(OpenTTD) North American Road Vehicle Set (NARVS)

Post by NekoMaster » 20 Jul 2010 21:24

~ North American Road Vehicle Set (NARVS) ~

Hello and welcome to my thread for my in development North American Road Vehicle Set or NARVS.

This set aims to include many North American made road vehicles (mostly trucks, larger goods vans, and long awaited LCV's (aka road trains))
This set is set to include truck from 1900 to present including prototypes for possible future vehicles if enough information can be found.

For now its only me working on this set as of today (July 20/10) and I'm going to need help getting information and pictures of North American road vehicles like trucks and goods vans. Help would be very much appreciated and your contribution will not go un-rewarded, as anyone who can deliver will be able to beta test the set when it gets to that stage before the public can.

Why end after 1990? That one: http://autoline.com.pl/sf/ciagnik-siodl ... 23300.html was produced in 1993.

I'm interested in which industry sets you are thinking of supporting?


I have a model T van sprite which is currently in BRBV which you can have if its any good to you.


This page has lots of lovely pics of early trucks - bit short on performance data tho'

I never thought COEs were around that early. Nice array of configurations too.

Would this set include trams?

If so, would you classify interurbans as trams? (I would). The interurbans in the NARS are decent, but I think that if they were trams, there would be a much larger incentive to use them.

Also the Electroliner would be a welcome tram addition.

Once this set can get coders in the scene then Ill think about adding better support for ECS and FIRS, for now every thing will be done in Grf Maker :( So for now anything other then the defualt cargos will get generic load sprites (like generic crates or containers or geyish)

Also if anyone can, could someone(s) find me some Cement trucks, as I may include cement trucks to carry goods\ECS cement\FIRS engineering supplies

Also, I may include trams but interurban's are more or less electric rail buses, yes I know that some interurban's did run on tram lines.

Edit : Some specs for two powerful internaional trucks (International is a US company)

I'm using GRFmaker and supporting FIRS. I couldn't code a set to do both FIRS and ECS tho'

On the tractive effort calculation problem:
Tractive effort = mass * speed gained per time(acceleration). Mass is in kilograms, speed in meters per second, time must be in seconds.

For example, if a car weighing 2 tons accelerates to 27.7 meters per second(60 mph or 100 km/h) in 20 seconds, the tractive effort will be 2.7 kilo(thousand)newtons.
The calculation in this case is 2000 kilograms * 27.7 meters per second / 20 seconds.

However, OpenTTD's value(the one in the NFO) = actual tractive effort / possible tractive effort * 255, where the possible tractive effort is ten times the vehicle's weight.
That (integer)value would in this case need to be 2.7 kilonewtons / 20 kilonewtons * 255 = 34(.425).

The only problem here is that you need to guess or look up the vehicle's acceleration. As I am not any further advanced than(pretty wimpy) tenth grade physics, I can't think of a better way, though.

I'm largely set the TE (and sometimes the power too) to that min value what is enough for the vehicle to reach it's maximum speed with realistic road vehicle accelration. See Bob's set, the black cab can go with 80 km/h as the data said, but it cannot be go faster than 69, because it's low TE and/or low power.
I hope I write that understandably...

Can we/I see a pic of the base model?

And some constructive criticism:
-front and rear lights are missing
-front bumper is missing
Othervise it looks good, it's nice to see more and more road vehicle projects!

Bumper is there, its just too small to see properly and same with the lights, unless you wanna give it a whirl and help fix it

Btw, heres the base of a 1983 Ford F9000

Edit : heres the truck and first NARVS grf :3

In most cases the default value will be fine, e.g. for a standard rubber tyred truck where most of the weight is over the wheels.

There are some special cases, such as:
- bulldozers / tracked vehicles
- vehicles where a lot of the weight is not applied to the driven wheels
- trams (metal wheels on metal)

For these, I tweak values until I get the gameplay effect I want. I set up a test game with various slopes and run loaded vehicles to see how they perform. I use the default 'steepness' setting for this.

Nice to see you ship a grf Neko :)

I modified it a little, if you don't like it just don't use it.

I don't know if it makes any difference - and it has to be said I'm no expert - but the diagonal dimensions of the green back bit is 8 pixels in one diagonal and 10 in the other. Also in the diagonals the rear is 5 pixels high but horizontally its only 4 pixels high

I'll reduce the weight in the next release from 2t to 1t
