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"

[C++] How to get a reference to a class in the scene within another class

Right, so coming from Unity, you could literally make a public reference and drag it in, or a private reference and use getcomponent.

However, Unreal seems to be super confusing and there is no obvious way to do it that i have found.

I am trying to access my class "ALevelGenerator" in my Gamemode. Through this code:

.h public: class ALevelGenerator* LevelCreator;

.cpp in constructor LevelCreator = Cast(GetComponentByClass(ALevelGenerator::StaticClass()));

P.S i have the file #included too. This does not compile. Any ideas?

You have to specify in what class you want to cast it in,
try:

 LevelCreator = Cast<ALevelGenerator>( GetComponentByClass( ALevelGenerator::StaticClass() ));

Hope this helps,
Elias
