[Mod] Carts [carts]

[RealBadAngel]

mesecons are a must-have for some uses
this is one of them

[PilzAdam]

In the last few days many people complained that I should make the carts mod better.
So I started to rewrite the mod completly from scratch. Here is the result:
https://github.com/PilzAdam/carts/tree/carts_2.0
The features:

• The carts is not moving on its own, you have to push it
• Driving on hills is now working; the cart gets accelerated when driving down a hill and decelerated when driving uphill
• The code is much more lightweight and billions of times faster and cleaner than the old one
• It transports the player correctly (no lag or something)
• There are currently no switches or chests or any of the features of the old mod (like mesecon support); Im working on this

It requires at least current 0.4.4-dev version of Minetest.

EDIT: Oh, and its more stable than the old one.
EDIT2: You have to use any tool (like pickaxe) to remove the cart while punhing with hand or nodes pushes the cart.

Sweet! I will surely test this when mesecons support is available. :D

Awesome. I tested it; hills are much smoother and more stable. I got it to derail a few times on a really complicated track with lots of hills and turns, but that was really rare.
A bug I could confirm: it gains more momentum than it loses. Make a big 15-20 block high V-shaped track and make a cart run back and forth from a height of about 3; the cart will go higher each time and eventually reach the top.

This is not a bug. Its a gameplay decision I made to allow people moving on long tracks.

PilzAdam, i downloaded the carts 2.0 that you made. However the crafting recipe will not work, i even tried the giveme
command and the last thing i used was creative mode to get the cart, but still no luck.
I am using the minetest-0.4.4 build with 3d players (that i have compiled on github) I also use linux. Any help?

Are you sure you installed it correctly?

Yes, Ounce i downloaded the folder i extracted it, then named it to carts, then i moved it into mods/minetest

Another major update to the carts 2.0 branch: https://github.com/PilzAdam/carts/commit/d85c46f778922a0abcdc7ff476dcdc4509a4ab2a
It makes the code a lot more stable by recalculating the positions that are passed since the last server step. So it corrects the position if derailed.
It should run fine on servers now, but I havent tested it.

Just tested on VanessaE's server and confirmed that it works really good on servers now.

Did something make the carts go faster, or take corners faster maybe? My roller coaster feels like it's in fast-forward now.
EDIT: Also, at a point where the rails crossed, the carts always went straight, but now they turn a random number of times before going straight.

The maximum speed was increased.

[PilzAdam]

And mesecon support done for 2.0 branch.

[PilzAdam]

Carts 2.0 added to first post.

Can you make the cart have the same nodebox as the original version?

[PilzAdam]

Can you make the cart have the same nodebox as the original version?

No, because the attachment code of the 3D players is still buggy and the players get smaller if they are attached to an nodebox cart.

[Zeg9]

No, because the attachment code of the 3D players is still buggy and the players get smaller if they are attached to an nodebox cart.

I'm wondering, what about a model ? Would the players scale down too ?

Models would work. So if anyone would provide a model I will gladly add it.
Also 3 animation frames would be nice: One normal and 2 with pitch 45° and -45°.

[PilzAdam]

First post updated.
The carts 2.0 branch is now the default master branch. The old mod is now in the old branch.

[PilzAdam]

Zeg9 made a model for the carts. You can test it in the model branch on GitHub.

@Zeg9
Can you turn the animation in the correct way and also add the third frame for the flipped pitch? It would be also nice if the cart would move a bit up in the pitch frames, so that you cant see the rails at the bottom of the cart.

[VanessaE]

PilzAdam: -1 for that - rails should not be hidden by the body of the cart. If anything, the cart should appear to sit right on top of the rails via a set of wheels.

[Doc]

I agree.

Bug:
The cart seems to glitch out (goes infinitely in the direction it was going, even through blocks) if the track it is on changes while it is moving.. Chunk loading stopped working and saving the world failed...

that works really nice, the cart is sideways when it goes up the rails though, anyways nice work, you should make it so you can link carts together!

[jojoa1997]

Having a booster rail would be nice. My villages that are connected by rail rods are now longer to get to with me having to get out and push, get out and push, get out and push.

[VanessaE]

Place mesecons torches or power plants next to the rails about every 10 nodes or so. Each will give the cart a small boost. Run a length of wire along the rails and give it power and it'll give the cart a large boost.

[Zeg9]

Here is a model that works fine with "slope" rails:
http://ompldr.org/vZ29ycQ
Although it doesn't work when going down, it works great going up
Also, I've moved it a bit up in the "rotated" frames.
What do you mean by "add the third frame for the flipped pitch" ?

EDIT: ompldr shows it as a text file, just save it as .x
EDIT2: try this init.lua http://ompldr.org/vZ29ydg
Animation works with carts going down too

I crashed my server. Mile long boosters this morning.

I dont want to change the yaw when moving downhill because the player faces in the wrong direction in this case.
Just add a third frame that is exactly like the second frame but flipped horizontal by 180°.

Yeah, sorry. I actually added a third frame but blender wouldn't export it... I forgot to change the animation "size"
I'll send a model working with normal init.lua soon

EDIT: It seems the problem wasn't that... I'll try to fix the model as soon as possible ...

[Zeg9]

New model:
http://pastebin.sabayon.org/pasties/store/11564/cart.x
Should work without modifying init.lua
