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"

Checking if player is looking in a specific direction?

I am trying to make a horror game, and am trying to make a jumpscare class. It relies on the player facing a certain direction and triggering an event. I came up with a solution that checks the player rotation and if they're in the trigger box (Not yet implemented). I was wondering if there was an easier way or a more efficient solution as I have noticed in a lot of horror games, that a "scary" event only happens when the player faces a certain direction, or looking at a specific object.

You would probably be best to use player forward vector and the world position of whatever you want them to look at and get the "DOT" product of the 2 vectors will give you an angle in degrees or radians, and then you can compare this to whatever the player's field of vision would be to tell if the player can "see" the trigger event.
