Need help. Way Too many errors to continue coding at this point


error4|689x123

After creating and including header file HiddenWordList my whole programm isn’t working anymore. I have put my 3 files of code down below. Sometimes it shows 4000 errors and sometimes only 2 and sometimes 5. I have tried the option “rebuild project solution”, but it didn’t work and I can’t open it in unreal

My HiddenWordList.h:

#pragma once
#include "CoreMinimal.h"

const TArray<FString> Words = // here I get error saying "variable FString is not a type name"
{
	TEXT("milks"),
	TEXT("cakes"),
	TEXT("kings"),
	TEXT("plums")
};

My BullCowCartridge.h:

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

#pragma once

#include "CoreMinimal.h"

My BullCowCartridge.cpp:

What version of Unreal and Visual Studio are you using? Have you tried File > Refresh Visual Studio Project in Unreal?

I am using Visual Studio 19 Community Edition with Unreal Engine 4.26. I don’t know how to refresh VS19 project in unreal since I can’t enter unreal. I get following messages:
error5
error6

That would mean you have a compilation error and no built binaries to fall back on (I assume because you just deleted them)

Go into Saved > Logs and then post the most recent log.

I presume you didn’t end your Words variable with a semicolon

TArray<FString> Words = 
{
    // words
    // ...
}; // <- missing semicolon

actually I have:

What about your class definition?

class UBullCowCartridge : ...
{
}; // <

er8

I only use words here

That isn’t your class definition. The class definition is in the header file.

I didn’t put Words there

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

Right, but that’s not the reason you’re getting a compilation error. The error says you’re missing a semicolon before line 5 of BullCowCartridge.cpp

Would you mind showing the start of that file?

this is my start of the file(line 5 is the start of the definition void UBullCowCartridge::BeginPlay()):

// Fill out your copyright notice in the Description page of Project Settings.
#include "BullCowCartridge.h"
#include "HiddenWordList.h"

void UBullCowCartridge::BeginPlay() // When the game starts
{
    Super::BeginPlay();
    InitGame();
}

void UBullCowCartridge::OnInput(const FString& Input) // When the player hits enter
{
    if (bGameOver)
    {
        ClearScreen();
        InitGame();
        PrintLine(TEXT("Nr. of possible words: %i"), Words.Num());
    }
    else
    {
        ProcessGuess(Input);
    }
}

Is that log the most recent? i.e. the one without “backup” in its name?

yes

Then that’s a bit confusing since I’m not seeing any missing semicolons.

However the fact that you’re getting an underline for FString in this screenshot

Makes me think you saved the HiddenWordList.h somewhere else. Could you hover over the tab so it shows the path?

image

It should be under “Source” and if you didn’t change the path when creating the file it’s most likely under “Intermediate”. It needs to be in the same location as BullCowCartridge.cpp (in Source).

it saved it for some reason in D:\Programming\C++\GameDevCourse\BuildCowGame-starter-kit\BullCowGame-starter-kit\Intermediate\ProjectFiles

Yeah, VS Community will default to that path for Unreal projects, most likely due to the generated files that are created. There should be a note about this in the course.

he mentioned that vs will default save it somewhere else then its supposed to, but I wasn’t prompted to set the location to which I want it to be saved, so I just hoped for the best. Is there any way I can fix this

Just move the file in File Explorer.
