We need to perform a few quick setup tasks before we can react to player input. We will remove some of our older testing code and add a physics body to the Player class.
First, clean up the old bee physics tests from the last chapter. Open GameScene.swift, find didMoveToView, and locate the bottom two lines; one sets a mass for bee2, the other applies an impulse to bee2. Remove these lines.
We need to give the Player class its own update function. We want to store player-related logic in Player, and we need it to run before every frame.
Open
Player.swiftand add the following function insidePlayer:func update() { }In
GameScene.swift, add this code at the bottom of theGameSceneclass:override func update(currentTime: NSTimeInterval) { player.update() }
Perfect. The GameScene class will call the player class update function on every update.
