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 do i implement 8 direction swipe function

alt text

hey guys, I am trying to implement swipe functions into my game, so essentially determining whether the person swipes N, NE, E, SE, S, SW, W, NW and then outputting into a function based on the direction they swipe.

I have figured out how to do N, E, S, W (up, down, left, right) however, I am stuck on the diagonal functions. (NE,SE,SW,NW)

Hope that makes sense, Thanks guys alt text

ok so i tried the acos approach and it didnt seem to be working out so i done some research and tried the atan2 function instead with the broken up X & Y values and now works perfectly. thank you so much for your help :)
