05/07/2012 Toady One Things are continuing along. A track stop can now be set to dump contents in a direction when a cart arrives. This action does not need to be powered. This includes liquid dumping. Track stops have optional low friction, so you can set contents to dump without having to restart the cart manually. There's a hang bug somewhere in the system I'd like to stamp out, and a few other random issues, but it's almost ready to go.

So, what are you guys planning to do with this?  Just quantum stockpiles, or elaborate magma/drowning traps?  Or perhaps people will just use minecarts as projectiles and make some kind of minecart siege engine to shoot minecarts into their enemies?

[GhostDwemer]

I was planning on using minecarts to round up all the stray minecart related threads and deposit them into a bin so they are easier to keep track of.

How does that even relate in any way to what was said in the blog

At best you can make a haphazard magma rain over some area. And even then what's the point of a few single pools of the stuff?

[bombzero]

well tbh, I see this as a cheaper way to get magma up to the surface.

as of right now a pump stack takes more to build then you will ever get out of having it, so a simple stone carved track with a magma proof minecart could act as a dumping system to a magma storage near the surface.

[imperium3]

Depends how much fluid you can put in 1 cart. If it's 1 unit then it's not all that great (though with enough carts...) but if as I suspect it's 7/7 then it's extremely easy to weaponise.

But as bombzero said, the biggest advantage is that it's a cheap and easy way to obtain and use magma. Cheap, that is, if you don't mind having your dwarves push the carts to the surface, as installing enough rollers to do it automatically could be almost as time-consuming as building a pumpstack, since you still need to power them.

So yeah, may not be that cheap.

The up ramp could be a 3x3 spiral:

Code: [Select]

v, ^ - ramps
+ - track corners
* - gear
R - roller

even z levels
#####
#+^##
#R*##
#+v##
#####

odd z levels
#####
##v+#
##*R#
##^+#
#####

I don't know how effective rollers will be, but it's likely you won't actually need
one at every level, so you could have unpowered levels with a vertical axle in
the center.  You could also have lever controlled stopoff points that can take a
cart out of the spiral.

This would only use at most two mechanisms and some carved tracks per level,
and the only part that needs to be magma safe is the cart itself.  Much much
easier than a pumpstack.

if we can get wear levels in the stockpiles for clothing, this would make dumping of used clothing into magma or whatever easy.

[Mrhappyface]

Are the carts unidirectional on a track?

[Brewster]

I'm just jacked you can assign stockpiles to workshops!

Have you read the older entries?  Minecart collisions are already in, as is derailing.  And momentum transfer.  So it *should* be very possible to queue up a line of carts, ram a cart into the back, and have that send one cart in the front into an acceleration zone where it shoots out of wherever.

Depending on how all the links and things work and take power, this should permit more or less automatic minecart-based siege weapons.  And I already have a name:  Dwarven railguns!

I wonder if mods will be able to make the carts travel at any significant fraction of the speed of light?

[Torham]

hmmm... so... sufficiently prepared slaughter landing area and loading/accelerating mechanisms for minecart railguns could potentially finally be enough power to kill all the FUN down below. It would be actually survivable. Maybe make the feeding mechanisms shoot water and magma filled minecarts alternatively for obsidian death or just fully loaded with gold ingots for maximum kinetic energy.

[terko]

As long as it can be controlled by a LEVER, it's all fine, no matter how it works.

[Telgin]

I'm looking forward to the ability to transport magma this way.  I've never finished a magma pumpstack, and even if this isn't a faster way of getting magma to the surface, if it's an easier way I'm all for it.  You'd have to set up some means of getting magma to fall into a minecart, but that should be relatively simple compared to engineering a pumpstack.

The only real problem with it I can imagine is I still won't really be able to make a magma moat out of it since it will probably work pretty slowly, and magma would evaporate faster than I could fill the moat.  Still, one can dream, and it's a way to set up magma forges close to the surface or on the surface.

Segment the moat using bridges. If one cart dumps 7/7, start with a 3x1 segment, which will give you two 2/7 tiles and a 3/7. No evaporation. Two more carts fills them to 7/7, open the bridge to reveal a 3x3 segment, which should all be 2/7 or 3/7 deep. 6 more carts, open the next bridge to reveal a 3x9 segment. 18 more carts, open the next bridge to reveal a 3x27 segment. Keep going until you're full.


If you want a 1x passage, 1x3, then 1x9, then 1x27, etc. using floodgates. Make them non-magmaproof and the magma will destroy the evidence of your trick.

I'm thinking of using carts as part of a Dodge trap... get the Gobbos to try crossing a trestle, they shoot carts at them... easy to dodge, by jumping off...
