babylon Why is there a name required for many Object creation ?

[GrosSacASacs]

In BabylonJs there are many constructors that require a name like

 

var box1 = BABYLON.Mesh.CreateBox("Box1", 10.0, scene);

 

Where "Box1" is the name. Why is this useful ? How can we use "Box1" later ?

Hi GSAS!  Yes, take a look here...

Now use your browser's "search this page" feature... for 'byName'.  You'll see that there are many "byName" methods.  If your project doesn't need any getMeshByName calling, then mesh names are not important for any other reason.  You can have many mesh with the same name... in a scene.  Under nearly ALL circumstances, it doesn't matter.

When using a loop to produce an array of meshes, many people add the loop's indexer to each mesh name... like this:

Perhaps others will have different opinions, though.  I may have forgotten some issues, but I don't think so.

You can also add tags to scene items, and use our powerful get-by-tags system.  It is MUCH more versatile than getByName or getById methods.

My short answer: names are necessary if you import a scene - e.g. because it was made in Blender, or because you've loaded a scene that was previously serialized.

If you're just creating a scene and managing your own references then you don't need to worry about them.

Consider them as a tag, or an identification. Use them only if you wanna.
