This is what AtlasTexture is for: a texture resource which is an individual sprite cut-out from a larger sprite sheet (or atlas). After creating the AtlasTexture in code, assign its atlas property to the loaded sprite sheet, and its region property to the Rect2 with the coordinates of the upper left coordinate of the sprite in the spritesheet, along with the sprite size.
Here is a code example of an AnimatedSprite, SpriteFrames and one AtlasTexture for each frame, all created through code:
extends Node2D
func _ready() -> void:
var anim_sprite := AnimatedSprite.new()
var sprite_frames := SpriteFrames.new()
sprite_frames.add_animation("idle")
sprite_frames.set_animation_loop("idle",true)
var texture_size := Vector2(64,64)
var sprite_size := Vector2(32,32)
var full_spritesheet : Texture = load("res://icon.png")
var num_columns : int = int(texture_size.x/sprite_size.x)
for x_coords in range(num_columns):
for y_coords in range(int(texture_size.y/sprite_size.y)):
var frame_tex := AtlasTexture.new()
frame_tex.atlas = full_spritesheet
frame_tex.region = Rect2(Vector2(x_coords,y_coords)*sprite_size,sprite_size)
sprite_frames.add_frame("idle",frame_tex,y_coords*num_columns+x_coords)
anim_sprite.frames = sprite_frames
add_child(anim_sprite)
anim_sprite.position = Vector2(32,32)
anim_sprite.play("idle")
