Singelton to handle signals ?

Whiningfields

Hi, I can't get my head around the signal syntax with the use of a singleton. I've created the singleton (Events) and set it up to autoload: Events script:

signal health_updated(msg)

Healthbar script (in a hud):

Events.connect("health_updated", self, "_health_updated")

In the player script I have

func _set_health(value):
	var prev_health = health
	health = clamp(value, 0, max_health)
	if health != prev_health:
		Events.emit_signal("health_updated")

From what I've gathered this is the formula for emitting signals:

Events.emit_signal("health_updated", {destination = destination})

But how do I set the "destination = destination" parts- what's missing to actually update the Healthbar?

Input much appreciated - specifics even more.

Thanks!

I'm not sure what destination is supposed to do... I think it might just be confusing things.

To update your health bar you should have _health_updated accept an argument (the player's current health). And when your player's health changes simply send along the new value when you emit the signal. Your setup should be something like this:

Events.gd

signal health_updated(new_health)

Health bar script

func _ready():
	Events.connect("health_updated", self, "_health_updated")


func _health_updated(new_health):
	# update health bar here
	pass

Player script

func _set_health(value):
	var prev_health = health
	health = clamp(value, 0, max_health)
	if health != prev_health:
		Events.emit_signal("health_updated", health)

I hope this helps
