Technical Devlog: Implementing Audio into my Game Engine

[@ThinMatrix]

This is a much more technical devlog than usual so if that's not your thing then this one might not be for you (and if it is your thing then yay, enjoy!) We'll be back to more visual features next time with the UI makeover.

[@Ferenc-Racz]

I love this kind of content, which is a bit more technical. Congratulation for the huge amount of progress. :)

[@deadpl55]

I'm learning game development and i like both or them but this type of content i like most

[@user-ob5hj5vn8c]

I agree, this is the content I like the most actually! :)

[@artymer5021]

I actually quite enjoy the more technical content. I find it not only interesting but also very inspiring. I am an aspiring game dev as well so these videos often fuel the muse haha

[@melekRebai]

Both are great but as a non game developer i really enjoy watching technical dev logs cuz it allows me to see a different aspect of programming

[@jprice_]

Everyone crying over unity while this mad lad just chills with his own engine. Absolute legend.

[@Duke6598]

lmao, actually so smart from thinmatrix to do this looking at it retrospectively. Best unintended business decision

[@faluhub]

You're saying this as if it's not actually a problem that unity's doing this.

[@pedroduran8927]

1. Unity fixed pricing with a 2.5% revenue cap, becoming cheaper than unreal. 2. Making an OWN engine consumes time, you have to be VERY GOOD at math / vector programming to just have some level of a simple camera rendering a cube. 3. Even making an engine that returns an executable application is a real PAIN. now imagine trying to produce multi-platform game on an own engine 💀 Engines costs money because they save time and resouces. You can always go godot but it has its sharp edges too.

[@jprice_]

@@pedroduran8927 Why even touch godot when king released their own engine for all to use? Both Unity and Godot have a smiliar issue - they are led by a buffoon.

[@willcollins5121]

@@pedroduran8927ehhh this is built on lwjgl cross-platform isn’t a huge issue here

[@finalforeach]

The procedural sound system you made solved a problem I wasn't even aware of! I suspect most game devs will run into that issue at some point. Glad to be following this series.

[@Zonix_Official]

I'd assume as a by product of this, when it comes to implementing Sound to your Minecraft Recreation that this will majorly help! Nice to see you also watching ThinMatrix, FinalForEach! :D

[@finalforeach]

@@Zonix_Official I stand on the shoulders of giants! ThinMatrix's videos is how I learned to make good looking water graphics after all.

[@haydenap]

Man the procedural sound effect thing you did for variable interaction time is so cool. Great solution to that problem.

[@lukasjost44]

I think this is exactly how it works in Minecraft

[@jamesbaconreid]

Love the sounds! Especially the procedural ones - that's so cool!

[@raphaelvinh]

Can we talk about how good this transition at 1:26 is ? good work man !

[@alejorag]

He does it a lot but everytime I see it I still marvel at it lol it just looks so clean

[@Joshimuz]

I appreciate the more technical videos! The procedural sound generation for the arbitrary length actions was super nice!

[@szabados1980]

Actually I prefer this sort of devlog videos to where only the game play features are shown. 👍👍👍

[@JustATempest]

For building compound sounds, I would recommend using a builder pattern, as you're effectively building a track. You would create a compound sound with an add track method that takes a track, and returns 'this', allowing you to chain addTrack function calls, that way you don't have a block of variables defined in a row like at 12:35 with incrementing variable names like track0, 1 2 3. You've used the builder pattern with sound 2D builder I think it would work really well with compound sounds. If only to keep consistency of the code. It's still be a good idea. You're using the factory pattern, for the digging sound effect which is a good idea. When you combined with patterns, a new world opens up. Imagine a sound effect factory, that can create the sound effect you need, and using the builder pattern to configure the given sound effect as a compound sound.

[@justred2337]

I love it how you carefully explain everything while also making a game using Java, most people just use Unity and C# to make basic stuff but you made your own engine! Would love to playtest someday, keep up the awesome work!

[@GetaVe]

Elegant solution and it sounds like it works well. My main suggestion is less harsh sounds like metal and hard rock. And more soft crunchy sounds.

[@lucavogels]

Wow! The sound generator idea for the tools was really smart! 😱

[@AustinCameron]

Watching this while writing my own AudioController for an audio book app.

[@SharkyGamess]

It’s amazing what sound effects and music can do! Brings the game to life 😍 keep it up!

[@msajidsarker]

You have a brilliant mind, and you are creating the most beautiful little garden simulator to cultivate peace.

[@sirynka]

It'd be cool to change the pitch of the sound during the digging or water pouring process so the player would have an intuition on how long the action would take without even looking in the screen.

[@ThinMatrix]

Nice idea!

[@madmanmax120]

@@ThinMatrix To add onto this, it'd be an awesome bit of polish to have, for instance when harvesting a section of crops, to have the "harvest" sound rise in pitch over subsequent harvests. So basically crop 1/5 will be the lowest pitch, 3/5 being in the middle, then 5/5 being the highest, scaling in pitch depending on the size of that particular group of crops. It builds a sense of rising accomplishment when you have an audio source do that, very similar in to how Minecraft does their sfx for breaking blocks. Or y'know, just implement it on a smaller scale and just do it for each individual plant. I think it'd fit right in with your farming game here!

