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"

Why Can´t I Set BlackBoard Value as ACTOR?

Isn´t it possible to SET the BlackBoard Value as ACTOR? only as Object?

If so, why??? I can GET, but not SET?

Using Object instead of Actor should give you the same results. Object is a basic class, so technically an Actor is just a subclass of Object. For my AI setups, I typically use Object and I've never run into any issues.

Have a great day

Hi, thanks, but the problem is a node that only accept an actor reference, and my object reference isn´t acepted, can´t hook them because of this, but I will find another solution, thanks

Could you explain exactly what sort of setup you are trying to achieve? Also, could you provide a screenshot of what you currently have set up? Thank you.

Hi Sean! No problem, you were right, as an object is also an actor I have managed to find a solution, so thanks again!

Hi JonnyMachony,

A general suggestion I could offer would be to try to set the Blackboard value as an object, and then if you need to use it as an input for something that accepts an Actor reference you can cast your object reference using a Cast node into the actor that you'd like to pass in.

Something like this:

Let me know if that helps.
