  1. Hello all Sorry for my bad english in advance . I have a littel issue with GUI and I want to understand why it works like taht . What is the issue ? I made this function : function vecToLocal (vector, mesh){ var m = mesh.getWorldMatrix(); var v = BABYLON.Vector3.TransformCoordinates(vector, m); return v; } class Raycast { constructor() { } doorOpener(letHit, myGUI, scene){ this.scene = scene; var origin = player.position; var forward = new BABYLON.Vector3( 0, 0, 1,); forward = vecToLocal(forward, player); var direction = forward.subtract(origin); direction = BABYLON.Vector3.Normalize(direction); var length = 1.5; var ray = new BABYLON.Ray(origin, direction, length); var hit = this.scene.pickWithRay(ray); if (hit.pickedMesh == letHit){ if (control.keys.ePress == 1){ scene.beginAnimation(letHit, 0, 40, false); } return myGUI.isVisible = 1 }else { return myGUI.label.isVisible = 0; } } } This function is responsible to opening doors. When player reach a door then GUI shows up which key(E) on keyboard must be pressed for open the door but the GUI only works whith one door . Here is how I call Raycast function : const view = require('./ray.js'); const panelG= require('./gui.js'); class Leves { constructor(scene,camera,followCam,canvas) { this.scene = scene; GuiP = new panelG.GuiP (scene); doo = new view.Ray (); BABYLON.SceneLoader.ImportMesh("", "textury/mapy/", "lvl01.babylon", this.scene,function (newMeshes) { var level_001 = newMeshes[0]; level_001.checkCollisions = true; var door = newMeshes[1]; door.checkCollisions = true; var door2 = newMeshes[2] door2.checkCollisions = true; var openDoor = new BABYLON.Animation("t", "position.z", 25, BABYLON.Animation.ANIMATIONTYPE_FLOAT, BABYLON.Animation.ANIMATIONLOOPMODE_CYCLE); var keys = []; keys.push({ frame: 0, value: 0.45 }); keys.push({ frame:5, value: -1.5 }); keys.push({ frame: 10, value: -3 }); keys.push({ frame: 30, value: -3 }); keys.push({ frame: 35, value: -1.5 }); keys.push({ frame: 40, value: 0.45 }); openDoor.setKeys(keys); door.animations.push(openDoor); door2.animations.push(openDoor); scene.registerBeforeRender(function () { doo.doorOpener (door, GuiP.panel, scene ); /*only animation works*/ doo.doorOpener( door2, GuiP.panel, scene); /* GUI and animation works very good */ }) }) } } I am newbie in babylonjs and javascript too and I want to understand every aspect of babylon js and javascript.
  2. Hiding and showing controls by using isVisible (like a Rectangle in this case) works if the control is not linked to a mesh by linkWithMesh. Once it is attached, the control stays visible. The inner controls (in my case the text inside the rectangle) can be hidden. See the playground https://www.babylonjs-playground.com/index.html#RBP60B#6 lines 35-42.
  3. Hi folks, @Nockawa As well as making use of the fine Castor.js extension for html based UI, I am wanting to add some webgl UI elements using Canvas2d, specifically mesh labels. I have pretty much got to grips with the basics. However one thing I cannot get to work is changing the visibility of elements at run time. For example allowing the user to toggle labels on and off. I have created a silly demo based on the "labels" playground demo. The red sphere has a label. Hitting the 'Z' and 'X' keys moves the label along the viewport x-axis and this works fine. The ''L' key toggles the .isVisible property of the label but has no effect. Note that this property does work at 'create' time. If you change line 5 to default to 'false' then the label will not be displayed. However then hitting 'L' key does not display it. The key events write to the console log so it looks as though the events are triggering. http://www.babylonjs-playground.com/#1RB7WB#20 Am I doing something wrong or is the isVisible not re-read once created? Thanks Richard
  4. Where in blender can we define isVisible true or false? So that exporter from blender to babylon json file include isVisible true or false. Depanding how is define in blender???
  5. I'd like to be able to pick a mesh (instance) when isVisible is false. It seems that isVisible affects pickability for some reason.
