The class of the main processing network in UE4 is Unetdriver, and the Unetdriver class has the following two members [CPP] view plain copy print? Class unetconnection* serverconnectio

First of all, the official documentation is wrong, and in version 4.10, the binding function does not work in the constructor of the role class. 2016.2.12Here, for example, the role classFirst, add the following in the header file:ufunction () void Onoverlapbegin (classclassboolconst fhitresult sweepresult);Onoverlapbegin a collision function defined for itselfThen add the binding function in the Setupplayerinputcomponent function in the CPP file:Startcollectionsphere->oncomponentbeginoverlap.ad

Method 1: Draw with draw.The blueprint for inheriting the HUD draws a custom pattern with draw material,draw texture and other screen-drawing methods that are suitable for drawing a simple mouse.(If you don't need an offset, ignore the float-50 in the blueprint)(Attached: node show Mouse cursor is true when the system mouse pointer is displayed during gameplay and allows the pointer to move outside of the game window.) ）There are not many strange problems with this method, but the disadvantage i

Functions marked with Blueprintimplementableevent do not require a method body in C + + code, and the method body is implemented in the blueprint.Usage:1, the function name is now defined in the C + + header fileufunction (blueprintimplementableevent) void Ondepleted (); 2, add the Event in the blueprint, find the corresponding function name, after creation can implement the concrete logic3, you can finally call the method in your own C + + code, which automatically calls the Blueprint fu

questions See: http://blog.csdn.net/zhuyingqingfen/article/details/53147947 There are two ways to solve this problem , which are OK, 1. The function of synchronizing random seeds between different computers is added. 2.

recognize the color and variable types in the UE4 Blueprint :Each color in the UE4 corresponds to a different variable, and the color of the connection point and line represents what type of variable is here. For beginners, the first to see so many connection points,May be very confused, how to even, if you know the color corresponding to the variable type and then to find the corresponding module to connec

Can see, some complex, especially for me this UE4 and Android are not familiar with the people, only want to not, first of all, my needs are not complex, but in a model and reality overlap space using the motion tracking function of Project Tango to walk, rotate, etc., simply, I am now in the office environment, using 3D modeling to do an office-like model, long and wide to the right, so with the tracking of Project Tango, I can only look at the scree

This problem is because the machine is missing a compiler, just configure the location of the compiler itself.The first step: you create a new Bin folder under any folder, and a AMD64 folderStep Two: Open the \vc\tools\msvc\14.11.25503\bin\hostx64\x64 directory of your own VS installation address, copy the contents into the Bin folder, and copy the files into the AMD64 file.Step three: Open the RegistryHKEY_LOCAL_MACHINE\SOFTWARE\WOW6432NODE\MICROSOFT\VISUALSTUDIO\SXS\VC7 change the key value of

The official wiki has a FPS C + + Tutorial, which is a good way to understand all aspects of UE4 development. It's just a record of what you've learned. Gamemode/config/character from this can be seen in the UE series on the game's underlying features or a good frame, compared to unity will obviously feel that the difference between the two is to provide you with a lot of commonly used features, whether you use not to. If you want to use it well, yo

Recently implemented a real-time mesh vertex animation in UE4, with a large number of vertices (hundreds of thousands of levels) The first is to create the dynamic Vertex Buffer, then each frame to update the vertex data, found that the efficiency is lower The bottleneck of efficiency is in the calculation of vertex coordinates, after all, there is a lot of Then changed to be based on vertex Texture (material in the World Position Offset) Implementati
