[4.0-Beta2] - Setting Screen Stretch Mode From GDScript Code?

JeZxLee

Hi,

Running 4.0 Beta 2 on Linux Mint 21 Cinnamon.
How to set screen stretch mode from GDScript code using new Godot 4.0 Beta 2?

We are trying to port code from 3.5 to 4.0:

if (VisualsCore.KeepAspectRatio == 1):
get_tree().set_screen_stretch(SceneTree.STRETCH_MODE_VIEWPORT, SceneTree.STRETCH_ASPECT_KEEP_WIDTH, Vector2(1024, 640) , 1)
elif (VisualsCore.KeepAspectRatio == 0):
get_tree().set_screen_stretch(SceneTree.STRETCH_MODE_VIEWPORT, SceneTree.STRETCH_ASPECT_IGNORE, Vector2(1024, 640) , 1)

Have below code now, but it does not run with 2 errors:

# Invalid get index 'CONTENT_SCALE_MODE_VIEWPORT' (on base: 'SceneTree').
get_tree().set_content_scale_mode(SceneTree.CONTENT_SCALE_MODE_VIEWPORT)

if (VisualsCore.KeepAspectRatio == 0):
	get_tree().set_content_scale_aspect(SceneTree.CONTENT_SCALE_ASPECT_KEEP_WIDTH)
elif (VisualsCore.KeepAspectRatio == 1):
# Invalid get index 'CONTENT_SCALE_ASPECT_IGNORE' (on base: 'SceneTree').		
	get_tree().set_content_scale_aspect(SceneTree.CONTENT_SCALE_ASPECT_IGNORE)

Spent a bit of time figuring out what happened here, turns out all the properties relating to handling tree-specific displays were moved to a Window class which makes a lot more sense.
See: https://docs.godotengine.org/en/latest/classes/class_window.html

You can still access these properties by using the SceneTree's root property which references the Window instance storing all these properties that were previously in the SceneTree.
Albeit under slightly different names.
See: https://docs.godotengine.org/en/latest/classes/class_scenetree.html#class-scenetree-property-root

TLDR.
content_scale_aspect is the new stretch mode property.
and,
get_tree().get_root().set_content_scale_aspect(Window.CONTENT_SCALE_ASPECT_KEEP) is how you set it.
