Drawing your first sprite
It is time to write some game code—fantastic! Open your GameScene.swift file and find the didMove function. Recall that this function fires every time the game switches to the GameScene. We will use this function to get familiar with the SKSpriteNode class. You will use SKSpriteNode extensively in your game whenever you want to add a new 2D graphic entity.
Tip
The term sprite refers to a 2D graphic or animation that moves around the screen independently from the background. Over time, the term has evolved to refer to any game object on the screen in a 2D game. We will create and draw your first sprite in this chapter: a happy little bee.
