All Unreal Courses

Add this as your final line:

You have to use this command, unless you run it in debug SHIFT-F5, otherwise it runs and closes the window

It waits for a key to be pressed before closing the window

Everything was running smooth until I got to the functions lesson. I’ve been confused since. I guess I’ll have to go back and rewatch until it’s more clear. :slight_smile: Great course so far!

They’re currently remastering the course, and what you saw at the beginning was the new content where they’re using a later version of Unreal Engine 4 along with VS Code. Section 3 hasn’t been completed yet, and so is using the original videos from when they were using older versions/programs. In time these will be updated too; we just need to wait. :slight_smile:

Here is my work to share :slight_smile: tho I’m not sure if it’s the right place to do so :confused:

it is a basic function of the compiler with the latest Win10 update. its been a thing for about a year now. it simply means that your code is actually running fine and its put there for the purpose of decoding. your code is running fine.

Hi, the links above to the courses do not work for me. Also, when searching for them at udemy, they cannot be found.
Any hints?

I am having trouble when I put in cl in the terminal, it says command not found for the record, I used the console to open VS Code

Hi Ben! I just bought full Unreal courses content on Humble and was confusing.
Previously I bought course for Unity on Udemy and it was great. Very useful QA section, subtitles and other stuf. But Humble gave me codes for and there no even subtitles, which is sad cause English is not my first language. Is there any coupon for Udemy same courses If I already have on
Thank you!

My Triple X game so far. You guys make it so easy to understand!

I’ve been working on Bulls & Cow game. However, it seems as though my private variables declared in BullCowCartridge.h are not all getting initialized. The only one that seems to work is the bool bGameOver. The other variables are not getting color coded recognized types. For example, the TArray Isograms that I’m trying to set in the BeginPlay is not accessible in SetupGame. It sees it as an empty array and crashes Unreal when I attemp to run.

Hello, I just finished the triplex game and when I added the #include statement at the beginning of my game to help with the randomization of the code, my computer (Windows Defender) seems to think it’s a trojan named Watatac.B!ml and quarantines the triplex.exe file.

Here is my code… I’ve muted the ctime line to test my theory and the computer runs the program fine. Please explain why this is occurring and what I can do to correct it?


//#include //accessing computer’s time FOR some reason this code is causing Windows Defender to view it as a trojan

As MCMM said, it looks like it compiled. In case anyone else finds this useful:
if the intent was to see the string output into the terminal, after entering hello.cpp into the command line to compile, as was done in the screenshot, enter hello to run the compiled program. This should output the string into the terminal. Reviewing video 18: “Hello, World!” in section 2 of the Unreal Engine C++ Developer course should help.

TripleX Game. Had my sister it out and she couldn’t figure it out because of Math. LOL

[ SOLVED!!!] I’m having this really annoying problem from ages. can anyone help me fix this??

When I try to build the lights, import/export assets (including scripts), save a scene or anything I do in unreal engine, it crashes with this bug…


Fatal error: [File:D:/Build/++UE4/Sync/Engine/Source/Runtime/Windows/D3D11RHI/Private/D3D11Util.cpp] [Line: 198] Unreal Engine is exiting due to D3D device being lost. (Error: 0x887A0020 - 'INTERNAL_ERROR')



MASSIVE improvement to compilation times

I just want to share that I had been experiencing really bad compilation times of over 5 minutes while working on the bullcow game. I just saw video 52 (Solving Slow Compile Times) and after changing my UE4>Engine>Binaries>Win64>, my compilaton times went down to just a few seconds.



welp here is my code for the game so far. turns out you dont need to type cout for each line of code if u want to display multiple lines of text. that one one of the biggest things i learned making this version of Triple X my own. i think its easier and more clean to have it this way.

// not sure why this wont fully put the block of code into one place but hope this works

using namespace std;

int main()
//dialog for the overall game!
cout << " You are a rouge who has been given a mission for the king.\n"
<< " King Sung Jinwoo: I have summoned you, my greatest agent, for\n"
<< " this mission! The objective is to save my beloved daughter,\n"
<< " the princess, by sneaking into the tower of darkness where\n"
<< " she is being held captive by the dark wolf (Askoo)! Inside\n"
<< " the hidden chamber there is a sacrid spell put on the door that\n"
<< " requires you to solve a math problem that even I, King Sung Jinwoo,\n"
<< " have problems understanding." << endl;

//const is used to keep vairables form being re decared by mistake or even on purpose!
const int SpellA = 4;
const int SpellB = 3;
const int SpellC = 2;

const int SpellSum = SpellA + SpellB + SpellC;
const int SpellProduct = SpellA * SpellB * SpellC;

// Print sum and product to the terminal
cout << endl;
cout << " Your spell seeker gem shows u that there are three spell numbers blocking the door." << endl;
cout << " They all mutiply to get " << SpellProduct << endl;
cout << " As well as add up to get " << SpellSum << endl;

cout << " Activated Spell unlocker tool.\n"
	 << " Enter your 3 spell combinations: \n";
int GuessA, GuessB, GuessC;
cin >> GuessA >> GuessB >> GuessC;

int GuessSum = (GuessA + GuessB + GuessC);
int GuessProduct = (GuessA * GuessB * GuessC);

if (GuessSum == SpellSum && GuessProduct == SpellProduct)
	cout << "Spell code unlocked. you have saved the princess!\n";
else {
	cout << "You have entered the wrong combination! you have been captured!\n"
		 << "game over!";

Back at UNREAL … stay tuned for some good stuff…

Please give me a solution for this problem

Run the “Developer” prompt. It will set the environment variables so that cl.exe is a recognized command. I start the prompt up by hitting the Windows key. I type “2019” and pick “Developer Powershell for VS 2019” from the list.
