// Description
Mythfall is a fast-paced bullet hell MMO where skill and strategy determine survival. Battle relentless monsters, loot powerful gear, and grow stronger as you fight to defend your homeland from the mighty wizard Alivarg. Face deadly bosses, forge alliances, and carve your legacy in a world where every fight could be your last.

We currently have a pre-alpha demo on our website. You can play directly in your browser!

Face Relentless Bosses

Every boss fight is a high-stakes showdown where survival is never guaranteed. Dodge waves of relentless projectiles, exploit attack patterns, and unleash your best abilities in a test of pure skill. One mistake could end your journey for good. Will you rise above the chaos, or will you fall like so many before you?

Hunt, Gather, Craft, Conquer

Every battle earns you resources: Rare materials, essences, and legendary drops. Forge powerful gear, enhance your abilities, and shape your character to survive this unforgiving world. The stronger you become, the deadlier your enemies - but every victory brings you one step closer to mastery.

Rise Stronger with Every Fall

Death isn’t the end - it’s a step toward greatness. Every time you fall, you earn Honor Points, unlocking account-wide progression that makes your next journey even stronger. Level up your legacy, unlock powerful bonuses, and prove your resilience. True strength isn’t measured by how long you last, but by how much you grow with every rebirth.

Other Features

Cooperative Multiplayer: Team up with friends or meet fellow adventurers in a world where cooperation is key.

Diverse Skills: Complete quests to earn skill points and refine your build for ultimate power.

Character Customization: Personalize your character with a variety of haircuts, colors, and cosmetics to stand out in the world.

Complete Achievements: Earn achievements and unlock exclusive chat badges to showcase your victories.

Openly Developed: Mythfall is actively developed with frequent developer livestreams and regular devlog updates, giving you an inside look at the game’s progress. Join the community, share your feedback, and watch as we shape the world together!

// Description
This is a brief overview of how stairs work in top down 2d game worlds. We can make the game look more 3D by simply adding a small Y bias as the player moves up and down stairs, making it look like they are climbing up, when in reality they are only moving diagonal.

Since I haven't been keeping up with a devlog on my MMO project, I figured I'd make a video covering approximately the last year of development building an MMO. I'm hoping to make devlog updates more frequently, so stay tuned for that. Also, I didn't really cover it in the video, but I decided to flesh out my OpenSource repo into a full game. So I'll be building the remaining portion of the MMO on a private repo. That said you can still find the point at which I forked here:

I'll also be maintaining some general open source libraries on GitHub. You're more than welcome to use them. But most are still a work in progress:

Golang Physics Performance

UnitOfTime 2022-11-01 | ⁍ Wishlist: store.steampowered.com/app/3475620/Mythfall

In this video I spent some time benchmarking my ECS (Entity Component System) framework against the popular Rust ECS, Bevy. We had to do some performance analysis and optimize a few things, but all things considered, we ended up doing pretty well. Specifically, we optimized by doing bounds check elimination (BCE), inlining, and using the recently released Go generics

// Good Article
⁍ PlanetScale: planetscale.com/blog/generics-can-make-your-go-code-slower

// Errata
1. Calling Monomorphization "The other end of the spectrum" from GC shape stenciling is a bit overblown. Go stencils (ie monomorphizes) its generics based on the GC shape, so there still is some monomorphization happening which can give you nice performance gains for things with different GC shapes. The actual "Other end of the spectrum" is probably something like doing a full dictionary-based boxing and doing no stenciling at all.

2. Why does Bevy Run Slower than Go?
I apologize for not covering this in the video. I think number 1 and 2 are probably the biggest contributors to Bevy running slow.
a. Bevy has A LOT more features than my ECS, each of those features might contribute to a global optimization for most cases, but in my benchmark contribute to a slowdown. I expect that most people aren't disabling multithreading and the system scheduler and manually executing every game loop.
b. Bevy has a few different layers at which you can use the ECS, I'm not a bevy expert, so I may have written the code in an abnormal way where bevy ran slower than it usually would have. Very specifically, Bevy seemed to slow down the more I started adding and deleting components, I'm not sure the limitation there, but I thought it was notable.
c. Bevy isn't the fastest Rust ECS framework according to this: github.com/rust-gamedev/ecs_bench_suite - I learned this actually kind of recently after all my code was written for bevy
d. Pointed out by laundmo in the comments:
1. "by default, bevy uses what it calls "Table" storage for components - this is fast to iterate but slow to update. In use cases where you might want to add/remove components a lot, you can switch to SparseSet storage on a per-component basis." - I didn't know this, but it does align with what I saw where Bevy slowed down once I started deleting entities every frame.
2. "The ECS benchmark [in errata C] you mentioned is outdated by 2 years, and was also recently archived to represent this. Bevy has had multiple optimizations since then. I see you using bevy_ecs 0.7 - in 0.9 there were some decent performance improvements which would be interesting to see."

Golang Gophermark #shorts

UnitOfTime 2022-09-28 | I was curious how the performance of Golang is impacted by using libraries through CGO. Specifically I wanted to see how the performance drops when I use OpenGL in Golang instead of C++. So I wrote a benchmark similar to bunnymark in Go and C++ to compare average frame times.

Literate(ish) Programming in Go

UnitOfTime 2022-08-16 | I was recently interested in programming languages and had the idea for building a blog which gets generated from experimental code. That way I can write some code and document it - Then compile it into a blog. Previously I've used Hugo to generate blogs from markdown, but it always felt redundant to copy-paste my code from my repositories into my markdown files.

How to code an AutoTiler (Easier than you think!)

UnitOfTime 2021-09-28 | Today we look at how I coded an AutoTiler for my base builder game Spruce - which is actually not that difficult. AutoTilers select the correct edge tile to render a blobmap of a specific tile type. Most engines like Unity and Godot support features just like this. To do something similar, we generate a bitmask based on tile neighbors and use that to look up the correct tile that we want to render.

Sharing systems between client and server [Making an MMO - E11]

UnitOfTime 2021-08-25 | ⁍ Wishlist: store.steampowered.com/app/3475620/Mythfall

Today we reorganize some more! The last reorganization (for now) is to add all of our client specific logic into shared packages so that both the client and server can share code when building their physics simulation. That said, input handling and rendering will still remain "client specific". Finally, we built a common struct which will represent our system. This way we can dynamically build arrays of systems and execute them as needed in our game loop.

There are some organizational challenges when building client server architectures. Namely, we will often be asking the question, "Will this code be accessed from the client, the server, or both?" So today we will perform some initial organizations to remove opengl dependencies in our server binary, we will also start moving our "game logic" code out of the client's main.go file and into a common location.
