我正在使用ARKit制作游戏,我想要一个hud,所以我尝试了这个:
let skScene = SightScene(size: self.view.bounds.size)
self.sceneView.overlaySKScene? = skScene
self.sceneView.overlaySKScene?.scaleMode = .aspectFill
其中sceneView是:
var sceneView: ARSCNView!
SightScene是:
class SightScene: SKScene {
var circle: SKShapeNode!
override init(size: CGSize) {
super.init(size: size)
circle = SKShapeNode(circleOfRadius: 40)
circle.position = CGPoint(x: size.width/2, y: size.height/2 )
circle.zPosition = 100
circle.name = "Sight"
circle.strokeColor = SKColor.black
circle.glowWidth = 10.0
circle.fillColor = SKColor.orange
circle.physicsBody = SKPhysicsBody(circleOfRadius: 40)
circle.physicsBody?.isDynamic = true
self.addChild(circle)
}
required init?(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
}
我希望形状节点在屏幕中心生成。请有人帮帮我吗?
修改
我这样做了:
print(skScene)
我收到了skScene信息
但是当我这样做时:
print(self.sceneView.overlaySKScene)
我发现没有,为什么?
