Has anyone else been stupid enough to start game programming by making their own engine?

Let's talk libraries, architecture and tool development.

So after a year in Java, then ditching it to rewrite in C++ another 4 months, my engine is finally coming together.

2d voxel game. All entities are voxels. Basically 2d Starmade.

Space partitioning:

unordered_map<uint64, Bucket*>

key = ix+iy<<32

People always say you need rectrees, but I find this works really damn well.

Trees without researcher-tier allocation are cache hostile as fuck.

This only has 2 dereferences/fetch. My impl is like ~30 lines.


Continuous so works at ultra high speed, but currently faster speeds need too much bucket gettings


Fuck torque calculations, All levers are of length 1 lol.


uuuhh.... "80% deterministic"

Basically fuck networking for now, I can't figure out an easy way to test this, and I do very continuous builds

>I can't figure out an easy way to test this

Since you're on based C++ now, then I'd recommend either POCO, Casablance, or ASIO. Since the standards committee will choose a variant of ASIO in C++20, that may be the best choice tbh.

so C#?

Why not use mono then?

The thing that's fucking me up hard is cross-cutting concerns. I.E., your program will ALWAYS be a tree if you use OOP, so when you have things on one branch that are needed by another branch you have to connect the two somehow.

I'm trying to remember what something is called but I can't remember it's name. It's where when you have multiple objects in a scene of the same time that instead of loading the same mesh into ram multiple times you load one copy of the object and have the data for each instance of the character or object that is being rendered stored into an array on the object. It's for rendering large numbers of the same enemy/character/whatever with less resources. I had thought that was called deferred rendering but thats for lighting. Does anyone know what this is called I can't remember it for the life of me.

And example of a game this would be useful for would be dynasty warriors. You have larger numbers of the exact same enemy on screen so rather than have a seperate object/mesh to call render to for each you have one object with an array contain the details of each entity such and their health, location, state, frame of animation, etc. Then you issue a render call to that one object so that you only have one render call instead of a separate render call to each entity.

In my day all we had were line number error messages and the single-step function and we were grateful.

That said, Lua doesn't have good debugging facilities, but it's not hard to gin up the output and control you need (well, it's not hard to gin up the output anyway).


I'm working on a game, right now it's all placeholder art because I can't draw. I have collision the way I want it along with movement and it's handling player health and knockback correctly along with player and enemy death and player attacks. I have almost all the functional bits of the game in place. Unfortunately I'm at a loss as far as level design, so I'm still using the little starting area I built. I'm also starting to consider making it top-down instead of side-on, but I'm not taking that very seriously, because it would make it feel very different and would make drawing and animating the whole thing that much harder.

I'm making classic grid based dungeon crawler with it and I've seen few rogue likes and even shitty pseudo-MMORPG.

It's not impossible nor hard but there's basically nothing as far as code snippets, tutorials or libraries go for RPGs so be prepared to pull out your favourite pen&paper rulebook and make everything from scratch.

7d26f1  No.27833


To expand on this now - I'm reaching the point of completion with the dungeon crawler and while my code is pure spaghetti and debugging is sometimes hot mess Love really isn't a bad choice for RPG since it really makes working with tables and arrays easier than when fucking in plain Lua.

What are some advanced books on writing a C++ game engine?

I'm looking for something like gameprogrammingpatterns dot com that actually walks you through making a full engine, the "right" way with best practices.

Not necessarily a 3D engine or with heavy physics, I'm mostly interested in the way it's structured, how it handles memory, best practices, scripting etc.

Bonus points if it uses C++11 or higher.

Marketing isn't hard. I have a mandatory marketing class in my graphic design course and didn't learn anything mind blowing. Just put yourself in the shoes of the consumer and think about where seeing your product would speak the most to you, and how it's best presented.

If you want to make banners and such: create some drafts, ask people you know for an honest opinion whether it would make them interested in seeing more. If it doesn't, start over.

Something that's incredibly obvious but people don't really realize is that most effective ads have a face or a character as the focus. That alone is not enough, but it's a start. The REALLY effective ads stick out and for that there's no guaranteed recipe for success, so get creative.

But honestly, the easiest way to market a game is just posting progress and interacting with people. The average person has a really short attention span, so an ad on some random website will be lost on most people. First impressions are everything and nothing works better than the recommendation of someone they know. Word of mouth is what you want to rely on, since I doubt you have the budget to launch a huge shilling operation (which can also fuck up said first impression because it comes across as dishonest if found out).

This is provided your game actually looks good. So put some effort into it, you lazy faggot.

I wrote a game in my spare time in MATLAB for some reason.

It was pretty simple.

You rolled a chracter based on basic D&D rules, but simplified and changed a bit. Then the king ordered you to find the dragon and kill it in some cave. If you killed the dragon, you returned to the king and he gave you nobility, if you convinced the dragon to leave, you returned to the king and was arrested for heresy, and if the dragon enthralled you, you returned to the king and slayed the king, becoming the new dark ruler.

If you didn't become the new dark ruler, but became a noble, the next stage of the game was to find a waifu, convince her to settle down with you, by going out on dates. If you got her, you won the game. If you were a prisoner, the next stage was to escape and leave the kingdom forever.

can i make an engine and know my shit going in this direction or am i squandering time? i want to build an engine becuase there aren't any that do certain things that i want, like destructive physics, verlet integration for hair, and so forth. i wanted to try and make my own so i can include it.

thoughts? i want to make a 3D game engine, and then a 3D game with lush hair and clothing movement, and character customization where one clothing mesh can be used on both genders by stretching to the hips and bust, due to the physics API. afaik unity and unreal don't offer this, so i'd be me shooting in the dark.

Pretty sure these things already exist as plugins or at least libs.

if you're still raring to go after watching those then I wouldn't worry too much about which engine to use. just pick one that's easy to learn with a big community behind it for support. it's not really practical to find the "best" engine for your game, at least until you're personally familiar with all the pros and cons, and that comes with experience.

>too much money

Only idiots spend any more than $5000 on a mid-scale project. Use free software, learn a few tricks about each field yourself, and get some low/mid poly art rolling off your free time, then hire people using Blender to work on the bigger stuff for cheap (about maybe $100 a mesh)

So while you're making yourself barrels, crates, and guns, they'll be making people, animals, and cool autistic machinery.

I sincerly don't mind making any money out of it. I don't play any vidya-game or anything. I just try to make it for fun, it's the only fun thing I'm able to do alone. I, to this day, never finished anything and I kinda feel bad about it. Though it is not a requirement to recognized for my work, I just wish for someone to appreciate my work. All I want is a "that's nice" from a none-programmer. I envy this feeling. All I do is only able to give me recognition among other classmate that look to my screen and sometime a teacher or two because they rarely seem anyone really enjoying programming in this decade.

Put the hearth you got during your childhood in your game. Don't do something simple, nor to complicated, express yourself. Isn't it an art in the end? Just keep on programming games, opportunnity will be more abundant in front of your eyes if you're getting better.

It seems like to me that the only way you can get anywhere in game development anymore is if you use your game as a soapbox for liberal propaganda (see: sjwtale, starjew valley, diary of a spaceport tranny).

How do you sell your games if they don't pander to the liberal propaganda machine and as you say, don't need to get featured or reviewed?
