Hey, this is my first project with Godot, so this may be an easy fix, however I can't seem to find it. Essentially what I am trying to do is that when the 'killzone' has touched the player, i want it to call a function within the player node, but it keeps coming up with the error of the Node not found ( see images ). I managed to apply this logic and create a functioning coin counter for the game, so i was able to call a function within another node but for some reason isn't working here. If somebody can please elaborate so that I won't make this mistake in the future. Thanks in advance. (images attached are the functioning coin system and the nonfunctioning death system)



  • xyz replied to this.

  • Eyaan I see the brackeys tutorial is taking victims.

    if the player is some global thing, manage it's demise through an autoload.
    it's a bit advanced, but:
    in the autoload, let's call it player_manager, create a signal, call it something like kill_player

    signal kill_player

    in player ready(), connect the signal to a function that kills the player. you have one called killed_(), let's use that:

    func _ready():
     PlayerManager.kill_player.connect(killed_)

    when your area triggers, call the signal in the autoload:

    func _on_body_entered(body)
     PlayerManager.kill_player.emit()

    autoloads are unique and run outside the scene. when the game starts, it creates nodes with the autoload scripts. you can access autoloads from anywhere, as they are given a unique name (the name of the file, capitalized and without spaces)
    player_manager becomes PlayerManager

    if the player is the one colliding with the coin and dead area, you don't need anything special, the function has a body parameter and that is going to be the player:

    func _on_body_entered(body):
     body.killed_()

    body is the player. you can change the names of these variables

    func _on_body_entered(player):
     player.killed_()

    if something other than the player can collide with this thing, you have to check for method first or do some other test:

    func _on_body_entered(player):
     if player.has_method("killed_"):
          player.killed_()

      Eyaan Scene unique node names are only valid inside the scene they're defined in.

          xyz Thanks for the reply, however (this may sound a bit dumb) how is it i am able to link the UI with the 'coins' using the unique names. Also when not using the unique names, i still ran into this problem.

                  Thanks for the reply, your solution worked! Now I'm getting the correct function running without any errors. However the whole point of this function was in order to play a death animation, which is not occurring, it still either plays the idle animation or the running animation. I think this may be due to how the code is set up. I was wondering if you could suggest a way to fix this? The way i went about this is with if and elif statements, and in my head i thought it would run through the if statement first, and if fulfilled it will not run through the others? (Don't worry i didn't forget to define the variable) Thanks in advance.


                      Eyaan use states for the player.

                      #0 would be idle
#1 could be swim, climb, etc
#2 death
var state : int = 0

                      in your main function, _process if you are using process or _physics_process, or both, check the states with match:

                      func _physics_process(delta):
     match state:
          2:
               #death
               animated_sprite.play("death")
          _: #_: is the same as 0, or any number not being checked, it's like an else
               #idle
               if is_on_floor():
                    if direction == 0:
                         animated_sprite.play("idle")
                    else:
                         animated_sprite.play("run")
               else:
                    animated_sprite.play("jump")

                      when you run killed_, it should change the number. adding 1 would just cause it to accumulate and it would no longer be 1, in which case you should check if dead > 0 or dead != 0. but with states you just assign the state:

                      func killed_():
     state = 2

                      and then when trying to enter a different state, like going into climbing, you check if the state is not 2.

                          Jesusemora Thanks this worked perfectly, however now i think I'm going to take a crash course in GDscript before i continue on with attempting at making games. 😅
