[Proposal] Replicate the interact area's strategy for things that can be attacked

[JuanFdS]

Right now, the only entity that can be attacked are projectiles. This is constrained both by code and by the collision mask of the PlayerFighting/HitBox in player.tscn:

threadbare/scenes/game_elements/characters/player/components/player_fighting.gd

Lines 37 to 38 in 5a51c49

	func _on_air_stream_body_entered(body: Projectile) -> void:
	body.got_hit(owner)

I think a good strategy could be to do the same thing we are doing with the InteractZone + InteractArea:

• Have a HitBox + HurtBox. HitBox used by player attacks and HurtBox being an area that emits a signal when activated by a HitBox. Projectiles could be reimplemented using something like that.

This has a limitation as proposed: it is only possible to be applied to player attacks that hit everything that is attackable. It doesn't attempt to handle other things that could also attack (like enemies or projectiles).

Yes indeed, we need to discuss how to design the game entities from now on to support more mechanics. Other ideas:

• Decouple the "can walk" behavior from the guards, so other entities like NPCs can walk around.
• Same as above for the "can catch you" behavior.
• Instead of having a Talker subclass of NPC, have a "can talk" behavior.

In general, I think this means using composition over inheritence, and coming up with a good design pattern that isn't too magical.

@JuanFdS see #774 for an exploration we are doing.
