No significant improvements have been made to my engine since the last time I posted here

But I am writing my own vector/matrix library for personal use so I can remove one dependency from my engine, specifically GLM

>>105753097
Nice one anon.

I'm working on implementing a simple yet robust input event -> game action system.

Simple enum with different input events (e.g. SelectDirection, PerformDefaultAction, OpenActionMenu, OpenInventoryMenu etc) bound to certain physical inputs (eg PerformDefaultAction mapped to Z-key and A-button).

InputManager passes state of input events (not physical inputs) in the current frame to the PlayerInputSystem, which runs it through the GameActionResolver with the game's state, throwing the game action in the action queue, to be picked up by the ActionProcessingSystem. E.g. if the tile next to you is selected and player presses default action, queue a MoveAction with the direction parameter.

Translation layer will map the input event to a contextual game action.

I'm probably overengineering this, aren't I.

>>105753237
>I'm probably overengineering this, aren't I.
Yeah I just keep a mapping of all the keyhits and keypresses and just pull from that wherever I need an input state

Give some insight please. How did you guys got into this stuff? How did you first started learning programming? How did it evolved into game/engine development? Do you have other stuff on the side, like web dev, to make money etc? Is it even possible to focus both on game dev and other stuff?

>>105754910
I started doing it when I was 8 years old with QBASIC

Learn the basics first. If you want to be a good programmer, you've got a looong road ahead of you.

how did you even manage that?

my crimes are disabling warnings i dont care about

I added skirt to my chunk, the other option is to have half resolution border for the chunk to match lower lod but its a mess

Spent some time trying to give my variables better names, and realized I'm using:
>snake_case for variables
>SCREAMING_SNAKE_CASE for constants and macros
>camelCase for functions
>PascalCase for structs
this is just what feels normal to me, but now I'm wondering if there's a standard way to name these things in C

Working on our river shader + watermill and it's foley https://streamable.com/phxsvs

>>105755956
Years of disabled warnings until switching to debug mode which has them enabled.

OK so VSCode intellisense can't handle c++ modules so a workaround is necessary
#ifdef __INTELLISENSE__
#include "LinearAlgebra.cppm"
#else
import LinearAlgebra;
#endif

Include the module with regular #include for intellisense, but disable it and use "import" when compiling

>>105756957
i only get about 5k warnings if i enable all of them. no way im gonna litter my code with casts just to fix the "possible loss of precision," "sign mismatch," and the "function inlined"

>>105756831

I finally got shadow mapping working. Was a giant PITA. I settled on using push descriptors for getting the light depth image to the frag shader instead of allocating an entirely new descriptor set for render targets. Unfortunately renderdoc won’t run when the push descriptor command is called, the app closes immediately. Luckily nsight still works but I’ll have to look into that.

Bump

im gonna do it im gonna make a video game right after i finish reading one piece starting from chapter 1

>this month
Working on Object Oriented Bounding Box collision. But the [i]simple high-school level math[/i] was too hard for my elite hacker brain, so I am doing planes ("half-spaces") instead. This roughly doubles the amount of math for the CPU but also the code is less confusing. (Actually I think the problem's been floating point precision.) My intent is basically to hard-code reasonable behavior. Yesterday I got sliding-along-the-plane-when-its-at-an-angle working. I've had elevator-type motion working, and thought to try pushy-pushy motion. You stick to it which is reasonable for an elevator but not for pulling. But a more serious problem is phasing through it as depicted here. But the endless sinusoidal motion, it gave me nausea. So today I work in debug cam.

Also what you are doing is practically engine dev anyway
>>105760928
>How slow is [gdscript]?
It's pretty fucking slow. This code takes 0.3ms (on an i7 10700) for 512 particles which is a bit ridiculous IMO. GDFluid is a class I made in a C++ module.
for i in fluid_sensor.get_particle_count():
var particle_idx := fluid_sensor.get_particle_idx(i)
var pos := GDFluid.particle_get_position(particle_idx)
var vel := GDFluid.particle_get_velocity(particle_idx)

var dist := (pos - global_position).length()
var strength := maxf(0.001, ATTRACTION_RADIUS - dist) / ATTRACTION_RADIUS
strength *= ATTRACTION_POWER
vel -= delta * 5.0 * vel
vel += (global_position - pos).normalized() * strength * delta
GDFluid.particle_set_velocity(particle_idx, vel)

>>105762638
>what's the point of the language then?
It's usually fine except for large loops like that one

>>105762638
What tutorial are you watching that has c#? It should be gdscript for top level and c++ for behind the scenes.

I have abandoned the concept of frames entirely. My game runs in continuous time.

I have abandoned the concept of 1D time. My game runs in continuous complex time.

I have abandoned the concept of continuous complex time. Time is clearly three dimensional and I can blame all the bugs and jank on gravitational waves and quantum spooky action.

The fucking gall, the absolute chutzpah this guy has to sell courses and mentorship programs when his years of doing anything but making actual games is all there for everyone to see.

I genuinely don't understand how you can spend that much time programming and not reach a base level of competency where you could make a little indieshit demo and not have it take you years

probably because he doesnt really care about finishing a game

anyone have good resources on how people do tile blending (like terraria, or more specifically the CTM stuff for minecraft)

Sounds like a good move. A 2d pixelshit game should consume 2d pixelshit system resources. You make it in Unreal, Unity, or any other engine and you're suddenly using 8gb of memory and your GPU sounds like a leafblower just to render Mario Bros.

