Did you install the Steam support from the Ren'Py launcher? That's required for any Steam integration. Remember also that you'll have to go through Steam to clear any achievements if you'd like to re-see the popup, as the clear method only clears it on Ren'Py's end. You can install the Steam support via the launcher Preferences -> Install Libraries -> Install Steam Support. The overlay isn't related to whether Steam support is installed or not, just if you're playing it through Steam. Let me know if that fixes it for you!

Sure thing! You can remove the achievement gallery screen or just not use it anywhere. The popups will work just fine. 

Same thing goes in reverse, too - you can use the config options at the top of the file to remove popups and just use the gallery if you like.  

Sure! You can change the text colour of any of the screens however you like by adjusting the styles; all of the existing styling is meant to be changed to suit your project. I suggest you hover over the text in question and hit shift+i to find which styles are affecting it, or you can find the lines in achievements.rpy and just add color "#fff" or similar to whichever line of text you need. For example, you can change the line text a.description size 25 to text a.description size 25 color "#fff" to make the text white. Hope that helps!

Yes, time is a reserved name that refers to the Python library time. Call the variable something else and it should work.

It's not a requirement or anything! That's just an example of a button you can make so players can see your achievement gallery. In a standard Ren'Py project, that would go on screen navigation in the same pattern as all the other buttons there. But you can create whatever kind of button or method to access the achievement gallery that you want.

You're meant to change the sound with your own define statement, not in the backend file! For example,

define myconfig.ACHIEVEMENT_SOUND = "audio/interface/ach.ogg"

The achievements.rpy file has examples of that. If you're only changing it in the backend, then the redeclaration in achievements.rpy will be overwriting it with None. The backend file has an early initialization order so it can be set up early before it's used and modified with a regular define statement.

So, in short, change it in achievements.rpy not in the backend file :) Hope that helps!

Hello! That option is only available to developers during development for testing, so if you make a build then players can't toggle achievements. To remove it altogether you can look for the action under a `if config.developer:` block and get rid of it.

Hello! You have to make a button to lead to the achievement gallery yourself - it's not built into your project or the tool because I don't know how your main menu screen is set up. That's what this bit of code in the instructions is for:

textbutton _("Achievements") action ShowMenu("achievement_gallery")  

You need to add that or something similar to your project to access the achievement gallery. Don't delete datetime either - that was a very specific case where another bit of code had imported datetime already in a different way. I suggest not changing anything in the backend unless you understand what you're doing.

Can you share any code you've tried?

If you want to check if the player is skipping a specific section of dialogue, you can check for if renpy.is_skipping(): (https://www.renpy.org/doc/html/other.html#renpy.is_skipping) at the start of that dialogue, and if it's true, grant your achievement. Otherwise, you can also add an achievement action to the Skip button on the quick menu (e.g. action [skip_achievement.Grant(), Skip()] on the quick menu button). The latter suggestion will *not* cover the case if the player uses a keyboard key like CTRL or Tab to start skipping; the best way to handle that more general case would be through a callback https://www.renpy.org/doc/html/config.html#var-config.interact_callbacks. If you're new to coding, I would wait to implement the last option until you're a bit more comfortable with Python! I hope that helps :)

Sure! The achievement itself is passed into the popup screen (by default, as the argument called "a"), so you can check for that and use a different background e.g. 

frame:
    style_prefix 'achieve_popup'
    if a is all_achievements:
        background Frame("my_platinum_frame.png", 5, 5)

So, when you say nothing happens - does it not grant the achievement at all, or are you just not seeing the popup? You can watch the status of the achievement by bringing up the console with shift+o and typing watch ACHex.has() for example. If you already have the achievement, it won't re-grant it. If proceeding past that line in your script does not change the achievement to being unlocked, then that's a different issue from it changing it and you not seeing the popup screen. If you're testing on Steam, you may need to clear the achievements from their backend as well. See the bottom of this article: https://partner.steamgames.com/doc/features/achievements/ach_guide

You need to create a persistent set, e.g.

default persistent.seen_endings = set()

and then you will add to that set when you reach a relevant part in the game (that's this part:)

$ persistent.seen_endings.add("end1")

and in order to record that progress for an achievement, you can set the progress to the length of the list e.g.

$ ending_achievement.progress(len(persistent.seen_endings))

Sets are used because they can't have duplicates, so the length of the list will be the number of unique endings the player has seen, and it won't matter if they go through the same ending multiple times/it won't count them more than once towards the achievement.
