Ive been on this for a week and a half and its one of the only things holding me back. Ive followed multiple tutorials, but none of them seem to work at all.
I have an interactable instance, but i need a way to be able to put that in an inventory. Problem is, I have no idea how to make that work. Ive attempted both without and with tutorials, and its genuinely giving me headaches :,D (The interactable code will be at the bottom)
im pretty new to godot, i can only make simple code by myself/kinda know how and why each node works together, so some solutions ive seen seem like a foriegn language haha.
TLDR: How to make an inventory? Like, a working one? (Please explain like im five :,D)
INteractable instance:
extends Node3D
var current_interactions := []
var can_interact := true
func _input(event: InputEvent) -> void:
if event.is_action_pressed("interact") and can_interact:
if current_interactions:
can_interact = false
await current_interactions[0].interact.call()
can_interact = true
func _process(_delta: float) -> void:
if current_interactions and can_interact:
current_interactions.sort_custom(_sort_by_nearest)
func _sort_by_nearest(area1, area2):
var area1_dist = global_position.distance_to(area1.global_position)
var area2_dist = global_position.distance_to(area2.global_position)
return area1_dist < area2_dist
func _on_area_3d_area_entered(area: Area3D) -> void:
current_interactions.push_back(area)
func _on_area_3d_area_exited(area: Area3D) -> void:
current_interactions.erase(area)
INteractable script (each interactable object is on the same layer and within a class if that helps):
Create an area node. 2d or 3d depending on your needs. Create an export var. Drag the scene into the export. Now, it will be stored within the scene as a compressed scene.
When a body enters the area - check if it is named player, in group players or whatever you do to decide if its the player that has entered or not.
If player: instantiate the variable and append it to body.inventory
So the first question is “Where is your inventory relative to this interactable?” How do you give control of the inventory all the way to this interact() function; it seems like your “Interactable Instance” may be related to the player quite directly, if it is a child of the player scene then you can access the player through a @export variable, then pass the player into your interact calls.
extends Node3D
@export var player: Player ## new line
var current_interactions := []
var can_interact := true
func _input(event: InputEvent) -> void:
if event.is_action_pressed("interact") and can_interact:
if current_interactions:
can_interact = false
await current_interactions[0].interact.call(player) ## added `player`
can_interact = true
Your intractable objects must take a player parameter now, and your player can use a new add_item function to place what ever you want into their inventories.
extends StaticBody3D
@export var held_item: InventoryItem ## new line
func interact(player: Player):
print("interacted")
player.add_item(held_item) ## new line, you must make `add_item` on your player
queue_free()
Does that mean these functions are push_backing the player? Or does your player have an Area3D for interactions in addition to a body? Could you share your interactable and player scene tree?
but if my interactable instance isnt a child of the player, but a child of the object, what do i do?
