The tutorial code error in the Godot introductory documentation causes the enemy animation to fail to play properly.

In the "Getting Started - Your First 2D Game - Directory - Creating Enemies - Enemy Script" section of the code, the line `$AnimatedSprite2D.animation = mob_types.pick_random()` only randomly selects the enemy's movement state but does not play the enemy's animation. None of the subsequent code addresses this issue, which causes users following the documentation to end up with enemies that move along their paths but do not play animations. The above line of code should perhaps be changed to `$AnimatedSprite2D.play(str(mob_types.pick_random())).`
