Extra code in Practice 1intent-mantisIn the practice 1 script, one of the instruction comments inside the advance function says
# Don't forget to call the show_text function
I believe this comment is left over because this script uses show_image instead of show_text

Consequences of L6 challengeLtommasiniAs I have done the L6 challenge about changing the duration of the tween according to the lenght of the text, I also had to do some adjustments regarding it:
```gdscript
func show_text() -> void:
var curr_item := dialogue_items[curr_item_index]
rich_text_label.text = curr_item["text"]
expression.texture = curr_item["expression"]
rich_text_label.visible_ratio = 0.0
var tween = create_tween()
#var text_duration := 1.5
var text_duration :float = curr_item["text"].length()/8.0
tween.tween_property(rich_text_label, "visible_ratio", 1.0, text_duration)
var sound_max_length := audio_stream_player.stream.get_length() - text_duration
var sound_start_pos := randf() * sound_max_length
audio_stream_player.play(sound_start_pos)
tween.finished.connect(audio_stream_player.stop)
```
In line 8 I had to declare the "text duration" var as a float otherwise it wouldn't work, but I don't really understand why. The error I get is: "Cannot infer the type of "text_duration" variable because the value doesn't have a set type."
It also affects lines 10 and 11, same error.
Not sure if the solution I have here is the best one, but it's working fine.
Thanks! I'm really enjoying the course progression34May. 14, 2024

About Practice L10.P2AJ StudiosI was able to get it right except on the `show_party_member()` function I got an error stating: *Value of type "Dictionary" cannot be assigned to a variable of type "String".* I missed hint #4 where it says: each item has 2 properties, portrait and name.
I was confused since in the previous practice: L10.P1 we accessed the textures by: `texture_rect.texture = items[item_index]`. Then I realized that L10.P1 Array is of type Texture, and L10.P2 Array is of type Dictionary.
I have to admit, this one really got me. Nonetheless I just learned something new. 12May. 23, 2024
Error: Function "length()" not found in base Dictionary.Nikita MyshkinThere was a task in the previous lessons. So that the duration of text input should be depending on its volume. Here is an excerpt of the code: `var text_appearing_duration := current_item.length() / 30.0`
Now that we've added the array of dictionaries, it throws this error: *Parser Error: Function "length()" not found in base Dictionary.*
I have already tried to fix: `var text_appearing_duration := current_item["text"].length() / 30.0` but it still doesn't work. Apparently the syntax is incorrect. Please tell me how to fix it.

about autocomplete in the editormrelectronHi team,
my background is mostly in strongly typed languages so autocomplete is always working great.
however i am noticing that autocomplete in the godot editor is a bit lackluster, i get that this is due to the nature of GDScript being a dynamically typed language. but i noticed that if i give concrete types then it works better.
so for the array of dictionaries i tried to use an enum as keys for the expression and text in hopes of being able to access them without typing a string for the key later on, but when i get to the show_text function, it seems like the editor forgot about the enum and doesn't give me hints.
```gdscript
