Change zoom to mouse location to instead use right click

[mawa]

Hi,

Let me see… For:

@Silver

change input for the zoomToMouseLocation from wheel scroll to just a right click.

Hum, don’t think this has ever been implemented. Although suggested at some point.
I believe it still works only with the mouse-wheel?! Others to confirm. Here’s for my current ref:

How to set zooming based on the position of cursor in mouse-wheel?

AFAIK, zoomToMouseLocation is only applicable to the mouse wheel but I could see it potentially being adapted for use with the pinch zoom gesture. I could see this being a good feature to request but it may take a while before it gets implemented. If it’s needed or wanted sooner than later, I could also recommend to take a crack at implementing it and putting it in a pull request.

Luckely, there are other ways . The simple picking method will work AS LONG AS there’s a mesh (a plane, something, anything) to pick from. If you pick in just the blank scene, it’s not gonna work (because there’s no reference in the 3D space.

Here’s a quickly modified PG around this and below the reference link:

I can't get my code to find out exactly where I click and place a ball

Hey @spookelix, so if you’re looking for the X,Y,Z vector for a point that you click in a 3D space, you’ll need a PickingInfo object. Off of the top of my head, you can get this by doing something like this: scene.onPointerObservable.add((eventData) => { // If there's a hit on some mesh if (eventData.pickInfo.pickedPoint) { // Do something with the pickedPoint vector } ); In this modified form of your PG (zaxis | Babylon.js Playground), depending on where you click on the …

Next, for…

@Silver

when you right click it instantly zooms to that location

…and then what? what happens when you left-click, when you release click or if you attempt to use the mouse-wheel? For all of that, you need to

1. define behavior
2. customize inputs (checkout the doc starting here for more info on this part) - or check the forum for something like #mouse camera #inputs

Finally, for…

@Silver

I would really prefer only the alpha and beta values of the camera to be affected

Well, I’m afraid this won’t work with the arcRotateCamera. This camera works with a target for a start with, so you just have to set a target. The distance/zoom is generally the radius. However you can also zoomIn or change the fov. However, changing the fov will also give a different perspective. Or providing you would actually select a mesh (and not a just a point), you could also attempt to go with the ‘camera.useFramingBehavior’ which will autozoom on the boundingBox of the selected mesh/target.

Well, I hope this will help a little and meanwhile, have a great sunday

Edit: Just a quick adding. Admitting you would choose to pick a mesh instead of a point.

Just very roughly done, based on this PG, part of the doc. You would still need to add the custom mouse pointer input behavior.
