World Generation and Spawn

Classic average temperature vs TNG average temperatures

z=0 is now in the temperate zone, and spawn selection is vanilla Minecraft, so the range of temperature at spawn is smaller.
By default, the temperature gets warmer in the positive-z (south) direction for 20 k blocks, and then gets colder again, and the reverse for negative-z.

Classic worlds had spawn at z between -5 k to -15 k, had max temp at z=0 that fell off to constant cold temperatures at roughly z=±25 k blocks and further.

Temperature can also be affected regionally, by up to ±3 C. This means moving east / west can see temperature changes, although not as drastic as moving north / south.
Moving east / west will also see changes in total rainfall in a cyclical nature.

Nugget Generation

Surface nuggets are created from ore bodies at y-level 82 (half way through the usual second layer) and above, and within the 3x3 chunks around the chunk where the nugget spawned.Needs confirmation - this is currently in development / testing phase.

Clay

Clay dirt (blocks found in natural clay deposits) are now affected by gravity.

Various plants that indicate a clay deposit

Indications of clay deposits

Seven different plants now show where clay is:

Athyrium Fern
Canna Lily
Goldenrod
Pampas Grass
Russian Sage
Rose
Water Canna
Yucca

These images are 2D sprites, and will look different in-game. Most plants will also go through seasonal changes - flowering in spring, blooming in summer, then dying down in fall and winter. This means that searching for specific flowers may not always work, as the flower may only be visible during specific months.

Plants/Trees

Many more flowers and plants appear different through the seasons. Tree leaves do not change colors according to the season.

Many tree models are updated, and may be different sizes than before (e.g. White Cedar). Tree species vary by rainfall and temperature. See this Desmos graph and this Google spreadsheet for details.

Mobs

Mob AI is still vanilla for deer, etc.

In-world Creations

Pit Kilns

Place items in pit kilns or in world with "v" by default instead of shift-right-click. "V" will place an item flat like rocks/nuggets.

Firepits

To make a firepit, use 3 sticks, at least one log, and optionally 1-5 pieces of tinder (straw, paper, etc.). Tinder will increase the chance of success 10% per piece. To light, use the usual firestarter.

Forge

Side slots cannot hold charcoal or ingots.
Side slots only hold one item each, and only those which can hold liquid and heat (currently only molds and small vessels).
Tool molds placed in the side slots will be filled if Tier I-II tool metals melt in the forge.
Small vessels will catch melted liquids from the forge, up to 4000 units.
Small vessels in each of the four side slots can catch different metals.
Small vessels can be heated in the forge, and will alloy their contents at Brilliant White temperature.
Anything that can normally be fired in a pit kiln can be fired in a forge, by letting it heat up to Brilliant White temperature.
Metal armor and weapons can be melted in the forge.
Food can be cooked in the forge, although it will burn if left unattended.

Anvils

Welding still needs flux in the anvil, but otherwise happens outside of the GUI. Right click on anvil will put item in slots. To weld, right click on the anvil with a hammer in hand if flux and ingots are ready.
Anvil GUI has been updated.
Worked ingots will have their plan reselected when they are placed back into the anvil.

Chiseling

In-world chiseling of bits is gone. Other mods do this better, and we do not feel it necessary to re-implement.
Smooth blocks are craftable with a chisel.

Lumber

Lumber is still the output from Log+Saw recipe, but cannot be placed in the world. Like chiseling, use a different mod if this effect is desired.

Sluices

Can be put down into any level of flowing water. They scan a 1 chunk radius for ores, consume 1/20 of a block of sand or gravel every 5 seconds, and have a 5% chance of producing a nugget for every operation. The gems and ore nuggets float out into the water block below the sluice. There is no GUI. You cannot fill a sluice with a Gold Pan.

Player

Skills

Prospecting skill increases only when the propick is clicked on ore blocks at least 192 blocks apart.
The three smithing skills have been merged into one "Smithing" skill - however there are still different categories internally, so you do have to smith different types of objects to attain full skill.

Food

Taste system is gone and won't be returning.
Pickling, vinegar storage, and vessels work for preservation.
Food weights are gone. Each piece of food roughly translates to 5oz of food(?). This is an important compatibility change.
Decay works very differently. Every piece of food has creation and rotted by dates. These can be extended by preservation, and may prevent food from stacking. Combining food in the crafting grid meshes the decay dates, so foods can stack. Not yet balanced

Items

Rope is not craftable, vanilla leads are an acceptable replacement. Potential recipe with jute fibers to vanilla lead

Containers

Barrels only contain fluids. They are still used for pickling, tanning, etc., but do not have a multiple-slot inventory.
Both small and large vessels preserve food. (Other containers?)
See Forge section for additional uses of small vessels.
The back slot for barrels, anvils, large vessels, or quivers is gone. More than one anvil, sealed barrel or vessel in your inventory will result in extreme slowness and fatigue. Even one item will greatly increase your water and food usage. not yet balanced

Ceramics

Empty ceramics hold heat even after the metal is removed, and will cool down at the usual rate.
Hold down right click at a water source block with a filled Gold Pan to pan for platinum, silver, gold, or copper nuggets.

Porting Project

Since this project is still underway, there are several things which are not yet implemented. The current project todo list is located on github.

Sulfur doesn't generate yet.
In-world chiseling of smooth stone is missing. May be implemented?
Sandwiches and Salads are missing. Some form of food preparation/cooking is on the todo list.
Salting, brining, smoking, and drying are not implemented (yet?).
Gunpowder barrels are still in question.
