问题 I am using Perforce as part of a small development team. Everyone was able to connect to the P4V client except for one person who gets the following error: TCP receive failed. read: socket: WSAECONNRESET We have deactivated his McAfee firewall and virus scan, but the error persists. I really don't know what to do with this error and it seems to be rather undocumented on the perforce website. From what I gather, it's because it's not a perforce-specific issue, but rather a TCP communication

问题 How can I play test my GearVR game on my development computer without building and running on my phone? I'm looking for either an answer for a game built with either Unreal Engine or a Unity3D. 回答1: Dont playtest without a headset "Playtesting" on a PC completely misses the point of playtesting in it's regular meaning. Playtesting VR apps is important, and has to be performed with a headset. One of the biggest challenges of designing VR games is ensuring a comfortable (not nauseating)

问题 I need to run a code generator before starting compilation\execution of my code in Visual Studio 2015. Is there any way to add a script that will run my .bat.py file when I click "Start Local Debugger"? I use UnrealEngine 4 and in my project there already are some .cs files that use precompilation scripts, but these scripts are not fired if the project is already up-to-date. Any solutions? 回答1: Open properties of your startup project in VS (should be your game, not UE4). You need

问题 I followed the steps from this tutorial: https://wiki.unrealengine.com/How_to_Link_External_C_Libraries_.dll_.lib_With_Your_Project_%26_Package_With_Game,_Fast_And_Easy I was able to successively reference the external c++ library and the project compiles just fine. However, at runtime, when I instantiate an object from external library, I get the following error: Exception thrown at 0x00007FFD7244FD31 (mscordacwks.dll) in UE4Editor.exe: 0xC0000005: Access violation reading location

问题 I'm trying to convert a struct and the data it contains into a legitimate JSON String. I work in Unreal Engine in C++. Struct I'm trying to convert: USTRUCT() struct DATALOGGING_API FGURaaSDataStruct { GENERATED_USTRUCT_BODY() public: UPROPERTY() FString id_session = "test"; UPROPERTY() TArray<FData> data; }; Struct that is used in the previous struct: USTRUCT() struct DATALOGGING_API FData { GENERATED_USTRUCT_BODY() public: UPROPERTY() FString data; UPROPERTY() FString tag1; UPROPERTY()

问题 The following is the JSON file I am trying to parse:- { "GameSetting":{ "Num_Levels":"3", "Env_Type":"Indoor" }, "Indoor":[ { "Name":"simple room", "objects":[ {"objectName":"chair"}, {"objectName":"tables"}, {"objectName":"boxes"}, {"objectName":"barrels"} ], "number_of_objects":"10" }, { "Name":"multistory", "objects":[ { "objectName":"chair"}, {"objectName":"tables"}, {"objectName":"railings"}, {"objectName":"staircase"} ], "number_of_objects":"25" }, { "Name":"passageway", "objects":[ {

问题 I want to use async/await syntax in C++ (UE4 framework), but due to cross-platform code I not sure that is possible... Or possible? If yes, how can I use it? And also there are await and __await ( resumable , yield and __yield_value also) keywords that highlighted in Visual Studio. What's difference? Maybe not all compilers supports this keywords or supports separately? gcc , clang are accepts it? Or not accepts and I can just use macros for each platform individually. 回答1: async and await

问题 I've created an interface for my UE4 project that has an import button. What I want it to do is to access FBX files in the user's desktop and opens the one the user selects. I've written a c++ code that searches for FBX files in the desktop and returns their names, if found. I'm kind of confused/stuck at this moment, and don't know exactly how to continue. My question is: Shall I open the FBX file using c++ or blueprints? It would be much appreciated if you could elaborate more on the

问题 I am developing a mobile app for my school with Unreal Engine. I am using C++ (looking for free viable compilers). For said app, I need to create user accounts, and my CS teacher wants me to use Google to authenticate accounts. Due to the very limited amount of data on said integration is available online, I was unable to find any resources. How do I add a "connect Google account" function to my app? Thank you. This is for an iOS mobile application that allows the FBLA presidents to manage
