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"

Pushing function in c++ to blueprints

I am new to c++ and wanted to learn how to make my AI better so I followed this tutorial: link text

I got to the bit about overriding the function in blueprints after the character and realised that I made a mistake in my code as I couldn't find the function I defined in c++ anywhere in the list of overridable functions. I can't find the mistake as I am so new to c++ and hope that someone can. I didn't do the AI controller part as I prefer altering those settings in blueprints and it said that it was optional to do that step I know that it is a lot of code to look through but I would really appreciate it if someone could help me find the problem even if that is to link me to another question with the same problem.

You don't need to declare implementation function, UFUNCTION macros do that for you. Also, check if your BP inherits from correct class.
