[Mod] Carts [carts]

[Krock]

Well, it's already now possible to add own rails, it only needs some meta information about the acceleration.

[Sokomine]

There are always problems with carts on a server to some degree due to lag. I think the only way to do it properly would be to teach the client about rails in general so that the client can predict the movement of objects attached to rails. Handling rail switches would still require updates from the server, but most movements could be done by the client. "Rails" ought to be a very general concept so that things like tubes from pipeworks and the items shooting through them are handled by the same code.

Excactly. Also, the global step is not always the same and that's the reason I made my own fork of it. It seems to run smoothly now beause the position is not always sent to the player.

EDIT: Added rail switching by keys (used some lines of code by Kilarin)

I like this ;-)

Awesome mod! Great Job. Do you think it would be possible to add sounds?

[cHyper]

great mod, sounds would be a cool feature...

Added a patch which makes the player "sit" in carts. Please pull if you like, I think this is quite reasonable.

[sofar]

I'm a bit disappointed that carts are unmovable when you're inside of them. I'd rather see a cart be slow (e.g. max speed while manually pushing 4) than the current situation, since carts are just no fun unless you start building all sorts of mese-powered contraptions. Please consider making carts player-powered when attached (e.g. punching them while in one should just work)

Yes, I had the same "problem" and solved this with a few lines of code:

I hope PilzAdam merges the pull requests, some of them are very good.

[twoelk]

you could of course place a powered rail and connect a button to it by using mesecons or simply two blocks of mese. Hop inside and press the button. Not much unlike mc iirc.



ok could be done simpler but this one on VanessaE's creative server was supposed to serve four lines ... if I get it sorted some day

How do you remove the carts from the tracks?

[ExeterDad]

Shift+right-click

[TenPlus1]

Shift + Left-Click

[ExeterDad]

Yikes! I still don't know my right from left! Lol
Thanks TenPlus1

[Don]

The left and the right are always fighting. You 2 should be politicians.

[TenPlus1]

lol

[ExeterDad]

touché :P

Could you detect if the cart runs into a cactus (or other damaging type node) and then do minetest.drop_item(cart, ....) ?

That would allow anyone to build tracks that automatically remove carts from rails, build conveyor belts that reuse carts (e.g. vacuuming them up and then putting them back in a dispenser).

[12Me21]

Maybe the node breaker should pick up the cart (even though it's not a node). Having to crash carts into cactus to collect them (into an item transport system) seems so primitive and... minecrafty.

[lag01]

Maybe modify cart mod to sometimes check if there is rail under cart and drop cart if there is no rail.
Then you can use pistons to move rail under cart away.

Yeah, that should be good. Though it would be easier to make the rail just end (so the cart falls off) than use pistons.

I really don't like the piston trickery needed, since it forces you to put a piston, a vacuum tube etc. all close together which is hard to do. At least a cactus is a non-moving block.

just make the cart fall off the end of the rails.

Just think about it. How would a minecart break from hitting a cactus??

Actually, I don't like the fact that the carts stop dead at the end of a rail, and I would indeed like to see them shoot off.

Yeah, that would be good. However, wouldn't it be easier to make another rail to return the minecart to the start?

that would mean rails have to always be circular tracks. In the real world, rails stop, and quite often too.
