Hey {{ Preferred First Name | Designer }},
Welcome to issue #6 of Signposted!
In this issue weāll be breaking down a theory on how the PokĆ©mon GO location system works.
In the best of series weāve got a stacked lineup. Starting with Dan Felder (Riot Games) discussing his take on game balance. Andrew Chambers (World of Warcraft) kicks off our video section taking a deep dive into Enshroudedās shroud mechanic. Followed by Masahiro Sakurai (Smash bros. and Kirby) discussing game rewards. And in the best of podcasts, we have Ben Jones (Battlefield 4, MAG, SOCOM 4) discussing live service games.
Last but not least, the results of last weekās community poll are in, Nintendo absolutely crushed the competition for top Japanese developer. With multiple 90+ Metacritic rated games this year, itās not hard to see why.
Letās get into it!
Bi-Weekly Analysis
A Theory on PokĆ©mon Goās Location System
By Scott Fine
The PokĆ©mon GO spawning system sounds complicated, but is quite simple once you break it down. Likely, a similar system is used for the recent Monster Hunter Now game as well. In this breakdown, Iāll run through a simplified example to give you an understanding of how it works.
As per usual after the link to the full article is a quick breakdown of the most important points.
Quick Takeaway:
This example is going to be a miniaturized version of how it functions so itās easier to explain.
Imagine a map of Los Angles, and over that map is a grid like this:
Within each grid space are a selection of up to 9 randomly generated PokƩmon the player can discover.
This is reflected by the āNearbyā PokĆ©mon screen:
When the player crosses to a different grid space, a new selection of randomly generated PokƩmon appear unique to that space.
This is controlled by the server so the player canāt just walk back and forth across the street spawning new PokĆ©mon.
Letās imagine there are only 5 PokĆ©mon options which can spawn + an option for no PokĆ©mon.
Pidgey
Rattata
Zubat
Growlithe
Goldeen
Now letās plug those into a drop table:
As you can see from our list there is a high chance of spawning Rattata, Pidgey, and Zubat because there are a lot of them listed on the table. But a very low chance of spawning a Goldeen because it is only listed once.
Every so many minutes one of the 9 slots will remove a PokƩmon from the list and use a random number generator to select and spawn a new PokƩmon from the chart above.
In this way there are always new PokƩmon to catch as they are constantly being cycled out.
Note: for those new to random number generators and drop tables it functions as follows:
A random number is selected between 1-20 and whichever number is selected the corresponding PokƩmon is chosen.
If I were to go into a grid space, and the random number generator ran the following numbers: 4, 1, 2, 17, 20, 1, 5, 13, 4 the 9 PokƩmon which appear in my grid space would be as follows:
Pidgey
Pidgey
Pidgey
Growlithe
Nothing
Pidgey
Pidgey
Zubat
Pidgey
But what about terrain, rarity, and the night/day cycle?
All of those simply adjust the drop table.
As you can see from the below image, if you were to go over water, many slots on the drop table would be replaced by Goldeen.
This dramatically increases Goldeenās chance of spawning:
If you take this basic idea and explode it to grids around the entire globe and all the PokƩmon, you have a basic idea of how it functions. For a little deeper dive and how lures and such work, please check out the full blog in the link above.
