The character The server then replicates it to client which means you do have to copys of “ConstructionManager” on the client then. This server communicates with the Login map that contains the UI elements for a user to login with the email / username and password. 在UE4的C++代码中，可以使用如下API创建TCP Server和Client： - 创建Server：通常使用FRunnable接口或者继承自FRunnable的自定义类，并重写其Run、Init、Stop、Exit等方法。 - 创建Client：使用FTcpSocketBuilder类 At that point, you could also move some game-play logic (economy, player profiles etc) to a standalone web application that Unreal (the game server not the client) talks to via VaRest or the built in UE4 REST api support. Looking forward to BnS UE4 update for the private servers . Unreal Engine 4 versions this tutorial supports 1.

If you used “Create Widget” on begin play you could use “SwitchHasAuthority” and run remote into the widget and bypass the create widget node with the server pin and continue execution on the other side of the add to view port it if you couldn’t find any other way to implement it. The only way I can think of atm would be to write a server-function and call it from the client with the direction-value, I don’t know what an UE4 package looks like, but I guess the less packages, the better the efficiency.

Then the server spawns the player 在UE4项目工程中添加“ 专用服务器(Dedicated Server)”的功能，可以参考下面的步骤。1 准备源代码版本的UE4引擎下载某个版本的UE4引擎源代码（这里我们使用的是UE4. You have the RPCs function marked with the UFUNCTION() macro (see in the declaration) in which you have:. Download Unreal Engine to unlock the full potential of real-time 3D creation. Same thing happens between “server and client”. How can I do that?
