Yes both are object oriented programming

I meant that an engine such as Truevision3d implement a traditional OOP style while Unity and Torque x propose a new approach to OOP

3DGS is in my opinion a precursor of the component phylosophi

I remember when I switched to 3dgs some years ago, from TrueVison and blitz3d mainly because they lack an editor, that I found 3dgs programming style a little odd

Which is better?
Well probably it depends on taste , not to mention that you can have hybrid solution in the same engine

John Kanalakis is of course on Component side but I tried to use Torque X , believe me it is not that easy
Traditional OOP may have some drawbacks but also the new approach has its issues
Go through Torque x tutorial projects , they are far away from being intuitive

Unity3d is a little easier because it supplies a lot of prefabbricated components while Torque x supplies only the basic ones but even Unity is not that easy to use

However getting back to my first post

I wonder why people consider Unity3d an engine for artists
Unity3d is not an user friendly engine, maybe it is a powerfull engine but I would not say that it is an engine for "non programmers "
Maybe they tested the editor only
