Thank you for 4.2 from C++ perspective!

Dear Epic,

Thank you for 4.2 !

It was a lot of work to convert my c++ project over to comply with removal of the Classes folder

But now my compile times have sped about about 3000%, yes 30x faster!

Woohoo!

Thanks Epic!

Glad you’re seeing better performance, . Compile time improvements will be an ongoing effort. Unfortunately, there is no single place in the code that we can just fix - it’s more like death by a thousand paper cuts, but we have identified the biggest offenders. You should continue to see compile time improvements over the course of the next few releases.

Hi Gerke!**

Well thanks again!

I’m really really really noticing the improvement!

I can iterate in my pure C++ project soooo much faster now!

:slight_smile:

So by removal of classes public and private dir format compiling gets faster?

5

absolutely much faster! :slight_smile:

You will have to include all required headers for each class in the .h or the .cpp, but it is worth it in the end!

6

What about directories removal? Have not heard anything about it.
I never used that structure anyway, what has changed?

7

Yep, I’m interested to know what the difference is since it sure wasn’t just the directory structure - it must have served a purpose behind the scenes. I believe someone mentioned it used the directories in a precompiled header or some such.

Is there any info on this new convention and how this is practically different for C++ devs?

8

I didn’t notice any change in compile time (it’s pretty slow for me).

What changes did you do, ?

9

Did you completely remove your Classes folder? that seems to be the main thing to trigger much much much better compile times. :slight_smile:

It even works if you do this for plugins! So much faster!

No, but… where do you put your header files, then?

Currently I have the folders Classes, Private, Public and **Resources **inside Source/ShooterGame.

  1. You move all of the header files to private or public,

2/ if you use private, you add the private include paths to your build CS!


  //Private Paths
        PrivateIncludePaths.AddRange(new string] { 
			"VictoryGame/Private",
			"VictoryGame/Private/AnimationNodes",
			"VictoryGame/Private/AnimInstances",
			"VictoryGame/Private/Base",
			"VictoryGame/Private/Characters"
          }):

  1. Then you include each header in each .cpp

  2. some .cpp may need multiple .h included

end result =

vastly sped up compile times

it took me about 5 days to do my Victory Game project, but it is soooo worth it!

I can iterate so much faster now!
