@stackabydev LearnOpenGL is also where I first started! It's a great resource. The part I struggle with is what comes after: scaling up from basic rendering to having a full scene. Currently I'm trying to tie networking into the whole thing

@sleitnick I've been wanting to do the same. Began going through the learn OpenGL book. Where did you start?

I've really been enjoying my dive into graphics programming. Endless cool stuff to learn. I am flailing around, trying to understand as much as I can. I have so much respect for the experts in this field; they're real-life wizards.

Little walk in my little indie game village

@SondreMOTE Such a good idea. Wish I still had my PS2

Built a mini-PC inside my broken PS2, I just love the vibe of it

This weekend, I'm going to start my networking layer for my game. I'm excited! I've got half a dozen articles to read through. My goal is to build this from scratch (on top of UDP). I know there's a million open source libraries for this, but what's the fun in that?

@lanternenjoyer1 I am a game developer

@sleitnick you are a sociopath

You can use the quadratic formula to make homing missiles properly lead and hit their target. I've used this in games for like a decade. I wish they'd use examples like that in math class. Give practical/fun examples. I hated math b/c it was too abstract. Gamedev made it fun.

@Roverboby_2 Thanks 👍

@sleitnick You hated it because you're dumb and a bad human being.

@FFairing Not in a video game vacuum!

@sleitnick erm dynamic atmospheric conditions would make a quadratic unusable, no?

@campedersen I love working with PIDs! If I wanted to properly simulate the missile steering capabilities within physics engine, that's the route I'd go

@sleitnick Now do PID

@JohnDPMorgan Well, consider this as my way of doing so. I have no channels to talk to the math teachers of the world, nor am I qualified. How would you go about that?

@sleitnick Isn’t the problem that *you’re* not giving this example to the maths teachers? How are they meant to know about this?

@alexschultz002 Yup, very true. Pronav is the answer usually. I just thought this would be a cool example of lead prediction for demoing quadratic

@sleitnick Really... Most simple missiles just try to keep the angle between trajectories accute and unchanging. This guarantees a hit while keeping everything simple.

@plasma_node Ha, and it was just a dumb demo I put together in 10 min because I was locked out of Unity for a bit

@sleitnick congrats

@RougeAash I am literally a game dev

@HamptonTeach Yeah, so many different learning styles

@sleitnick Totally agree! But but for every student that is energized by that idea, there are likely 10 that either couldn’t care less about that application or are actively repulsed by that application. It’s a tough balance to achieve.

@lemonodor Oh that's awesome! Now I feel compelled to try to make something like that

@sleitnick You might enjoy ciws.obliscence.com

@nullp0ster @WallpaperKeith Oh yeah, I just rerun the exact same algorithm every frame. It helps correct things a bit, but it's not technically "correct" since it fails to consider angular velocity of the target (maybe there's a trick for that)

@sleitnick @WallpaperKeith yours actually does auto-correction though, the projectiles for mine just travel in a straight line regardless

@nullp0ster @WallpaperKeith Yes that is pretty close to what I have

@WallpaperKeith @sleitnick something like this probably (old code from my old project)

@anxious599 Yes, quite a lot when physics engine is involved. However, there's lots of stuff that's skipped. E.g. filtering out for errors is usually not as necessary due to perfect readings

@sleitnick Is control theory used in gamedev ?

@krilixe That's fine, because it brings those concepts into reality. Listening to a professor jabber for an hour and write equations on a whiteboard doesn't click for me. I'm a visual learner, and things like this help those concepts click for me

@sleitnick if u stick with it u get a trillion practical examples that are more realistic than this and require all of that "abstract" learning.

@asimo3089 My missiles back then used a simpler approach using time/distance/speed equation: - Measure time it takes missile to get to current target - Reproject target into the future by that amount of time based on its speed - Aim missile at that target instead Worked pretty well!

@sleitnick I remember building a castle in Roblox for History. Taught me more than most class projects! And some of my earliest Roblox memories are using bodyforces to create homing missiles, inspired by the plane games you made at the time. ❤️
