[Mod] Carts [carts]

we ask at developers some API for maintaining active
some object

[REQUEST] - locked cart / dropoff / pickup

CART - this cart only allows the owner to start/stop and pickup the cart
DROPOFF /PICKUP - instead of just throwing items on the ground, they are placed in a chest that only the player can access

What about with detecting of kinds of rails? Is it possible?

What about with detecting of kinds of rails? Is it possible?

What do you mean?

[Ragnarok]

I say about playing carts_straight_rails.ogg when cart is over straight rails, carts_curved_rails.ogg when cart is at the turn and carts_railway_crossover.ogg when cart cross the intersection.

The sounds are to long for that.

[Ragnarok]

The sounds are too long to play them on a single rail - I agree - but you can detect whether the rail is changed, and then play the sound carts_curved_rails.ogg or carts_railway_crossover.ogg for a while according to the type of rail. Over straight rails should be played carts_straight_rails.ogg. The question is: how to detect rails?

This is possible. Rails use the param2 variable so you can see wether they are curved or straight etc.. And with the get_new_direction() of the cart you can simulate the next 4 to 5 steps so you can detect the rails and check wether they are curved etc.
But I dont want to add this. I want some sounds that are played randomly.

As you wish. I just care about realistic sound.

Besides, there is nothing to stand in the way the default soundtrack consisted of randomly generated sounds while other sounds are played after the discovery of appropriate events.

Yes i know but i like the sounds as they are.

Is it possible to store the items in the cart as inventory? It looks strange with the items teleporting around...

[PilzAdam]

Is it possible to store the items in the cart as inventory? It looks strange with the items teleporting around...

No its not possible.

[graphics boy]

This is realy strange because in line 390 if init.lua the method is_player() is not used. Try redownload.

I tried redownloading it but It still had the error

Are there any other cart mods?

Could you please post the error message again. It is not possible that the error is in line 390 of init.lua
There is a vehicles mod but it is laggy.

Do you have latest version (29) of carts installed?
Do you have latest version (0.4.2-rc1) of minetest installed?

[graphics boy]

version 28 of carts
version 0.4.dev of minetest

[PilzAdam]

version 0.4.dev of minetest

Wich 0.4.dev (0.4.2-rc1 is latest)?

[graphics boy]

Minetest-c55 0.4.dev-20120606

[PilzAdam]

Minetest-c55 0.4.dev-20120606

This is maybe too old. Try a newer version.

[PilzAdam]

The carts are now 3D.

I think I may have some input. n.n The minecarts in Minecraft were rectangular boxes, and these are square. Now, let me just say that I don't really care about the shape, but I was considering some general ideas about the carts:

Make 3 points within a rectangular minecart.
<back point (follows track)><player point(stays between the back and front points)><front point (follows track)>

Doing this could (in theory) make a smoother looking minecart, and possibly eliminate some of the lag in the cart's player movement. Just an idea, but thought it might come in handy.

This wouldnt fix the lag when transporting players. Its an engine thing and I cant fix that in my mod.

Awr... :< Well, would the points at least make a rotating, elongated cart?

The cart is roatating but you dont see it. You can change the visuals of the cart by changing the nodebox in box.lua

Ooh! Thanks a ton! ^-^

Hey PilzAdam,

I've been playing around with code and I've developed an "automated" furnace that allows the cart to drop stuff into it.
