Creating a Generic Node Component in SpriteKit

After the development of my simple puzzle game, one of the things I wanted to do differently was using a generic Node Component. This would be a component that would do all the scaling, rotating, and positioning in such a way that it could apply to any node type (label, sprite, shape, etc) or even things like particle emitters.

In this post, I’ll create a simple SpriteKit scene with a basic render system and a few simple components to see how this might work.

As I write this, I’m walking the Dale’s Way with nothing but my iPad Pro so this will all be done using the Swift Playgrounds app.

Handling Movement Part 2: Scaling and Z-Positions

In part one, I set up a Movement Component that moved sprites around a space without any regard for the type of scene that they inhabit.

However, many adventure game scenes have some sort of perspective where it’s possible for players to move around an object.

Imagine a game where, say, a character in a trench coat is visiting a square in Lecce, Italy. For some reason, there’s a crate in the middle of it:

Handling Movement Part 1: Getting from A to B

SpriteKit will move that sprite to the given point over the given time without me having to think about it again.

It’s great for many situations. However, there are a few limitations:
