My twinstick shooter project won't compile anymore

HI,

I built the entire twin stick shooter tutorial abou 1.5 years ago. I went to play with it again and I can not get it to even load because the source build keeps failing. I tried download he source files that came with the project but that has not helped. Here is the errors I’m getting in visual studio:

1>------ Build started: Project: UE4, Configuration: BuiltWithUnrealBuildTool Win32 ------
2>------ Build started: Project: TwinStickShooter, Configuration: Development_Editor x64 ------
2> Creating makefile for TwinStickShooterEditor (working set of source files changed)
2>EXEC : error : All source files in module “TwinStickShooter” must include the same precompiled header first. Currently “G:\data\Game development\Unreal\TwinStick\TwinStickShooter 4.11\Source\TwinStickShooter\TwinStickShooter.h” is included by most of the source files. The following source files are not including “G:\data\Game development\Unreal\TwinStick\TwinStickShooter 4.11\Source\TwinStickShooter\TwinStickShooter.h” as their first include:

========== Build: 1 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

my TwinStickShooter.cpp file looks like this:

// Fill out your copyright notice in the Description page of Project Settings.

#include “TwinStickShooter.h”

IMPLEMENT_PRIMARY_GAME_MODULE( FDefaultGameModuleImpl, TwinStickShooter, “TwinStickShooter” );

my TwinStickShooter.h looks like this

#pragma once

#include “Engine.h”
#include “TwinStickShooter.h”

do I need to clean out old files maybe?

Thanks,

Arthur
