Change Texture In Scene Editor Programmatically

Question

I've added a color sprite, named "arm" to my Scene Editor but for a bunch of reasons I need to access that color sprite and change the texture programmatically. Another way of stating my goal, I want to link the node to my GameScene swift file and change texture using a texture from an array. Does anyone know how to do this?

Answer 1

First things first, you want to link the sprite node from your GameScene.sks file to your GameScene.swift file.

To do this, in GameScene.swift near the top (under the "class GameScene: SKScene {") use this:

var armNode: SKSpriteNode?

In your didMove(to view:) section do this:

armNode = childNode(withName: "arm") as? SKSpriteNode

Now 3 different ways to change the color/texture of the SKSpriteNode depending on what you are doing:

armNode.colour = UIColor.red

armNode.texture = SKTexture(imageNamed: "your arm image here")

armNode.texture = textureArray[2]

The 3rd version uses a texture from an array of textures
