swift – 使用SKShapeNode在Sprite Kit中绘制虚线

概述I fount this solution but I can’t make it into swift code 这就是我的尝试 var pattern[2]:CGFloat; this var dashed: CGPathRef = CGPathCreateCopyByDashingPath(CGPathCreateCopyByDashingPath(path, transform, ph I fount this solution but I can’t make it into swift code

这就是我的尝试

var pattern[2]:CGfloat; this var dashed: CGPathref = CGPathCreatecopyByDashingPath(CGPathCreatecopyByDashingPath(path,transform,phase,lengths,count);var myShapeNode: SKShapeNode!;        var CGPathCreatecopyByDashingPath:CGPathref;

解决方法 这是你在swift中绘制虚线的方法.您可以根据需要更改参数.

let bezIErPath = UIBezIErPath()let startPoint = CGPointMake(0,250)let endPoint = CGPointMake(450,250)bezIErPath.movetoPoint(startPoint)bezIErPath.addlinetoPoint(endPoint)var pattern : [CGfloat] = [10.0,10.0]let dashed = CGPathCreatecopyByDashingPath (bezIErPath.CGPath,nil,pattern,2)var shapeNode = SKShapeNode(path: dashed)shapeNode.position = CGPointMake(100,100)self.addChild(shapeNode)
