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"

Save way to request JSON serverside

Hello, My goal is to create a simple "login" system, the player connects to server and enters a password and a username, the server sends the data via HTTP Request (GET) to a url (example: http://mywebsite.com/game/checkusername?user=john&password=bla≈ikey=3948324). Now I have the following question: I want to execute this "check" server-side in the gamemode bp, but I am unsure about the "apikey" (The Request needs an Apikey to verify that it is authorised to do this request)... I want to save it as variable (not replicated) inside the Gamemode. Do players have access to the default value of a string variable in the Gamemode at some point? I'm using a dedicated server and the clients never have access to the dedicated server files, but arent these variables with their default value shipped with the released game?
