Static Const, Make Const Versions of UE4 Types

From Epic Wiki

Overview

Dear Community,

Using Constant versions of complex variable types can be useful, 

especially if these variables are used every tick but their values never change.

To make a Constant version of something like an FLinearColor or an FName you can do this:

.h 

public:

static const FLinearColor Red;
static const FName HeadSocket;

.cpp 

// Copyright 1998-2013 Epic Games, Inc. All Rights Reserved.

#include "YourGameGame.h"

//////////////////////////////////////////////////////////////////////////
// AYourClass

//you declare the static const outside of any function, but make sure to include the YourClass:: part :)

const FName        AYourClass::HeadSocket = FName("Head");
const FLinearColor AYourClass::Red = FLinearColor(1,0,0,1);

AYourClass::AYourClass(const class FPostConstructInitializeProperties& PCIP)
	: Super(PCIP)
{

}

Keep Global Namespace Clean

Make sure to specify your class context when you declare your static const variables! 

Myclass::

Summary

Enjoy!
