Hey, I am trying to create a new project using my existing cpp files.
I have succeed to create and copy and source file to the project, but in the “C++ Classes” folder I cannot see my cpp files although they are in Source file.
I have tried to GenerateProjectFiles, didnt work.
BTW I am using linux.
How can I import the cpp file into UE?

Dont copy and paste stufff straight into to your project folders, use import from visual studio instead.

As i have said, i am using linux. I do not have visual studio

After edit it did say that, it dosent matter you can still import from whatever ide you are using.

I do not think that you understood.
I am not talking at all about the ide. I meant that i can not see the files in UE.
You can on UE click “C++ Classes” then you will see on UE all of the c++ files. I cannot see them there although it is.
This is matter because I can not create a new class which inherits from my old classes. again cause UE cannot see them.

Well have you compiled the source? Generating project files will only re-scan your folder for new files not build them.

Tried to run “make” & it succeed. From the engine the compile fails but i can not see any errors on the log. it is just saying:

Running Mono…
/home/ssd/UnrealEngine/Engine~

In UE5 it may happen that the editor loses the C++ actor classes, in that case simply recompile the code will reimport the classes again.

Hi,

I tried exactly that, and it still didn’t work for me. Every time I close the UE editor and reopen it later, it loses the C++ Actor class on the project.

How to prevent this from happening?
I’m currently only doing a learning class project, but eh goal is to get my project going, and I’ll have a few classes, so I’m concerned about this.

Thanks

You need to close everything, and on VS, use “Development Editor” Solution, to do a build/rebuild. After that, once you open the Unreal project again, it will show up everything.

Additionally (optional), delete the folders
Saved/
Binaries/

Before doing Development Editor

This is the solution for the issue.
