创建SKShapeNode的子类

Question

class ColorRectangle: SKShapeNode {

    var width: CGFloat!
    var height: CGFloat!
    var rectColor: UIColor!

    convenience init(rectOfSize: CGSize, colorOfRectangle rectColor: UIColor) {

        super.init(rectOfSize: rectOfSize)

        self.width = rectOfSize.width
        self.height = rectOfSize.height
        self.rectColor = rectColor

        self.fillColor = rectColor
        self.strokeColor = rectColor
    }

}

无法正确启动初始化程序。 我该怎么办？

Answer 1

尝试像这样更改初始化程序：

class ColorRectangle: SKShapeNode {

    var width: CGFloat!
    var height: CGFloat!
    var rectColor: UIColor!

    convenience init(rectOfSize: CGSize, colorOfRectangle rectColor: UIColor) {

        self.init()

        self.init(rectOfSize: rectOfSize)

        self.rectColor = rectColor

        self.fillColor = rectColor
        self.strokeColor = rectColor
    }

}