[@AgentM124]

And not everything has to follow this system, you could also increase the frequency at which sounds are played to give a sense of speedup. That way not every action sounds like a fire alarm.

[@LifeOfMohammed]

I love how far you have come with this and like I love how good the videos are getting with all the transitions and all looks so good! Have you got a goal in mind for releasing this game? I also love the out-of-monitor transition so much haha also pretty neat you are using ur own tutorials to remember stuff!

[@ThinMatrix]

Thanks! I'm currently aiming for end of next year, but that might be a bit optimistic.

[@LifeOfMohammed]

@@ThinMatrix That is awesome to hear sadly I was abit to eager to try it out so its awesome you uploaded it on Patreon!

[@Alex-fn7kj]

End of next year ?!! But your game and his loop already is so polished, adding new content like plant and tool and farm upgrade okay, but if you leave yourself until end of next year it mean we haven't seen half of the systems and mechanics build implemented yet, right ? 👀

[@ramoncf7]

Your OpenAL tutorials helped me to add sounds to my game, just for the effort and work it took you to create all those tutorials (and the OpenGL ones) I'm wishing you the best, you're an inspiration for all indie gamedevs! Thank you.

[@clonkex]

I love the secateurs sound! So clean and calm.

[@doma3058]

Hey man, I really appreciate you and your videos. I used to dream of being a game developer when I was younger, and your videos were my obsession. That was probably around 2015-16 when i was 11-13 years old! Now I am in college for Cybersecurity and am so happy to start watching your content again! Thanks for sticking around man and I am real proud to see how far you have gotten. :)

[@ocleidyreve6361]

Uff Amazing video...technical videos also rocks and people like them. Thanks for taking some of our advices!!

[@mrcingo]

the fact that the sun is literally kissing you while you're coding is incredible

[@AlexScotton-Illizian]

Congratulations, this really adds a great layer and makes it so much more immersive. The way you've created the procedural sounds is genius and applicable for much more than an audio system.

[@Aquillyne]

Those procedural sounds are incredible! Bravo.

[@turnrp]

I love these devlogs

[@OnlyTheVerse]

I'll watch your every single video at least until you finish a city building game, you have my word!

[@ianbryant]

The procedural sounds are beast my dude.

[@wiechciu0]

That's impressive how well all of these parts work together. The procedural audio sounds really good, neat idea!

[@kacper2246]

i always find it incredibly impressive and admirable when someone creates their own game engine for a game love how the game looks, keep it up!

[@JohnDoe-bo5yk]

Ohh.. making your own engine.. thought this was just a game devlog.. now I might have to go back to your first

[@KrAvE4KaRnAgE]

As a bit of fun, you could try recording real-world sounds of you performing these tasks! Also, adding a start sound may also be value for certain actions. Such as the sound of a spade hitting the dirt. Loving this series so much, thank you for sharing!

[@SvenGarson]

Oh yes - Great idea layering the sounds - Very satisfying to listen to

[@LasseRafnDk]

Procedural sound (including the click sound) is such a nice QOL thing, makes the game feel so polished.

[@bonecircuit]

you can break the song in stems, intro, chorus, bridge and outro and then randomly play the chorus and bridge a few times in variations and cap them off with intro and outro. additional chorus and bridge chunks add to the dynamics

[@SpikeStudio]

Audio is one of the most underrated parts of a game, so its cool to see a Devlog about it. Great audio will not be noticed, but bad audio is heard by everyone, it seems you got a great start!

[@EdwardVarner]

Your solution to problems is always elegant and inspiring. I didn't expect to enjoy this style of video and I was sad when it ended. Well done!

[@Skeffles]

Brilliant to see how you are tackling sound. My last game had a bunch of issues with sound and I've struggled to find good videos explaining whats going on. This helped

[@marcruijs1039]

I'm currently working on making my own GUI library. Definitely taking some inspiration from this video 😬 Excited to see what you'll do with the UI!

[@TheHanutaXD]

I love the idea of the CompoundSound. Very neat :)

[@lightludology9081]

This is so inspirational! As a new viewer, I'm absolutely amazed!

[@RandomProduct]

I think that explanation of audio buffering explains how games with a lot of dialogue are able to have skip functionality. It'd probably be a lot jankier if it had to load massive audio all at once, quickly, every time you hit skip

[@rigolus]

I very much enjoy those more technical devlogs, do not be afraid to make more like that! :)

[@PultsMoizer]

Bro had the audacity to use Audacity. Great Video my man, really enjoying to see such a progress in more than a month!

