Signal connection on parallel scenes
#Signal connection on parallel scenes
rapid ember
I thank you
dapper dawn
what are you using the signal for?
rapid ember
but more or less 5yo explanation is: I change state, then cursor changes to sprite, sprite must reach area2d of fountain, fountain emits "materials" it has, on area exit it doesn't, or rather emits nothing
sounds like utter bullshit but I'll make it exist first with thoughts and prayers

How did this break with a global signal?
rapid ember
How did this break with a global signal?
I didn't figure out how to wire everything like it was before
I added it to global and then had ape cymbals gif
rancid anchor
I didn't figure out how to wire everything like it was before
Well for starters make your autoload script and define your signals
rapid ember
Well for starters make your autoload script and define your signals
did that, and that's about all I did
rancid anchor
Can I have a looksee at the script?
dapper dawn
indeed, would help lol
rapid ember
Can I have a looksee at the script?
there's like, signal definition and nothing else
because I never connected anything before with just code
rancid anchor
Does it include things you'd like to pass with the signal?
rapid ember
so don't have reflex on how to
dapper dawn
there's like, signal definition and nothing else
you'd need to connect the signal to the callback function you want to run when the signal is emitted
i know how to do this with C# events, but i kinda forgor how to do this in GDS lol
rapid ember
you'd need to connect the signal to the callback function you want to run when t...
what's callback here? function without parents?
dapper dawn
but as an example in C# you'd connect your event on _ready(), to the function you wanna run when it gets emitted
rancid anchor
you'd need to connect the signal to the callback function you want to run when t...
Just do GlobalSignal.signalname.connect()
dapper dawn
like line 51 (for parameters) or line 52 (functions without params)
(ignore everything else in the image lol)
i assume a similar principle is used with Godot Signals
rapid ember
so function without parents
nods
would you also happen to know how to make a collection of unique elements?
dapper dawn
as in an array of a class? (like an array of class_name player for example)
or a dictionary?
rapid ember
just something that only takes in unique values, or at le
wait
you're genius thanks
I can just track quantity of material and subtract if it goes away
instead of fucking
readding and reremoving it back and forth
how did I not think of that 🤦♂️
you're wonderful person
dapper dawn
lol
rancid anchor
Context is important.
dapper dawn
explaining something you're working on sometimes helps you solve the problem yourself
rapid ember
Context is important.
see, if you hover over 2 fountains, you get two water material, and if done wrong, you can get in a limbo where you either have all water or none, which is bollocks
rapid ember
explaining something you're working on sometimes helps you solve the problem you...
nah, I tried many times for weeks
it flashed only now
and before you nobody was too willing to listen anyway
dapper dawn
get a reference to the autoload node with the global signal script and connect to the signals
dapper dawn
and before you nobody was too willing to listen anyway
well glad i could help lol
rapid ember
well glad i could help lol
oh you fucking did
way more than you think actually
so...
is there a caveat on disconnecting signals from stuff that's gone?
dapper dawn
i don't think so
in a modern engine like Godot it should just clean it up for you if you delete a node with an event (signal) that isn't disconnected
dapper dawn
is there a caveat on disconnecting signals from stuff that's gone?
yea no i don't think there is
rapid ember
but how to connect signal to newborns then
dapper dawn
newborns? lol
you mean nodes that are instanced (created) at runtime (while the game is running)?
dapper dawn
you'd do something like this
on their _ready() function
which is called when they're instanced and ready to be used
rapid ember
nay
you connect from global script which always exists no?
but things that change are ones you connect to
how would you "request" global to connect to you on your ready 
dapper dawn
no, you don't have global connect to your node
you have your node connect to global
you'd define the signal you wanna connect to in the global script
rapid ember
just define signals there
it's a warning in editor then
rancid anchor
In your other scripts, like area or player, you'd connect them.
rapid ember
In your other scripts, like area or player, you'd connect them.
here's where I don't get it again
rancid anchor
Which part?
rapid ember
connect where from/to
rancid anchor
Say we have a global "damage" function.
