How to color an SKSpriteNode using colorBlendFactor
Swift version: 5.6
One powerful and under-used feature of SpriteKit is its ability to recolor SKSpriteNodes dynamically. This has almost zero performance impact, which makes it perfect for having multiple-colored enemies or players. It can also be animated, meaning that you could for example make your player flash white briefly when they've been hit by an enemy.
To tint a sprite cyan, use this code:
firework.color = UIColor.cyan
firework.colorBlendFactor = 1If you want to animate the sprite coloring, you'd use this:
let action = SKAction.colorize(with: UIColor.red, colorBlendFactor: 1, duration: 1)TAKE YOUR SKILLS TO THE NEXT LEVEL If you like Hacking with Swift, you'll love Hacking with Swift+ – it's my premium service where you can learn advanced Swift and SwiftUI, functional programming, algorithms, and more.
