Spawning a circle in a random spot on screen

Question

I\'ve been racking my brain and searching here and all over to try to find out how to generate a random position on screen to spawn a circle. I\'m hoping someone here can he

Answer 1

The problem there is that you scene is bigger than your screen bounds

let viewMidX = view!.bounds.midX
let viewMidY = view!.bounds.midY
print(viewMidX)
print(viewMidY)

let sceneHeight = view!.scene!.frame.height
let sceneWidth = view!.scene!.frame.width
print(sceneWidth)
print(sceneHeight)

let currentBall = SKShapeNode(circleOfRadius: 100)
currentBall.fillColor = .green

let x = view!.scene!.frame.midX - viewMidX + CGFloat(arc4random_uniform(UInt32(viewMidX*2)))
let y = view!.scene!.frame.midY - viewMidY + CGFloat(arc4random_uniform(UInt32(viewMidY*2)))
print(x)
print(y)

currentBall.position = CGPoint(x: x, y: y)
view?.scene?.addChild(currentBall)

self.removeAllChildren()
self.addChild(currentBall)
