I can call the class, but how do I call the function?
This is the code for the class I want to call.
#MyClass.gd
class_name MyClass
func FuncA():
pass
I want to call FuncA in this class.
#Player.gd
extends KinematicBody
func _ready():
var myClass = MyClass.new() #Non Error.
myClass.FuncA() #This is Error.
Sorry for the elementary question. Am I missing something?

UPDATE - The below answer was based on a misunderstanding of the original question. See the conversation in comments below for more helpful information. (I wish the forum supported strike-through text for better visibility here…)
You’re probably running into the same misunderstanding as described (and resolved) here:
https://forum.godotengine.org/16097/how-do-you-call-class-methods-from-an-external-gdscript-file
I have done the same but it does not work.
its Q&A seems to have calling a script, but I seem to have calling a reference on my end.
Also, what is the difference between “class” and “class_name”?

Hmmm… Sorry, looks like I misread your post. What you show should work as expected.
If I create a file named MyClass.gd with this content:
class_name MyClass
func FuncA():
print("Called FuncA")
… and then, from another script, do this (for example):
func _ready():
var myClass = MyClass.new()
myClass.FuncA()
The function is called and I see called FuncA printed in the console. Is what you’re doing somehow different?

To your earlier question class_name just registers a name (and, optionally, an icon) for the class represented by the current script. Theclass keyword creates an inner class.
Search for those terms here for more info: https://docs.godotengine.org/en/stable/tutorials/scripting/gdscript/gdscript_basics.html?highlight=class_name

I was trying different things and it worked!
As a matter of fact, I had named the class StateMachine (for clarity for questions).
It did not work with the name StateMachine, but it worked fine with the names MyStateMachine and StateMachine_.
I didn’t understand what was going on, but it worked anyway. Thank you for your patience.
