var posinonY:Float = Float(y) + Float(pipeDown.size.height) + Float(verticalPipeGap)
pipeDown.position = CGPointMake(0.0, Float(posinonY))

I get this error:

"NSNumber' is not a subtype of 'CGFloat'"

Why?

Edit:

CGFLoat need double type

pipeDown.position = CGPointMake(0.0,  Double(posinonY))

this is ok.

Use CGFloat(number) instead of Float(number)

pipeDown.position = CGPointMake(0.0, CGFloat(posinonY))
