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"

How can I grab a particular component off of a root component?

I am trying to grab the Static Mesh Component off of my root Component, which I am doing right now by using GetChildernComponents which returns all Children. Then I go through all of the components looking for there name to match up, EX: SM is the StaticMesh Component. I However would like to look for them by there type and not by a name. I tried IsA(), but I could never find the right parameters for it to Run. So my question is, if I have an array of all Child components how do I check the type of them so that I can use an if/switch statement to stop at the Component that is the StaticMesh, Or the Collider,ETC. Also is there a way to query the RootComponent for a particular Component by type.

hi, you didn't say what your root class is, but assuming it is ACharacter you could maybe use these methods ?

     virtual UActorComponent* FindComponentByClass(const UClass* Class) const OVERRIDE;
     template<class T>
     T* FindComponentByClass() const
         return AActor::FindComponentByClass<T>();

they are both defined in ACharacter.h and if they aren't what you need maybe you can take a look what those methods do and implement a variation of them. Hope that helps :)

This is what I need, however I seem to be unable to get it right, but would the Parameter for the function be, it says that OtherActor->FindComponentByClass(UStaticMeshComponent); is invalid, the error being Type name is not allowed.

You're getting that error because you're not passing in the right type of argument, this is what you should be doing: OtherActor->FindComponentByClass(UStaticMeshComponent::StaticClass())
