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 can I get continuously spawned AI to follow the previous spawned one?

Firstly, I'll just say that what I'm trying to do is set up a version of snake but with 3D models following behind my first person player character. I have been having problems getting the spawned AI to attach at the end of the line. I have gotten them to spawn every time I hit a sphere, but then they just stand there. I'm pretty sure that I can set it up with an array, but I'm having a hard time updating the array every time a new one spawns.

Bonus, if anyone has a good idea how I can get them to spawn directly behind the previous incarnation, instead of a dedicated spot.

Forgive my ignorance, for I am but a newbie.

Thank you in advance

I should also mention that I can get placed AI to follow me just fine.

I also know and have fixed the break between the array and set value as object bits of the NPC_AI_BP screenshot.
