This video covers 2D graphics in Godot 3. We start by looking at the 2D editor tools then move on to create a Sprite, including covering the process of importing textures into the Godot engine. We then look at scripting Sprite objects, covering tasks like pivot points, translating, rotating, and scaling. We then move on to AtlasTextue, a single texture with multiple images. We then create a script illustrating how to use a sprite sheet, including creating a timer to flip between animation frames. Finally, we look at using the AnimatedSprite node, including code to control switching animations.
