how to get the player view point location and rotation in ue4 c++

To get the player's view point location and rotation in Unreal Engine 4 using C++, you can follow these steps:

1. Get a reference to the player controller: The player controller is responsible for managing input and controlling the player's view. You can get a reference to the player controller by calling the GetPlayerController() function on the game mode or by using the UGameplayStatics::GetPlayerController() function.

2. Get the player's pawn: The pawn represents the player's in-game character. You can get a reference to the player's pawn by calling the GetPawn() function on the player controller.

3. Get the player's view point: Once you have a reference to the player's pawn, you can use the GetViewPoint() function to get the player's view point. This function returns the player's location and rotation.

Here is an example code snippet that demonstrates how to get the player's view point location and rotation in UE4 C++:

#include "GameFramework/PlayerController.h"
#include "Kismet/GameplayStatics.h"

void GetPlayerViewPointLocationAndRotation()
{
    APlayerController* PlayerController = UGameplayStatics::GetPlayerController(GetWorld(), 0);
    if (PlayerController)
    {
        APawn* PlayerPawn = PlayerController->GetPawn();
        if (PlayerPawn)
        {
            FVector ViewLocation;
            FRotator ViewRotation;
            PlayerController->GetPlayerViewPoint(ViewLocation, ViewRotation);

            // ViewLocation contains the player's location
            // ViewRotation contains the player's rotation
        }
    }
}

In this example, we first get a reference to the player controller using UGameplayStatics::GetPlayerController(). Then, we retrieve the player pawn using GetPawn(). Finally, we use GetPlayerViewPoint() to get the player's view point location and rotation, which are stored in the ViewLocation and ViewRotation variables, respectively.

Remember to include the necessary headers (#include "GameFramework/PlayerController.h" and #include "Kismet/GameplayStatics.h") at the beginning of your code file to access the required functions and classes.

I hope this helps! Let me know if you have any further questions.
