I know what the problem is!

I am talking about the disappearing world names problem. It’s unbelievable. If you think of something long enough, eventually you’ll find the answer.

I could not reproduce it. The reports I had were scarce (massive thanks to everyone who took time to give me info, some of you even made videos – you know who you are). On the surface, nothing tied the reports together. It was hopeless. I tried it again and again on all my test devices (and I have a large box full of them) – could not reproduce it on anything, from ancient 2010-vintage phones to Nexus 5. The only difference my 1.26 changes made were to load world information on a separate thread, to let the UI display the “scanning worlds” dialog.

The screenshots and videos of the problem you sent me showed that sizes and dates of the worlds are determined correctly. Only names and game modes were screwed. This was some lead. I looked through the code and located a likely place where it must be going wrong to produce this exact effect.

The problem is, it had no right to go wrong in that place, or anywhere else. It was the same code as in 1.25.

Then it dawned on me, literally just minutes ago. For those of you who have no idea about programming, the below explanation will make no sense, but I have to write it anyway. Sorry :-)

It’s the thread locale. Old enemy. When creating the thread I forgot to set the locale to invariant. All string operations (e.g. parsing of numbers) are then done using the system’s locale. In some countries they use a comma (,) instead of a dot to separate fractional part of a number. Because all numbers in the project file are saved with dots, the parsing of numbers will fail. This will only happen if your device language is set to non-english, and your country uses commas.

I confirmed it by changing system language on my test phone. Immediately got blank names. Lovely :-)


Trivial to fix. Obviously, after the fact you can see that all the bug reports are from non-english people…

If anytime again I have a bug that I cannot fix, please remind me of thread locales. Lest we forget.

          Wait, cooking eggs and bread is the same principal as cooking bacon or fish. So back to my original question.
          Why isn’t eggs or pumpkins in the food section of the recording recipedia?

    I had that problem before but it’s only happened like 2 times but it wasn’t a big deal. I just clicked on it and played it and it was back to normal. I’m sorry Kaalus, I didn’t know it was that problem. I thought it was literally world names disappearing, like this: One day, World name was “Super”. Next day it was gone. (Like it was just a blank). That was just an example of what I thought you were talking about.

    Cotton is so common. :) And pumpkins, you can finally farm them. There is a piranha lake under my house so whenever a predator goes there, it dies.

    Kaalus I have a suggestion. Can you make an option when you die you wont lose all your stuffs?

    Also, all people who are suggesting him to add bananas: You know that the bananas you eat are not wild bananas? Wild bananas are small and full of seeds. The bananas you eat are big and without seeds, they are human made. So unless the SC character knows how to breed bananas, then they can be added. But adding human made bananas to a place where there are no people is not realistic.

      It isn’t realistic to keep your stuff when you die, also it gives a challenge

    Kaalus, I have recently discovered a bug where I would be playing survivalcraft for 5-10 minutes and the words KINDLE FIRE would display just like if it’s rebooting or updating, but it my kindle freezes on that screen so I have to hold in the power button for fifteen seconds, then it reboots. This has happened to me twice and only while playing survivalcraft. It was on the normal kindle fire.

    ———————————–this is to get your attention of the bug

      There is a difference between hacking and modding.
      1. Hacking is illegal
      2. Modding is your choice not forced upon your game

      Modding isn’t illegal, people have made thousands of mods for all kinds of different games. So…

    Great job Kaalus! This update was amazing. A few suggestions:
    *smaller animals like rabbits, squirrels, or lizards
    * lightning rod prehaps?
    *More adornments such as flower pots, curtains, and maybe even the ability to place buckets on the ground
    * stained glass
    * Other crops such as rice, tomatoes, watermelon, corn
    *Mushrooms- most poisonous unless cooked!
    *More biomes would be nice, likr flower fields/hills and very thick forests with larger than normal trees

    You dont need to add these things though just suggesting :)

    I really want to play the update! Apple is taking to long! It looks awesome. But, A few suggestions to put in the game might be: •owls(a predator that can hunt birds) •Rideable ostriches •A search bar in community content •maybe llamas or alpacas please at least consider adding some of these. This game is awesome!

          Well I’m sorry to hear that you don’t like Apple differences. Sure it could handle that distance so so can my iPod touch 5 and so can my iPad Air without problems. I’ve seen that tablet up and personal and the performance is awful with horrible build quality, screen resolution and dead pixels everywhere. Just because it’s cheaper doesn’t mean it’s better. Especially in the android world where in that price I would just get a moto g which is a nice phone in that price range or a nexus 7 2013 tablet which is excellent

    Can we add ropes for the horses that we don’t have shelters for? It would be a nice feature, so is firewood! It would be such a help to have fires not use so much wood.
    Ropes are great for stopping horses from running off. If they aren’t killed by a tiger, then at least you still have your saddle!
