Code seems fine however when i run the simulator in xcode or on my phone and tilt, the player doesnt move. override func update(_ currentTime: TimeInterval) {     if let accelerometerData = motionManager?.accelerometerData {       physicsWorld.gravity = CGVector(dx: accelerometerData.acceleration.x * -50, dy: accelerometerData.acceleration.y * 50)     } Do i need gamescene.sks because i deleted the grid and the file

I deleted the grid on gamescene.sks and i dont know how to get it back. Now my game wont run

Im getting a overridden error for my player and enemy. I made a enemy file and added this code into my gamescene. My enemy only spawns in if i delete my player movement code func spawnEnemy() {       let enemy = Enemy(image: SKSpriteNode(imageNamed: "enemy"))   self.addChild(enemy)   }       override func update(_ currentTime: TimeInterval) {     spawnEnemy()   }

How can i change my objects gravity without having my player fall with it. I added physicsWorld.gravity = CGVector(dx: 0, dy: 0) on my players movement and affectedByGravity on both my object and player. If I change dy to -9.8, my object falls but along with my player

let randomNumber = arc4random_uniform(2) let x: CGFloat = randomNumber == 0 ? 1 : -1 enemy.position = CGPoint(x: (CGFloat(arc4random_uniform(UInt32(UIScreen.main.bounds.width))) * x), y: UIScreen.main.bounds.height) here is my code for enemy spawn, it works but some of my enemies are spawning outside of my screen. What can i change to make them all spawn inside the border
