What is a nested compilation?

Question

I get links to this post today on all social networks. It seems that some people have made a useful piece of code for working with "nested teams." This thing has something to do with the development of 3D games and, in particular, with Unity3D, which, apparently, does not support ^(?) Them out of the box.

But what is a nested compilation?

Answer 1

A prefab is basically a prototype of GameObject (potentially a hierarchy of GameObjects ), with attached Components and their relatives sets of serialized properties .

When you put a Prefab instance in the scene hierarchy, we can say that you have a prefix instance in the scene (or a GameObject related to the assembly ). This is very useful because if you modify the compilation file itself, all modifications apply to related collections in all scenes.

Now, for your specific question: Unity does not support nested prefabs natively. Prefabs are atomic objects in such a way that you cannot specify hierarchical relationships between them.

For example, if you have 2 prefab A and B and you create a third prefab C file that has A and B as children, Unity will consider C as a completely separate collection, so if you change A or B , modifications will not be actually distributed on prefab C
