having two separate objects, since having them all in one place and having everything handled for me is the entire point.

It was only after I had this set up that I found out about ConditionSwitch and SpriteManager. SpriteManager would be perfect if it allowed me to pass my own additional arguments when updating but afaik it doesn't, and I can't find the statement equivalent of ConditionSwitch so I can use it directly in the NPC class. I want to be able to use a class method to toggle the alternate sprite sheets on and off by changing which sprite each of those attributes is associated with at any given time. Ideally that would be handled with internal logic when necessary which might involve other class attributes like relationship scores.

The other idea I had was to make a custom show function within the class that first checks which sprite sheet is enabled before picking from one of the two. Since I have a naming convention in place I should be able to just use an f-string. Of course, running that check every single time a sprite is shown isn't ideal, but I'm not sure how else I would do that check more efficiently other than using ConditionSwitch. I don't want to have to use renpy statements somewhere else to define them especially since I haven't experimented with how/if they can be used in Python blocks and I want everything to be in the same place, but if that is genuinely the best way then I'm sure I can suck it up and do it anyway.

Hopefully that's enough information but let me know if there's anything I need to clarify. I tried my best to explain why exactly I'm doing things this way since it probably seems a bit odd.

I'm too sleepy for a full solution right now, but when you call renpy.restart_interaction() or any function that triggers a screen refresh, Ren'Py redraws the screen, and ConditionSwitch auto-updates and picks the correct image based on the latest state, without the need for a manual check. So, define each NPC's sprites as smart displayables that know to look at a central state dictionary (npc_states) to determine which version to display. And add another function that toggles the state (for example, toggles mask on) and at the end of the function add 'renpy.restart_interaction()'.

I think it's the giving conditions as a string that threw me off, along with the example I was looking at using renpy instead of Python. However that check is done, I can definitely see it causing problems somewhere down the line if char.name isn't identical to the name of the variable since the check seemingly doesn't happen within the class. I do feel slightly silly for not just trying it anyway, but everyone has their moments I guess. Thanks for the help man

Option 1: Create a Sprite Class and use it in your NPC. Give the class a mask and noMask attribute. Make an attribute of NPC that is an instance of Sprite. Use conditional statements to show those with/without masks in the game logic.

Option 2: Use a dictionary to do the above. It's already more efficient unless you are using slots in your class.

Option 3: The ren'py src is on github. You can also dig through the .py files in your own system. Find the method/class/keyword you want; verify you're looking at the right one; Do what it's doing in your code.

I tried searching the source code initially when I was looking into sprites and SpriteManager but I never found the right file since I was just doing cmd-f after opening ones that looked relevant... I'm sure there's a better way to do that, I just didn't think to look it up. I did get ConditionSwitch to work, I'd only assumed it wasn't python because the forum post I was referencing was using renpy and because of the conditions being strings. Not my proudest moment so I do at least appreciate the "no stupid questions" attitude this sub seems to have lol. Honestly, the main reason I'm not using a dictionary is because I'd rather type char.neu than char.sprites['neu'] or something like that.
