Question

想制作像Paper.io这样的应用。我能够使应用程序沿其路径绘制线条。但是无法创造封闭的道路。

    func action()
    {
    var action = SKAction()
    switch direction {
    case 1:
        action = SKAction.moveBy(x:164,y:0,duration:0.6)
    case -1:
        action = SKAction.moveBy(x:-164,y:0,duration:0.6)
    case 2:
        action = SKAction.moveBy(x:0,y:164,duration:0.6)
    case -2:
        action = SKAction.moveBy(x:0,y:-164,duration:0.6)


    default:
        return
    }

    print("touch start ",posx,posy)

    var repeatAction = SKAction.repeatForever(action)

    ball.run(repeatAction, withKey: "Moving")

    }

我相信你需要在动作旁边创建一个CGPath对象。然后，您可以使用此路径创建具有SKShapeNode属性的fillColor。

let path = CGMutablePath()
// Construct the path e.g. using path.addLine(point:transform:)

let shape = SKShapeNode(path: path)
shape.fillColor = .blue

像Paper.io一样填充颜色
