• NSTextField with suggestions shown in dropdown

  I am trying to implement autocomplete with an NSTextField where the user will type in some string and suggestions will be fetched from an API to be displayed under the text field. Optionally display a progress indicator inside the text field. So far I have designed the UI in Xcode IB and hooked the event to get the text change event.

      public class UserTextFieldDelegate: NSTextFieldDelegate
      {
          public NSTextField Username { get; set; }
          public UserTextFieldDelegate()
          {
          }
          public UserTextFieldDelegate(NSTextField username)
          {
              this.Username = username;
          }
          public override void Changed(NSNotification notification)
          {
              Console.WriteLine(Username.StringValue);
          }
      }
  

  The API will return a list of objects which I need to bind with the datasource of autocomplete list. How do I achieve this in Xamarin.Mac?
• Regaining the recognized AugmentedImage and Plane when the tracking lost

  We are using ARCore to create the following experience using S8+ : 1 - The user detect an image and create an Anchor as a parent to a 3D object. 2 - This 3D object will move far from it's Anchor position to a distance max of 100 Meters and the User (Camera) will follow it .

  When the tracking is lost, we lose all the Anchors and the 3D objects attached to it. How can we regain the recognized AugmentedImage and Plane when the tracking is lost and the Camera/User is far from the original coordinates of the Image knowing that we can't tell the user to detect again the Image.

• Why when changing transition between two states in animator it's not changing it slow and smooth?

  It does change the states and play the animation but it's doing it at once there is no delay slow motion when changing between the states.

  Grounded is > HumanoidIdle

  And a transition from Grounded to Walk. This part is working fine the changing between the Grounded and Walk is slowly and smooth.

  The Walk parameter is a bool type.

  

  The problem is the transition from the Walk to Use. It's changing from Walk to Use at once immediately there is no delay/slow motion.

  

  This is the script I'm using to trigger the states:

  using System.Collections;
  using System.Collections.Generic;
  using UnityEngine;
  using UnityEngine.Playables;
  
  public class SpaceshipCutscene : MonoBehaviour

      public Transform console;
      public Camera FPSCamera;
      public Camera mainCamera;
      public Animator[] anim;
      public float rotationSpeed = 3f;
  
      private bool moveNpc = false;
  
      // Use this for initialization
      void Start()
      {
  
      }
  
      private void Update()
      {
          if (moveNpc)
          {

              Vector3 dir = player.position - npcs[0].position;
              dir.y = 0; // keep the direction strictly horizontal
              Quaternion rot = Quaternion.LookRotation(dir);
              // slerp to the desired rotation over time
              npcs[0].rotation = Quaternion.Slerp(npcs[0].rotation, rot, rotationSpeed * Time.deltaTime);
  
              float dist = Vector3.Distance(npcs[1].position, console.position);
              if (dist < 4f)

              }

              dirToComputer.y = 0;
              Quaternion rot1 = Quaternion.LookRotation(dirToComputer);
              npcs[1].rotation = Quaternion.Slerp(npcs[1].rotation, rot1, rotationSpeed * Time.deltaTime);

• Three js RayCast between two object in scene

  I know how raycast object in scene when click on mouse, but now i need to know if two object in scene can raycast each other.

  This is, i load a 3D Object in scene for example Two Rooms in OBJ object, then i add three mesh box in some points, for example two point on first room and one point on second room.

  Then two points on first room can raycast each other(have direct vision), but two point for first room can't raycast point on second room.(they don't have vision through room wall).

  I attached code used for load scene and points, any sugestion hwo to do?

  //LOAD MAIN 3D OBJECT
      var objLoader = new THREE.OBJLoader();
          objLoader.setMaterials(materials);
          objLoader.setPath('./asset/3d/');
          objLoader.load("model01.obj", function(object){
              var mesh = object.children[0];
              mesh.castShadow = true;
              mesh.receiveShadow = true;
  
              mesh.rotation.x = Math.PI / 2;
  
              var box = new THREE.Box3().setFromObject( object )
              var ox = -(box.max.x + box.min.x) / 2;
              var oy = -(box.max.y + box.min.y) / 2;
              var oz = -(box.max.z + box.min.z) / 2;
              mesh.position.set(ox, oy, oz);
  
