How to connect to ActorComponent Character through #include?
Once connected, there is a lot of mistakes!
Hello. I have my character named “ThirdPersonCharacter” and ActorComponent named “HealthStats”. I’m trying to connect “HealthStats” in my character through #include “HealthStats.cpp”, but I get a lot of errors:

You’ll need to provide more information to get any answer on this. The #include exposes the UActorComponent object to your ACharacter, if that’s what you’re asking. Other than that, I have no clue what your question is even about.
What errors are you getting? What are you trying to do?
Those aren’t problems with the #include, they just don’t show up until you’ve added the include because not having context for the compiler overrides other errors.
It looks like you’ve created some function definitions in the UHealthStats header file (.h) but haven’t defined them in the source file (.cpp); so the compiler is looking for those functions but can’t find them and throws the errors.
The UHealthStats::UHealthStats function is your constructor, and I think you need to include it even if it’s empty.
BeginPlay and TickComponent can be omitted if you don’t have overriding functionality for them.
Including the contents of your .h and .cpp files will help me provide more detail if needed.
