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"

I'm afraid you will have to recompile the engine from source of you want to add a component to the engine APointLight class.

However that is not the way I would approach this. There's a cleaner way to do what you want and doesn't involve recompiling the engine from source.

Just create your own APointLight class inheriting from APointLight. Then create a uproperty pointer in the header to hold your post process component.

 class AMyPointLight : public APointLight
 {
     AMyPointLight();
 
     UPROPERTY (Edit anywhere, BlueprintReadOnly)
     UBoxComponent* PostProcessBox;
 
     UPROPERTY (Edit anywhere, BlueprintReadOnly)
     UPostProcessComponent* PostProcess;
 }

Then in your constructor create the components

 AMyPointLight:: AMyPointLight ()
 {
     PostProcessBox = CreateDefaultSubobject<UBoxComponent>("PostProcessBox");
     PostProcessBox->SetupAttachment(RootComponent);
 
     PostProcess = CreateDefaultSubobject<UPostProcessComponent>("PostProcess");
     PostProcess->SetupAttachment(PostProcessBox);
 }

Then in your scene use your own pointlight instead of the engine one.
