Learning SDL2 in 48 Hours - GMTK Game Jam 2020
Вставка
- Опубліковано 18 чер 2024
- I used the 2020 GMTK Game Jam as an opportunity to try to learn how to use C++ with SDL2, a low level audio, input, and graphics library that you've probably heard of. In 2 days I was able to put together a simple game, and I learned a lot along the way!

I've always been intimidated by the SDL library but your source code puts it into a much easier context!
Thanks for that and the video

I tried your game... was pretty cool. The mechanics and art was awesome. :D
Thanks for trying it out! Glad you liked it :)

Love the concept, love the art style, would love to see a revisit to this game eventually.
Also the people that complained it was too fast may have a mouse sensitivity super high.
Wait, you can change the mouse's sensitivity?
@@CoolModderJaydonXYou didn't know that???
@@Konataware No. I figured that was baked into the mouse.
8:20 this was actually a problem I had with my first jam. A tip to anyone starting out: have other people play it because you're probably too good at your own game.

I felt that. ):
And also it doesn't btw.

Also Python is good

python is cool don't worry :)
@@PolyMars Frick yeah
I'm impressed that you choose a new library each game jam! I can see the benefit of it; you're time boxing your analysis of the library while making something complete without procrastination.
I like the concept of the game. Given your own personal goal of learning a library, does that mean you forego the design step I see from so many others?
Really enjoyed your Dev log, thanks for sharing! 👍
Thanks! Recently the extent of my design step in game jams has been coming up with a basic mechanic, and I make up the rest as I go haha
"BORING! SHUT UP, NERD" -Some guy from Dani's videos
Love the idea of a ghost, maybe the left click could be a sound the ghost makes to cause the player to 'jump' in surprise
bruh if there was a story to this is be like
"its been three days and already ive had to jump 400 of theses weird platforms that seems to never end, my legs ach in tiredness as i see the death courser getting close. another brace for jump but will i have the strength to make it this time?
"This is dani's typing background"

@dookie he also makes games but ok
“We have to put semicolons there because this is a real programming language, not python”
Correct me if I’m wrong, but you can use semicolons in python. It’s not required, but you can.
Lol, I was thinking the same thing
Doesn’t PEP8 complain about them?
Imagine thinking semicolons are the mark of a real programming language though; I guess that makes css a real programming language :D
Time to make a game using jquery!
@@dwhiffing Not a mark, but a requirement. CSS is a programming language in the same way that Bubblegum (esolangs.org/wiki/Bubblegum) is a programming language.

Flappuccino:
sfxr looks like a lot of fun! Been in need of some customizable retroish sfx, thanks for showing it off :3
Add a feature where if you hit something, then the character follows the mouse for a certain amount of time. So if you make the mouse a ghost, you can collect something that makes the ghost blue (like pac man) and if the character touches the blue ghost you die.
Omg I love how his drawings are so simple, yet so cute ^_^
3:03 I 100% agree with this man

Love SDL2! I open sourced a game engine that used it, and thanks to help from the community, it has been ported to 9 platforms, so cool!
codergopher's video series taught me a lot. I wish he continued making it.
Looks really good! Awesome work especially considering you made your own engine.
I love that someone shows that a gamejam submission don't works good all the time! Great video!

