Parent of go created by factory

Questions
1

Hello, obviously I have some misunderstanding how factory works, can someone explain please?

so, here is my project structure

main.collection
—game.collection
------board.go
---------BoardController.script
---------BaseTile.factory

inside of BoardController script

print(msg.url());--DEBUG:SCRIPT: url: [main:/game/board#BoardController]
print(board_id); -- DEBUG:SCRIPT: hash: [/game/board]
print(tile_type);--  DEBUG:SCRIPT: BaseTile
local factory_url = msg.url(nil, _id,  tile_type);
print(factory_url) ;-- DEBUG:SCRIPT: url: [main:/game/board#BaseTile]
local tile_id = factory.create(factory_url, scene_pos, nil, {tile_color = color});
pprint(msg.url(tile_id));--DEBUG:SCRIPT: url: [main:/instance0]
go.set_parent(tile_id, board_id);
pprint(msg.url(tile_id));--DEBUG:SCRIPT: url: [main:/instance0]

my question is, why created “instance0” is not child of “board.go” when it just created?
And why “go.set_parent(tile_id, board_id)” doesn’t do nothing here?

It is by design. For some games it might make sense to have the spawned object a child of the factory component but for others it doesn’t make sense at all (like bullets being fired from a weapon).

This is actually an asynchronous operation. The game object will not become a child until the next frame. (and yes we do not explain this in the documentation, I will make sure this gets updated)

Оh "asynchronous ", now it is clear :slight_smile:

by the way it could be nice feature to tell factory where to spawn objects.

Thanks for fast (and furious) response!

cheers!

Did you try the position parameter? Or do you mean something else?

No, by “where to spawn” I meant making them children of some specific gameObject.
e.g in my case I would like say to factory to spawn “tiles.go” in to “board.go” by default.
But this is only suggestion.

I agree, a parent option in factory.create() and for collectionfactory would be very useful.

Was something like this ever added?

No, it has not been added. You need to set the parent object after creation, or set up the hierarchy in a collection and use a collection factory.
