How to color an SKSpriteNode using colorBlendFactor
Swift version: 5.1
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)SAVE 20% ON iOS CONF SG The largest iOS conference in Southeast Asia is back in Singapore for the 5th time in January 2020, now with two days of workshops plus two days of talks on SwiftUI, Combine, GraphQL, and more!
