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 make an actor (NPC) follow a spline?

I'm making an aquatic ambient where there are some fish which follow a path (spline) but I just dont know where start, I can't find a good tutorial to do that. so that's why I'm asking your help. If you know somthing that can help me, I'll be very grateful. I find a plug in iTween but is buged and is not possible to compile so is impossible to build the game.

Although iTween makes it very easy, I think is better do it without plugin.
