Spawning the Power-up Star at random
We still need to add the Power-p Star into the world. We can randomly spawn a Star every ten encounters to add some extra excitement. Follow these steps to add the Star logic:
Add a new instance of the
Starclass as a constant on theGameSceneclass:let powerUpStar = Star()
Anywhere inside the
GameScene didMovefunction, add the Star as a child of theGameSceneand position it:// Place the star out of the way for now: self.addChild(powerUpStar) powerUpStar.position = CGPoint(x: -2000, y: -2000)
Inside the
GameScene didSimulatePhysicsfunction, update your new encounter code as follows (new code in bold):// Check to see if we should set a new encounter: if player.position.x > nextEncounterSpawnPosition { encounterManager.placeNextEncounter( currentXPos: nextEncounterSpawnPosition) nextEncounterSpawnPosition += 1200 ...
