tutorials/migrating/upgrading_to_godot_4.3

For most games and apps made with 4.2 it should be relatively safe to migrate to 4.3. This page intends to cover everything you need to pay attention to when migrating your project. Breaking change...

If you have a Node3D parent of a top_level Node3D, moving it won't affect it's child as expected. In 4.2 the AABB box didn't account for that, now it does in 4.3 and increases as you move the parent node from it's child. On top of that, in 4.3, for some reason my Parent node teleports to it's child node position when the game begins, that made me disable top_level in editor and enable it by code in _ready() function

If you use GDExtension, keep in mind that creating bound Godot classes will crash your game from now on. Examples:

Instead of: RandomNumberGenerator rng;
Use: Ref rng; rng.instantiate();

Instead of: SphereShape3D* sphere = new SphereShape3D();
Use: SphereShape3D* sphere = memnew(SphereShape3D);

[NatGazer]

Ups, text formating removes <>. Here's the correct way:

Instead of: SphereShape3D* sphere = new SphereShape3D();
Use: SphereShape3D* sphere = memnew(SphereShape3D);

Instead of: RandomNumberGenerator rng;
Use: Ref<RandomNumberGenerator> rng; rng.instantiate();

[FireCatMagic]

Ref<RandomNumberGenerator> rng = Ref(memnew(RandomNumberGenerator)); also works

Where is the autoload scripts ? It seems to have disapeared from the project settings...

Found it ! It's in Project > Project Settings > Globals

I am creating 2D action RPG game with a top-down view, on 4.2.1. Does it make sense to upgrade to 4.3?
