This guide explains how to get nodes, create nodes, add them as a child, and instantiate scenes from code. Getting nodes: You can get a reference to a node by calling the Node.get_node() method. Fo...

Note that all nodes will only be available at runtime, therefore, if you set a variable to a node with a node path, it must have the @onready attribute

[guiYudi]

Worth noting the order in which nodes get loaded and call their _ready(), a.k.a. the Tree Order: https://docs.godotengine.org/en/stable/tutorials/scripting/scene_tree.html#tree-order

I had an issue where i could move but not rotate an instanced scene from code.
Turns out, i was applying a rotation before calling "add_child(instance)", which seemingly reset the rotation but not position.

So always add the instance to the tree before doing anything else with it i guess.

When using physics interpolation, objects' positions should be set before adding them to the scene tree. Otherwise, you'll have to call Node.reset_physics_interpolation() on the node afterwards, which is wasteful in terms of performance.

Setting properties on a node post-instantiation also has various other ramifications (especially performance-related), as some operations will essentially have to run twice on initialization rather than just once. This can have a significant cost if you're instantiating dozens of nodes in a single frame.

Question: Is it possible to manipulate an instantiated object from the script it was created from? I would like to do this to cause instantiated objects to spawn in front of the player

[llukehaskell]

What is the difference between doing the .load("path") and doing

@export var example_scene: PackedScene

and then populating the scene in the Inspector panel by dragging the appropriate .tscn file on to it?
