There's not much to see, really. The monsters are added through a slightly complicated chain of events as children of the dungeon, which inherits from TileMap. So, when I want to check a particular grid location I do

func map_unit(pos:Vector2):
	for c in get_monsters():
		if c.grid_position == pos:
			return c

func get_monsters():
	var out = []
	for c in get_children():
		if c.get('is_creature'):
			out.append(c)
	return out

That's a simplified version.

The advantage for me is that I don't have to maintain the objects in two places. They're always going to be part of the scene tree, so if I use another structure to track them, I'm duplicating effort, and creating the possibility of the two getting out of sync (which actually happened when I was doing it that way).

Note that I'm checking for an "is_creature" property instead of using "is Creature" to check the object type. That's just because gdscript 1.x still has huge issues with cyclic references. In a project with a lot of code, it becomes impossible to use typed variables with custom class names or even to use the "is" keyword without errors.

I just offer that as an alternative. There are lots of ways to do it.

    Since there are only tiles, tokens and cards in the game but all the player's actions will be on the cards, I guess I'd better use already existing card games resources.
    But apparently there are many different ones, at least two : the Card Game Framework by dbo and the Card Engine by Braindead.

    Which one is best to use ?
    I really need only simple things :
    1 - A list of different cards
    2 - A few decks to draw from
    3 - Animation to show the cards in each deck when one wants to draw (it's not random drawing in my game, the player chooses the card he wants - so I guess functionally it's more a "hand" than a "deck" but UI wise they'll be shown as decks on the board)
    4 - Ability (and the corresponding animation I guess) to choose a card and play it on the board (on BoardPlacementSlots I guess).
    5 - Ability for BoardPlacementSlots to hold (and show) many cards on it
    6 - Ability (and the corresponding animation) to check which cards are on BoardPlacementSlot

    And that's it.

    I dabbled a little bit with one of them (dbo's I guess) before I changed computer and had to re-download everything (which led me to understand that there are more than one) and apparently the way to use it was to open it with Godot and then add my scenes inside of it ?
    Isn't it a bit heavy and cumbersome ?
    Do both framework (or others I don't know of) work that way ?

    I'm much prefer have clear snippets of code/ressources that I could import into my project and then modify according to what I need.

    Well, I tried BrainDeadBzh's framework CardEngine and looked a bit at its documentation.

    But it says "To create a database press the "Create new database" button."
    Where do I find this button ?
    There's a screenshot of the button but on a panel I don't know where to look for.

    Or is the addon just not working ?
    I got "Impossible de charger le script de l’extension depuis le chemin : « res://addons/cardengine/card_engine.gd ». Cela peut être dû à une erreur de programmation dans ce script.
    L'extension « res://addons/cardengine/plugin.cfg » a été désactivée pour prévenir de nouvelles erreures." when trying to enable it in the Project Settings/extensions panel.

    I did try CardEngine in different versions of Godot but to no avail, I still get the same error message.

    I also tried a different add-on to test whether I was doing something wrong, but this other add-on works.

    The error message seems simple enough, but I don't understand why it appears : I checked that there is actually a card_engine.gd file in addons/cardengine and its syntax doesn't seem different than any other plugin's.
    It's also, as far as i can see, correctly referred to in the plugin.cfg file.

    It would probably be more helpful if you could provide the error in english.

    as per github repo :

    Currently under development, do not expect it to work.

    Everything is work in progress.

    You can maybe open an issue on the repo tho. @braindeadbzh seems to be registered on the forums so perhaps they can confirm if this is the preferred way to move forward.

      LienRag How ?
      Godot gives it to me in French...

      I mean you could translate it, either yourself or using a translation app or such. As the one requesting help I'd say the onus is on you to make helping you as low barrier as possible. This is not limited to just translating errors given but also including things such as providing more info about how the relevant scene is built, what the node structure is like, what signals might be connected and to where, etc.

          LienRag Is there a non-microsoft repository

          Microsoft doesn't own the contents of the repo tho, they only acquired the service provider. It's one thing if you don't want to host any of your code there but reporting issues to the relevant repo shouldn't really be an issue realistically.

              Megalomaniak

              Oh, OK.
              "Impossible to charge extension's script from path : « res://addons/cardengine/card_engine.gd ».
              This may be due to a programming error in the script.
              The extension « res://addons/cardengine/plugin.cfg » has been disactivated to prevent further errors".

              No relevant scene is built since I get this error whether I try to activate the plugin in an already existing scene or on a completely brand-new one.

              This from 3.3 to 3.5.0.

              Well, this requires an account in the devil's book, doesn't it ?
              I do have one from before they were acquired (though they weren't free software at that time either) so I probably can soil my soul the way you recommend it, yes.

                  12 days later

                  Apparently the plugin works and I just don't understand how to use it.
                  Problem is, I still don't understand.
                  "this repo is supposed to be used as a template" : how to do that ?

                  If you think you have all the files in place in your project directory, you might be missing the necessary AutoLoads that need to be present before activating the plugin.

                  You also need the project.cardengine file at the root of the project which contains folder paths that should exists.

                  Well, lets go through it in order: Have you set up the appropriate autoloads as shown in the image?

                  Do you have the project.cardengine file in your project root? You might have to poke @braindeadbzh about providing an example project.cardengine file perhaps if there is no documented example of what paths it should hold.

                  The project.cardengine file from the repo can be use as it is, most of the projects won't need to change the content.

                  I never really took the time to describe how to install CardEngine into an existing project, the idea being to create your project from the demo. But a simple way could be (NOT TESTED - BACKUP YOUR PROJECT BEFORE):

                  1. Past the whole repo content into your project (except git files)
                  2. DO NOT overwrite existing files
                  3. Add the Autoloads

                    braindeadbzh Past the whole repo content into your project

                    Well, I chose CardEngine over CardGameFramework specifically to prevent having to do that (it makes the learning curve way steeper)... but I guess what has to be done has to be done.

                    braindeadbzh Add the Autoloads

                    There were four autoloads automatically activated. I guess that I should keep them that way ?

                    Now I'm a bit at a loss : if I "do not overwrite existing files" how do I start my game rather than the demo ?

                    braindeadbzh the idea being to create your project from the demo

                    How to do that then ?

                            I tried (in Godot 3.5) db0's Card Game Framework since it has a "quickstart" documentation (on the EEE site alas) and I vaguely understand what it's telling me to do, but I'm stuck at the 2.1.6 step : I'm told to load my new inherited thingies under "Script variables" in the inspector but there is no "Script variables" in the inspector ?
                            How am I to make it appear ? I'm seeing the inspector of the new inherited main scene, am I doing this wrong ?

                            LienRag There were four autoloads automatically activated. I guess that I should keep them that way ?

                            Only the ones that point to a script in addons/cardengine are necessary the other are only there to support the demo.

                            LienRag Now I'm a bit at a loss : if I "do not overwrite existing files" how do I start my game rather than the demo ?

                            If you did not overwrite any file when pasting CardEngine into your project this should not have changed the main scene.

                            LienRag How to do that then ?

                            If you start from the demo, then you can follow the documentation

                                  I'm surprised to not have written it anywhere I can find it, but what blocked me two years ago and up to now is not only that I didn't understand at all how to use one of the Card frameworks, but also that when designing the checkerboard I wasn't able to find the lift.

                                  I have no idea how to make the screen responsive and for a mock-up I won't care to try, so I just put the tiles at the size they seem to fit best in my eyes.
                                  But that means that there are too many tiles to fit on my screen, so I need a vertical and horizontal lift to navigate the full checkerboard, and I was completely unable to find how to do that.
