Hello guys, I’m trying to make a simulation in Godot on multiple threads, I’m trying to implement a small MAS(Multi-agent system) in it just for the simulation purpose.
In other words, I’m trying to spawn N NPCs(agents) which they are going to attack each other if they are going to be found one by another.
Each agent is a scene in which I want to be placed on separate threads and also I want them will be distinct one to another.
But not raise the question, can I do that? Or I can just instance each one of them?

var dragons = 3
var screen_size
var dragon = preload("res://Player.tscn")
var thread_1
var thread_2
var thread_3
func _thread_function(userdata):
var x = floor(rand_range(0, screen_size.x))
var y = floor(rand_range(0, screen_size.y))
var dr = dragon.instance()
dr.start(Vector2(x,y))
call_deferred("add_child", dr)
func _ready():
screen_size = get_viewport_rect().size
thread_1 = Thread.new()
thread_1.start(self, "_thread_function")
thread_2 = Thread.new()
thread_2.start(self, "_thread_function")
thread_3 = Thread.new()
thread_3.start(self, "_thread_function")

Could any of you explain to me what I’m doing wrong? And also if it’s possible at least o instantiate each Player.tscn on an individual thread.
