In my game i have levels that are divided into waves. I have code to see if the current wave is finished, but i want to make it so that when it is it runs a function in the main to switch to the next wave using signals. I want the same code to run every time however, so how can i run the same function with signals from different nodes? Only 1 one is instanced at a time.
Can’t a signal from multiple nodes attach to the same function?
If i understand your question correctly, you are trying to make all the objects that connect to your signal call a particular function.
one way to go about it is to pass the object that is emitting the signal along with the signal Eg. When you are calling the wave, you do something like this
# Wave Caller class
...
# new wave starting
emit_signal("new_wave", self)
....
func wave_action(wave_object):
# this is the single function that all connected object will call
then when an object connects to it, in the callback function, you do something like this
Another way to also go about it is using FuncRef, but i don’t think that optimal in situations like this. I just hope this is what you are looking for
Thank you very much! I still have one issue however. The signal still doesn’t connect? I have this in main:
extends Node
var waves = ["res://Scenes/Levels/Waves/Wave 1.tscn","res://Scenes/Levels/Waves/Wave 2.tscn"]
var wavenum = 0
var currentwave = load(waves[wavenum]).instance()
func new_wave(wave):
add_child(wave)
wave.connect("new_wave",self,"_on_new_wave")
func _ready():
new_wave(currentwave)
func _process(delta):
pass
func _on_new_wave():
print("wave over!")
and in the wave script i have this:
extends Node
export (bool) var finish = false
onready var children = get_children()
var flock
var blockmap
func _ready():
add_to_group("wave")
for i in children:
if i.is_in_group("flock"):
flock = i.get_name()
if i.is_in_group("blockmap"):
blockmap = i.get_name()
print("hey the sequel")
func _process(delta):
if get_node(flock).get_child_count() == 0 and finish == false:
finish = true
emit_signal("new_wave")
for i in get_node(blockmap).get_children():
i.loop = false
if get_child_count() == 0:
queue_free()

Ok so i realized that the wave will always be a child of the main, so i just did get_parent and called the function from there. Thanks for the help anyway!
