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"

How to pass information to a Blueprint Child from SpawnActor

I am making a random maze with the common random maze generator, but I am including doors to be locked with keys. The idea is to have a chance of spawning a key in a room, and then that key will open a door somewhere down the maze. I want to link a given randomly spawned key to a randomly spawned door by indexing them both to the index of the room that the door is attached to. I am spawning the door with the SpawnActor function as well as the Key, but I'm not sure how to pass the "current room" index to the actor being spawned. Is there a simple way to do this or any other methods of doing what I want? Thanks in advance! Just as a visual of what I have and what I want, here are some pictures. What I have: alt text
