Panning and support for click event on line in Babylon.js

[Nastro]

Hi @Luaacro 

If you take a multiple tactil application we use two fingers to pan like said @Jose Vicente

[julien-moreau]

so we can have an option to activate only panning or zooming ? Two fingers are already used to zoom if I'm not wrong

Can you distinguish between a 2-finger-slide/swipe and a 2-finger pinch-stretch movement?

I don't know how make this. But maybe you can configure differents movements.

I will try to do this (next step after optimization)

I asked a similar question, and i need to test "FreeCamera" with events

You don't need to distinguish between zoom and panning. In my own camera implementation i also use two fingers for both simultaneously.
It works very well. I use the center of the two fingers as the panning point and distance between the two fingers for the zoom.

As  @iiceman and @Kesshi pointed, I don't want to choose between pan and zoom, I want both if possible

Hello,

+1 for adding panning on mobile device 

[Nastro]

Someone has create event tactil touch like that ? I had no succes...

I tried to implement this.  I edited the ArcRotateCameraPointersInput code to try and get 2-finger touch to pan.  It kinda works but for some reason I can't change direction whilst the fingers are down.  Also, it gets tricky trying to distinguish between pan and zoom.  Any tips to make this work better?

My code is here http://www.babylonjs-playground.com/#RQJ38#2

Search for "I EDITED THIS PART" to get to the code that I added.

Hello,

Always interested by this implementation ! I need it too. I woukd like to help, but I'm not sure I can... I'm going to play with your playground

After a new reading of the topic, it seems that @Kesshi has already worked on it. Maybe if he reads this, he could help us.

@ViBe Yes i sovled that problem for this project:

You can try it on a touch device. But i can't publish the code because its a commercial project ( but in the end its javascript, so ... ).
Its also not so easy to give you some code snippets because i don't rely on any input/event handling from BabylonJs. I implemented my own solution which directly controls a plain BABYLON.TargetCamera.
@ozRocker There is no need to distinguish between zoom and panning. You should perform/calculate both at the same time. If the user doesn't change the distance between the fingers while moving them, no zoom will happen only the panning. Atleast this is what i'm doing in my project.

Thanks for the tip!  I altered my previous playground

The panning is better here.  I just need to make it work with zoom.  I think zoom is too sensitive on touch devices.
