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 a door open in both ways depending of player's location ?

Hi everyone !

I have a little problem with my game. I've made a simple door system that works fine but I need it to work on both ways, so the player always open in front. I've already find the way to detect where is the player with the door but I can't figure out one thing :

-For a door, there is "3" states, right ? One at the middle, one open at the top, and one open at the back (see image) alt text

If the player are in front of the door and he press E , he can just pass by "Flipflop" node by 1 to 2. If he want to close that door it return to 1.

BUT, if the player are beside the door (from the other side) and the door are already "2", he need first to close it "1", and then open it "3". And I don't know how to do that.alt text

I've use a "dot vector math" solution to detect where is the player, but can't figure out how to make thses states and be able to close and open the door wherever I am. Thank you in advance !
