Code Snippet: SpriteKit Spring / Bounce (Simple)

A very simple code to produce an almost spring effect to a node. Play around with dropHeight and bounceFactor to get desired effect.

SKAction* bounce = [SKAction sequence:@[
[SKAction moveByX:0 y:dropHeight*bounceFactor duration:0.1f],
[SKAction moveByX:0 y:-dropHeight*bounceFactor duration:0.1f],
[SKAction moveByX:0 y:dropHeight*bounceFactor/2 duration:0.1f],
[SKAction moveByX:0 y:-dropHeight*bounceFactor/2 duration:0.1f]]];
