Hi hi
I was created a blank c++ project (TestProject) and created other c++ template project of thirdperson (TempProject)
In TestProject, I create a character c++ (MyCharacter)
In MyCharacter class, I was following the TempProject, the TemplateCharacter class
however the error occur
the problem of the error is the line of code
UHeadMountedDisplayFunctionLibrary::ResetOrientationAndPosition();
may i know why and how to solve it ?
thanks 
Looks like your code doesn’t know what the function is. You may need to include the header for the code to be found. The documentation for the function can be found here: https://docs.unrealengine.com/latest/INT/API/Runtime/Engine/Kismet/UHeadMountedDisplayFunctionLibra-/ResetOrientation-/index.html.
At the bottom, it shows what module and header will be needed - “#include Runtime/Engine/Classes/Kismet/HeadMountedDisplayFunctionLibrary.h”
Thanks
is a mean need to add the whole path ??
cause
the default is:
#include “HeadMountedDisplayFunctionLibrary.h”
however error, I have been try
#include “Kismet/HeadMountedDisplayFunctionLibrary.h”
but is failed as well…
thanks:D, i try
Hi Ka Wai,
Try adding a string “HeadMountedDisplay” to the PublicDependencyModuleNames variable in your [ProjectName].Build.cs file (probably FYP_Game_Development.Build.cs file).
Somewhat like this:
PublicDependencyModuleNames.AddRange(new string[] { "Core", "CoreUObject", "Engine", "InputCore", "HeadMountedDisplay" });
Hope this helps.
This was the problem for me. Thanks!
I had this situation today, also in Unreal 4.25. It happens when starting with a blank UE4 project and then adding a First Person or Third Person UE4 Template Pack. On adding the template changes to project files are needed, because a blank UE4 project is missing HeadMountedDisplay.
Solution, adding
, "HeadMountedDisplay"
here in file: [YourProjectName].Build.c
PublicDependencyModuleNames.AddRange(new string[] { "Core", "CoreUObject", "Engine", "InputCore", "HeadMountedDisplay" });
