Alpha 1.21.7

On certain Android devices the game takes extremely long time to load. Some people reported times of up to 10 minutes, which is just mad.

After collecting a number of such reports I finally pinpointed with some confidence one cheap device that reliably exhibits this problem: a Cyclone Voyager 7″.


It must be said, it’s another cheap Chinese Android tablet, and I don’t recommend buying it. The worst part is the screen – viewing angles are so bad that even when looking straight on, one side of the screen is pink and the other green. It will kill your eyes. And it’s just 800 x 480, which is rather mediocre even on a 4 inch phone these days. Amazingly, it’s pretty fast – I don’t see much performance difference between this thing and Nexus 7, which costs twice as much. But that does not make the screen look any better.

Most importantly, it took good 3 minutes to boot the game! If you’re a dev, that makes you happy :-) Having a reproducible case is always the best.

Some time later I had it figured out. It’s the compilation of the shaders. Survivalcraft 1.21 needlessly compiles a large number of shader variants at startup, even though only a few are used. This is usually not a problem, because it takes just milliseconds on almost all devices (that’s why I haven’t noticed it). But some evil ones, like this Voyager, take a few orders of magnitude longer.

So I put in a fix, and the game now compiles the shaders lazily, only when they are actually needed.

I am now testing the fixed version, which is 1.21.7. I plan to put it on Google Play soon. If you have been experiencing long load times (or just black screen at startup if you’re impatient), please give it a try. One popular device that I suspect also has this problem is Samsung S3 Mini.

Note: this bugfix release will have none of the 1.22 features – 1.22 will arrive when it’s ready (farming is still in progress).

I will let you know when 1.21.7 is out.

    This is why you are a legend, you bother to test out your game on different devices and tell us what you have found. I have an HTC one x and have no trouble at all. Looking forward to the next non bugfix update.

      No problem. Hope you didn’t take offence when I bashed your device in the post.

        Hey, Kaalus, in 1.21.7 are you adding more hearts? Becasue in the screen shot up there it has six heart, when my Survivalcraft on iOS has only four hearts.

    I admire your attention to problems and not just to complaints about difficulties it helps to better the game and to keep it realistic like. So if there’s a problem as I have yet to see you seem to get right on top of fixing it without a moments hesitation I respect that and hope that it is worth your time.

    Thanks kaalus. Also,I have a little problem. Ever since I got 1.21,it says I can only have a maximum of 20 worlds. I have about 70 worlds. But,sometimes,I can still download worlds! Also,I think u should put a button on the screen where u select worlds that allows u to delete multiple worlds at once,because it takes me like,5 minutes to delete 3 worlds. This way,with the tool,it’ll be faster to delete worlds. But,as I said in the beginning,it randomly allows me to download worlds,I think this is kinda odd. Do u know why it says I can only have 20 worlds?

    Minecraft PE will get servers tomorow it will definitely get more players. Right now it has more players than SC. Online multiplayer for SC will take a long time to make so stop hoping. Just face it MCPE is the best. Yes, SC has more stuff but its online multiplayer that gives MCPE the huge advantage. Unless SC gets online multiplayer it will always be behind MCPE.

      I’m afraid I have to agree with you there. Playing Multi-Player just makes MCPE so much better than SC.

        You both are wrong, Mcpe just sucks, online multiplayer will change nothing. You have to buy a expensive game wich have nothing to do and after you have to pay for a crap server, to do nothing e.e, why pay for that… We have World of Cubes hahaha. And many players from minecraft just bought it thinking it was like PC version. Now they are angry, cause they see mojang spending 6 months working on an update that add nothing useful, this happen in 0.6.0 too. 4 months to add only the armor and clouds. If you go to comments you can see people saying, “buy the game called survivalcraft, it’s just like the pc version”.

    Thats why Mcpe is 2nd paid on the app store and SC is 6th (as of now)

    Also SC only has a rating of 4/5 stars MCPE has 4.5/5 stars

      Indeed, the start-up game being developed by one man as a hobby project when he is out of his day job, which started out in the little known platform known as Windows Phone, has equaled the venerable multiplatform franchise with its large development team known as Minecraft. Thank you for reminding us how great Survivalcraft is. Now go back to eating your virtual MCPE cake.

    Loading is fine on the Kindle Fire HD. Though I’ve noticed that for a while now the black screen that appears when I open the app is there longer. Not much longer, but long enough to be a little bit annoying.

    P.S.Kaalus you are awesome! I absolutely love the game! Can’t wait for the update!

    You guys should really put some type of mechanical car in Survivalcraft. It takes a while to move around on foot and on animals.A car that we can either build or use would really help us get around. Please, Please, Please!!!!!!!!!!!!
