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"

Set Value As Object and Get Blackboard only working on begin play

In my game I have copied the content from a (FREE TO USE!!!) car ai project which I needed for my game. This included the level blueprint in which two nodes which were get blackboard and set value as object were present. While I am still unsure what these do they only seem to work when I spawn my enemy car ai and run that node on event begin play, but the problem is I need to run it at a certain event and not at the beginning of play, because I end up with multiple instances of the enemy car to run the blackboard nodes on, which I cannot reference before they have been spawned.

I try to refernce them at the same time I spawn them but it just doesnt work, so I tried it with it referncing every tick, (shown in the picture) but that doesnt work either. I need a fix urgently so if someone could please help it would be appreciated.alt text
