      ATTENTION Forum Database Breach   03/04/2019

      There has been a breach of our database. Please make sure you change your password (use a password manager, like Lastpass).
      If you used this password anywhere else, change that too! The passwords themselves are stored hashed, but may old accounts still had old, insecure (by today's standards) hashes from back when they where created. This means they can be "cracked" more easily. Other leaked information includes: email, IP, account name.
      I'm trying my best to find out more and keep everyone up to date. Discord (http://invite.gg/TerraFirmaCraft) is the best option for up to date news and questions. I'm sorry for this, but the damage has been done. All I can do is try to make sure it doesn't happen again.

Time Scaling in Single-Player

7 posts in this topic

Multiplayer obviously has its own pressing needs, but I discovered something interesting the other day I thought I'd share.

 

Clearly, Minecraft is scaled down from the real world;  you can walk across a biome in a day or two, to name just one thing.  But just as obviously, the scaling isn't linear.  One Minecraft day is clearly supposed to correspond to one real-world day.  But a Minecraft month is only 8 days, while a real-world month is about 29.53!  The scaling must be logarithmic or something similar.

 

So I worked out what it would have to be.  It turns out that a factor of 10 in the real world corresponds to a factor of about 4 in Minecraft.  (4.114, to be a bit more precise.)

 

With that in mind, how long should a year be?  It turns out to be close to 37.5 days.  TFC requires a multiple of 12, so let's round down to 36.

 

Each year is then 4.5 months long.  A season is 9 days, a month and a day.  The growing stages of plants are incremented in 3 day periods - which corresponds to very close to 6 real-world days, so let's call them weeks.

 

Going in the other direction, the day should divide into about 7 hours to match the real-world's 24.  But that's hard to work with, so let's call it 8.  Each of those 8 hours should divide into 10.8 minutes - call it 10.  And each of those 80 minutes should divide into about 13 seconds.  But if we make it 15 instead, then a Minecraft second exactly equals a real-world elapsed second - obviously a desirable thing!

 

I'm tempted to expand this into an exploration of the effects on the laws of physics, and I may yet do it... it might well end up explaining how Steve can carry so much, among other things. :)

Looks like a lot of time and effort went into this. :P Good job, pretty interesting!

There is an option in TFCOptions.cfg (The Config File) to determine how long you wish for your SSP month to be in days. So technically, year length is entirely configurable.

Guys, my tongue was at least half implanted in my cheek.  I do feel that 96 days is too long a year for single-player, though;  and it was gratifying to find that the (unintentional) scaling of the vanilla game suggested I was right.  (And while I'm flattered, Soboy007, it didn't really take very long - a few minutes with a calculator.)

 

It would also be possible to approach it the other way 'round...  Notch has long since said that one block is exactly one meter.  So if one assumes that the second is treated the same way - one in-game second is one real second, and ditto for the day, one arrives at an 'ideal' month length of 8.26 days.  So in some sense the 8-day month is 'right', for whatever value you choose to assign to 'right'.

Oh, and I just looked and don't see the option to change the month length?  Am I missing it somewhere?  I do see the day-length and year-length options.

Changing the year length changes the month length at the same time. 96 days in a year means 8 days in a month. So if you increase that to say 144 days in a year, that ups the month length to 12 days.

Got it, didn't know that.  Thanks!
