and how you control these variables like position, view angle and collision box and stuff? they are all LA anyway

Well they will be tutorials

Abimbola

Algorithms is a must to be honest. You need to know the optimization strategies even for simple games :_:

Sounds hard and boring

Depends on school

It's here like that at least. It's more of an explorative journey since students don't really know " what their interests are" without giving it a try.

klimi

I have interest in all

Mar!o

You are not gonna write your own physics engine. You might use NVIDIA Physics or Bullet or Havok or whatever... quaternions and vectors - just learn how to use them no need to understand them fully (especially quaternions)

Abimbola

I wanna play some games so please before I come back don't give me 1 million messages

I glanced over cpp after going through rust, and xD, there are a lot of similarities. The book referenced c++ a lot.

True

but ray tracing have huge root in physics, like ray refraction and surface detection and diffuse and stuff, these are returned as a ray tracing result set how do you use them if you dont know them?

klimi

Ray marching is quite interesting I want to try it someday

Mar!o

but ray tracing have huge root in physics, like ray refraction and surface detection and diffuse and stuff, these are returned as a ray tracing result set how do you use them if you dont know them?

I don't think he will implement runtime raytracing via Vulkan or D3D12 if he wants to build a simple games lol

Stefan

ray tracing might also involve something like shaders and PBR too

Stefan

I don't think he will implement runtime raytracing via Vulkan or D3D12 if he wants to build a simple games lol

but you want to make a game and im telling you how to lol...

Mar!o

Of course in AAA engines there us lot of math but he talked about simple games...

Mar!o

PBR does not require raytracing. But some effects like ParallaxOcclusionMapping use a similar technique...

Stefan

lol knowing quaternions mean you know how to map complex numbers to 2d coords

I think it's better to start from the basics. You can always dive in deep if your specifications get deeper. Step by step :)

Parra

No one uses C for games

I did a game engine for MMORPGs in C

Mar!o

Also there is much more to an engine than math: it is also hard to write a real parallelized ecs. There is also an engine kernel, runtime system, maybe a VM

Mar!o

I did a game engine for MMORPGs in C

I meant big AAA engines. I like C too but a missing stl sucks when developing games

Stefan

PBR does not require raytracing. But some effects like ParallaxOcclusionMapping use a similar technique...

well but it will affect the direction a ray might deflect, like if you have a metal surface it will shine and stuff

Parra

I meant big AAA engines. I like C too but a missing stl sucks when developing games

well, AAA engines are monsters, for sure they aren't written in one language

Nils

It's suspicious

Why? Perfectly fine to me, I have heared good about the developer

Parra

when you are learning, it's cool: https://bitbucket.org/parrastudios/argentum-online-c/src/master/common/src/DataType/

Stefan

ue4 is written in c++, but heavily modified... cryengine is c++/mono c# hybrid frostbite uses c++ a lot too i guess unity, well unity is not aaa at all

Mar!o

well but it will affect the direction a ray might deflect, like if you have a metal surface it will shine and stuff

But at least AFAIK even PBR uses traditional Lambert or gouard for specular lighting. It reads the values from a roughness map and uses a modified formula.

Parra

ue4 is written in c++, but heavily modified... cryengine is c++/mono c# hybrid frostbite uses c++ a lot too i guess unity, well unity is not aaa at all

yeah, that's the point, and who knows what uses RAGE and friends

Stefan

but let me tell u what, source engine is utter garbage

Parra

they mix many technologies and engines in one

Stefan

yeah, that's the point, and who knows what uses RAGE and friends

still c++ but with reflection system same goes for anvil in rb6

Mar!o

ue4 is written in c++, but heavily modified... cryengine is c++/mono c# hybrid frostbite uses c++ a lot too i guess unity, well unity is not aaa at all

RAGE from GTA V and RedDeadRedemption2 uses C++

Mar!o

No it's just old and has never seen any big overhauls

Stefan

No it's just old and has never seen any big overhauls

i got the leaked source code and i want to f__king puke

Mar!o

The source code is on github

Mar!o

It is open source. Search for sourcesdk2013

Parra

i got the leaked source code and i want to f__king puke

well, I understand them

klimi

but let me tell u what, source engine is utter garbage

Yandere :D

Parra

they had to do that in record time

Stefan

i got the leaked source code and i want to f__king puke

like is this 15 years of diarrhea s**t

Parra

code quality wasn't a priority

Mar!o

Traditional

Stefan

It is open source. Search for sourcesdk2013

no that is just public interface, i mean the real source code with cpp files that hides the engine quirks

Parra

also source was the first to introduce discrete simulation which for me it's something huge

Mar!o

PBR just uses fancy maps and formulas to keep the material appearance more realistic in different lighting situations...

Stefan

also source was the first to introduce discrete simulation which for me it's something huge

actually no, game console have ragdoll physics long ago iirc

Mar!o

no that is just public interface, i mean the real source code with cpp files that hides the engine quirks

No it also contains the rendering code and stuff. Sure some stuff is hidden because of security

Parra

actually no, game console have ragdoll physics long ago iirc

I mean discrete simulation in multiplayer

Parra

they have the paper, you can check it out

Stefan

I mean discrete simulation in multiplayer

...state machine replication just

Parra

how discrete simulation is related to state machine?

Stefan

how discrete simulation is related to state machine?

you replicate the server physics state to client iirc

Stefan

but client then will do physics prediction only, hence it is actually approximated

Parra

the concept of discrete simulation is breaking the time into quantums where you can rewind or apply vector clocks so you can synchronize distributed systems, this is something decoupled from physics

Parra

although both can be used combined

Parra

with this methodology you turn the whole engine into a reactor, that can be modeled by events

Stefan

https://developer.valvesoftware.com/wiki/Source_Multiplayer_Networking damn i havent read this like 2 years

Stefan

with this methodology you turn the whole engine into a reactor, that can be modeled by events

it feels more like control in control theory i think

Parra

it feels more like control in control theory i think

I don't know about it

Stefan

I don't know about it

game engine is essentially a feedback loop

Stefan

time dependent

Parra

I have worked with similar sistems (to Discrete Simulation) and it's quite clever, those kind of architectures are really interesting for any kind of realtime systems (not only games)

Parra

by things like this is why I respect source, although the code could be a complete mess due to time/commercial restrictions

Parra

right now I'm in a project which is applying this kind of things to implement a compiler that can make js code threaded automatically

Parra

and I mean real threads (multiple js threads), not I/O

Stefan

right now I'm in a project which is applying this kind of things to implement a compiler that can make js code threaded automatically

its a np hard problem, job shop scheduling

Parra

anyway, it's cool, I enjoy this kind of things
