I was thinking about dwarves and their love of mechanical things *You have to admit this cannon is cool ->
http://mythicmktg.fileburst.com/war/us/herald/images/betajournal/WAR_betajournal-2.jpg and I came up with a transport system in my head that is fairly low tech but could still haul a fairly good load at decent speed.
The bad part about this is it would need to add more items to the game in order to be somewhat realistic and could easily become unbalancing if care was not taken.
Anyhow. The basic design is a player lays out a track on the floor of their fortress and when a dwarf needs to go some where he steps on the transport system and it calculates the time it takes for him to get to his destination.
After that calculation is done the dwarf is held in a buffer until the time has elapsed and then comes off the line wherever he is supposed to come off at.
This will reduce unit pathfinding costs as the path only needs to be calculated once.
This will also reduce graphics usage as the dwarf is not shown carrying his stone anymore.
This will allow fortresses to be built more effiently as stockpiles and workshops can be connected and perhaps reduce the number of haulers that one would need, or make the ones you have work more efficiently, while once again at the same time reducing lag.
Now for the complicated part... How this monster is built.
The required components.
#1 Fine tubing - This is made at the metalsmiths forge at the ratio of 15 for every bar of metal used. These can be made out of Copper, bronze, iron or steel and take 15 times as long as a normal workshop item. Since in my mind it would also be far more difficult to make fine tubing they should also recieve exp bonuses while doing this task.
#2 Drive rods - These can be made out of iron or steel at the metalsmiths shop they produce 5 per bar of metal and require 10x as long as normal metal objects to create
#3 Springs - These can be made out of iron or steel at the metalsmiths shop, they produce 10 per bar and require 25x the time of a normal object.
#4 Fine mechanisms - These are machined from a mechanics workshop, do not require a fuel to produce, and produce 10 per bar requiring 10x the time. They can be made of copper, bronze, iron, or steel
#5 Rope - Pig tail rope would be fine
#6 Rails - Produced from iron or steel at the metalsmiths shop, 4 per bar at regular speed.
#7 Air Tank - Produced from copper, bronze iron or steel, Produces 3 per 1 bar of metal takes 3x as long to build.
#8 Accelerators - These can be assembled in a mechanics workshop and need A rope, A drive rod, a spring, fine tubing, and 2 fine mechanisms.
#9 Rail ties - These can be assembled at a masons shop using stone, carpenters shop giving 2x per piece of wood, or a metalsmiths shop using iron or steel giving 4 for every bar.
Now for the actual transport system itself.
#1 The rails - Each segment would need 1 accelerator and 1 piece of fine tubing if it is under 5 tiles long or 2 if it is up to 10 long, and 1 rail and a 2 rail ties for every length of track
#2 The Compressor - This is a pump that requires 100 units of force to operate * so you would need 2 water wheels to run one because they only give 90 a piece* This produces a 100 units of air power every few seconds.
They need 2 drive rods, 3 pieces of fine tubing, 2 fine mechanisms and a block to build
They can also be dwarf powered but they would only produce 10 units of air power instead of 100. Or they can wear a dwarf out really fast.
Also would like to have a boiler option and maybe a magma boiler option as well
Also if a player needs more power they can build more compressors anywhere along the lines and it will help power it.
#3 The air tank - This is where the force is stored, when placed next to a compressor it can store up to 5000 units air power. Uses an air tank, a fine piece of tubing and a block to build. More of these can be added if the player believes its warranted as well.
#4 Car Depot - This is just required for the operation of the transport system. It Requires quite a bit of metal as I am abstracting building the cars inside it for the system and a couple blocks to build.
#5 *Forgot this one* The lift - For traveling through Z levels. Needs everything a 1 square track would need Plus 4 drive rods and 4 more fine tubes.
All that building will Net the player a really really neeto dwarven transport system.
The energy used is dependent on the weight carried by it, so rock moving will take a lot more air power than wooden flute hauling but there will always be a minimum due to the weight of the dwarf.
Probably should produce dwarf happy thoughts as well because it is a massive project to undertake... and I know it would produce a happy thought in me to not have to lug a stone block 5km to the masons shop.
