HERDING LIVESTOCK TO MARKET

[GarryG]

UPDATED: 27 April 2023

I have started making a road vehicle set without vehicles

So far there is:
* livestock that can be herded on the roads.
(Basically designed to take your livestock to the markets before road vehicles where invented)
* People riding bicycles.
(Will carry people as if the bikes are rented and when reach the bus stop they swap riders. Or can carry mail as if delivering mail).
* Military people marching. (Yet to add the military bands).

How to use:

* I designing 2 versions of these so have choice a small herd that will block just 1 lane of the road or a larger herd that will use both lanes of the road.
* The livestock when loaded have animals, people and dogs herding. When empty only have the people and dogs to return to the farm.
* There are also eye candy version for those who just want the animals roaming around the roads.

Intend to add:
* Pigs.
* Horses.
* People on parade.
* Wonder if I try doing marching girls?

Suggestions be appreciated.

McZapkie for the horses.
(From his Polroad Vehicle set .. took them off his horse and carts)
javelinnl for the bicycles.
(He has a set called "velo" where he has a single bike rider roaming the streets).

The following have help with ideas and showing me how they used what I did so far:

A livestock herd coded as a vehicle would take the same amount of space on the road whether it's full or empty. This could be a bit of a problem.

Also, livestock herds usually don't respect the traffic lanes. They often occupy the whole width of the road, as limited by fences or other obstacles.

[Kruemelchen]

I think the idea is pretty neat!

I thought of coding this with cattle and sheep one day, just haven't come around to draw the animals yet (I always do this in extra zoom). But I can definitely assist you with the code

A livestock herd coded as a vehicle would take the same amount of space on the road whether it's full or empty. This could be a bit of a problem.

I would make the "herd" an articulated vehicle of several herd segments. It could be possible to adjust the length of the segments depending on the cargo like this:

Code: Select all

switch(FEAT_ROADVEHS, SELF, herd_length_cargo, cargo_count) {
	0:		0;
	1..3:	1;
	4..6:	2;
	7..9:	3;
	10..13:	4;
	14..17:	5;
	18..21:	6;
	22..24:	7;
	default:	8;
}
switch(FEAT_ROADVEHS, SELF, herd_length, position_in_consist) {
	0:		1;
	default:	herd_length_cargo;
}

Thanks for the feed back.

I think it will look good if they take up all the road like in real. Not sure how road vehicles will react when they become available. They might just have to wait till the animals have cleared.

I also like to make a extra road called a stock route so just the livestock can travel on it. But the livestock can also go on other roads.

Maybe Georges animals might be a good start till get it working properly and maybe adjust later..
That be appreciated if you can help. I hope to start on this project in a day or 2. Busy today as got medical appointments.

That sounds like a great idea. I see in the HEQS set some vehicles have 2 trailers. The problem will be when returning to the farm. We don't need to bring the livestock back to farm. Just the people herding who was herding the animals.

Cheers all .. I got to go .. got an hour to get ready before I go get the bus.

Or you will get a lot of minced lamb, if not

I once got caught in a herd of sheep while driving around the Etna in Sicily and it is - hm - interesting. Luckily the car was rented

When I work for railways had to herd the sheep, cattle and pigs on and off the wagons from the stock yards.

I think sheep are more intelligent then some car drivers these day

What speed should they travel at? Maybe sheep and pigs 5 mph (8 km/h) and cattle a little bit faster maybe 10 mph (16 km/h).

See if I can start making the templates this afternoon or in the morning. Like to make them fairly wide so that can take up a lot of road space.

[Captain Rand]

What speed should they travel at? ..........

Human walking speed is about 3MPH, so if you have a shepherd guiding sheep on foot he's probably walking at a gentle stroll, which would be even slower. Cowboys on horseback (still walking) might be a bit quicker, but not by much.
Nothing in OTTD is really in scale though is it?, so you don't really need to be dead on accurate, but I think even 5MPH is really pushing it.

I think you may run in to another problem though. Stockpiling at the source farm. Your "vehicles" would be so slow that by the time they return empty to the farm that farm may have already gone through more than one cycle of cargo generation. The answer to this of course is simply to use more "vehicles", but then you could end up with a constant stream of "animals" on the road which just wouldn't look right.
You could just give each "vehicle" a high cargo capacity, but then it's impossible to predict how high this needs to be. There's too many other factors to consider. How far is the destination? How long is travel time? What industry set is being used?
These will all influence production rates.
If left at the source for too long, or source to destination is too far, then you could also face the problem of cargo aging.

I'm not trying to discourage you, I think this would make a brilliant GRF.

As an example, in one of my games I had a rail station serving three nearby farms. The farms were just outside the catchment area of the station. I linked them with the distant station function so the station was now collecting cargo directly from the farms. Then I made some dirt roads to link the farms to the station to give the illusion of livestock being herded. I had to use my imagination of course but that's half the fun! I used trucks with transfer orders for the other slightly more distant farms in the same cluster. I'd have absolutely used your GRF had it been available then for the closer farms with transfer orders rather than directly linking stations.

As always, I look forward to seeing what you come up with!

Pete.

Getting a suitable speed will be a problem .. be a matter of testing different speeds to get something that looks good.

But at least we will have a way to move livestock until trains and trucks become available. Fun part whan trains do become available can herd the livestock to nearest railway station to load them on to the trains to continue their journey.

Kruemelchen and McZapkie both did a "horse and cart set that is available for those who like to start their game 1700s and earlier and they carry livestock. These will get a small number of livestock to markets a wee bit quicker then herding. Depends what wagons you use can carry between 2 to 24 head of livestock. So you'd probably have a wagon train with many wagons heading to the markets. I imagine small amount of sheep and pigs would have been taken to market by wagons, but can't image a big cow being loaded on to a wagon.
I think having herds be more realistic and fun.
To have large herd I now wondering if I code them as train and have a special train track designed like a stock route. That way can have livestock as engine and a string of carriages to move large quantities at a time.