GlobalSignal.gd (autoload)
signal damaged(Hurt: CharacterBody3D, Source : CharacterBody3D, DamageTaken : float)
func _ready():
GlobalSignal.damaged.connect(_on_damaged)
func _on_damaged(Hurt: CharacterBody3D, Source : CharacterBody3D, DamageTaken : float):
pass
So the signal is sent out to all nodes, you just need to tell them to listen for the signal.
rancid anchor
Sending the signal is as easy as GlobalSignals.damaged.emit()
(don't forget to pass variables needed)
rapid ember
yeah I thankfully know how to send, as I mentioned it was working alright
just never been connecting via code
rancid anchor
Also no promises that the code functions as is I don't have access to Godot atm so syntax might be slightly off
But that's the general idea.
rancid anchor
What about em
rapid ember
I've been there, I've given my player class_name and called it a day, since I don't know what else I'm supposed to do with it
rancid anchor
I mean you don't have to do anything
rapid ember
how so
rancid anchor
Classes are useful when you want to define additional functions
rapid ember
which I do
rancid anchor
Like your player might have things that regular CharacterBodies don't have
rapid ember
wish I knew what they have to begin with...
rancid anchor
It's all in the documentation
So this is the general chain of inheritance
adding a class name to your script like:
class_name Player
extends CharacterBody3D
Just adds another chain in the link
rapid ember
more of a C# example, but the concept would be the same for GDS
stupid question?
dapper dawn
go ahead
rapid ember
why not Unity at this point in your case
dapper dawn
lmao
well in my case i don't tend to use signals, i usually use C# events
but to answer your question...
1st: Godot is open-source, Unity is not
if Godot suddenly decided to ruin their engine, i could just yoink the source code and fork it
2nd: Godot has a much better user experience than Unity
rapid ember
1st: Godot is open-source, Unity is not
as if many people care (ie can benefit from it)
dapper dawn
2nd: Godot has a much better user experience than Unity
i still remember having the Unity editor crash on me 3 times a day, haven't had Godot crash on me once in 2 years
3rd: Unity is *Free™ (* free until you pass a certain treshold), Godot is just free
deep cosmos
as if many people care (ie can benefit from it)
They do, in fact. Care. For example look at the 'Runtime fee" fiasco. Even though Unity backtracked that decision. A lot of dev jumpship just from that alone.
dapper dawn
yea
not to mention you don't know what kind of spyware telemetry they potentially have packaged in there, with that whole "oh we will know if you meet our requirements to pay install fees" talk
with Godot that isn't an issue, you can pull apart the source code and analyse it yourself
not to mention yea, 4th: you can modify the engine code if you need to
i actually did this in a project, to add engine support for FFB
rancid anchor
Not to mention follow along with development when you have engine issues 
dapper dawn
Not to mention follow along with development when you have engine issues <:gdpra...
SDL input implementation my beloved
i followed that github pull request for months lmao (https://github.com/godotengine/godot/pull/106218)
rapid ember
hmmm but Unity has better uh encryption?
rapid ember
you can also do that in Godot
word is on the street it's barely enough
not that I'm zealous about it, but so I've heard
as well as it's possible to extract that key with reversing like ghidra
dapper dawn
maybe, i'm not a security expert
but sure, let's assume so, why should i care as an indie dev lol?
my projects are small singleplayer games, they don't exactly need top notch asset security
rapid ember
but sure, let's assume so, why should i care as an indie dev lol?
because people might resell your stuff or use your brilliant code to make stuff they sell under own name
yada
wait what were we talking about
I wanted to make a game
then something happened and we ended up with this encryption talk, as if someone needs to encrypt something right now
dapper dawn
because people might resell your stuff or use your brilliant code to make stuff ...
well if you're worried about code theft don't worry, if someone is smart enough to decrypt & decompile binaries into usable source code (that's the tricky part) then they're smart enough to make their own game code
dapper dawn
wait what were we talking about
you asked if you could ask a question
rapid ember
I really need to get thoughts straight ||or gay||
rapid ember
didn't tell me much for some reason
dapper dawn
at 9am? okay
not my timezone lol, different hour for me
