Issue description

When I try to use add_animation in AnimationPlayer, it looks like doesn't have it anymore. Is it changed to others?

Steps to reproduce

$AnimationPlayer.add_animation

Minimal reproduction project (MRP)

animation_player.add_animation(anim_name, anim)

You need to use the AnimationLibrary interface, use get_animation_library

Instructions for this should be added to this page, which arguably makes this an issue for the documentation

May I ask how could I use get_animation_library to add new animation frame?
I tried the following code but look like is wrong:

func setup_animations(data: Dictionary) -> void:
	var anim_library = animation_player.get_animation_library("")

	for anim_name in data["animations"].keys():
		var anim = Animation.new()
		anim.length = data["animations"][anim_name]["frames"].size() * 0.05
		var track_index = anim.add_track(Animation.TYPE_VALUE)

		for frame in data["animations"][anim_name]["frames"]:
			var frame_number = frame["y"] * sprite.hframes + frame["x"]
			var frame_time = frame_number * 0.05
			anim.track_set_path(track_index, String(sprite.get_path()) + ":frame")
			anim.track_insert_key(track_index, frame_time, frame_number)

		anim_library.add_animation(anim_name, anim)

	animation_player.set_animation_library(anim_library)

You can't set it, you just update it directly, see the documentation

No need to call any set method (there isn't one, you can have multiple libraries)

But while the documentation for migration from 3.x should mention this I'd say that you should ask in the other community channels for support 🙂, this is for reporting bugs

Let's keep this open to handle the documentation, or open one on the documentation page
