Beta 0.29


Released on May 20, 2016

  • INFO: Well, it turns out there were gigantic gamebreaking bugs. Hopefully this is the last one for 1.7.10, but I am not going to promise that because, hey, look at what happened with 0.29.2! \o/
  • FIX: Fix crash when putting armor pieces (like the Traveler's gear) in the Tinkers' Construct Tool Forge (#439).


Released on May 3, 2016.

  • INFO: Assuming there are no gigantic gamebreaking bugs (like every item being given NBT tags when broken *cough cough*), this is the final 1.7.10 version. After this, we will begin working on the update to 1.9.
  • NEW: Native MineTweaker integration. You can now add/remove carving table molds, crucible liquids and recipes, rock smasher recipes, and steaming recipes. Please keep in mind that some things may not work as you hope when using /mt reload. Some things cannot change mid-game for FSP, so when modifying the script, if using reload did not work, be sure to restart the game (#386).
  • TWEAK: Forest Fire improvements: Does not consume additional steam on use, can burn blocks that aren't logs, and burns blocks in Y levels above and below the starting position (#412).
  • TWEAK: Leaf Blower improvements: Destroys leaves in 9x9 area instead of 3x3, and better checks to allow non-OreDict leaves and other materials to be blown (#411).
  • TWEAK: Dragon Roar is now equipped in the mask slot (#409).
  • TWEAK: Rebreather is now equipped in the mask slot (#404).
  • TWEAK: New "single button trackpad" config option to resolve issues with single-button trackpad users (like those who use a Macbook with no mouse, like me) not being able to use the ctrl-click feature with the Esteemed Innovation journal. This will make the ctrl-click feature not care which mouse button is down, as long as one of them is, as LWJGL seems to register all single-button trackpad clicks as only a single mouse button, rather than 0 and 1 respectively (L and R).
  • TWEAK: Indicate that The Void requires the tool be wound up in the book, as it was not obvious before (#395).
  • TWEAK: Improve area of effect mining speed a bit, so it is actually worth using over your fist.
  • TWEAK: The Void upgrade now displays your inventory's coordinates when in a tool. If no inventory is set, it will simply say "The Void" (#407).
  • FIX: Precise Cutting Head priority is lower, which resolves ore duping issues.
  • FIX: More permissive can-harvest-block code for the Precise Cutting Head, which resolves issues where blocks that have no specific harvesting tool or a really low harvest level (like Glowstone) were not getting silk touched (#410).
  • FIX: Fix Redstone Ore not dropping Redstone Ore. The fix for this is moderately hacky, since Redstone Ore and Lit Redstone Ore (which is the block broken) are different blocks, but there should be no side effects.
  • FIX: Improve entry finding code for ctrl/sneak clicking stuff with the Esteemed Innovation journal. This resolves the issue where these features will take you to the middle/end of an entry (for the crafting recipe) or the first page in an entry with many different subentries like the upgrade pages. For example: Steam Hammer would take you to its crafting recipe, and Timber Chain would take you to Forest Fire. These issues never existed at the same time, but there was always at least one of them present. Now, neither.
  • FIX: Items dropped by things that modify block drops, like the Multiplicative Resonator, were not effected by the Void. Now they are.
  • FIX: The Void not sending items anywhere if the inventory was full. Now the items are dropped like normal (#407).
  • FIX: Resolve many NullPointerExceptions caused by connecting/disconnecting steam transporters with the Pipe Wrench (#405).
  • FIX: Set damage to 0 (0 SU) instead of 1 (800 SU) when it is going to get all of its steam drained.
  • FIX: Fix reversed divison in addSteam resulting in bad values thanks to int divison.
  • FIX: Battle Drill properly requires the player to be sneaking.
  • FIX: Fix Exo Projector for steaming recipes with old metadata style (-1 -> 0).
  • FIX: setHarvestLevel is called in BlockSteamcraftOre. This should fix various strange issues, most notably fixes the Exothermic Projector not smelting our ores (zinc and copper).
  • FIX: Fix steam tools ever losing steam such that they would break (#399).
  • FIX: Steam Saw can efficiently break leaves (#396).
  • FIX: Drain the proper amount of steam from the Exosuit when the tools have run out of steam, and they get revved (#400).
  • FIX: Fix NullPointerException when using fake players with the steam tools, like the tablet from Thaumic Tinkerer or Thermal Expansion's Autonomous Activator (#385). This also prevents crashes from mining non-standard (instantly broken, like tall grass) blocks (#392).
  • FIX: Fix Air Strike Conversion Kit only working when the player is not rocket jumping (#387)
  • FIX: Use EntityLivingBase#ticksExisted instead of our own integer to check when to remove the good and bad Exosuit boosts. We try only once per second instead of 5 times per second to remove them now. This inadvertently resolves an issue where the bad boost was not removed if the last piece of armor removed was not the chest plate (#413).
  • FIX: Non-steam tool items no longer get the Ticks and Speed NBT tags set to them. This solves an issue with item stacking (#389)
  • FIX: Flash Boiler filling bug preventing the user from filling outside of the GUI (screw, right clicking with a water container, etc) (#390)
  • FIX: Leap Actuator entry is in the right category in the book, Foot Slot rather than Heel Slot (#391).
  • FIX: Fix NullPointerException when mining the inventory set to the void upgrade, or when that TileEntity has been mined. When this occurs, the void inventory will automatically be unset (#394).
  • FIX: @VERSION@ in mcmod.info properly gets replaced by the version number in the build script.
  • API: ISteamToolUpgrade#getInformation now gives you two ItemStacks, one for the upgrade, and one for the containing tool.
  • API: ISteamTool now extends ISteamChargable.
  • DEV: New -Pdev option to create a dev build, with version numbers as RELVERSION-LATESTCOMMIT-dev.


