Mate??

great explanation

My big objection to Ubuntu these days: Snap. I am ok with it being an option, I am ok with Canonical offering it, I am not ok with removing packages and then installing the Snap, I am definitely not ok with the developers writing some function to automatically use the Snap install command when the user types "apt install <program>" and that for fundamental programs like the Firefox browser. Not cool in my book (not respecting users their decisions, one reason why I ran away from Windows) but mostly my objection is that it costs too much effort for me as tthe user to fix my system. Usually the Snap is much slower (it seems that Flatpak does a bit better and I would love to see a comparison between these both and nix), it requires more memory (not a huge deal but it does matter) and of course there are problems with breaking theming though I am willing to believe that that now mostly has been solved. Other than Ubuntu I don't really care that much but I do need a system with more recent updates because I like to play games. I have been on Arch in the last 5 or so years, I like it but it isn't perfect (issues with some packages not being done the way I would prefer it). I would also be fine with Fedora or SUSE. The distro is just a starting point and you can make any distro work, it is just about which distro gives you the least amount of work for your usecase. Maybe a tool like Distrobox can help in cases where you do have a problem, not sure. For example the install-process of MATLAB being a hell for Arch-users (due to the developer making some weird choices).

Guys, can we agree that getting ready to play with SDL on Linux and macOS is a lot easier compared to doing that for Windows. 😆Just saying, Microsoft can learn a lot from the open source world (macOS is based on FreeBSD, hence the same workflow) about userfriendliness for software-management. Just typing one command to install a text editor (vim) or an IDE and SDL2 and 10 seconds later you can already start your project. On Windows you first have to find the right websites for both Visual Studio and SDL, you get a very slow install process for Visual Studio (I never understood why that takes so long) and when you finally get ready to start your project you have to puzzle how to get it done in the GUI while you are a beginning programmer and barely know what all of that means.

On Arch anyone who has a general gaming-setup has SDL2 too (used by many games) and the name of the package is sdl2 so people can figure that out. :)

I think we could reduce calculations by prioritising the normals, that are similar in direction to the vector that goes from object A to B

Your passion for teaching is inspiring

Just an awesome explanation

FWIW, shifting is common in microcontroller code as often we need a particular bit at a different location in the byte.

Beautiful explanation thanks… any chance to do a video on using logic to do arithmetic?

Hallelujah😄

Have you seen John Lin's voxel engine yet? It is mind-blowing!

I dont understand why exactly we have to test a->b and b->a. In wich case theres a collision between a and b and not between b and a?

Thank you Gustavo !!! you are an incredible teacher, you have thought me so much... I am AAA game engineer, but I am still learning and will be. Started the Atari course and took the GameEngine one, and the rest will follow ;) If you don't mind a suggestion for your next course( very excited for the PS one ) GameBoy programming would be incredible. Cheers!

I don't understand how just dividing by w you can normalize everything. If I have this vertex { -2.0, 0.0, 0.5 } and my projection parameters are fov = 60, aspect = 1.0, Znear = 0.1 and ZFar = 1000, I get w = 0.5. Projected X will be -3.46 and obviously, if you divide -3.46 by 0.5 it's the same as doubling it.

I get it now. The bigger the field of view, the bigger the objects 😂

being able to find y' at the end made me so happy 😄 you are an awesome teacher!

your classes are amazing!! ty very very very much

Wolfenstein 3d and Comanche came out in the same year, but you would never guess by just looking at them.

this is amazing, you are a great teacher!! ty

Great video although already seen it on your personal website. Would love it if you did a video on what skills are needed as a Game Developer maybe a high level overview even if it is just pointing to other videos you already done so there is some sort of pathway for people. I've seen a few students who have done a 'Game Design Degree' and they only seem to get taught the bare essentials of C# and then the focus is on Unity / Modelling / Animation and Rigging. Anyway here is my wishlist for what video you should do next (either paid or free) Data Structures and Algorithms and applying it in a Game. Pointers.. maybe a brief video on that I've purchased most of your courses and they are great but I'd love it if you made your next one focusing on portable hardware. I'd personally love it if you did something with one of those Tamagotchi devices.. heck even a Furby lol or a Pocketstation or Dreamcast VMU but I'd get it if you wanted to do something with more broader appeal like a Gameboy. (in ASM ofc not gamemaker stuff a lot of people are using for Gameboy games thesedays.)

Thank you so much for this video! I needed to make rope physics for a project and at first i didnt understand anything from wikipedia but this video made it really simple.

great stuff

So I think I ununderstand, it looks to me this specific transforming by translation using matrices, with the added dimension represented by one, being a way to regulate so that unit vectors remain accurate, which is reliant upon origin. At least that's what my brain allowed this very early morning 😂

Great work! Thank you for detailed explanation of such an important thing for all people who doing some staff in computer graphics!

COOLEST thing heard this Year ♥

Creating a Game Loop in an extremely old version of C & SDL.

Wonderfull explanation of verlet integration. Clear, simple and explicit. Thanks a lot for this.

Im gonna try doing this with compute shaders

when you added SDL2.lib and SDL2main.lib to the dependencies, how did you know to add them? if I were to do this myself from scratch where would I be able to see or discover "oh, I need to add SDL2main.lib in addition to just SDL2.lib"?

Why is it not considered redundant effort by WIndows MSVC projects to have to manually add the lib to BOTH the library directories AND the linker? what is the reason for it not being able to deduce the linkage based on the included libs?

At first, I didn't know where you were going with the shearing, but you blew my mind there at the end. Bravo!

if the objects in my scene are subject to acceleration will the method still work?

feel when now its github download link, and theres no lib folder

nice video but the audio issues are crazy

love the way you go through things. true understanding and logical connection of related topics. fantastic content

now it all make sense thanks to you

Ok, for whatever reason, instead of tracking the vector, you're looping through all the pixels in the bounding box (And repeat ten times what a bounding box is. Everything so insanely long winded.) and wasting time with the cross product. Then when you get to optimization with a fixed step, you still keep going through all the X's. It's so painful to watch.

Oh my god, thank you so much for your explanation. I'm making a video game about a sewing mechanic and I needed to simulate the rope. This help a lot

Aleluia! :)

It reminds me the time of demomakers in the 90s

install on linux: quite easy. install on mac: hmmm! easy too install on windows: incantations n magic spells, windows need true love kiss to work

Muito bom !

This video is missing a huge component: how to calculate the collision normal n. For spheres, I think this is the difference vector between the two centers of the spheres at time of collision.

oh dear lord.. 3 hours whew. i'll be back! SUPER happy that this is online.. i've been wanting to find a place that would teach me the voxel graphics/engine/ whatever. bless you sir. but i'm gonna need to start this on a fresh day.

Bro let's contact please
