Example spreadsheet of Vaporum game data.

Dark theme for the win!

Let’s get straight to the point!

Spreadsheets are excellent for setting and tweaking static game data. In my experience, nothing comes even close to the speed and convenience of spreadsheets, with all the modern editing capabilities. JSON, YAML, TOML, XML, SQL, they all fade before the king!



  • Baking game data into source code is outright bad! It’s typically hard to find any specific value and requires recompilation on every change.
  • XML and JSON are verbose and it’s difficult to change multiple related values quickly. Say, you need to tune down the health of all enemies. Oh well…
  • Full-blown database systems like MySQL are too heavy to set up and maintain, to my liking.


We’re using LibreOffice Calc (free alternative to MS Excel) to create sheets of data. All kinds of data. Enemy health, skill cooldowns, damage values, traits, attributes, you name it. The sheet is a perfect fit for this kind of tabular data — related keys of many elements. To update the game with the tweaked values, we simply export all sheets into CSV files that the game can read.


The sheet is typically set up like this:

  • The column marked with !MainKey is reserved for identification of the element. The game creates a dictionary entry for each cell in this column. !MainKeyVert is used for vertical sheets — the game processes them with a slight difference.
  • The first row are the keys. The game reads these keys and assigns the column entries to the given main key entry.
    • Most keys are standard, meaning that they repeat many times for many different game objects / prefabs / actors.
    • Unique keys are marked with !, and the game reads them in-line along with the value. This is the best we came up with for non-tabular data, e.g. keys that never or seldom repeat. If you have a unique skill that does something that no other skill does, the key for the value of that action is most likely going to be unique. So this is for that case.
  • The second row are nice names so it’s easy to understand what is what at a glance. This is ignored by the game. It’s only presentational.


As I mentioned, we save all the sheets from the doc into CSV files, so the game can read the precious data. But, it would be horrid to manually re-export every sheet to a CSV file every time you changed a value. LibreOffice script to the rescue! It exports all the sheets to CSV files whenever we save the doc. The game then simply loads all these CSV files into various static dictionaries. Automation for the win!

Other parts (characters, skills, attribute banks…) then simply read the values from the proper dictionary by a key they get from the prefab name (or whatever suits us).

The loader class can be as simple as this:

If you don’t feel like writing your own or using ours, there are good libs out there:

We also have a neat class to manage the static dictionaries, to help retrieve values from it, but I’ll leave that to you to come up with. Don’t wanna get spoiled too hard, right? πŸ˜‰

Unique keys go into the cell as a key-value pair.

Unique keys go into the cell as a key-value pair.


We were using our own, simplified implementation of YAML for all game data, but that became a chore to maintain. The number of elements just grew too much.

Once we created this sheet data flow, it’s become a breeze to not only tweak, but also find and understand all the values at a glance. Shorter iteration times (tweak -> test) help a ton for any project bigger than Tetris! And besides, attentive readers noticed we had three ‘for the wins’ in the article, so it has to be cool! πŸ™‚

dice picture in vaporum article about randomness

RNG stands for random number generator. In this article, I’ll show you what kind of RNG we use in various chance-based actions in Vaporum.


One of the greatest RNG evils in games is long streaks of success or failure. Especially failure! How we hate to miss the attack 4 times in a row while the hit chance is 80%!

But why even care? We can just use this and be fine, right?

if (UnityEngine.Random.value < myChance) Hit();

Hell no! This most basic approach has exactly the one glaring issue: big streaks of luck or unluck (what a word). You will get them on regular basis. They are bad for your game.

Let’s see what we can do about them pesky streaks.


First, let’s see where we use RNG. Major chance-based actions in Vaporum are:

  • Weapon attacks (enemy attacks too)
  • Critical hits
  • Various on-hit passive skills and traits

To ensure consistent results of various actions, we have an instance of RNG on each of them. Every time an action is checked for success, based on the given chance, the RNG is polled for a result. It either returns true or false, success or failure.

Each weapon (enemy attacks count as weapons too) has two instances of RNG. One for hit chance, one for crit chance. Whenever you attack with a weapon, we check the hit RNG. If we got a hit, we then check the crit RNG.

Other effects, mostly passive traits, are only checked when appropriate. For example, if you have a passive trait that adds a chance to stun the enemy with hammers, and you attack with a hammer, the RNG of the trait is checked. If it succeeds, we apply the stun.


After trying out 3 various RNG systems (designed by us), we decided for the pseudo-random distribution (PRD) model. It gives us consistency of results, almost exclusively eliminates long unprobable streaks, but still leaves some room for occasional short streaks. You can read a fine article about it on this Dota 2 fan page.

The basic premise is that whenever your success check fails, the chance for the next check increases, and this goes on and on until it succeeds. And when it does, the chance is reset back to the base value. The base chance value is not the desired chance (as shown in tooltips for weapons and skills), but a pre-calculated constant. The first check is also run against this constant, not the displayed chance. Read that article to get a gist of it if you haven’t already.

Now the problem is, it’s hard to calculate that constant. As you can see, they have a pre-calculated constant for every 5% up to 80% in Dota 2. That’s fine for Dota, but not for us. We need constants for each percent, from 0% to 100%.

So how we get them? Approximation comes to help!

