How to add extra parameters to godot signals

[tame cipher]

I want to send the variable "numero" in the signal "_on_body_entered", but if i put that extra parameter in both functions, the code i set for each function stops working (in the case of the player, it doesnt do the commented thing, in the case of numeros, they dont queue_free)

Im confused because this is kinda how the custom signals works

also, this is how i connected those two signals in the third image, i just saw i should put the parameter in that connection but i dont know how to do it

I don't really understand what you're trying to say, especially since some of the code is in spanish, but this is how to make custom signals with parameters:

signal mySignal(param : int)

func _ready() -> void:
  self.mySignal.connect(signalFunction)
  self.emit_signal(mySignal, 12)

func signalFunction(param : int) -> void:
  print(param)

I think you can add custom parameters to built-in signals

if you add the parameters in the connect function

Like this:

func _ready() -> void:
  self.body_entered.connect(bodyEnterFunction, 12)

func bodyEnterFunction(_body : CharacterBody2D, param : int) -> void:
  print(param)

also, it's considered good practice to NEVER connect signals with the editor, and only connect signals using the .connect() function with code

*not never, just for many cases. If you're designing a level made out of pieces that communicate via signals, for example, you should not be making a script to connect all of the signals, and rather be doing it in the editor.

stack overflow has this answer about binding extra arguments to a signal object.signal_name.connect(method_name.bind([extra, arguments])) https://stackoverflow.com/questions/77360041/how-to-connect-a-signal-with-extra-arguments-in-godot-4

[ocean spindle]

well this is also wrong. bind expects arguments to be passed one-by-one, if you want to pass them in an array like this, there is bindv: https://docs.godotengine.org/en/stable/classes/class_callable.html#class-callable-method-bindv

[tacit gazelle]

in that case Iw ould still use .connect() using code

since connecting it with editor is too hard to manage

[modest crown]

That would be absurd; you'd have to make an entire extra script for every single level with a million string references; it would be harder to manage and easier to break. Yes, you can. No, you shouldn't.

Nah, just add it to an existing script
