How to program a game in C++: #1 - Window and Pointers

[@Hallowfont]

Just a heads up to anyone who has an error with window_class.lpszClassName = "Game Window Class" throwing an error (error C2440: '=': cannot convert from 'const char [18]' to 'LPCWSTR'). In the properties of the project, go to general > advanced > character set > "Use Multi-Byte Character Set". This is how I fixed this error on Visual Studio 2019.

If you are having trouble creating the window in 2022, the LPCTSTR type for lpszClassName and for lpWindowName now need to be written as L"Game window Class" and L"My First Game!" with the L before the " "

[@jtcuth95]

I'm pretty familiar with C++, and I'm going through this series just to brush up on engine development a bit. But I want to say, that locker analogy you gave for pointers is the single best one I've EVER heard, and I can't believe I haven't heard it elsewhere. Props!

[@liamlluls1588]

Great video, two issues i had was, i need to put L in front of strings so L"my first game" and i didnt have a close button top right of window so i had to put in WS_SYSMENU on the create window line for window style "WS_OVERLAPPED | WS_VISIBLE | WS_SYSMENU"

[@atreyumclewin8282]

Recently decided to try making my own little games from scratch and found your series. I don't understand half of what's happening in this video, but I am so excited to learn! In only a half hour, I've already made my own window pop up, something I didn't think i'd be able to do until after college! Just graduated high school a little less than a year ago and have been dealing with doubts about my own coding abilities. But seeing what I can do here in such little time gives me hope, so thank you for that! Your videos are inspiring and you have created something good into the world, feel proud!

[@MassHypnosis805]

Exactly what I needed, thank you!

[@rachelveer7574]

This is SO exciting. Even though I knew bits of this a refresher is nice, I like knowing all the nitty gritty details instead of - let's say - Unreal/Unity holding my hand.

[@StellarMirage]

Oh, that's great, I did it with you. Last time I did it on my own I failed and almost gave up and then got this. Great way of approaching the problem. Thanks dude!!! I could create that silly blank window to hype my confidence up again :)

[@M3t4lik]

I couldn't close the window so I changed the case inside the switch(uMsg) to the following: case WM_CLOSE | WM_DESTROY: { running = false; }break; and it it now works as intended! I'm using MSVS 2022.

[@vanessabyerly3752]

So I followed along... and I got frustrated because a lot of the stuff was not working like it did for you. This was the second time watching the video, so I am glad I came back. I did make sure the windows.h library was on my computer this time, a simple google search for this helped out! I had issues with the lpszClassName giving errors. So I google searched that and came up with that I had to put TEXT in front of Game Window Class, so it looked like window_class.lpszClassname = TEXT("Game Window Class"). It may be because I have VS 2022, it could be a lot of things. But I hope that might help someone else down the road. Do not get frustrated with the code guys. If it doesn't work the first time, google is your friend. You can find just about anything out there when it comes to the error codes you get with the compilers. I hope this helps!

[@gamedudepc5684]

Your reply saved me from a half hour headache. I'm a beginner, this is my first lesson, and even googling didn't get me far as I understood nothing of the answers. You legend!

[@carolinambos541]

Thank you i was so confused by the error and this comment helped me out a lot!

[@alexjulius69]

Thanks a million dude, C++ is my arch nemesis, it pounds me into a confusion pulp, but with your tutorial I finally created a freaking window! Also, seems you can't define a string variable with quotes anymore, you have to use: string_variable = L"test" I don't know why, but you have to put that L in front of your quotes to not get an error xd

[@mkhadka123]

LPCWSTR expects a multi-byte char and a string variable is just a normal single-byte char, appending just an L (I too have no idea why the heck they made it like that) converts normal string variable to multi-byte char...alternatively you could set character set to "Use Multi-Byte Character Set" in Config Properties of the main project -> that saves a lot of manual conversion effort actually :)

[@gilernt]

[@noaxin]

Hey Dan! I followed your tutorial step by step but no window appears when I run the program like you did @ 8:54. Task Manager shows a process for the window but the window doesn't show up (not even on the taskbar). Also, when defining window_class.lpszClassName it's giving me an error saying "a value of type const char* cannot be assigned to an entity of type LPCWSTR". Could you help me?

[@DanZaidan]

Apparently, your compiler is expecting a Unicode string (LPCWSTR). You can define one by putting an L before the string like: windows_class.lpszClassName = L"My Class Name"; Alternatively, you can make the Window Class be of type WNDCLASSA to make use it will use Ansi (the default) strings. Like this: WNDCLASSA window_class = {0}; window_class.style = CS_HREDRAW|CS_VREDRAW; window_class.lpfnWndProc = win32_window_callback; window_class.lpszClassName = "Window Class"; Let me know if it helps you! :)

[@Glitch900]

Why at 3:59 there is a video edit that doesn't allow the viewer to see how you got to that documentation page, I downloaded the whole pdf and searched for WINDCLASS, and it doesn't show up. This is always a kill joy on these tutorials when the person giving instructions just randomly jumps to another page without showing how they got there.

[@Glitch900]

I realize this video was made 3 years ago so a heads up to anyone just barely jumping in like me, there is no WNDCLASS information, you can pull up WNDCLASSA, documentation under winsuer.h, I found the latest information is from 2022 so be aware you might need to dig like I did to follow along with this video. Hope this helps.

[@Glitch900]

Also, like user @andrewcampbell4960 pointed out do the following to clear the error with the .lpszClassName "In properties of the project, go to advanced > character set > "Use Multi-Byte Character Set". and that will fix your problem.