My C compiler is smart enough to optimize all the "variable++" in my iterators, right?
There's no way I would get a performance increase by going back and changing them all to ++variable, right?

>>105770136
>Sounds like a good move.
Yeah such a good move he spent the next 7 years not releasing anything before releasing a gamejam tier game that is barely bigger than that old UE4 prototype.

In such cases you actually want a table, not prosaic code.

tables arent always the solution for pretty code, consider
if(a <= x && x < b) { ... }
else if(b <= x && x < c) { ... }
else if(c <= x && x < d) { ... }
else { ... }
using a table here means doubling the size of the code

>>105790326
hell yeah dude tell us more about your project

GEDG seems like such a waste of time. Everyone is just working on their own game engine and no one collabs, no one here will ever do anything better than the game engines that already exist by themselves and will spend all their time trying to re-invent the wheel. If everyone worked together maybe something cool could be made but that would never happen and I doubt anyone would even agree on what language would be best to use.

>>105790410
Maybe it's a good idea to draw more attention to /agdg/ in the next new thread. Like my dumbass just popped in here because it was the first result in the catalog, when my first post would've been more appropriate for adgd.
Or maybe split the two generals into one for game dev and the other for engine dev. Instead of them both technically being game dev generals but one includes engines. I imagine there would be more collaboration efforts to make an engine than a game because of their future use vs a one off game.
I haven't looked into the game jam shit though but that's also an option

>>105790562
There is zero incentive for people to collaborate

>>105790562
bad idea, this gen is slow enough to accommodate both game and engine devving.
nothing here is stoping people from collabing, other than themselves

That's retarded. All the engines people actually use have big amounts of people working on them. Even smaller engines like Godot
>>105790474
>if anyone wants to work for free and do exactly what I say without having any input I'm quite happy to have you contribute.

>All the engines people actually use have big amounts of people working on them
Yeah, these are big engines made by professionals
If two clueless indie programmers collab they will literally be half as productive together as they would be alone

>>105790657
Best case scenario, they still won't do 1 or 3 for me

>>105790657
Engine "features" don't make a game. My stripped-down 3d game engine is objectively superior to unreal/unity/godot *for my use-case*. You always lose something with general-purpose.

>>105790657
these threads kind of are a form of collaboration tho. It isn't just posting personal progress, sometimes it's asking for advice or personal anecdotes and shit like that

>>105790657
>Their engine actually having features instead of being indie dogshit that will always have no games lol
Engine dev doesn't need a million features, it's game specific. Dumb ass zoomie. I don't need half the features something like unity has bloated into it to fit all needs.

>>105754128
Came in here as a non-regular in this general to basically ask the same thing; I got some video recommended to me this morning that said to go with OpenGL over Vulkan because it's easier to learn and you don't really need Vulkan unless you're doing something really advanced. I still want to know what the /g/irlygirls ITT think.

>good resources for C only vulkan?
My uninformed guess is that seeples might be the move here simply because it's been the gamedev language for a long time before off-the-shelf engines came along in the mid-2010's and had C# dethrone it as the gamedev language. But if you really want to, I guess start with the C++ resources for Vulkan and then work backwards into a C-only setup once you get the hang of things.

>>105792219
if you are new to graphics programming, concurrent programming, or coprocessor architectures, you might not want to jump into vulkan

>>105792219
sdl_gpu gives you the best of both worlds imo, it's still slightly more complicated than opengl but pretty damn good abstraction overall and gives you a lot of the power of any of the modern graphics APIs

>>105790676

Anyone know if there's a C implementation of backroll-rs (https://github.com/HouraiTeahouse/backroll-rs)? I don't want to deal with making regular GGPO transport agnostic. Maybe I could make C bindings for the rust version? That sounds like a headache too.

>>105793134
Can you just use the C++ version mentioned in the repo you just posted?

>>105793163
I believe they're talking about the original GGPO (https://github.com/pond3r/ggpo), which is stuck using winsock2.

>>105754128
you shouldn't discount webgpu.
building from source is a bit of pain. but it's much easier than vulkan while keeping the same pattern of a modern graphics api
I don't know what sdl gpu is like.

>>105794644
SDL gpu is webgpu with the serial numbers filed off, "cycling" as a solution for multiple frames in flight, and no shitty WGSL. also it has actually shipped and has worse mobile support on Android, I think that's everything

>>105792219
vulkan is neat, it has new debugging tools that are opengl won't get, and you can't easily do RTX raytracing with opengl.
but opengl ES will last forever because Google Angle is how webgl runs on all browsers (and you can run C++ with opengl on the web with emscripten), and Angle translates GL es to DirectX, Vulkan, and Metal, so those tools that don't work with opengl will work through Angle (but the tool will think it's DirectX, and OpenXR for VR won't work with Angle because it replaces the platform API like WGL/GLX but OpenGL technically works on OpenXR but it lacks swapchains / renderview which could be a performance issue? and the lack of documentation / examples for Opengl).

>>105793202 (me)
Couple hours later and it turns out I'm retarded, it's much simpler to just set up a transport layer for good ol' standard C++ GGPO than try to integrate a rustshit library. I was unaware of the callback functions it had.
