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"

NPC Patrol/Pathfinding

Hi, thanks for any help.

I'm attempting to get a patrol/pathfining system working in my game (city builder). The way it needs to work is after the NPC spawns it moves along a road (actors) until is has reached a set distance from it's start location and then return to the start location.

So far I have it working so that it either goes to the last road actor in the world or it will go to all of them in the array, doesn't work based on distance (haven't had a chance to get the return part working yet). Most of which is modified from watching the MOBA Minion/Creep series.

Screenshots are: AI Controller/ Get Nearest Waypoint (inside AI controller)/ Service on the route of the behaviour tree that should update to the next waypoint. alt text alt text alt text
