I want to find all of the child nodes whose names begin with a certain text. I wanted to do it without writing hasPrefix, I thought there was a shorthand way for this. Something along the lines of
let someSquare = SKShapeNode()
someSquare.name = "square1"
let someOtherSquare = SKShapeNode()
someOtherSquare.name = "square2"
self.enumerateChildNodes(withName: "@%square") { stop, in
}
So the actual question I guess should be about that shorthand Objective-C NSString syntax or whatever for strings. I'm not sure what to call it. "@%square" or "%@square"? I remember seeing this somewhere, is this correct syntax?
The SpriteKit documentation includes the page Searching the Node Tree. It shows a syntax for advanced searches.
If I'm reading that documentation correctly, you simply need:
self.enumerateChildNodes(withName: "square[1-9]") { stop, in
}
This will match nodes with names "square1", "square2", ..., "square9".
