Unable to iterate on object of type 'Object'.

Butab pretty similar error

Your error is a completely different one.

Butab Caller thread can't call this function in this node

Post the exact code that caused that error.

Yes it's different, I meant Unable to iterate on object of type 'Nil'. error is looks pretty same, sorry for the confusion

`func thread_process(userdata):
while(true):
for c in objects.get_children():
var cx = c.object_position.x
var cz = c.object_position.y

		var px = floor(player.position.x / Global.DIMENSION.x)
		var pz = floor(player.position.z / Global.DIMENSION.z)
		
		var new_x = posmod(cx - px + load_radius/2, load_radius) + px - load_radius/2
		var new_z = posmod(cz - pz + load_radius/2, load_radius) + pz - load_radius/2
		
		if (new_x != cx or new_z != cz):
			c.set_object_position(Vector2(int(new_x), int(new_z)))
			c.generate()
			c.update()`

Butab MyScriptNameHere.gd:25 @ _thread_process(): Caller thread can't call this function in this node (/root/World/Chunks). Use call_deferred() or call_thread_group() instead.

What is line 25 of MyScriptNameHere.gd?

DaveTheCoder

for c in objects.get_children():

If what, objects is onready variable with $Objects value

DaveTheCoder Either call it using call_deferred, or place its contents in a separate function, and call that function using call_deferred.

Tried, game launched and after few seconds Windows says it's not responding lol

Thread_process is called with: load_thread.start(Callable(self, "_thread_process").bind(null)) at _ready() function

Looks like we are going in circles here. A few observations:

• call_deferred is not useful in this case. call_deferred("get_children") will always return null. You can't get return values via call_deferred. Calling the entire function deferred also does not make sense. Your are trying to run code in another thread. But call_deferred puts it back into the main thread
• The main issue is objects. What is it? A node that is part of the scene tree? If yes, then what you want to do is impossible. You can not manipulate the scene tree from another thread. The scene tree is not thread-safe.

You could try replacing:

load_thread.start(Callable(self, "_thread_process").bind(null))

with:

(func(): load_thread.start(Callable(self, "_thread_process").bind(null))).call_deferred()

I haven't used Threads in Godot, and don't know if that will make a difference.

That's from a hypothetical document called "Weird lambda tricks".
