Support Godot 4

[lunarcloud]

I know the 4.0 alpha is hot off the presses, but the inkGD plugin doesn't yet work with it, at least not on my autoconverted project, and the new text / font improvements make it really appealing for ink storytellers.

Looks like a lot of it is gdscript updates -

• Need optional typing added to the top-of-file variables to catch every error better.
• "@tool" and "@onready" instead of "tool" and "onready"
• stricter whitespace enforcement (use only tabs or spaces for indentation, not both)
• Changed signal syntax: now "obj.funcA.connect(funcB)"
• "get_icon" renamed "get_theme_icon"
• "OS.execute" rearranged the arguments
• "PoolStringArray" doesn't exist, maybe replaced by "PackedStringArray"
• "preload("").instance()" replaced by "preload("").instantiate()" ?
• Something happened to the "focus_*" signals, maybe replaced by "text_changed" etc signals
• "add_font_override(x)" has been changed
• "continue" is a keyword now, and cannot be used as function name

Okay, that's probably all the investigation into what's changed I can do.
Yes, I know it's a lot.
Yes, I'm aware this'll need to be completely forked so there's a gd3 and gd4 version.

Hey @lunarcloud, thanks for investigating this!

I'm going to create a PR to track what changes are needed for the migration. I don't plan to work on it before the first beta though, as I'm waiting for the feature freeze.

Need optional typing added to the top-of-file variables to catch every error better.

We need to be careful about that one. Some types are deliberately not enforced because GDScript doesn't support optionals. In particular, Array, String and Dictionary are not nullable while upstream often test for their nullability.

stricter whitespace enforcement (use only tabs or spaces for indentation, not both)

That's great if the editor warns about them! If there's still spaces lying around, they are the remnants of a bygone era.

Ah, with typing, where I can't add it, I leave a comment explaining why / what it should be for myself. I've also experienced moments where it's not ok, particularly Arrays.

Progress tracked in #56, I've combined our findings!

Does the latest release (0.5.0 as of today) currently have Godot 4 support?
The issue is open (plus the releases I've browsed through don't mention Godot 4), but the PR is closed, so I'm unsure if there is support already.

Thanks in advance!

The godot4 branch supports Godot 4 and Ink 1.1.1
I'm currently working with it on a project and everything seems to be working !

Hello, unfortunately the branch Godot 4 seem to not work with Godot 4.2 for me.

Adding the Godot4 branch to new Godot 4.2 project results in following errors:

The __InkRuntime is added to the project autoload by enabling the project, but trying to add InkPlayer node to scene results in following errors:

   Cannot get class ''.
  editor/editor_data.cpp:581 - Parameter "p_object" is null.
  editor/scene_tree_dock.cpp:2447 - Parameter "child" is null.

We've upgraded to Godot 4.2 and it works.
You might need to reload the project once upon enabling the plugin.
