Equipment System

I also think a simple inventory could be a good idea. Nothing fancy, just a small box, showing an icon for the currently selected pickup that can be activated, which can be scrolled with the mouse wheel or the dpad, without any added menus, windows or anything like that.

I understand if this is something we don't want, as it diverges from our core design (being a successor to Duck Game and all), but I still thought it was worth discussing.

As I am currently finishing up the items API, adding powerups (or Equipment, as they are currently named, in-code), this would be the perfect time to add this, if we want it.

Maybe this could be added as Mod example? I.e. the ‘Equipment mod’.

This will require scripting to be added, if we want to add it using the modding system I propose. Or it can be added by modding the source, of course.
The way the mod system I have planned works, is primarily by extending data and resources, by either replacing or extending the indexes that are defined in the various data files (items.json. textures.json, sounds.json etc), within the boundaries already put in place in-source. It can also be extended to work with scripts, if we add that, of course.

As this mod, if it was created, would modify the base behavior of items, in-game, it would probably become a dependency across the entire ecosystem, very fast.
If we want to add these features but limit their usage, I think it would be better to just implement it and not use it widely -- or at all -- for the core game items.

Internally, I will be creating an inventory of sorts, any ways (a vec of items currently picked up by the player), so that we can have effects from more than one of them active at a time. In other words, it won't be much work to just add the inputs to scroll those with active abilities, and to activate one, if we choose to do that. For the UI, we can just use the items sprites and display the currently selected one in a square box somewhere on the screen (one corner for each player, in couch mode, or bottom of the screen for network games)

Sounds relevant to the Item Extension System suggested in #151

This kind of stuff is why I abstracted the effects of items into passive and active effects. It should be very easy to add this, with the current API. Basically just a matter of creating a few structs, add serde tags and it should be ready to be placed into maps
