Hello. The title sounds weird, but I try to explain it better.
In Unreal Engine and Unity, source code files don't use main()
and other important functions. They have only a class. Like this:
```
class SomeClass: someInterface
{
AFunctionFromTheInterface1()
{
}
AFunctionFromTheInterface2()
{
}
}
```
And then all the source code files will be compiled into a single
.dll/.so library, so the game engine can use one in a game.
I don't know what compiler does Unreal Engine use, but it uses
C++.
Is it possible to do so in D?
