Super minecart push
« on: May 14, 2012, 07:02:11 pm »
So I have just carved a small, 18-tile long rectangular track to test minecarts, and I have a -saguaro rib minecart- on it.

Made two stops, ordered it to be pushed when empty.

Miner with average strength comes, touches the minecart...

And sends it speeding along the cart, making three turns and a half.. meaning easily 60 tiles. With a single push, making a minecart make more than 50m on flat terrain ? That was quite a strong push !  And now my miner broke his arm with a minecart he himself "pushed". And another went to play "push the minecart" and broke the same miner's leg.

ARGH GOD DAMN IT I HAD JUST STARTED MY FORTRESS. I don't even have any beds and it was my best miner and only mechanic. AARGH

Conclusion - who says we need more than a carved track and a few minecarts to crush a goblin ambush ? Also, minecarts are FUN. And we don't need lead ones to shatter gobbos in half.

Use Guide minecart instead of push until your railways can be secured. We don't allow pedestrians to stroll around on a freeway or a railroad, do we?
Guided carts are harmless and pass by dwarfs blocking their paths without any injury, but are much slower and tie up a dwarf guiding it. But a guided cart is still faster than a wheelbarrow since it hauls more stuff per trip.

yeah i thought "pushing" would be pushing along, not kicking a minecart with grand power.

Anyways, seeing the speed at how a minecart  can go, dwarven railguns will be promising !

Indeed... a cheap one from the start might not even need power, just dwarves to kick a few carts. Make a few stops in sequence, kick the front, kick the middle, kick the back. rapid fire down the same track.

Yes, I know, everyone is already thinking this:p

I've combined a minecart with the bridge of Kazarad-Dum. It's as awsome as it sounds

I had an above ground garden built in the grounds of my castle and two young dwarves spent time socialising there over the summer and at the end of the summer they were in love. Remember those long summers of your childhood? That first kiss in the gardens while crossbows dwarves shoot goblins above your head? The rain of dead birds as the hunters get to work? Truly Spearhills is a paradise.

I think it has more something to do with the fact that saguaro ribs are light as hell with Uristocrat's changes--almost as light, if not as light as featherwood.

Yeah, it's like you're kicking a paper mache object on wheels.

Try an iron cart or something, if that moves more than 30 tiles I'd be surprised.

Me: I developed a way to catch demons which shoot web, then I forced it to work in a sweatshop and shoot its magma-proof web at children so I can collect it to make clothes.

Friend: Holy shit.

Just to point out, Toady said that for the purposes of minecart physics, he was assuming 2m*2m*3m tiles.  60 tiles means 120 meters of linear distance.

Saguaro rib has a density of 430, while metals like iron have 7850, and gold has 19320. 

Considering as I seriously doubt that Toady has modeled in inefficiencies in work applied due to an object already starting up with momentum, I'm guessing that a "push" is applied as a singular impulse like hitting the target with a mallet to get it going, and that momentum is divided out by mass. 

Since gold is 45 times denser than saguaro rib wood, I'm guessing Toady faced a choice - either make gold carts not be pushed even a single tile, or make saguaro rib carts get pushed like they're on maglev rails. 

He went with the latter. 

EDIT: correcting my math.

Personally, I like [DF] because after climbing the damned learning cliff, I'm too elitist to consider not liking it.

Should be 120 metres.

... Yes... why did I divide instead of multiply...

Considering a standing dwarf is occupying one tile... then why are tiles 2x2x3m ? I always saw them as 1x1x2 since 40d.

dwarf can stand together on 1 tile

logic for 2*2
not so for 1*1

True story: In the year 2007: Surinder Singh Bajwa, the Deputy Mayor of Delhi, India, was warding off several Rhesus Macaque monkeys at his home and fell from a first-floor balcony, suffering serious head injuries. He later died from his injuries.

No, one dwarf has to lay down if they're both on a tile.
