How to find the coordinates of a click in the Babylon.js scene?

[vinicius.alves]

Hello!

I'm starting in Babylon not long ago, I'm looking for some way to find the coordinates of mouse when there is a click on the canvas. I was able to easily find this for a given object, but not for the scene itself (!?) I do not know what could be wrong, it seems silly, but I have not found the solution...

window.addEventListener('DOMContentLoaded', function () {
    var canvas = document.getElementById('canvas');
    var engine = new BABYLON.Engine(canvas, true); 
            
    var createScene = function () {
        var scene = new BABYLON.Scene(engine);
        scene.clearColor = new BABYLON.Color3.White();

        var box = BABYLON.Mesh.CreateBox("Box",4.0,scene);
        var camera = new BABYLON.ArcRotateCamera("arcCam",
                     BABYLON.Tools.ToRadians(45),
                     BABYLON.Tools.ToRadians(45),
                     10.0,box.position,scene);
                     camera.attachControl(canvas,true);

         var light = new BABYLON.PointLight("pointLight",new BABYLON.Vector3(
            0,10,0),scene);
         light.diffuse = new BABYLON.Color3(1,1,1);

         var onpickAction = new BABYLON.ExecuteCodeAction(
         BABYLON.ActionManager.OnPickTrigger,
         function(evt) {
        
            console.log("(",evt.pointerX,",",evt.pointerY,")");  
        
         });

        //doesn't work (???)
        scene.actionManager = new BABYLON.ActionManager(scene);
        scene.actionManager.registerAction(onpickAction);

        //works fine
        box.actionManager = new BABYLON.ActionManager(scene);
        box.actionManager.registerAction(onpickAction);


    return scene;
}
         
            
  var scene = createScene();
  engine.runRenderLoop(function () {
                scene.render();
            });
 });

Hey,

as I mentioned on StackOverflow, you can still rely on scene.onPointerDownObservable which will give you a PointerInfo object with all that you need
