ios - 如何制作三角形而不是矩形？

Question

我目前正在我的第一款 iOS 游戏中制作一只猫。目前它只是由矩形组成，我真的希望它与三角形一起更漂亮。

我正在使用这段代码来创建矩形，并且效果很好。

func loadAppearance() {
    body = SKSpriteNode(color: UIColor.blueColor(), size: CGSizeMake(63, 40))
    body.position = CGPointMake(0, 2)
    addChild(body)

    let skinColor = UIColor(red: 207.0/255.0, green: 193.0/255.0, blue: 168.0/255.0, alpha:1.0)
    let face = SKSpriteNode(color: goldColor, size: CGSizeMake(40, 25))
    face.position = CGPointMake(30, 0)
    body.addChild(face)

    bodyLine = SKSpriteNode(color: UIColor.magentaColor(), size: CGSizeMake(7, 18))
    bodyLine.position = CGPointMake(-21, 11)
    body.addChild(bodyLine)

    bodyLine2 = bodyLine.copy() as! SKSpriteNode
    bodyLine2.position.x = -11
    body.addChild(bodyLine2)

    let eyeColor = UIColor.whiteColor()
    let leftEye = SKSpriteNode(color: eyeColor, size: CGSizeMake(10, 7))
    let rightEye = leftEye.copy() as! SKSpriteNode
    let pupil = SKSpriteNode(color: UIColor.blackColor(), size: CGSizeMake(5,4))
    let leftEar = SKSpriteNode(color: goldColor, size: CGSizeMake(7, 10))
    let rightEar = leftEar.copy() as! SKSpriteNode
    let mouth = SKSpriteNode(color: UIColor.blackColor(), size: CGSizeMake(15, 5))

    leftEar.position = CGPointMake(-10, 15)
    face.addChild(leftEar)

    rightEar.position = CGPointMake(10, 15)
    face.addChild(rightEar)
}

创建一个等边三角形。

swift 4

let path = UIBezierPath()
path.move(to: CGPoint(x: 0.0, y: 50.0))
path.addLine(to: CGPoint(x: 50.0, y: -36.6))
path.addLine(to: CGPoint(x: -50.0, y: -36.6))
path.addLine(to: CGPoint(x: 0.0, y: 50.0))
SKShapeNode(path: path.cgPath)
