Functions on autoloads can be called from any scene in the Scene Tree. Like:
AutoloadName.a_function_inside_the_autoload_script()
You can pass variables to the autoload in the parenthesis.
The Autoload however should send signals to trigger functions in other scenes. These target scenes should call the connect() function inside of their _ready() function.
When using connect(), you need to tell the code which function in the scene is called every time the signal is emitted.

Example fake code - 1/2
This example code increases a global score value by one (1) every time a coin is collected. Then, it updates the UI counter accordingly.
- « Manager » is autoloaded
- An instance of « Coin » is loaded every time an enemy dies
- « Score_UI » is a Label2D on the main scene
Script on Coin:
var score_increase: int = 1
_whatever_you_use_to_check_collisions():
when_collected()
when_collected():
Manager.coin_collected(score_increase)
@Natanox
Example fake code - 2/2
Script on Manager:
signal score_changed
var score:int = 0
coin_collected(score_increase):
score += score_increase
score_changed().emit(score)
Script on Score_UI:
_ready():
Manager.score_changed().connect(update_score(score))
update_score(score):
text = score
Please please please check documentation for actual syntax and appropriate calling of functions. I wrote this on my phone super quickly.
Check the docs for Custom Signals, as well as functions emit() and connect()
Hopefully the logic makes some sense. It has been working great for me!
Hope that helps!
