Unreal Engine

Currently using UE4 (4.7.6)

Variable names

If you want to use real variable names but have nice names in the UE editor too, then use meta/DisplayName

UPROPERTY(VisibleAnywhere, BlueprintReadOnly, Category = Camera, Meta = (DisplayName = "First Person Camera Component") )
    UCameraComponent* m_pFirstPersonCameraComponent;

Logging

In game output of your logging, like chat text:

if (GEngine)
{
     GEngine->AddOnScreenDebugMessage(-1, 5, FColor::Blue, TEXT("AFPSCharacter is being used") );
}

Source control

The minimum you have to put under source control:

/Config
/Content
/Source
Project.uproject