So next question is do I stick to the herding by road idea or try the herding using a special stock route.

I think you should code it as a road vehicle, livestock drives along highways can present an additional challenge for existing road vehicles. It also happens in the modern era.


Create it as a vehicles set, using shepherds/horses/dogs historically, switching to pickups in the present era as seen above.

Making them a road set will make the game so much more fun .. be a bit slow using them as mentioned but that the fun of it all. Even when trains and trucks become available I think they will still have a use. Interesting part will be seeing what road vehicles do when they meet the livestock on the road. Will they go around them or stay behind. Maybe run over them and make lamb chops

We shall see what happens.

Hope to do some to them over the weekend.

Cheers

[Captain Rand]

Yes. My comments didn't take pre truck/train games into account. I've never played a game that started so early (it's mostly about the trains for me).

Fun part whan trains do become available can herd the livestock to nearest railway station to load them on to the trains to continue their journey.

Which is exactly the way I'd use it, as I said in the example I gave.

As an example, in one of my games I had a rail station serving three nearby farms. The farms were just outside the catchment area of the station. I linked them with the distant station function so the station was now collecting cargo directly from the farms. Then I made some dirt roads to link the farms to the station to give the illusion of livestock being herded. I had to use my imagination of course but that's half the fun!

I'd have absolutely used your GRF had it been available then for the closer farms with transfer orders rather than directly linking stations.

Definitely road. Could you also make the "vehicles" compatible with the dirt/unmade roadtype?

Pete.

[GarryG]

Yes. My comments didn't take pre truck/train games into account. I've never played a game that started so early (it's mostly about the trains for me).

Me too .. I always been train mad. What first got me interested about the livestock is like to be able to herd them from farm to a railway station for loading on train, and then got the idea these should be available as early as possible way before trains and trucks. So the idea developed from there. Maybe nice to also herd the sheep to a shearing shed to shear and produce wool

Definitely road. Could you also make the "vehicles" compatible with the dirt/unmade roadtype?

I will put as many road codes in as I can so they can go on almost all the roads. So if any one can help and start collecting the road IDs be appreciated.
Be fun the livestock going through the towns But maybe keep them off freeways.

Cheers .. my bed time now .. hope tomorrow start doing something towards this idea.

Cheers all

[odisseus]

There is quite a number road types which should be forbidden for livestock herds. Highways, pedestrian zones, roads with ground-level power supply, to name a few. Of course, there also are mock waterways.

I am working on an implementation for my horse cart GRF, but the variable length doesn't seem to work (it only updates in the vehicle info window, but not on the game map)
I'm not sure if this is actually supported
This is the code:

Code: Select all

// vehicles in the centre are the animal herd
// length dependend on cargo
switch(FEAT_ROADVEHS, SELF, switch_cart_herder_length_cargo, cargo_count) {
	0:		1;
	1..9:		3;
	10..19:		5;
	20..29:		7;
	default:	8;
}
// first vehicle is the shepherd dog
switch(FEAT_ROADVEHS, SELF, switch_cart_herder_length_1, position_in_consist) {
	0: 2;
	default: switch_cart_herder_length_cargo;
}
// last vehicle is the shepherd
switch(FEAT_ROADVEHS, SELF, switch_cart_herder_length, position_in_consist_from_end) {
	0: 2;
	default: switch_cart_herder_length_1;
}

Edit: The variable length actually works, but it seems to take a lot of time for the length variable to be updated, plus a visit in a depot is mandatory for the change of length to be visible on the game map. So I guess we have to live with fixed lengths

There is quite a number road types which should be forbidden for livestock herds. Highways, pedestrian zones, roads with ground-level power supply, to name a few. Of course, there also are mock waterways.

Kruemelchen has provided a list of road roadtypetables (above) .. if any of those any one thinks should not be included let us know.

Today I have the coding "example_road_vehicle" from NML examples to practice with .. I intend to change the sizes of all the templates. For instance vehicles facing North-South these templates are normally 8 pixels wide I intend to increase them to 12 wide same as width of vehicles from HEQS set. The normal size templates are not big enough to display a man on horse and a sheep. Definitely not much room for a herd even if the man was walking.

Shall see what happens if I can make the templates larger.

[odisseus]

I don't know those road types by heart, thus I'm afraid I can't help you with that. I just wanted to point out that allowing livestock herds to move on "almost all the roads" would be a mistake.

[GarryG]

Once we get them working shall see what roads we can and shouldn't allow them on.

I tried testing using the examples that comes with nml, but keep finding errors when trying to make a GRF from it.

So will have to find another road vehicle source.

Cheers

[GarryG]

I not winning with this project.

I been trying to just test a herd of sheep and try get the speed they should travel at.
But I can not even get them to load.
First I was coming up with year errors saying to start a game after 1925. And when start a game just after 1925 all I get is a bus.

Trying to set start date as early as possible .. I have introduction_date: date(200,01,01);

Any way it late here so I head off to bed.

I upload the source and maybe some one can show me what I do wrong.

Cheers

[Brickblock1]

I got it working, it seams you forgot to define what roadtype should be used. I set it to road which is probably the best that can be done right now.

[GarryG]

I got it working, it seams you forgot to define what roadtype should be used. I set it to road which is probably the best that can be done right now.

Glad it worked for you .. but it still not working for me.

Tried loading it with my normal GRFs and also I tried it on its own

Maybe it too early in the morning and I need to wait till I wake up properly.

Appreciate your help
