UC Project is a foreign big capital of a UNREALENGIN4 project, why to analyze the project, because it is small enough and enough complete, unlike the official open-source UT, it is too large, and unlike other demos which only a technical point, These demos do not solve the Ue4 game engineering problems and process problems, such as the game's various menus (Main Menu/Pause menu/production staff, etc.), the switch between the levels, and even many peop

How should I connect to the server if unreal 4 only serves as a client? The official website does not provide blueprint network functions, which are available in C ++. 1. implement it by yourself and provide interfaces for blueprint use. 2. Third-party plug-ins. Plug-in: https://github.com/feixuwu/UEWebsocket 1. You have installed vs2015 or vs2017 and the c ++ component. 2. create a C ++ project, or create a new C ++ class in the blueprint Project (it will automatically convert the blueprin

First use UE4 to create a simple example of what you like to project, official, and then start your packing trip. The way to iOS As we all know, we have itunes installed. After the installation is successful, there are optional devices. When clicking on the Apple device, or the following error occurred. Anyone who believes in compiling the iOS version knows that if you want to package the project, you need a developer account.

Find the UEBuildWindows.cs file that records the version of the VS compilation that this version of UE4 can use Like what 4.19.1 version public enum Windowscompiler {// Version 4.9 Public enum Windowscompiler { ///visual Studio (Visual C + + 11.0).

Add a Class wizard in the class editor to generate the files and underlying macros required by the class Header file because UE4 has extended the C + +, it implements features such as serialization reflection, similar to QT practice: Add some macro keywords to the code and generate the corresponding C + + code during compilation. Therefore, for each class, there is a file that generates a Classname.generated.h class declaration Uclass ([specifier, s

NavMesh, this one demo can not see what the pros and cons, editing up to is very convenient Role control, like UE3, or Character+controller way, Character (Pawn) responsible for performance, controller responsible behavior. For AI, it is derived aicontroller to implement custom AI behavior Unlike UE3, blueprint can replace many of the original scripts. In addition, UE3 is more dependent on the built-in state machine in the script for AI behavior control, UE