              _scene.add(mesh);
  
              render();
  
              setTimeout(render, 1000);
  
          }
  
  //LOAD count_points inside scene
  for(var i=0;i<cta_points;i++){
      var c_r = 2;
      var c_geometry = new THREE.BoxBufferGeometry( c_r, c_r, c_r );
      var c_material = new THREE.MeshLambertMaterial( { color: new THREE.Color("rgb("+(40 +   30)+", 0, 0)"),opacity: 0.0,
                          transparent: true} );                       
      var c_mesh = new THREE.Mesh( c_geometry, c_material );
      var position = get_positions(i);
      c_mesh.position.copy(position);

• Raycasting walls arent drawed equally wide

  I am working on a raycaster and followed this tutorial: https://dev.opera.com/articles/3d-games-with-canvas-and-raycasting-part-1/

  My questions is about a Bug which draws / calculates Walls in diffrent Width depending on where on the canvas its drawn (so how big the ray angle is to the players point of direction (center view)): The Walls in drawn in the middle (1.) are small, but those on the left or right (2.) side of the screen are drawn wider. Its easiest to understand when you look at the image. I think I just got the Math wrong, maybe rounded up somewhere I shouldnt but I havent found it yet or could think of any reason this error accures. Its made in a HTML Canvas using JavaScript.

  

  In my first function I am sending out a ray for each x pixel of my canvas:

  let resolution = Math.ceil(canvas.width / this.resolution); //canvas width = 1600, resolution = 1
  let id = 0;
  
      for (let x = 0; x < resolution; x++) {
          let viewDist = (canvas.width / this.resolution) / Math.tan((this.fov / 2)); //fov 90 in rad
          let rayx = (-resolution / 2 + x) * this.resolution;
          let rayDist = Math.sqrt(rayx * rayx + viewDist * viewDist);
          let rayAngle = Math.asin(rayx / rayDist);
  
          let wall = this.castWall(this.pod * Math.PI / 180 + rayAngle);
          this.drawWall(x, wall);
      }
  

  But I dont think theres anything wrong here. In the second function I am castinbg each ray and giving back the distance to the hit wall. My blocks / walls are 50 wide. My map is stored in and 2D number Array -> this.map.grid, this.map.width holds how many block there are in x direction, this.map.height holds the count in y direction.

  castWall(angle) {
      const PI2 = Math.PI * 2;
  
      angle %= PI2;
      if (angle < 0) {
          angle += PI2;
      }
  
      let right = angle > PI2 * 0.75 || angle < PI2 * 0.25;
      let up = angle < 0 || angle > Math.PI;
  
      let sin = Math.sin(angle);
      let cos = Math.cos(angle);
  
      let dist = 0;
      let textureX;
      let texture;
  
      let slope = sin / cos;
      let dXVer = right ? 1 : -1;
      let dYVer = dXVer * slope;
  
      let px = this.x / 50;
      let py = this.y / 50;
  
      let x = right ? Math.ceil(px) : Math.floor(px);
      let y = py + (x - px) * slope;
  
      while (x >= 0 && x < this.map.width && y >= 0 && y < this.map.height) {
          let wallX = Math.floor(x + (right ? 0 : -1));
          let wallY = Math.floor(y);
  
          if (this.map.grid[wallY][wallX] > 0) {
              dist = Math.sqrt(Math.pow(x - px, 2) + Math.pow(y - py, 2));
              texture = this.map.grid[wallY][wallX];
              textureX = (y * 50) % 50;
  
              if (right) {
                  textureX = 50 - textureX;
              }
              break;
          }
          x += dXVer;
          y += dYVer;
      }
  
      slope = cos / sin;
  
      let dYHor = up ? -1 : 1;
      let dXHor = dYHor * slope;
  
      y = up ? Math.floor(py) : Math.ceil(py);
      x = px + (y - py) * slope;
  
      while (x >= 0 && x < this.map.width && y >= 0 && y < this.map.height) {
          let wallY = Math.floor(y + (up ? -1 : 0));
          let wallX = Math.floor(x);
  
          if (this.map.grid[wallY][wallX] > 0) {
              let distHor = Math.sqrt(Math.pow(x - px, 2) + Math.pow(y - py, 2));
  
              if (dist === 0 || distHor < dist) {
                  dist = distHor;
                  texture = this.map.grid[wallY][wallX];
                  textureX = (x * 50) % 50;
  
                  if (up) {
                      textureX = 50 - textureX;
                  }
              }
              break;
          }
          x += dXHor;
          y += dYHor;
      }
  
      return {
          distance: dist,
          texture: texture,
          textureX: textureX
      };`
  

