I am trying to use methods from unreal source code, in my c++ project which will create a blueprint node, I can include them without error but when I build my project/compile I get linker 2019 error. Any idea how to resolve this? the source code is in the path of the project.

Assuming you are talking about engine code, it’s likely that you will have to add the module that those classes fall under to your dependencies in your Build.cs file.

Thanks, engine is already in the build file, also I added the mainframe (where the function is) the problem still persists.

Hmmm - I’m not too sure then sorry 
Wait - Just to be sure… You’re including the header file right, not the source file?

yes, the header file I include, and no issue while including but issues arises when linker tries to link
