Disappearing Coal Blocks

As most of you know, coal blocks are supposed to burn forever. And so they do, unless the burning material happens to sit at a chunk boundary… The fire algorithm can in rare circumstances extinguish such a fire, taking the burning block away with it.

Big thanks to Spooner for sending me a reproducible test case.

I have investigated the issue and I have to sadly report that I currently see no easy way of fixing it! The proper way is to introduce another block type for forever burning fire, but this solution is totally out of proportion with the problem we I am trying to solve. There is a trivial workaround to avoid your fire blocks disappearing: move them away from chunk boundary (chunks are 16×16 blocks large).
Fireblock

This coal block sits at the (invisible) chunk boundary, and so may disappear if you move away

The fix will be trivial once we migrate to 32 bit blocks. I will just reserve one bit to say that the fire should never get extinguished. As it stands now, all bits are used for fire data, so there’s no space to save that information.

I will give it some more thought. There are hacky solutions, but they are nasty and there is a risk of introducing more issues. Maybe I’ll find something better. For now, just move your fireplaces and balloons!

    Kaalus, I appreciate you working to iron out major issues and the bugs rather than slamming new things in (ie. Multiplayer) and generating new gateways for more bugs. But for those who want multiplayer, read this would you?

    What /are/ the benefits?

    It would take Kaalus much data space and time to create the servers, implement the data, and at the end, he might even cause the game to be plugged up by the coding for multiplayer just for your “simple” requests. Don’t spam him with adding multiplayer, minecarts, (minecraft things), etc. Respect that he is working hard with his free time in his own life, not yours. We all have lives, and I am sure you would not like to be barked orders at. Kaalus tries to make SC a great game by ironing out the bugs and issues so you can build your best. You are lucky to even have your Community Content.

          Were I live it is a free country so I won’t stop anyone. But it is rather annoying sometimes so please remember this. Also kaalus doesn’t want to add multi at the moment because he wants to make and fix things first

    I have never ran into this problem yet. Guess I just got lucky. One thing with the coal blocks I have noticed is that using them in a furnace can be wasteful. It will smelt or cook an entire stack and if you keep the stack renewed and keep pulling out the finished product (keeping the furnace going without stopping) it will go a really long time., But it also will use up the block (which is made of 9 coal chunks) if you only put in say one item. In other words, just placing an item in the furnace automatically uses 1 fuel (weather it is a chunk or a entire block) no matter the size of the item stack. Don’t know if it’s possible but It would be nice if coal blocks would last for a certain number of uses.

        I have been thinking of adding an enemy castle, I just have to get the motivation to get myself to start. I am just worried though because if I add another castle, the world will lag a lot more than it already does (lag when building) I will start thinking of a different design for a castle and then I will build it. it will probably be around update 6.0, but good idea.

    Kaalus – What are the added benefits of going to 32 but blocks? Aside from them being more configurable, any examples or ideas of what you can or want to implement in the future? My first post =)

    • Posted September 17, 2013 at 13:47 | Permalink | Reply

      Lots of existing blocks would benefit. For example, we could have painted stairs, slabs, fences. Electric blocks could be placed on horizontal surfaces. Wires could coexist with electric devices in the same block. Torches that automatically go out after some time. No more 256 block types limit. No more 4 bits of data per block limit.