[@cameronstroebel3333]

Very interesting episode, I enjoyed the deep dive :)

[@6ocram]

The procedural sound effects really give a lot of life to the game. Really really good implementation :D

[@SaadTheGlad]

Dude this is literally perfect, I wanted a good way to implement audio into my game and while it's not gonna be as complex as yours I wanna get some inspiration for future titles. Keep it up!

[@Draconicrose]

This is a really cool solution to the sound repetition and definitely adds juice to the game. I am thinking that as the player progresses so will the soundscape of the gameplay loop, which is neat.

[@coffeefingies]

The way you implemented the compound sound effects is really clever, well done. Might have to borrow that idea in the future!

[@CurtisDoesADig]

Dude, the procedural sound system is amazing! That was so awesome to see in action!

[@maxneevo]

The procedural sound system was such a cool solution, loving the videos!

[@ccoodduu]

This devlog was so interesting and useful! It's amazing how much sound does to a game.

[@feathorix8778]

I am quite new to your channel and I just realized that you do not "only" develop a cozy farming game, but that you use a self-made engine, too! That's so cool, much respect! 🙂 Seems like a big benefit in the current situation, hehe. I really like the idea of the compound sounds, they give a nice polish to the general sound design and make the tasks feel less repetitive. As another comment already mentioned, it could be nice to be able to hear the progress of a task, e.g. by raising the pitch after each tile. Very nice devlog! :)

[@natgazer]

You inspire me so much! Despite I'm more towards meat and stuff, I'm loving your game development!

Hey, really like your videos and the games you produce :) I also really enjoy the details you add to your videos like playing the music in the background the way your are describing it in the code :)

[@Genesis8934]

Random clicks sound cool; equally cool might be a step the pitch (up to a limit) in ascending or descending order. ;)

[@seb-astian-design]

Love the procedurally generated sounds! Cool way to create it! Have u thought about raising the pitch when u dig a hole? Idk it just felt would make the pop more satisfying.

[@robvp71]

Super inspiring and the way you structure your work.. impressive!

[@CaelCerf]

Wow, please talk more about the engine. Would love to hear more about it.

[@Hessrs]

One suggestion (that you may have already done but it's hard to tell) is if you click to perform an action such as digging/planting, if you don't let go of the click but move the tile to another valid tile, that the action still performs so the user doesn't have to click each individual tile. I think this would be something that people probably won't notice if it exists but definitely would notice if it was missing. Love the technical video though!

[@ThinMatrix]

Thanks! And that's already how the tools work :)

[@gernivisser593]

I love these more technical videos !!

[@dentjoener]

Amazed to spot an eclipse user in the wild 😁. Game's really starting to shape up, keep up the good work!

[@thehen101]

you should add a retry to creating the openal context(s), sometimes it seemed to fail for me for no reason when the CPU was under high load, but worked when retried

[@adrianozuna875]

1:47 "OpenAL library" => open audio library library.

[@heandog6481]

Don’t know the exact style you’re going for, but I feel like the game could be more relaxing with a less realistic style of sfx. I’m thinking more in the realm of mini motorways where it’s calming little blips and bloops that make the game somewhat relaxing and satisfying. Anyways, the more technical devlog was awesome and I really enjoyed this episode and the way you showcased and explained parts of your thought process and code!

[@j3ns]

I love these technical devlogs 😀 but I also enjoy the other ones 😊

[@lipsach]

Is the song buffering really needed, cos the song file is like 5-10mb? Isn't that rally small amount of memory now?

[@MrFredber]

I think, there is the problems with 3d sounds. 2d sounds are playing in both channels (stereo) normally, but all 3d sounds (like watering, digging, etc) are playing mostly in left channel. Right channel is mostly empty, so the feeling of the sounds is not very good. You can hear it very well in your headphones.

[@KestrelQ]

11:50 I can't be the only one who enjoyed this, right?

[@360McCarthy]

Can I just say how much I love these more technical videos! I was curious also @ThinMatrix what Java version and lwjgl version are you building the game using?

[@artembordiuh2802]

The sound system and sounds are great, most of them in my opinion are production-ready (unless of course a different feel is intended for the game). The only suggestion is the UI click sound, it's a bit loud and intrusive, and some of the sounds are spatially shifted when using earphones

[@kyaniteschmidt7658]

1:27 very smooth!

would great if you share how you're using Trello to manage the planning and development. Thanks again for the great content and beautiful game , all of the best.

I always wonder how do you have such a full Trello board and forward thinking plan, it'd be great if you explained ur planning process to us meer mortals.

[@triplezgames3882]

The sound effects sound great! Would there be a way for sharing them? I would love to use them in my game

[@dentjoener]

I'd never use linked lists, for stacks and ques I'd use an ArrayDeque. Less memory use and same speed

[@Szczurek15]

I'm in programming since I was 14. This will be 18 years now. It's not like I have spent those 18 years programming (however, in the hindsight, I wish I did). Nevertheless, I could be sitting there for a month and would never figure it out, that repetitive sound is annoying me, and some procedural generation is required. 😐 You da boss!
