Upside-Down Trapdoors

I am working flat out to clear the todo list for 1.19. During a little break, I made this video for you:

I am now adding features so quickly that I have a lot more done than I can show. Stuff for the next video is already in.

Unfortunately I may need to add one more thing to the todo list. I have reports of people losing their worlds on Android, due to a failed save. I need to add a fail-safe saving system that is more resilient to sudden app shutdowns, power losses and low on memory situations than the current one. Somehow it wasn’t needed on Windows Phone, but Android is more picky.

In the meantime, if you have a valuable world, please backup it to Dropbox periodically. You can also reduce the probability of the loss happening by:

  • Making sure that you exit the game when you are finished playing (go to main menu and press the back button)
  • Make sure that you have enough free internal space on your phone
  • Make sure that you do not run out of battery while playing

    This update is by far going to be the best ever! Although i did kind of guess that was what upside down trapdoors were going to enable us to do.
    When you said suffering for science that reminded me of Portal lol
    Other people say not to cram so much in this update but you should try to put everything you want electricity to do in this update so people won’t ask for more stuff later.

    Pulley system would be epic in a future update( to replace pistons) for pulling a block to the side or up. And for pushing upwards or side to side, a hydrolic system would be a pretty good idea.

      Motors would probably need to be added for logical reasons. And then the obvious feature of being abke to use a button, pressure plate, or lever to activate these things.

    Any chance kaalus of fixing it so that we can also paint wooden slabs and stairs? Great work on the update. :-)

        That would be awesome! I changed the paint option to create cushions and fabric. This would allow me to create furniture and chairs with the stairs and slabs. =)

    Hey Kaalus, I have android 4.0 running on an HP Touchpad, so I’m not sure if the problem lies with me, but I can’t upload worlds to dropbox on it. Anytime I leave the app (to go to the browser and allow the permission) and try to return, SC shuts down, and you start back from the splash screen. Doubt it’s a problem with the game, more likely just some android multitasking issue, but is there any other way to do it? Maybe an in-game browser?

    Thanks, looking forward to the next update.

        I had problems to until I downloaded it from my pc directly to my dropbox on the pc and then downloaded to my phone directly through the dropbox connected via my survival craft. I’m pretty sure its the phone itself doesnt allow the user to download png or scworlds because it saves them as html and not their intended file. Root your phone or either find an app -if one exists- that will allow you to save files properly. Otherwise do it through a pc through your local library or school. like I do

          I know what you mean, I program web apps in a varity of languages which does give a very clear insight to the problem. I have no interest in rooting my device because the security loop holes in purchases from google play. I seriously do not recommend you root devices that transact payments. Plus I have every faith in K that it will get resolved promptly. Thanks for the advice though, but patience is a virtual.

          My problem is that I can’t even connect to dropbox to download, upload, or open files. When you press the button to link the game to dropbox, it leaves the game to open the browser. This causes SC to restart, and it’s no longer prepared to accept the permission. It makes you start over, and that’s where the problem lies. It’s kinda like on Windows Phone how some apps (still) aren’t optimised to continue running when you leave them and restart when you come back to them.

          My device is rooted because obviously the Touchpad wasn’t meant to run Android, so I’ll look around for the files to see if I can do a direct copy/transfer.

      The worlds are saved in data/data so backing up Survivalcraft with Titanium should be sufficient. Then upload the backup to DB. Not the answer you were looking for but a solution.

    And just thank you, i already have many ways of using this new tool. As i said a few pages back it could also affect water flow and maybe many ideas ive not even thought about.

    And with affecting water we could also allow the water being affected to cover copper wirring that becomes disabled. You stated cables may not be placed under water and this will open up many many usable circuits. the simple upside down trap door opens up so many avenues. Can’t wait.

      adventure creators will get so much from alowing the trapdoors to work the way normal doors work. given the way some items work both ways, looking at other blocks these may also offer a second use, i will say no more, but there are some simple implementations that open up 100’s of uses. this game becomes limitless when looking at it from another side. Keep your good ideas coming. just to say you need to change things just a little to require huge additions.

    When I lost my world it was because I accidently hit the home button then when I try to go back to the game it hangs on a black screen which I then have to force close it. When I reload the game my world is lusted but has no name (title) and will not open.

    yah my scworld slurothan 3.0 got deleted but luckily I had it backed up on dropbox. I lost one of my quests completely. Was frustrated but I remade it and 2x better the second time. Thank you for addressing this deleting problem, I love survival craft so keep up the good work. lol

    Cant wait for the new update. I’m going to hold back making quests until I get the update- which I’m willing to wait for because I have tons of patience unlike most people. That and I can still create the world with doors that lead to empty quests.

      Trying to back my world up results in the black screen because it requires the game to be run in the background. So I can’t even back it up. Spent about 2 weeks on one of the worlds and lost it. Then about a week on another so have given up on the game untill it has been fixed. Nothing to do with low resources from my tablet since it has 2GB RAM, Quad core. Shame really. But once the problem has been fixed I will go back to the game. In the meanwhile I can only wait :(

        I’m pretty sure your world got completely lost. if you press edit on the blank name world the world wont even state what version it is. I know this because my world was erased completely and am good with software. I tried to embed my erased world into someone elses to trick the system which worked and the map was their but my created stuff was none existent luckily I backed up my world to dropbox at least 20 times and only lost one quest. I luckily started doing this because I in the paste have destroyed an entire city building a floating city above my main city. Of which had lava traps – and one of the traps leaked out lava all over the bottom one. This destroyed almost everything before I noticed anything happened. So I learned my lesson. Even though bad stuff happens like this I still play this game. Barely even play my ps3 anymore because I’m on my phone playing survival craft.

    Can you make chain reactions

    • brian t
      Posted December 11, 2012 at 00:02 | Permalink | Reply

      Kaalus has been very busy so i guess he pobably is in the middle of the chain reaction. But if the upside down trap door enables us to affect water flow which it will, we be able it to alter circuits thus leading to the ability to create the said chain reaction. I think we should be careful though, too many chain reaction may make the game pause a little. But only the Big guy could comfirm that.

    Maybe as an addition you could add… sideways trapdoors? And possibly put a ‘lock’ electric piece? You know, to lock doors with? So you cannot just open the door by tapping it. And to unlock it, deactivate the circuit? More food…

    I’m playing SC on my Kindle Fire. It’s awesome! But I just lost my world, too. I am absolutely not technically savy and I followed the instructions on the drop box tab, but I can’t make heads or tails of it. how do I save to the dropbox? I’m not sure if I can save while I’m in the game.
