Passing arguments to root node when instancing a scene?

I have a scene who’s root node takes some arguments at instantiation time (that is, in _init(arg1, arg2). Unfortunately, I don’t see a way to pass arguments to said node when instance()'ing the scene containing it.

If I just blindly call instance() anyway, it seems like the node is simply ignored. Is there a way to do this?

I had the same problem and solved it with a very ugly hack

There is currently no built-in way to pass arguments to a scene like that. You have to call a function of yours probably, like this:

var scene = preload("your_scene.tscn").instance()
scene.initialize(params) # init root node

There might be only one case where _init will be called, is when you do this:

var node = preload("").new(params)

But for scenes, you have to go the other way.

Thanks, I did a preload("").new(arg1, arg2), where instantiates its child nodes in _ready(), and that indeed worked.

Is there any particular reason to use scenes instead of a script like this then? I suppose if you have custom collision shapes or some node which really wants to be set up with the editor, that might be a good reason to use a scene. Is that the only reason?
