My attempt at a Stainless Steel factory. It is very slow since it has to wait for them to cool of.

Suggestions for more Vehicles.

Elevator. Goes up / down. Needs at least one voxel on one of it's side all the time. So it cant travel into space.

Car. Can only travel on flat ground. Maybe 2-3 times faster then walking.

Boat. Can only travel on water.

Train. Who doesn't like trains. Needs rail to travel on.

A lot of robots and machines uses a Wireless Energy Transmitter/Receiver to power them. But there is nothing in the game that actually generates this power that they are to receive.

So I suggest 4 types of power generators.

Solar panels. (I don't know if this works on this planet since it looks pretty dark.)
Coal Power Plant. (Not that environment friendly.)
Water Power Plant. (Needs a flow of water to drive a turbine to generate the power.)
Atomic Power Plant. (Since we already have Uranium.)

The sequencer is probably the most powerful item in the game as it is now. Here are a couple of suggestions to make it a bit less power full to make the need for the other items (belt conveyer, voxel materializer/dematerialize, atomic compressors) higher.

Limit the "Input" field so you can only pick up stuff from it, not be able to put in stuff directly there. This way you will need to use Atomic Compressors, Voxel Materializers and conveyer belts to feed the Sequencer.

Make the "Sequence" field not store actual voxels. This is to prevent it from being used as a high capacity storage device. Explanation: If you drop 1 Coal in to one "sequence" slot you don't decrease the players inventory, and if you pull one Coal from a "sequence" slot you don't increase the players inventory. After all, it's just the blueprint for what to sequence out, not actual material.

XR-1 vs XR-2
The difference in the amount of resources needed to manufacture the XR-2 Robot versus the XR-1 robot is so huge that it's
much more economically to make several XR-1 robots instead of the XR-2 robots, considering the rather small improvement in performance of the XR-2 over the XR-1. The XR-1 Robot is probably overpowered based on the cost to make it. Maybe the amount of components for the XR-2 robot is a bit high, does it really need 6 x Disintegrators, 20 x Compact Storage Storage Cells and 8 x M12 Electric Motors. I calculated the resource costs for the XR-2 to 201 x Copper Bars, 141 x Iron Bars, 170 x Stainless Steel Bars and 35 x Glass Bluegraton compared to the XR-1's 1 x Grey Cast Iron Bar, 4 x Copper Bars, 2 x Bronze Bars, 2 x Stainless Steel Bars and 4 Iron Bars. Just wondering how much will the higher level robots need to be made?

Voxel Materialize/Dematerializers.
These two are also require very large amounts of resources to make. Maybe lower the number of Disintegrators/Atomic Materializers needed.

Atomic Compressor.
Considering the amount of stuff it can store it's way to cheat to make. Maybe make a simpler version that has a very limited amount of slots.

Sequencer.
Also way to cheap to make considering how powerful it is. (This is probably the most powerful item in game.) It can store huge amounts of resources, and since you can manually put stuff into it's "Input" area, you can very easily automate production by putting all the needed parts in the Input except the last BlackRock Blue and then just feed it BlackRock Blues to make it sequence out all the needed resources.

M11 / M12 Electrical Motor
The amount of Copper Wire needed to manufacture is a bit high. Maybe change the amount of Copper Wire you get for every Copper Bar when you make Copper Wire to compensate for that.

Jet Engine.
Seriously?? 1 x Axel and 16 Iron Bars? This should probably be one of the most expensive items to make in the game.

Some pictures of my Ore Smelter and Blue Glass manufacturing facilities, my multi purpose manufacturing area and a stairway to heaven.

And yes, I have 'customized' the BlackRock bitmaps since the world was a bit to dark and depressing for me, and added the descriptions on all the ores so I can tell them apart. I mixed up Chrome and Nickel to often.

A script for the programmable computer that will dig/build stairs for you. The shape of the stairs are stored as arrays in the script. Each array represents what the computer will have to do to build 1/4 of a revolution of the spiral staircase.

With some work you can add your own stair shapes. Only your imagination is the limit

The script will NOT save it's state on a save/load since it uses variables to store it's state, and I don't know how to save them.

Configuration
MineNearOre: Change if the computer should mine blocks outside of it's programmed path when it finds them. 0 = No, 1 = All none BlackRock block, 2 = Usefull minerals, +4 = Also 'follow' the ore. (it will walk back the same way and continoue it's build where it left off)
MaxMineFollow: How far it will walk of while mining ore.
RefillOre: If it should fill those empty slots created from mining ore outside the programmed path. 0=No, 1=Only Floor, 2=All.
Rares: What blocs are considered useful ores.
VoxelOrder: The order it should use BlackRock blocks to refill holes with. Based on the order of which the block appear on the central blue plains.
Path: Defines the shapes of the stairs created. It's a table that contains arrays, where each array is one shape. (Example. One builds the floor of an stair up into empty space.) Here you can add your own shapes.
PathNo: What variant to use from the Path table. Here you specify the index of the array in the path table.

When you want to start building the stairs you place the computer at the bottom one off the corners of what will be the central pillar of the spiral stair. If you need to restart/continue building a stair you can place the computer at the bottom of any corner of the central pillar and it will automatically calculate what rotation to start from based on the level (GetY) it is placed on.

Is there a way yo use then Voxel_Load and Voxel_Unload to store the state of variables when the game is saved and loaded?

When I place a computer it automatically starts executing script 0.nut and also seems to execute the Voxel_Load function. But if I change script in the computer dialog and hits "Load / Compile" the Voxel_Load function does not get called for that script. That doesn't look correct to me.
