How can I change the FPS camera sensitivity to look around in C++? Or is this not something to do in C++?
You can scale the value from your controller input when adding it in your pawn/character. You can do this in Blueprint or C++.
In C++ it may look something like this:
(but the same functions are available in Blueprint)
//.h
UPROPERTY(EditAnywhere, BlueprintReadWrite)
float MouseSensitivity = 0.5f;
// .cpp
void APawn::PitchView(float Val)
{
AddControllerPitchInput(Val * MouseSensitivity);
}
void APawn::TurnView(float Val)
{
AddControllerYawInput(Val * MouseSensitivity);
}
