Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Unresolved External Symbol

Hi, I was trying to get another class to reference functions in this one. I got it to reference successfully but then after further work I got the usual 'Headers have been modified, close editor and recompile'.

It was on this compile in Visual Studio that I got this:

 Error    1    error LNK2001: unresolved external symbol "public: virtual void __cdecl AbeatsProto2Character::GetLifetimeReplicatedProps(class TArray<class FLifetimeProperty,class FDefaultAllocator> &)const " (?GetLifetimeReplicatedProps@AbeatsProto2Character@@UEBAXAEAV?$TArray@VFLifetimeProperty@@VFDefaultAllocator@@@@@Z)    E:\Users\mike\Documents\Unreal-Projects\beatsProto2 4.3\Intermediate\ProjectFiles\beatsProto2Character.cpp.obj    beatsProto2

I commented out all of my changes since the last successful compile. I tried right clicking the .uproject and choosing "Generate Visual Studio project files". This answer https://answers.unrealengine.com/questions/4191/unresolved-external-symbol.html implies that I need the line

 AbeatsProto2Character::AbeatsProto2Character(const class FPostConstructInitializeProperties& PCIP)

in my .cpp, but it's been there all along. Now I can't open the project from the UE Manager because 'The game module "beatsProto2" could not be found" since it's not compiled, so I can't do any more work =(
