Summary
In this chapter, you were introduced to one of the most important and useful features of the Unreal Engine multiplayer environment, remote procedure calls, or RPCs. As you have seen, they allow you to execute functions from a server to a client and vice versa.
In this chapter, you called requests from the client to the server, by improving the character sprint system and by adding interaction logic between the character and other Actors in the game (i.e., the dungeon doors). Rest assured that, by the end of the book, you will also have seen other use cases for RPCs as they are quite ubiquitous in multiplayer games.
This chapter ends the second part of this book – starting from the next chapter, you’ll be working on implementing some AI logic over the network. Let’s spice things up by rounding up those pesky Lichlord minions and giving our character a challenge to step up to!
