当我创建使用雨燕语言的新场景套件游戏,已经有一些来赋予这个结果:
我想关闭该照明立方体环境光,但我不明白如何要做到这一点,因为没有任何光明确附加到任何节点。如何关闭Scene Kit中的环境光(使用Swift)?
她是游戏视图控制器代码:
import SceneKit
import QuartzCore
class GameViewController: NSViewController {
@IBOutlet var gameView: GameView
override func awakeFromNib(){
// create a new scene
let scene = SCNScene()
// create and add a camera to the scene
let cameraNode = SCNNode()
cameraNode.camera = SCNCamera()
scene.rootNode.addChildNode(cameraNode)
// place the camera
cameraNode.position = SCNVector3(x: 0, y: 0, z: 2)
// create and add a 3d box to the scene
let boxNode = SCNNode()
boxNode.geometry = SCNBox(width: 1, height: 1, length: 1, chamferRadius: 0.02)
scene.rootNode.addChildNode(boxNode)
// create and configure a material
let material = SCNMaterial()
material.diffuse.contents = NSImage(named: "texture")
material.specular.contents = NSColor.whiteColor()
material.specular.intensity = 0.2
material.locksAmbientWithDiffuse = true
// set the material to the 3d object geometry
boxNode.geometry.firstMaterial = material
// animate the 3d object
let animation: CABasicAnimation = CABasicAnimation(keyPath: "rotation")
animation.toValue = NSValue(SCNVector4: SCNVector4(x: 1, y: 1, z: 0, w: M_PI*2))
animation.duration = 5
animation.repeatCount = MAXFLOAT //repeat forever
boxNode.addAnimation(animation, forKey: "")
// set the scene to the view
self.gameView!.scene = scene
// allows the user to manipulate the camera
self.gameView!.allowsCameraControl = true
// show statistics such as fps and timing information
self.gameView!.showsStatistics = true
// configure the view
self.gameView!.backgroundColor = NSColor.blackColor()
}
}
我已经移植你的代码到ObjC并在iOS SceneKit模板中替换,我只是将NSImage和NSColor更改为UIImage和UIColor,并且渲染了该多维数据集,但没有纹理或灯光,你有什么想法问题可能是?我猜测代码正在加载模板中的默认纹理。我是否需要为代码添加灯光? – rraallvv
