COMP4300 - Game Programming - Lecture 02 - Intro to C++ (1/2)

Memorial University - Computer Science 4300 - Fall 2023
Intro to Game Programming
Professor: David Churchill - www.cs.mun.ca/~...
This is a course for students interested in learning the fundamentals of game programming and game engine architecture. Topics include an introduction to: vector math for games, rendering, animation, and artificial intelligence, collision detection, game physics, and user-interfaces. Students will be writing fully functional games using an ECS (Entities, Components, Systems) architecture, using the C++ programming language and the SFML graphics library.
Course Assignments / Files will not be released publicly

I found gold! This course is great, I learned a lot! Thank you Prof. Churchill!

What a marvelous domain of the language. I´m not a (direct) student of yours, but how wonderful that would be. Just hoping those young students know how lucky they are, with many poor teachers..

[@bryanswaggbeast4594]

absolutely agree

[@EstebanLopez-bn9pd]

Your passion for C++ is contagious. I thank you for posting this course on KZbin!

Hello, about the vs endl - at 1:17:09 you mentioned that if you save the program's output to a file and then open the file on windows, it won't show newlines if you use , and it seems you're suggesting that with endl it will. It doesn't matter if you used or endl, it will have just LF endings with both, because you compiled and ran the program on a linux machine. Similarly if you compile on windows, will actually result in CRLF endings and so will endl. The only difference between and endl is that endl will flush the stream, while won't.

Great intro! we are using C++ on a Intro to Computer Graphics course at KTH and this is just gold! Thanks!

[@gitgudsec]

Thanks for deciding to list this course after all!

[@jeremythibeault]

Thank you for this class, I'm really enjoying it so far. I did manage to write the function in two lines but I will admit it's not really clean and your example changed my view of c++. I'm looking forward to watching the rest of the series, cheers! def loadFromFile(self, file): with open(file, "r") as data: self.students.extend([Student(*line.rstrip().split(" ")) for line in data.readlines()])

Thank you! So much sound advice 🤗

1:13:54 It doesn't seem like the lecture was over yet. It got cut off in the middle of a slide. 😢

[@DaveChurchill]

It cut off like 30 seconds of the end. The university lecture capture ends at a specific time and I went a bit late

[@arjanvandenheuvel4522]

@@DaveChurchill Ooh okay. Thanks for clarifying, I was afraid much more might had gotten lost.

[@Anubis10110]

When you said Define a limit .. I was like damn calculus is everywhere 😅

[@RaviSingh-lc1tc]

All in good spirits with open(file_path, "r") as f: for one_line in f.readlines(): first, last, id_, avg =one_line.rstrip().split(" ") Student(first, last, int(id_), float(avg))

[@blackcitadel37]

is that python?

Hello Professor Dave Churchill. I am not one of your students but a viewer here on yt and I have a question regarding the unsigned int/ size_t. How come I don't get the same error as you do in 1:28:10 ? I am on visual 2022 btw.

[@yiitAy]

can it be a c++ version thing ? Maybe . i write so many very bad c++ code but i didnt take any errors hahahaha

[@bunpasi]

Perhaps you use a different compiler than gcc? If you're up for it, have a look at compiler warning levels and have a quick look at the difference between debug mode and release mode.

[@Euphorya]

You need to add -Wall to your compile command to have these show up as errors. `g++ main.cpp -Wall -o runme`.

[@pingu2538]

At 1:49:24, m_name is set to "Course". and in the public constructor below it you pass the reference to the string m_name. My question is what will happen to the string "Course" after m_name's reference has been changed to something else, will it sit in the memory till the end of the program? If so, then is it possible to run a loop to create new strings and keep changing the reference to it. What happens then?

[@elvis8180]

are you planning to create a c++ course only? from fundamentals to advanced levels? btw, thanks for the course.

[@michaelcarey6415]

Hi, thankyou for sharing your lecture. At the end when you create the Student class object within the addStudent method(2:04:00), is it not necessary to assign the object a variable name as you did earlier (1:38:00) with the call to the Constructor? Thanks

[@DaveChurchill]

Since you are calling it from an instanced object, it assumes you are calling the function related to that object. It's like in python when you say self.function(), in C++ you either say this->function() or leave out the 'this' entirely

[@michaelcarey6415]

Ok. Thanks for the quick response

[@funnylife565]

I am a c++ programmer doing numerical computing for ten years. I find it very difficult to get a c++ job right now comparing to java.

[@felipe6040]

I though C++ was good for machine learning and stuff, games as well. So it's that good to learn it nowadays?

[@meenakshirai]

doesn't auto make C++ dynamic language? Same as swift using protocol for it's functions and makes swift dynamic language as compiler has to guess at runtime what type or which class the protocol is going to pick up, isn't C++ going to find out the same way against auto?

[@DaveChurchill]

@@meenakshirai no, the preprocessor just determines the type from the context, it is a compile time type inference

[@lordofthe6string]

I'm not a student, but it's a really helpful resource. I think the ideas so far are great and I think it's going to be a good course, but my god is c++ a garbage language. I can't wait for another low level language to take its place.

[@alexanderskusnov5119]

It's not for Windows.

The story about "a.out" looks really interesting .. en.wikipedia.org/wiki/A.out Greetings from Germany.
