Tinting a Sprite
Provide a color and blend factor to additively color your sprite.
Overview
You can use the color and colorBlendFactor properties to colorize the texture applied to a sprite node. The color blend factor defaults to 0.0, which indicates that the texture should be used unmodified. As you increase this number, more of the texture color is replaced with the blended color. For example, when a monster in your game takes damage, you might want to add a red tint to the character. The following code shows how you would apply a tint to the sprite.
monsterSprite.color = .red
monsterSprite.colorBlendFactor = 0.5
You can also animate the color and color blend factors using actions. The following code shows how to briefly tint the sprite and then return it to normal.
let pulsedRed = SKAction.sequence([
SKAction.colorize(with: .red, colorBlendFactor: 1.0, duration: 0.15),
SKAction.wait(forDuration: 0.1),
SKAction.colorize(withColorBlendFactor: 0.0, duration: 0.15)])
spaceship.run(pulsedRed)