Cool! Inspired me to make a pretty cool game of my own. Love it!
Really nice work!
This game looks very fun! I wish there was also a reason to move anywhere but forwards (to the right). The first suggestions which come to mind: 1) click (or hold LMB / RMB) above player to duck, 2) long pit, a "bridge platform" for which is located higher than you can jump. Then there'd be some block, walled from the left side, but open from the right side. Jump on it and then on the bridge.
These are awesome ideas, thanks for the suggestions! I’ll try to implement ducking and vertical climbing sections whenever I update the project since they’d definitely add a lot to the game :)
@@PolyMars Awesome, looking forward to seeing that. ;)
Khud0 - Indie Game Dev kinda sounds like a mash of the google Dino game and robot unicorn from adult swim. An interesting concept
@@OpticSpycrab_OG I've never seen the robot unicorn before! Thanks, I've checked it out. Yeah, the ideas are certainly similar, but this time the character runs away from your cursor. :)
Khud0 - Indie Game Dev it is indeed a neat idea add in some combat or more difficult platforming then I see a fun game that I could play in my offtime
3:21 "I like you're funny words magic man"
No likes or reply? I’ll fix that
im confused on how you have only 21K subs, Your videos are too good for that!
“But, what next?” *ad plays* “TACO NIGHT”
Godspeed
First 3 min and we learn python sucks.
Jk lol
Cool video!
I would have two ideas, if you like:
Let the player character make an axious face, when the cursor comes closer :-D
Make him run into the opposite direction IN GENERAL (so it would never stop and the player is always forced to make an input or watch out)
i whatched this whole video thinking this was steven
but now i found another youtuber to whatch :D
nice work ... keep going !!!!
Sooner or later your games will be more portable than DOOM! You could pretty much port this game to anything
playing doom on the calculator be like
I think you could even play this on ps vita with touch controls
Considering Terrifried's impressive 5 consoles, i think it could go much further.
If you want you can still use semicolons in python...
Not that someone would ever want to.
YES
I use sublime text for my website and I absolutly love it, it's so good
I like the concept, I think that it is simple enough so that it could be used for a mobile game
My personal experience with SDL2 in my own projects has been largely positive. I was thinking of ditching it at one point because it seemed like it would ultimately be too high level at the end of the day for my usage, but then I learned a lot of games I know and actually like, such as Don't Starve, actually uses SDL2 and manage to make a very well-performant game so I've redecided on that. :D
also dead cells
0:57 Bfdi music makes me nostalgic
Not just bfdi.
cool game! I liked it a ton!
A small update I could recommend is adding a random limited spawn of enemies, some that jump, some that fly, some that walk, and some that just stay in place, I believe that would add some difficulty but to counter this you could simply give your little guy a laser that blasts these enemies away, but only shoot straight forward meaning you'll have to jump to hit the flyers. It wouldn't be hard to implement considering you know how to and it would give use to that ghost idea, giving the gloomy background purpose. 10/10 would try it out
is it just me or... you’re heavily underrated

“Banned him from knowing the definition of coding” what does that even mean?
@@voidpickle5684 it means yandere dev is a bad coder and its why the game runs like shit. Poorly optimized
Monogame is a c# framework that sounds similar to what you described as you wanting; high level enough to provide drawing functions n stuff, low level enough that you have to write your own physics, sprite handling, etc.
also my hot take is that I hate the way python and c++ both look. No brackets or semicolons? Disgusting. "::" and "
how about cocos2d-x if you want c++
"Well it's like a smily face, and you see it like bounces off of the walls" My favorite sentence of the video XD

@@dranonjagaming8365 Yeah- certainly not beginner friendly imo if you have any intention to expand out to other languages. The syntax is far too different, at best you might get to Lua from it.

You should include explosions when the cursor is clicked! Show the player what the guy is running away from! (Or make something scary appear on screen)
3:13 python would be very upset if python could read that
I love SDL a lot. I use it all the time
thanks, this is dope
I have an idea: In most jams, you can use anything people can download. So..... Make a game.... In scratch (or some other block based coding platform) Think about it: It’s not advanced, so you’ll need to think outside the box. You can download scratch files and also upload
Edit: No-one is going to read this, why did I comment it?
Cool idea... scratch is my go-to coding platform...
Scratch more like bore ragnorok
@Saltwater toaster Just because the scratch games you have played (or made) are boring, does not mean that scratch is, itself, boring. You shoulden't make generalizations like that based on a small and biased sample size.
thestarchypotat my guy
You can make some very advanced stuff with scratch, it was my intro to programming.
"Because this is a real programming language, unlike Python"

I don’t understand anything from these videos but they seem cool and I like them
To make it easier, you could make a circle that works as the radius of the cursor to move the guy. You could also make a person with low opacity at the same place as him that shows how high he’d jump if you clicked right now. You could add another mode where you can’t see it for people who want the challenge though.
