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"

Can anyone help me with simple multi-player?

I know there's been a lot on here about the topic, but none of it that i found is really helpful. Basically i would probably like to start simply with being able to play my game with someone else in my house (On a different computer). I would then try to expand on that by having multiple servers and playing with random people like other games.

Any information would be appreciated, Thanks!

UE4 use more professional term called "Replication", as network multiplayer is about replication of one state in another state in different computer. So if you search by "replication" you might find documentation and tutorials ;] Here overall documentation about online multiplayer: https://docs.unrealengine.com/latest/INT/Gameplay/Networking/

UE4 Networking is working through a listen host. This listen host has all rights for replication, which means, that every time a client wants to display or share something, he needs to ask the sever for this.

This is handled by replicated variables and actors that are shared across the network and replicated function that are executed on servers but called from clients and other way round.

I made a basic Networking Stream a few weeks ago, maybe this helps you:


There is also a Framework Page for the Network that tells you which class works for what and which classes are available on clients and server and which not:


I hope that gets you started!
