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"

Custom component visualizer in plugin


I'm trying to add custom component visualizer in my plugin and I'm getting an "unresolved external symbol" error. This is the code that I've added in the StartupModule in my Module.cpp.

     TSharedPtr<FComponentVisualizer> Visualizer = MakeShareable(new FGraphVisualizer());
     if (Visualizer.IsValid())
         GUnrealEd->RegisterComponentVisualizer(UGraphVisualizerComponent::StaticClass()->GetFName(), Visualizer);

This is the error.

1>Module.cpp.obj : error LNK2019: unresolved external symbol "public: __cdecl FGraphVisualizer::FGraphVisualizer(void)" (??0FGraphVisualizer@@QEAA@XZ) referenced in function "public: virtual void __cdecl Module::StartupModule(void)" (?StartupModule@Module@@UEAAXXZ)

Am I missing an include somewhere?

Also, has anyone managed to create a custom component visualizer and include it in a plugin?

Ok. So after learning a bit more c++ turns out that the error was exactly what it said. I declared the constructor but didn't implement it.
