Scenekit - मैं

Question

कैसे दिखा सकता हूं नीचे दिखाए गए कोड के साथ मैं अपने दृश्य में एक गोलाकार करने में सक्षम हूं। नीली पृष्ठभूमि के साथ ... मैं आईओएस में दृश्यकिट के लिए नया हूं। मैं जानना चाहता हूं कि हम उस वस्तु को कैसे स्थानांतरित कर सकते हैं (क्षेत्र को खींचें) दूसरी स्थिति (ड्रॉप) पर।

override func viewDidLoad() { 
    super.viewDidLoad() 
    sceneView = SCNView(frame: self.view.frame) 
    sceneView.scene = SCNScene() 
    self.view.addSubview(sceneView) 


    let groundGeometry = SCNFloor() 
    groundGeometry.reflectivity = 0 
    let groundMaterial = SCNMaterial() 
    groundMaterial.diffuse.contents = UIColor.blueColor() 
    groundGeometry.materials = [groundMaterial] 
    ground = SCNNode(geometry: groundGeometry) 

    let camera = SCNCamera() 
    camera.zFar = 10000 
    self.camera = SCNNode() 
    self.camera.camera = camera 
    self.camera.position = SCNVector3(x: -20, y: 15, z: 20) 
    let constraint = SCNLookAtConstraint(target: ground) 
    constraint.gimbalLockEnabled = true 
    self.camera.constraints = [constraint] 

    let ambientLight = SCNLight() 
    ambientLight.color = UIColor.darkGrayColor() 
    ambientLight.type = SCNLightTypeAmbient 
    self.camera.light = ambientLight 

    let spotLight = SCNLight() 
    spotLight.type = SCNLightTypeSpot 
    spotLight.castsShadow = true 
    spotLight.spotInnerAngle = 70.0 
    spotLight.spotOuterAngle = 90.0 
    spotLight.zFar = 500 
    light = SCNNode() 
    light.light = spotLight 
    light.position = SCNVector3(x: 0, y: 25, z: 25) 
    light.constraints = [constraint] 

    let sphereGeometry = SCNSphere(radius: 1.5) 
    let sphereMaterial = SCNMaterial() 
    sphereMaterial.diffuse.contents = UIColor.greenColor() 
    sphereGeometry.materials = [sphereMaterial] 
    sphere1 = SCNNode(geometry: sphereGeometry) 
    sphere1.position = SCNVector3(x: -15, y: 1.5, z: 0) 


    sceneView.scene?.rootNode.addChildNode(self.camera) 
    sceneView.scene?.rootNode.addChildNode(ground) 
    sceneView.scene?.rootNode.addChildNode(light) 

    sceneView.scene?.rootNode.addChildNode(sphere1) 

}

मी, मैंने कुछ महीनों पहले उद्देश्य के साथ दृश्यकिट की कोशिश की है, यह समाधान को सामान्य बनाने में आपकी मदद कर सकता है। नोड्स के ड्रैग और ड्रॉप के लिए मैंने UIPanGestureRecognizer का उपयोग किया। पैनिंग (चलती) के लिए

// इशारा पहचानकर्ता

UIGestureRecognizer *panGestureRecognizer = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(handlePanFrom:)]; 
[[self view] addGestureRecognizer:panGestureRecognizer]; 

// फिर "handlePanFrom"

- (void)handlePanFrom:(UIPanGestureRecognizer *)recognizer { 


    if (recognizer.state == UIGestureRecognizerStateChanged) 
    { 
     //Getting the new location of the view after pan gesture 
     CGPoint translation = [recognizer translationInView:recognizer.view]; 

     //Converting this translation as per the SpriteKit coordinates 
     translation = CGPointMake(translation.x, -translation.y); 

     //Changing the position of sphere node with the translation 
     CGPoint position = [sphere position]; 
     [sphere setPosition:CGPointMake(position.x + translation.x, position.y + translation.y)]; 

     //Resetting the values of recognizer 
     [recognizer setTranslation:CGPointZero inView:recognizer.view]; 

    } 
    else if (recognizer.state == UIGestureRecognizerStateEnded) 
    { 
     float scrollDuration = 1; 
     CGPoint velocity = [recognizer velocityInView:recognizer.view]; 

     //Taking current position of sphere node 
     CGPoint pos = [sphere position]; 

     //Finding change in position on the basis of velocity and scroll duration 
     CGPoint p = mult(velocity, scrollDuration); 

     //Calculating new position of the sphere 
     CGPoint newPos = CGPointMake(pos.x + p.x, pos.y - p.y); 

     [sphere removeAllActions]; 

     //Action for moving the sprite to the new location 
     SKAction *moveTo = [SKAction moveTo:newPos duration:scrollDuration]; 
     [moveTo setTimingMode:SKActionTimingEaseOut]; 
     [sphere runAction:moveTo]; 
    } 
}
