Change the color of all nodes in a scene?

Question

So this may seem like a stupid question; however, I'll see if anyone has an answer.

Is there any way to change the color of all nodes in a scene in swift? For example invert all the colors?

I've created a game using SpriteKit and would like to create different themes. Instead of changing every node one by one. I would like to at least do most in one shot. If anyone has any advice that would be greatly appreciated! Thanks!

Inside of the scene you want,

for node in self.children {
 // I used spritenode, but you can add as many nodes with color options as you like.
  guard let snode = node as? SKSpriteNode else { continue }
  snode.color = .blue
}

The inversion function would be a separate question I think :P but something like:

if snode.color == .black { node.color == .white }

But you could probably do this with RGB and math as well.

`SKNode` does not have a `color` property. – 0x141E Jun 10 '17 at 21:06
Perfect this is what I needed! – Matthew Anguelo Jun 10 '17 at 21:10

It's wrong to return on guard fail, you should use the continue statement instead. – Ramy Al Zuhouri Jun 10 '17 at 21:23
@RamyAlZuhouri agreed. I would use an `if` statement. – 0x141E Jun 10 '17 at 21:40

@0x141E Ramy meant that i needed to continue not return, not to use if instead of guard :P – Fluidity Jun 11 '17 at 05:36