  Ive also tried raycasting with other algorithms (Bresenham & DDA) but I never got them really to work. This is the only one which works for me. If you have any questions about the code feel free to ask.
• Aframe raycaster not hitting object

  I'm trying to add a click handler to a 3d model in aframe. Only a few small regions in the model trigger the click event. Can someone help me figure out why the raycaster is not hitting the object most of the time? I've added a snippet of my Angular2 template with the aframe scene. I'm using Aframe version 0.7.1.

  <div
    #sceneContainer
    id="sceneContainer"

    [ngClass]="{invisible: !config['model']}"
    style="width: 100%; height:100%; cursor:pointer;">

  Any help would be appreciated!

  UPDATE:

  I've found the cause of the issue. See aframe embeded scene with cursor mouse ray-origin

  Apparently mayognaise has updated the mouse-cursor-component to use the canvas element for raycasting. Can someone show me how to change my code to use the mouse-cursor-component?
• BehaviorSubject is executed more than once

  I am using angular 4 for my app and I use behaviorSubject to communicate between component, everythings were working fine

  Here is my code:

  export class Globals {
  loadStudentsByClass: BehaviorSubject<string> = new BehaviorSubject<string>(null);
  }
  
  export class ClassComponent implements OnInit {
  selectNewClass() {
      console.log('About to select new class', this.selectedClass);
      this.globals.loadStudentsByClass.next(this.selectedClass); 
      this.globals.changeClassBehavior.next(true);
      this.router.navigateByUrl('');
    }
  }
  
  export class StudentComponent implements OnInit {
      this.globals.loadStudentsByClass.subscribe(value => {
            if (!isNullOrUndefined(value) && this.selectedClass !== value) {
              console.log('loadStudentsByClass=> home');
              this.loadStudentsByClass(this.selectedClass);
            }
          });
  }
  

  So, I have the component ClassComponent who triggers the StudentComponent to call the function loadStudentsByClass.

  This is the only place where I call this behavior subject, but I find my behavior Subject emitted more than once

  The problem is why behaviorSubject execute loadStudentsByClass more than once although this.globals.loadStudentsByClass.next(this.selectedClass); is called only one time

  By the way the number of execution depends on the numbers of views I visited in the application
• Rxjava combineLatest - why is BiFunction called twice when only one subject changed?

  I wrote a simply example in hopes someone can help me understand this code and why its printing the text in the Bifunction twice:

   var subject1: BehaviorSubject<String>? = null
      var subject2: BehaviorSubject<String>? = null
  
  
  
  
  
     override fun onCreate(savedInstanceState: Bundle?) {
          super.onCreate(savedInstanceState)
          setContentView(R.layout.activity_main)
          Log.v("mytag", "oncreate called now")
          subject1 = BehaviorSubject.createDefault("hello")
          subject2 = BehaviorSubject.createDefault("goodbye") //not subscribed to
  
  
          subject1?.subscribe { Log.v("subject1 it1", it) }
  
  
          btn.setOnClickListener {
              subject1?.onNext("hello btnclicked" + Random().nextInt(9000))
  
              ObservableCombineLatest.combineLatest(
                      subject1,subject2, BiFunction<String,String,String>
              { t1, t2 -> "biFun call" }).
                      subscribe { msg-> Log.d("mytag","combined latest update: $msg")}
          }
      }
  
  }
  

  when i click the button on the first try, this is the output:

   07-13 00:55:09.124 10559 10559 D mytag   : combined latest update: biFun call
  07-13 00:55:09.130 10559 10559 D mytag   : combined latest update: biFun call
  

  but why ? only one subject has changed, thats subject1 variable. when i click the button its invoking onNext which starts an emission. Why is it printing twice ? i am expecting since subject2 is never used it will not fire.
