Content Only to C++ Project Guide
Here is a guide for how to transiation a Content only / BP project to a C++ project!
You retain everything you have in Blueprints, and you gain all the C++ power!
Alternative To Guide Below
I recently tried just using "File -> Add Code To Project" and adding each core class, game mode, character, HUD, and Player controller.
It works great! It's actually simpler than my method below, but you now have both to experiment with :)
You can also right-click on the .uproject file and generate Visual Studio files from there.
This guide is a non-destructive process for your original project!
You are only copying files from your current BP-only project, and so there is no chance of damaging your original project!
Just make sure to copy , not move, your original content folder :)
In other words, you can freely try this guide without concern of whether it succeeds or not, and I think you will find it is really not that hard!
Don't forget step 8 it is very very important!
Step 1: Download Visual Studio 2013 Express for Desktop
After installation is finished, restart your computer.
Step 2: Create a new C++ based project
Create a C++ project from the templates that Epic provides, using the one most similar to your previous game.
So a third person C++ project if you are making a third person game.
Step 3: Compile in VS
After the project is finished being created, Visual Studio will open and then you should right click on your new project name in the far right side of the screen and select Build.
Or from the top menu, find Build, and select Build Project
Everything should compile file!
Step 4: Open YourProjectGameMode.cpp
Comment out the line that starts with DefaultPawnClass, by adding two "/" in front
Step 5: Recompile
Compile this change in VS by navigating to
This .sln file is how you make changes to your project's C++ code!
Select Build->Build Solution
By the way, if you ever can't find the Build option, its because you have the text editor version of Visual Studio open, you have to re-open your .sln file to see the build option.
Step 6: Copy!
Delete the content folder for your new project!
Copy your Content and Plugins folder from previous project!
You may also want to copy some info from your Config folder of previous project, but dont just copy it directly!
Key bindings: if you dont want to set up your key binds again, copy the relevant portions from the Config files.
Step 6: Open UE4 Editor
a. Make sure all your plugins are enabled from your previous project by going to Windows->Plugins.
b. Go to Windows->World Settings, and Game Mode, and make a new game mode for your game.
c. Select your existing BP classes for your pawn class, HUD, player controller, etc, if you had them in your previous project.
At this point you have connected all the circuitry so that your C++ project is using the BP classes you made in your previous project!
Step 7: Reparent
a. Go to your base BP class for your Character, it should have Character.h in the top right, indicating who its parent class is.
Go to File->Reparent and select the name of the new C++ base class, YourNewProjectCharacter
b. Go to your new game mode class that you made and go to File->Reparent and select the name of your C++ base class, YourNewProjectGameMode
Now you have connected your previous BP classes to your new C++ code foundation!