At this point, the window should be created and destroyed very quickly (just flash on the screen). I used the debugger to set through each line of code (by pressing F10) to see the window before the program exists (and the window closes). A little bit layer in this video I add the input loop so that the window stays open. Try to plow forward a bit, and if the problem persists, paste some code and I'll try to help you further. ;)

It's still in the switch, but why the distinction? Which case(s) apply to running=false; and which case(s) apply to break?

Hey! Thanks for the guide. Quick question: at 4:51 we can see that when you hover over lpfnWndProc you are getting a little tooltip that links to some documentation. How are you getting that? Hovering or selecting that text just shows me a tag.

[@DanZaidan]

I'm glad you are liking it! Actually I have CS_VREDRAW under the cursor at this point (lpfnWndProc is only selected via Shift+Arrow Keys), so it shows the tooltip for the macro (pink text). If you don't see, I'm not really sure, I have installed VS2019 specifically for this series. You can watch me installing it on episode #0 (with the Windows SDK, so maybe it has something to do with it?) and I haven't added anything to it. :P Visual Studio is kind of a mystery... hahaha Sorry I couldn't be more useful.

Hi! This means that "CreateWindow" is expecting "wide characters" for the window name (characters that support the whole Unicode format). You can easily fix this by calling CreateWindowA instead (also make sure that RegisterClass has the A sufix).

Hi! I think the problem is that you are creating an extended window (CreateWindowExW) and not a "normal" window (CreateWindowA). The former requires more arguments: (See: docs.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser-createwindowexw) Try calling the "normal" window creation function directly (CreateWindowA instead of CreateWindow or CreateWindowExW) and see if it helps. :)

It Saya hwnd and the other stuff in the callback function thing are unidentified, how to fix

[@Paul1miller1]

I dont know if this is beginner friendly. I'm trying to follow and I dont understand any of these concepts yet. I think I have to go do some reading on C++.

First off, thanks for the video :) Everything works fine, until 12:00 in the video, towards the end. "warning: no return statement in function returning non-void [-Wreturn-type]" The problem for me started when you changed... return DefWindowProc(hwnd, uMsg, wParam, lParam); to... return result; Here's my code: LRESULT CALLBACK window_callback(HWND hwnd, UINT uMsg, WPARAM wParam, LPARAM lParam){ LRESULT result = 0; switch(uMsg){ case WM_CLOSE: case WM_DESTROY: { running = false; } break; default: { result = DefWindowProc(hwnd, uMsg, wParam, lParam); } } return result; } I got it working by putting "return 0" within the WinMain{} block, as the last statement, figuring that if an error occurs, then the return value will not be 0. I'm using Mingw64, with Notepad++ Maybe it's a compiler issue that won't allow me to run the program while WinMain expects a return value, even though the "return" value has already been provided within the LRESULT CALLBACK window_callback() function. Perhaps?

I get the error below at '=' in the line window_class.lpszClassName = "Game Window Class"; a value of type "const char *" cannot be assigned to an entity of type "LPCWSTR"C/C++(513) I also get another error shown below in the line CreateWindowA(window_class.lpszClassName, "My First Game!", WS_OVERLAPPEDWINDOW | WS_VISIBLE, CW_USEDEFAULT, CW_USEDEFAULT, 1280, 720, 0, 0, hInstance, 0); argument of type "LPCWSTR" is incompatible with parameter of type "LPCSTR"C/C++(167) I followed along exactly and should get the blank window but for some reason the types don't agree and I am not sure why and don't know enough to fix it. I have tried several things like using a wide string by putting 'L' in front of "Game Window Class", but that doesn't fix the other error. I've tried CreateWindow without the 'A' and tried other versions of CreateWindow but always end up with errors.

for the first problem i guess u can go to properties in the project > advanced > character set > "Use Multi-Byte Character Set". it's fixed my error

[@WorldGamer-vq7wv]

my mans keyboard is on fire

[@mjmares]

I had a problem with the wide strings but then i put L infront, bc the wind api likes wide strings? idk can someone example why that works?

[@hadiaabq7981]

[@Gnarkson]

Its a wonderful tutorial! Great man, continue with that, please!

[@prankbyte6125]

There is an error in the statement "window_class.lpszClassName = "Game Window Class";". It underlines "=" saying that it cannot be a const char value for LPCWSTR. How do I fix this?

[@zenitsu950]

im so mad no one replied to this with a fix lmao

[@Digitalman271]

Coming here from C#, which I came to after doing this via python. This is soooo much harder..

[@capitanDeLoFortuito]

I really want to do this tutorial, but my Visual Studio seems to be different than yours, I don´t have the Properties option, for example

[@stephanieezat-panah7750]

whew! made it! you are amazing, but, wow

[@zeeninjapanda8505]

on create window it is underlined in red and i cant get rid of it... How do i do that?

[@DanZaidan]

Try posting your code here and I'll try to help out. :)

[@hadiyahalkauthar]

*MAKE SURE TO COPY IT EXACTLY!!!* I had the same problem and it was because I only had one "CW_USEDEFAULT" when there should be two. Here's what you should copy: CreateWindow(window_class.lpszClassName, "Your name", WS_OVERLAPPEDWINDOW | WS_VISIBLE, CW_USEDEFAULT, CW_USEDEFAULT, 1280, 720, 0, 0, hInstance, 0);
