Switf Sprite remove NODE

Swift Sprite Kit

Remove Node, if Node leave View

set

var newSprit = SKSpriteNode()

create function for Node create

func createNewSprite(point : CGPoint) {
        newSprit = SKSpriteNode(color: UIColor.orange, size: CGSize(width: 50, height: 50))
        newSprit.physicsBody = SKPhysicsBody(rectangleOf: CGSize(width: 50, height: 50))
        newSprit.position = point
        self.addChild(newSprit)
}

on override func update(_ currentTime: TimeInterval) add new code

self.enumerateChildNodes(withName: String, using: (SKNode, UnsafeMutablePointer) -> Void)

check your View first, if your View setup by Portrait, you may check your node leave view by point X if your View setup by Landscape, you may check your node leave view by point y

Code:

self.enumerateChildNodes(withName: "TEST") { (node : SKNode, nil) in
            if node.position.x < -320 || node.position.x > 320 {
                print("remove node")
                node.removeFromParent()
            }
        }

on the code we know

enumerateChildNodes(withName: "???")

so we need give our node a name

How

back to function createNewSprite, and add new line

newSprit.name = "TEST"

this sample set the name is TEST, so we can back to

enumerateChildNodes

and write the name
