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"

Behavior Tree : Dynamic Subtree Injection question

I've been trying the dynamic injection of subtree. How does the inject tag thing works. I'm aware that there are no tutorial or much doc on gameplay tag, but how do you populate this list?

If you open your DefaultEngine.ini, add the following:


Now in your Edit->Project Setting, you will now see a Gameplay Tags setting. Simply add the tag you want and they will show up in the UI.

I did as you said (and fixed the path for the data table I created), and restarted the editor, but the gameplay tags still don't show up. Do you need to do anything else?

restart UE4,the DataTable's index must start 0.

Thanks it really got to work.

However , I've been digging through the half-done documents on gameplay tags. It seems that there's a lot of test can be done on tags but absolutely no way to 'add' them. How do you 'ADD' a tag to an actor.

I'm specifically needing it for an EQS test of Actor has GameplayTag. seems to be no way to add tag at all.

I also want to konw.actor tag is not GameplayTag,I think UE4 not finish for GameplayTag,maybe need C++ extend.I think GameplayTag is for static asset,classes or layers data.The actor tag is more dynamic,like a name.Sorry,my English is poor,I can't express more.
