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"

Listen Server MMO?

I get that a dedicated server is likely created so anyone in the world can generally join the game. Listen servers are more local. But are there any problems with using only listen servers for an MMO game?

Besides he fact that it has one extra player because they spawn with the creation of the server?

Problem is that the player is the Server and he can technily cheat very easily. Basicly you give Client Authority over the Game and every Problem that comes with it. Advantage is that you don´t have to run any Server Infrastructure since anyone can create a Server where others can Join (also globaly you only need a IP to connect)

I assume you talk about classic MMOs like WoW, Guild Wars and that sort that have a certain Persistance Layer, account Management, Ranking Systems, etc. thats something you dont want to give into Client Hands ever =)

There is also what you can call a Hybrid. You got Listen Servers that can do Request to global Servers but never directly access or Modify Data on that global Server. But its often Hard to verify the Data that comes from the listen Server since the global one does not know much about what actually happens ingame.

Do a bit of research its covered somewhat well across the Internet.
