Is there a way to connect a signal from a scene dynamically created?

[night quail]

I would like to emit a signal when my bullets hit an enemy, but that bullet is dynamically created and I was thinking about connecting that bullet's signal with a different ui node, but idk if what I want even makes sense lol

is there a way to achieve this somehow? or maybe doing it in an alternative way?

[meager linden]

can you get a reference to the ui from where you're creating the bullet?

[night quail]

good question

I think I can do something like get_node("../ui")

would it be a good idea?

but is there a way to connect my bullets with the ui without doing it manually through the signals section? the bullets are only created during gameplay @meager linden

You can look at the "connect" call, it will connect signals programmatically:

var myBullet = <get a reference to the bullet>
myBullet.connect("signal", .......)

Look in the documentation, there is examples of this.

yeah, I was just reading about it, I think that will work

thanks

do you know if I can get the nodes name somehow?

im trying to print a function about the name, but it gives me @CharacterBody2D@22:<CharacterBody2D#39107692062> lmao

[balmy pelican]

There are variaous ways, but without seeing how you create your bullets I don;t believe anyone can answer that.

That's it's name probably. If you are creating an instance , Godot will just give it a seemingly random name.

[night quail]

thats supposed to be the name of the thing it hit

for example this is one of the enemies, is there a way to get that Enemy1 label?

[balmy pelican]

You'll have to get it when it's instanced.

Or maybe I'm not following you.

Also, very good info here in the "Connecting Signal via Code" section: https://docs.godotengine.org/en/stable/getting_started/step_by_step/signals.html#connecting-a-signal-via-code

[night quail]

thanks

I got the signals stuff working just fine

now its printing what my bullet hit, which in this case is that Enemy1, but I also have other enemies

but idk if I can differentiate if I hit one or the other

its only giving me the reference which doesnt tell me much

[atomic sentinel]

your code likely will

it doesnt do things based off of the name you dont have to worry about that

[night quail]

right, but I would like to differentiate the enemies in order to get a different score

when I kill any of them

[atomic sentinel]

then you have two options i believe: just getting their name via enemy.Name or groups

do you know about the groups system

[night quail]

not really

was also trying to get the name, but it gives me some weird stuff

if I do node.name I get @CharacterBody2D@21

I was reading about unique names, but my character 2d doesnt have that option

[atomic sentinel]

its like tags in other software

you can go to the same panel where you connect signals, and click groups

you can add new groups to your nodes there

you can for example add a “StrongEnemy” group to a Strong Enemy and then use code to check the group and drop a certain amount of coins based on if it’s a strong enemy or not

[night quail]

thats interesting, im gonna do that then, seems to be a good solution

[atomic sentinel]

i dont believe that’s what unique names are for, are you sure you’re printing node.Name?

yeah its less fragile than hardcoded names

[night quail]

yeah

but anyways, im gonna do that thing about groups

thanks bro
