how to move a mesh with FreeCamera?

[Hagop]

Hi

This question might sound simple but...

I import a shopping cart into my scene using SceneLoader.ImportMesh. I want to link the cart to my FreeCamera so that when the camera moves, the mesh will follow the camera.

 

If I declare

cart.parent = camera;

the cart vanishes

 

So instead I am using

cart.parent = camera.parent;

which doesn't make sense to me but at least the cart does appear in the scene but does not move. Any ideas ?

Hagop, with :

cart.parent = camera;

you are effectively standing in the cart

 

Try adding an offset to the cart  with:

cart.position = new BABYLON.Vector3(x,y,z);

and adjusting the x,y,z values until the cart appears where you want it. My guess - just the y and z values for the cart to be in front of you.

 

You may have to scale the cart too.

 

Then parent to the camera.

 

Hope that helps.

 

cheers, gryff

Thanks gryff for the reply. I can import, position and adjust the cart. However, what I want is the cart to move with the Free Camera. In essence I want  the cart to be a First Person View. Additionally I want the cart to move left and right when I move the Free Camera with left and right arrows, but when I move the camera up or down with up and down arrows, I want the cart to remain still.?

This is such a nice hack, iiceman :-) You can save like 2 nanoseconds every second doing that - http://www.babylonjs-playground.com/#1LT3VZ#1

I see, because it's a direct reference of the rotation... no need to set it over and over again, cool!
