So I'm trying to use SpriteKit to make the background of my game. The walls have alpha 1.0, and the safe area alpha 0 and fully transparent. (e.g. a big black square with a smaller transparent square in the middle of it). Yet sprite kit always assume the entire image is either fully opaque or fully transparent. That defies its purpose isn't it? Is there a way to make this work?
Why is SKPhysicsBody not picking up alpha?! SpriteKit for a WatchOS game.
Your application must fill the entire screen with content. Consider using a simple SKShapeNode to provide a black background behind your game’s main play area.
