Can someone explain me what the point of a ResourceLocation is?

 

Like before we could create an entity like this

 

Entity entityX2 = (Entity) EntityList.createEntityByName("PrimedTnt", world);

 

But now we need a ResourceLocation.

 

Entity entityX2 = (Entity) EntityList.createEntityByIDFromName(new ResourceLocation("PrimedTnt"), world);

 

What is the main idea behind doing it that way?

A resource location is how Minecraft locates resources in the /assets directory.

 

They are also used as the primary key in the registry to uniquely identify various objects (Blocks and Items have registry names which are used as the default Resource Location in order to load the corresponding models).

 

Why entities use it like that, I don't know.
