-If you want to make a character and animate it get blender it’s free and learn the 10000 tuts that you have for it.
-If you are trying to script bla bla learn Blueprints , very easy to learn it with the amount of tuts it has.
Stop saying what you need and start learning, if you don’t understand by learning yourself hire a tut like Tesla or someone . THE END
If you want multiplayer than use as a host : open level1?listen and as a client open IP address it’s that easy to connect multiplayer to replicate things is the hard part
