#

Different roles require different interactables and interacting components. I have trouble because they are sometimes intersecting with each other despite their different layers and masks ;;

#

Scripts overview

Hack_interactable - The one that the hacker can interact with (Lock)
Hack_interacting_component - The node that the hacker has (Key)

Dev_interactable - The one that the dev can interact with (Lock)
Dev_interacting_component - The node that the developer has (Key)

TaskArea - The one being interacted with (Contains both hack_interactable and Dev_interactable)

#

What's the code for the actual object you're interacting with?

lunar dirge What's the code for the actual object you're interacting with?

Wait >>

wide wasp Apr 20, 2025, 8:59 AM

#

Yeah the problem definitely lies between the else you showed, and the hack_interactable_2d.gd script

swift shadow Apr 20, 2025, 9:00 AM

lunar dirge What's the code for the actual object you're interacting with?

It's the task.gd, the one I wrote up

wide wasp Yeah the problem definitely lies between the else you showed, and the hack_inter...

Ohh

wide wasp Apr 20, 2025, 9:00 AM

Can you show the code for both of these ?

Ok ^^

I'm still not seeing any is_developer variable nor function.

Aha, sorry. There it is.

wide wasp Apr 20, 2025, 9:03 AM

#

Whenever you enter any area, it goes in "current_interactions"

swift shadow Apr 20, 2025, 9:03 AM

#

wide wasp Ok I found the problem

Oh

wide wasp Apr 20, 2025, 9:03 AM

#

Do you know about groups ?

#

They might solve the problem you're facing with the is_developer and is_hacker booleans

swift shadow Apr 20, 2025, 9:04 AM

#

wide wasp Do you know about groups ?

Yeah, I've recently added the hacker and developer interacting component in their respective groups

wide wasp Apr 20, 2025, 9:04 AM

#

Ok, so instead of using the is_hacker boolean for example

#

You do if yourVariable.is_in_group("hacker"):

#

And if you need to dynamically change what groups they belong to, you can also do that via code iirc

#

#

If you need more details about them, here's a link to the doc : https://docs.godotengine.org/en/stable/tutorials/scripting/groups.html#managing-groups

Godot Engine documentation

Groups

Groups in Godot work like tags in other software. You can add a node to as many groups as you want. Then, in code, you can use the SceneTree to: Get a list of nodes in a group., Call a method on al...

swift shadow Apr 20, 2025, 9:07 AM

#

oh so I'll replace the current_interactions[0] with variable.is_in_group("hacker"):

wide wasp Apr 20, 2025, 9:07 AM

#

current_interactions[0].is_hacker but yeah

#

You could even (not necessary but I like doing it that way) add an "interactable" group, and before adding anything to "current_interactions", you check for that group

#

Because nodes can be in any number of groups at the same time

lunar dirge Apr 20, 2025, 9:08 AM

#

Another thing to consider is adding if current_interactions[0] is dev_interactable: and adding a class_name to your dev_interactable object to differentiate them. That way even if you do get a rogue area in the list, it won't crash the game.

wide wasp Apr 20, 2025, 9:10 AM

#

Yeah the classname approach is even better
Only downside is that you can't change class_name at runtime

swift shadow Apr 20, 2025, 9:11 AM

#

Oh I see I see. I think I'll go with the classname approach for now since I know this sounds stupid but I don't know which variable it is we're talking about, sorry :')) I only assigned the interacting components to their respective groups and not variables. Also, I don't think I'll have to change class_names during the game

#

Thanks a bunch!! I'll test it out now ^^

#

changes implemented ^^


func _process(_delta: float) -> void:
    if current_interactions and can_interact:
        current_interactions.sort_custom(_sort_by_nearest)
        if current_interactions[0] is dev_interactable:
            interact_label.text = current_interactions[0].interact_name
            interact_label.show()
    else: 
        interact_label.hide()

#

Will test it out now

swift shadow Apr 20, 2025, 9:24 AM

It works now, thanks ^^

#

I'm encountering a bug though, all the code reads is the _developer_interact and _hacker_interact

wide wasp Apr 20, 2025, 9:26 AM

#

swift shadow I'm encountering a bug though, all the code reads is the _developer_interact and...

I'm not sure I understand, what are these ?

swift shadow Apr 20, 2025, 9:28 AM

#

wide wasp I'm not sure I understand, what are these ?

It can't seem to read when an area is entered. It's supposed to print something out

#

Wait hold on, I have a fix in my mind

#

I'm gonna try to implement it

#

it could be a simple layer and mask issue I think ?
