Hi,
I have a scene that repeats multiple times - lets say travel.tscn - in my game but with different parameters (like different texts) I want to change the scene to travel.tscn but before that I want to set those parameters. I searched and didn’t find any solution. For now I use global node. I defined some parameters in global.gd and I set them before change scene and I read them in travel.tscn. Is there a better method for doing this?
That is the best method! Are you having any issues using that method, or did you just not think that was the best way?
I think this is not a good method! Now I have another scene that has parameters. These parameters are mixed and it causes so many bugs! I think this is a really simple feature that Godot should have!!
Autoload singleton’s are one solution, but it does feel akward having more state just floating around in some global. Another solution is to handle the scene change yourself:
To get finer control over changing scene, you’ll have to add and remove scenes directly with sceneTree.add_child and sceneTree.remove_child(or delete the node with free() or hide it’s visibility). They’re a couple of ways to do this in the docs.
Basically:
Instantiate your scene directly
Parameterize your new scene
Add it to the sceneTree
Remove/delete/hide the last scene
In code this would look something like:
# We instantiate the scene before we add it
var travel_scene = load("res://travelScene.tscn").instantiate();
# parameterize the scene
travel_scene.location = "Hell"
# Add the scene as a child to the sceneTree
get_tree().get_root().add_child(travel_scene)
# Delete the last level
# You could also hide it's visibility or hard delete it
# You're use-case will determine which.
get_tree().get_root().remove_child(last_level)
