Panning the camera moves the whole scene except for the mesh that the camera is focused on.

[MacSkelly]

So I'm not sure if this is a bug or maybe I've just not configured the camera correctly. I have a scene that's the interior of a building and the interior is made of a bunch of room meshes joined together. I have it so that when you click on a room the camera sets that room mesh as its target. If I try to pan the camera(ctrl and mouse drag) after clicking on a room the whole interior pans except for the room that I clicked on which stays in the centre of the screen, separated from the rest of the rooms. Any way to remedy this?

I'm using an ArcRotateCamera by the way.

Example of what I mean: http://www.babylonjs-playground.com/#18KHF6#0

Click on sphere2 and then pan the camera (ctrl and mouse drag).

Hi MS, good to see you again.

   Yeah, something is toasted, somewhere, here.  Rodents... chewing on the framework, I suspect.

I tried two different methods of keeping sphere2.position locked-in-place, and failed.

In my past experience, when an ArcCamera has a set target, control-dragging got disabled.

See:  https://github.com/BabylonJS/Babylon.js/commit/725298b717773e271b1256bca45a96db8159cdf2#diff-c5e36d2c529e0623cfb58b616c79943fL15173

Looks like some work on ArcCam targets happened within the last day.  I think Deltakosh will have words about this... in < 4 hours from now.  Thanks for the report and PG.

Thanks for the reply.

I think in the meantime I'll add an eventListener on CTRL that resets the camera target when pressed.

Here is one way to fix the issue:

I added the var _panning and lines 11-16;

Hi, what it actually does is moving the mesh you are focused along with the camera ;-)

[Wingnut]

That is correct, aW.   A-weird-o issue, eh?   hmm.  *scratch scratch*

Mr. @Deltakosh, would you assist with this, please?

Click on left sphere to set it as camera target.  Now try control-dragging.  Target moves with camera.  Problem?  I think so.

Adam's work-around is nice, but perhaps not a proper long-term fix.  Thanks for help.

@Wingnut,

@MacSkelly

 i had the same issue once, i was told to use mesh.position.clone();

[Wingnut]

Not again!  hehe.  position.clone() has kicked my butt TWICE in 36 hours, now.  What a lamer I am.

Thx aW!

This will work if you don't need to follow a moving target.
