You may have noticed that Pierre Penguin quickly falls to the ground as soon as you launch the game, which is not much fun. Instead, we can launch Pierre into a graceful looping arc as the game starts to give the player a moment to prepare for flight. To do so, open Player.swift and add this code at the bottom of the spawn function:
// Grant a momentary reprieve from gravity:
self.physicsBody?.affectedByGravity = false
// Add some slight upward velocity:
self.physicsBody?.velocity.dy = 50
// Create a SKAction to start gravity after a small delay:
let startGravitySequence = SKAction.sequence([
SKAction.waitForDuration(0.6),
SKAction.runBlock {
self.physicsBody?.affectedByGravity = true
}])
self.runAction(startGravitySequence)