Note: The [VapSave] attribute is our fancy save system. You basically just mark anything you want to save and you’re done! Lots of work behind the curtain though! (More on that in a later post, hopefully.)

So, we just pasted the generated constants into a static array, and the rest is fairly straightforward I hope.

You can use the static Test function to test if it gives expected results for various chance percentages. However, that is just a guide. Only playing your game will show if it survives the battle-test!

Now, we need to create instances of the VapPRDRandom in classes that use chance-based actions, and just poll the Success method.

There are several ways to achieve ‘good’, consistent randomness without the dreaded streaks. For us, the pseudo-random distribution model works like a charm, solving the random issues we struggled with. Hope this helps someone out there, struggling with the same thing.

Already using a system that works for you? Do tell!

Game Access ’16 in Brno

Vaporum has gathered unprecedented steam in recent weeks, in terms of exposure at gaming events. As we stated in a brief post, we were going to present our game at Game Access 2016 in the lovely city of Brno.

That was one successful, strenuous, and inspiring indie event! We received overwhelmingly positive response from both journalists and the public, as well as loads of spot-on feedback on how the game plays, what it lacks, and what it excels at.

Reboot Develop ’16 in Split

But before we could even process all the goodness, we decided to go to Croatia for another gig — Reboot Develop 2016. With names like John Romero, Cliff Bleszinski, and Brian Fargo to give speeches, we couldn’t resist this big indie event!

Didn’t take long before people swarmed to our ‘booth’, bombarding us with countless questions while trying to beat the demo levels we’d prepared.

Atmosphere, graphics, and combat were the most praised features by people at both events. That makes us really happy, because that is exactly what we wanted to be the strengths of Vaporum from the beginning.

We’ll share details about how we fared at each event, what we’ve learned to do, not to do, and the pros / cons of presenting at such events in later posts.

Hey folks!

Here’s a new video to show the current visuals of the game, which we started working on when going full-time on August 2015.

The biggest change in graphics we did since prototype was switching to PBR (physical-based rendering). We are using PBR Alloy shaders for Unity done by RUST Ltd. The shader pack works very well together with the pair of texturing tools — Substance Designer and Substance Painter from Allegorithmic. These allow us a fast and robust way to create textured assets that share the same basic materials from our own library.

3ds Max, Maya and Zbrush are the usual suspects we use to create models. Since full-time development started, we have also raised the polycount on our assets. This way we can achieve a higher visual fidelity and also give the game a more “eye-candy” feeling. For which we received awesome journalist and public feedback at gaming events we recently attended. (We’ll post about the events later this century. πŸ˜‰ )

Hope you like the video, and feel free to voice your opinion on our media channels.

Hey guys! Just a quick update on what we’ve been up to lately.

We did a focus test where we invited various people to come to play our combat test, most of them never having played the game before. We needed to see if we’re on the right track with the real-time combat, melee vs ranged, and various other features in it. Receiving basically universal praise from the testers boosted our confidence in that we had made the right decisions. Of course, the guys also pointed out some flaws, which we quickly fixed after the test was over.


We have about half of all planned enemies in the game, fully functional, running around doing nasty things (mostly to the player). The focus test proved we already have a solid bunch of bad guys where each has different strengths and weaknesses, poses different types of threats, and requires a different approach to beat (lots of differents, eh?).


All basic building bricks like trapdoors, pushable crates, destructibles, levers, teleports, and such are done. We also have a solid design on all the puzzles and game situations, which we build out of these basic bricks.

Inventory, items, and basic RPG system are also fully functional. We have several levels designed on paper, with major puzzles, situations, and storytelling. Our custom level editor allows us to whip up all the corridors, halls, and rooms in no time, so that’s gonna be a blast!

Right now, we are:

  • Enriching our RPG system with all sorts of attributes, skills, talents, traits, and whatnot.
  • Building up GUI so you can play with all the RPG goodies with ease.
  • Adding more enemy types.
  • Adding wallsets and architectural gems.
  • Designing more levels and ways to screw the player. πŸ˜‰
  • Designing boss encounters, plus the final big boss showdown.

We don’t post often, but rest assured we use all the time to work on the game.

Discuss in our reddit or other social media, share, and have a nice one!

Sorry to be quiet for so long. We’ve decided to post only about highlights or milestones rather than churning out insignificant posts often. Saved time will always come in handy! Nevertheless, we’ve been working hard on various game systems, levels, and some goodies too.

One of which is the Flamer Guardian. This badass giant of a man has few weaknesses, but a lot of firepower. As with most of our enemies, you will need to devise a tactic to beat him rather than just banging at his thick armor head on.


The Guardian is based on the concept art by Roman Mindek, who is currently working full-time on Kingdom Come: Deliverance. Check his portfolio here!

The big guy is modelled, rigged & animated by our in-house character artist Lukas Chrapek (who is also a big guy πŸ˜‰ ). Lukas is in charge of the technical side of graphics, besides his bread-and-butter work of character-modelling, rigging, and animating. He previously worked on various projects as a freelancer. Before joining the Vaporum team, he worked at Keen Software House as full-time lead artist on Space Engineers and Medieval Engineers. You can check out his portfolio here.

We have moved to PBR workflow in our project, and Lukas made a damn good use of it on the Guardian. Take a look at the Flamer Guardian in all his glory in Marmoset Viewer here.
