So here’s a 3.1.3 release of BuildCraft, for bugfixed, some of which being really annoying:

#166 fix wooden/iron pipes input/output slots
Wooden and iron state state was not computed correctly and forgot upon reload, now fixed.

#172 fix NPE in assembly tables
Fixed a null pointer exception when openning an assembly table.

#173 fix builder stopping before end of work
When connected to a path, the builder was sometimes stopping work too early. Now fixed.

#174 enchantements losts in pipes
Enchantements are not lost anymore when transporting items in pipes.

#175 fix laser spawning
Fixed major performance issue in laser spawning.

#176 gate performances problems with signal and redstone
Fixed major performances issues with pipe gates.

#178 iron engines doesn’t support non-bucket items
Iron engine doesn’t replace all inputs by empty buckets anymore.

#177 fix glowstone in blueprints
Glowtone blocks are now required instead of glowstone dust in blueprints.

So here we go, support for Minecraft 1.1.0. Thanks to the amazing work of the community, for ModLoader, ModLoaderMP and Minecraft Forge, this is probably the fastest it ever happened! And good news for you guys, there’s a lot of very nice enhancements for 3.1.2. First of all, some major optimization so your BC worlds will run a heck of a lot faster. Even faster than with the 2.2 branch! Included in these optimizations are various rules with pipes containing too many stacks (thanks Player!) which will either group items if possible, or explode if really too crowded.

Other than that, blueprints go one step further into natively supporting third party mods. They should me much more clever at identifying what items are required to build a given block. For advanced blueprint support, dedicated modder work is still required. The interfaces have been greatly enhanced in response to community request to handle even more cases, in particular the ability to use items as opposed to consuming them.

Work has started around the filler. They can now plant seeds, are fully supported in the blueprints, and offer a “loop” action through the gates which will allow them to carry on working when done.

Other than that, various bug fixes and minor enhancements. Note that the 3.1.x API is now frozen – so if you’re modding, you can start to rely on it. I’m now switching gears, and will start to move 3.x out of the alpha program to make it into beta. This means SMP implementation and documentation. Note that 2.2.x is still the mainstream version at the moment.

BuildCraft 2.2.12 changes

#158 fix pipe NPE in builders

#160 pipe should explode when containing more than X elements

So here we go already, a new BuildCraft released named 3.1.1. Fixes a couple of bugs, but more importantly, the blueprint format has been reviewed. For those who now what that is, save / load is now based on the usual NBT minecraft classes. What this means for you players is that the bpt files that you have been started to work on needs to be regenerated. If you lost the world from where they were generated, you can install BuildCraft 3.1.0 from here, then deploy the structures, install BuildCraft 3.1.1 and finally generate the updated blueprints. Sorry for the incovenience – but it’s really really worth the trouble. Note that my blueprints pack has been updated with this new format, now version 1.1.

The other benefit of this new implementation is that it will be able to support much more mod blocks natively. Advanced blocks still require an additional level of integration, but the way blocks are saved in the world is now used by default to save blocks in blueprints, making things potentially way better. Hopefully, this will be the last format change.

In any case, here’s the complete changelog:

#127 add recipe for path mark
Path marks can now be crafted with a redstone torch and a cactus dye.

#129 added protection for null engines
Null pointer exceptions for engines have been fixed.

#130 errors in API
Fixed error in API dependencies.

#132 fix stripe pipes
Fixed a number of issue with stripe pipes, including the fact that they would drop an extra pipe and that they would not be able to use bonemeal.

#133 wheat doesn’t drop seeds on stripe pipes
Crops now drop seeds and wheat.

#134 move blueprint format to using NBT components
Major change of the blueprint format and interface, see above for more details.

Dear all,

I’m very pleased to announce the release of BuildCraft 3.1.0 – the first release implementing blueprints and thus completing the initial mission of BuildCraft! Check out the tutorial video:

Needless to say, this is very beta. However, a lot of effort has been put into providing a flexible blueprint format and API – so that part should converge pretty soon. If you would like to enable blueprint capabilities to your mod and what I provide is not enough, let me know!

Anyway, here’s the changelog:

#10 blueprint library
Blueprints and templates can now be stored in a library.

#17 implement an animation for building / removing block
A robot animation has been implemented for blocks adding and removing blocks

#75 create a new “silicon” mod
Silicon-related objects (laser and assembly tables, crafting pipe wire and gates) have been moved to a separate part of the mod, making logic gates clearly optional.

#81 fix liquid returning to refinery
Recipes for refineries can now be specified through an interface, preventing to get anything else.

#86 create a structure pipe
A structure pipe has been added, holding wire and gates, and having the ability to connect wires to any kind of pipe.

#95 fix potential null pointers exceptions in liquid containers
Null pointer exceptions have been fixed in liquid containers.

#96 trigger API interface
An API is now available to develop custom triggers.

#97 stone engine is missing the has-space-for-item-Trigger
Fixed stone engine not having “has-space-for-item” trigger.

#99 implement ability to repeat a pattern with the builder
A new type of marker, path marker, has now the ability to devine a patch on which a builder will repeat a pattern.

#103 add API for refinery recipes
Refineries recipes can now be specified from the BuildCraft API.

#105 create real blueprint
Real blueprints are now available, providing means to record completely a construction.

#106 pipes ignore getInventoryStackLimit
Adding objects from pipes to inventories now takes into account the getInventoryStackLimit property of inventories.

#109 remove hard-coded height limits
Height limits have been removed when placing pipes.

#123 get rid of Utils.getWorld
Utils.getWorld is not used anymore, hopefully simplifying mods such as Zepplin, and eventually allowing SMP nether with BuildCraft.

#124 add a pipe placing an object
A new pipe has been added, placing an object in front of it.

#125 add ability to give other than empty bucket in tanks
Tanks will now return any container when empting an object.

Here comes a minor BuildCraft release, 2.2.11. You shouldn’t have to upgrade except if you are having troubles with server, in particular for migration between your 1.8.1 worlds and your 1.0.0 ones, where a major issue has been fixed. Here’s the changelog:

#25 items can’t be thrown out of obsidian pipes
Items can be thrown out of obsidian pipes again.

#114 bucket “eaten” by stone engine
Stone engine do not remove the bucket anymore.

#116 temporary fix for the refinery

#118 issues with auto-workbench refresh
Fixed a dupe bug (again) in SMP auto-workbench

#119 consider move FillerPattern and FillerRegistry out of the API
Temporary moved FillerPattern and FillerRegistry out of the API since they rely on core. AFAIK, nobody is using these at the moment, but let me know if that causes a problem.

#121 fix potential pipe exception in SMP
Fixed various exceptions in SMP when loading worlds with invalid pipe contents.

The BuildCraft server (s15972928.onlinehome-server.info) is to be updated soon. Enjoy!
