I was wondering if there was a way to create a doorway in gameScene.sks. If Arnie walked into the door way could it load another .sks file where he could walk around and explore that tileMap then go back to the door way to load gameScene.sks.
@ryguy - the code from this tutorial https://www.raywenderlich.com/158961/introduction-spritekit-scene-editor does just that.
Set up a doorway node and check for physics contact. When there is contact, transition to a new scene.
