Retrofitting the Player class for flight
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.
The Beekeeper
First, clean up the old bee physics tests from the last chapter. Open GameScene.swift
, find didMove
, and locate the bottom two lines; one sets a mass for bee2
, and the other applies an impulse to bee2
. Remove these two lines:
bee2.physicsBody?.mass = 0.2 bee2.physicsBody?.applyImpulse(CGVector(dx: -25, dy: 0))
Updating the Player class
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.swift
and add the following function insidePlayer:
func update() { }
In
GameScene.swift
, add this code at the bottom of theGameScene
class:player.update() } override func update(_ currentTime: TimeInterval) {
Perfect. The
GameScene
class will call thePlayer
class...