Released on April 24, 2016.

  • FIX: Shovel and Saw no longer have experimental sound code that I apparently forgot to delete.
  • FIX: Don't modify tool NBT while mining. This resolves a bug preventing the tools from mining at all
  • FIX: Handle client chat messages only on the client, not the server. This fixes the NoClassDefFoundError when installed on a server.
  • FIX: Properly check harvest levels (greater than -> greater than or equal to) for steam drill heads.
  • FIX: Fix potential issues with client-side classes in the Hydro/Pyrophobic Coatings code.
  • FIX: Actually include the Rock Smasher's NEI GUI.


Released on April 23, 2016.

  • INFO: Welcome Lance5057 (of Tinkers' Defense) and DoopPatrol to the Aesthetics Team! Also welcome DivineAspect to the Testing Monkeys team. Divine also helps out a lot with game design, and Lance helps out a lot with development and game design. These new team members have been crucial to this release, and many more to come! <3
  • NEW: Steam Tools can now be upgraded in the Engineering Table. Each tool has a head slot, and a core slot. Some upgrades can be placed into the core slot of any tool!
  • NEW: Exosuit steam will now automatically power the steam tools if they run out.
  • NEW: Steam Cells. Empty Steam Cells can be charged in the Steam Filler to produce Full Steam Cells, which can be used to charge the Exosuit and the Steam Tools with a right click, or automatically with the Steam Cell Filler bauble.

