Position a 3D object in relation to another with Babylon.js

[DellaFree]

Hi, I am a newbie, that recently I started studying Babylon.js . I would ask , though it may sound trite and silly , how to position an object in relation to another ? Let me explain: I created a cube and a pyramid , separated , and I view them in a canvas ; now I would like , through a function that will be called by a button , position the pyramid above the cube . I would understand, how to implement this function in order to position the pyramid above the cube , no matter where I place the cube ( the cube could move) . I repeat I'm a newbie and I have not even a starting point to show you an example . Any advice is welcome . Thank you again for your attention .

Hello and welcome..

 

I think you can do this:

pyramid.parent = cubepyramid.position = new BABYLON.Vector3(0, 1, 0);// AboveORpyramid.position = cube.position.add(new BABYLON.Vector3(0, 1, 0));// Above

Great it's what I'm looking for. Is there another way to get the cube's height, instead using the value 1 ? Thanks a lot.

You can use mesh.getBoundingInfo().boundingBox.

 

Here are the properties of the bounding box:
