Hi,

I would like to know if this code is correct for the time management in BabylonJS (time-fps independence)

var time=0;var t1;var vitesseRotation=10;var canvas = document.getElementById("renderCanvas");var engine = new BABYLON.Engine(canvas, true);var scene = new BABYLON.Scene(engine);var camera = new BABYLON.ArcRotateCamera("Camera",0, Math.PI/4, 15, new BABYLON.Vector3(0, 0, 0), scene);var light = new BABYLON.PointLight("Omnidir", new BABYLON.Vector3(10, 0, 10), scene);var maBox= new BABYLON.Mesh.CreateBox("box_1",5,scene);scene.registerBeforeRender(function(){	t1=new Date().getTime()/1000	maBox.rotation.y=vitesseRotation*time;});engine.runRenderLoop(function () {    scene.render();    time=time+((new Date().getTime()/1000)-t1);});

thank you for your help

 

PS : I've problem with "getLastFrameDuration();" : lag in my scene

other solution :

var time=0;var vitesseRotation=3;var canvas = document.getElementById("renderCanvas");var engine = new BABYLON.Engine(canvas, true);var scene = new BABYLON.Scene(engine); var camera = new BABYLON.ArcRotateCamera("Camera",0, Math.PI/4, 15, new BABYLON.Vector3(0, 0, 0), scene);var light = new BABYLON.PointLight("Omnidir", new BABYLON.Vector3(15, 0, 10), scene);var maBox= new BABYLON.Mesh.CreateBox("box_1",2,scene);scene.registerBeforeRender(function(){	time=time+(1/BABYLON.Tools.GetFps());	maBox.rotation.y=vitesseRotation*time;});engine.runRenderLoop(function () {    scene.render();});

the good way ?