  • NEW: Gilded Iron Exosuit Plate
  • NEW: Gilded Iron Plates, made from dunking iron plates in gold
  • INFO: Release files now use the naming convention "FSP-MCVERSION-RELVERSION"
  • NEW: Tinkers' Construct integration with a new Steam Modifier for tools, which repairs them using steam. TiCo tools with this modifier can be charged in the Steam Charger (Issue #307, PR #369) (Lance5057).
  • NEW: NEI support for Rock Smasher and Steam Heater recipes (#328, #243).
  • NEW: Non-vanilla water containers can now fill boilers (#245, PR #339) (Vidar Johansen, vidaj)
  • NEW: Steamed Salmon (#141).
  • TWEAK: Gilded Iron Ingots are now registered in the OreDictionary as ingotGildedIron
  • TWEAK: Entries opened through shift or control clicking now open to their first page, rather than the page that contains their recipe (#377).
  • TWEAK: SU amount now only shows up in the Exosuit's tooltip if it actually has a tank installed.
  • TWEAK: Valve Pipe redstone control is enabled by default now.
  • TWEAK: The Valve Pipe's redstone control is much more consistent now. When the signal is applied, it closes the pipe, and when it turns off, it opens the pipe. This change does not sacrifice the existing manual system (#263).
  • REFIX: Server crash caused by shift-right clicking things with the Esteemed Innovation journal (#168 #347 #362).
  • FIX: Improve tool tick/speed saving. These values are no longer saved with the player, but with each individual tool. This fixes rendering weirdness when there are multiple tools on the screen. Unfortunately, this also brings a new issue that will not be fixed until post-1.7.10, where the reequip animation plays a few times when winding up the tools.
  • FIX: Pages in the Esteemed Innovation journal no longer overlay on top of each other when the book is opened through in-world shift clicking or in-inventory control clicking (#287).
  • FIX: Exosuit Chestpiece properly loses its charge when its tank is removed (#185).
  • FIX: Exosuit Chestpiece (and really any other thing that had this issue) no longer spins around when charging on the Steam Charger with ItemPhysic installed (#357).
  • FIX: The Rock Smasher API is actually used now.
  • FIX: Vacuums, Fans, and Steam Hammers render on the right side of Item Frames now (#163, #51)
  • FIX: Improve performance of Steam Exosuit, Survivalist's Toolkit, and Steam Tool events (#354).
  • FIX: Improve performance by dynamically setting needed villager fields accessible only once, instead of every tick.
  • FIX: Improve performance by not using unneeded Java reflection in the following areas: pre-initialization, Extendo Fist range extending/checking, Steam Whistle sound playing/checking, villager updates, Blood Magic integration, Botania integration (#353).
  • FIX: Piton Deployer uses the use keybind rather than the right mouse button (PR #350).
  • FIX: Greatly improve networking/packet code. We now use the SimpleImpl system rather than an ancient packet sending/handling system. There are 5 fewer packets being sent, so you should see a huge improvement in the client/server bandwidth usage. This also included fixes for potential, but never noticed/reported, bugs involving modifying NBT data on the client instead of the server. The five packets that were removed were the SpacePacket (sent to server every tick that the player was using the jump key), NoSpacePacket (sent to server every tick that the player was not using the jump key), RocketJumpHackyPacket (sent to client every time the player used the rocket launcher and a rocket exploded), ExplodePacket (sent to client never), and GrapplePacket (sent to server every time the player used the Piton Deployer) (#344, #183, PR #350).
  • FIX: Replace all references of getEntityId or getEntityById with an IExtendedEntityProperties class (one for players, one for villagers). This should improve performance, predictability and reliability of the code (PR #343, and inadvertently PR #350).
  • FIX: Slightly improved performance of some API stuff. You might see performance boosts when loading the game, or viewing the book.
  • FIX: ClassCastException error spam that typically occurred on Cauldron servers during networking (#173).
  • FIX: Monocle keybind is now translatable (PR #342)
  • FIX: Fixed the Exosuit rendering bug in which the arms would stay in place as if they were constantly aiming a bow, typically occurring after using a Flintlock Weapon, although that is not necessarily relevant to the bug aside from testing (#305).
  • FIX: Rocket Launchers can now shoot through the correct blocks, like tall grass (#338).
  • FIX: Fixed all Steamed Food APIs and what-not, allowing for metadata items to be output as steamed food easily (#141).
  • REMOVE: Config options to toggle blocks without effect ore generation no longer exist, because they caused too many problems for no gain. What I mean by this, is that the existence of the ores is not dependent on the generation of them, thus this config just overly complicated the ore code. This lazily fixes a crash bug, too. (#330, #358, #381)
  • FIX: Better integration code by actually using the variables that were added in the cross mod refactor.
  • FIX: Flash Boiler now properly updates the heat countdown (#272).
  • FIX: Boiler heat countdown no longer stays at 0 (#272).
  • FIX: Boiler heat countdown no longer resets when the GUI is exited (#272).
  • FIX: Fix crash that occurred when looking at the ore page in Esteemed Innovation (#321) (jaredlll08).
  • FIX: Fix Vacuum ticking block entity crash (#191) (jaredlll08).
  • FIX: Steam Heaters from Steam Workshops are no longer orphaned/duplicated (#294).
  • API: New addSteam method in ISteamChargable to add an amount of steam to the item. This should expect negative values used to remove steam.
  • API: New constructor in BookPageItem for string formatting.
  • API: New ISteamTool interface. It contains an isWound(ItemStack), hasUpgrade(ItemStack, Item), and toolClass() methods.
  • API: New ISteamToolUpgrade interface. It contains a renderPriority(), getToolSlot(), getInformation(), getIIcons(), and isUniversal() methods.
  • API: New SteamToolSlot enum containing all of the valid steam tool slots (Note: tool integer -1, used by TOOL_CORE, is valid for all tools).
  • API: New UtilSteamTool method to assist in working with steam tools. It contains hasUpgrade(ItemStack, Item), getUpgrades(ItemStack), getUpgradeStacks(ItemStack), and getHarvestLevelModifier(ItemStack).
  • API: New AnimalTradeEvent, fired when a player trades with an animal using the Frequency Shifter
  • API: Proper method in UtilPlates to remove a plate from an Exosuit piece
  • API: ExosuitSlot enum now uses CONSTANT_CASE, so please update your upgrade code.
  • API: Clean up a lot of methods and add docs to a lot of things to help out other developers. You will probably need to update your code to use the new stuff, but chances are, the things that were removed were not even used by you.
  • API: Remove IEnhancement#cost and IEnhancement#getEnhancementName and document the IEnhancement interface (#356).
  • API: Renamed a lot of things in the SteamcraftRegistry, and added a bunch of new methods for adding/removing things (#327).
  • API: You can now actually add molds without having to implement ICrucibleMold. The SteamcraftRegistry molds field didn't really do much because you were required to implement ICrucibleMold in your item. Blank molds are now considered molds instead of standard items.
  • API: addCarvableMold takes an Item instead of an ICrucibleMold.
  • API: New removeMold method to remove an item from the list of valid molds.
  • API: Rocket Launcher shots now post an ArrowLooseEvent to the Minecraft Forge Event Bus, like the Firearm shots.
  • DEV: We now use Travis CI for build testing.

This doesn't change anything in-game or from a user POV, but for people working on the mod, and for people wanting to learn from it, this is very helpful. This includes p_######_#_, some wrongly named variables (tileentitysteamcharger set to TileEntitySteamHammer), and some more descriptive variables (World var1, int var2 -> World world, int meta in createTileEntity methods).

  • FIX: Got rid of commented out WAILA integration, because WAILA Integration mod has support for FSP.
  • FIX: Got rid of derpy code I wrote when doing some rendering stuff with the Steam Filler; it now uses the old code that Flax (or someone) wrote ages ago. This should fix some rendering issues.
  • FIX: Capitalization in config file.
  • FIX: Monacle -> Monocle in config file and key bind screen.
