HEQS release thread: viewtopic.php?f=67&t=37912&p=698294

Original Post (June 2008)
I am a big fan of special vehicles: trucks, tractors and heavy equipment for construction, mining, forestry, farm and other off-road use.

This equipment would fit well into a niche in TT/OTTD: feeder service. I extensively build feeder services to consolidate the output from several industries to a rail station, and I figure I'm not alone in playing that way. The benefits of feeder service are:
  • Improved station ratings and industry production due to regular small pickups by RVs
  • Can use longer trains which are more efficient on track usage and running cost
  • More realistic (for those who play that way)
  • More vehicle/route optimisation (for those who play that way)
  • More fun/eye candy (for those who play that way).

We have some great road vehicle (RV) sets already for highway use: GRTVS, a partially complete UK (HOVS) set, and George's Long Vehicles. It would be neat to have off-highway equipment to use as well.

I am proposing to create the following list, which would be relevant from about 1975 (older vehicles could be suggested for earlier in the game):

  • Articulated 6x6 dump truck (ADT): mineral products.
  • Heavy haul mining truck: mineral products. This would have to be a small version due to scale issues.
  • Logging harvester or forwarder: wood / lumber. Great for getting from the cutting zone to the loadout.
  • Heavy Industrial Transporter: any cargo, but intended for steel, paper, copper, goods. Don't know much about these, but the key thing would be to design them to match scale and offer something different to regular RVs (high capacity, low speed, high purchase cost, low running cost).
  • JCB Fastrac + trailer: any cargo, but intended to get farm products to the elevator (35 tons at 50 mph!)
  • Foremost vehicles: eye candy cos I like them, but can carry any cargo including passengers (slowly!), realistic for oil fields in snow and desert, and tourists. Would like to include Delta, Nodwell, Terrabus.

Okay, so it's easy to make a wish list, how about putting my money where my mouth is: a single view of an ADT.

This is the first time I have drawn a TT graphic. I think it's ok, but is a bit too realistic - needs the colours softening. I am not familiar yet with how the TT pallette works and would be grateful for any advice (I do have Oskar's example pallete).

This truck would need to be articulated, but would work well with how the RV articulation functions in TT. I am not able to code GRF files, and I am a bit too busy coding in real life (python, html, css) to get my head into GRF coding! But I am prepared to draw (as far as my abilities take me), so if any coders want to lend a hand it would be greatly appreciated.

Other comments:
  • I wouldn't want the set to be huge or complex. It's not intended as a complete RV set. I would rather have something finished that is fun and useful than a long tracking table which becomes overwhelming (I'm sure some of you have faced that before) ;)
  • The intention is to put some extra variety in the game, I would look to balance reality with gameplay. The vehicles would principally be realistic, but often not based on any specific model, more a blend of what's typical.
  • There's room for other suggestions - but they've got to be useful in the game. More farm tractors are an obvious choice. Of course everyone has their favourite, but I'd probably just blend a few together, some people get passionate about tractors, I don't want the set to become a homage to tractor history!
  • I'm drawing with realistic colours, but it would be very interesting to see how company colours could be applied - I'd prefer a grf parameter to randomisation, but either could work.
  • I'm not sure about dimensions. I have the bounding box from Purno's tutorial and have used that as the limits. Can sprites be bigger? George uses bigger sprites, but the side-effects can be a bit odd at times as he says in his tutorial.
  • To be really useful, this grf may depend on OTTD's increased vehicle limit. I've had the idea for a long time, but my understanding was that RV IDs were very limited. Now that limit is being removed (for OTTD) it looks worth putting some time into this (sorry to Patch players in advance I guess).

In the long term, it would be neat to add another class of roads to the game: off-road trails. These would:
  • Be very cheap to build and it would be possible to build them on almost any combination of slopes within the limits of the tile engine (advice?)
  • Only allow off-highway vehicles (which could also travel on-highway, similar but slightly different to the way RVs cannot travel on grass tram tracks).
  • Would be dirt in temperate and desert; ice-roads above the snow line in arctic.

However a new road type is not necessary for this set to work, and it's extra complication that can be ignored for now - if there were good grf sets that could use such a feature, perhaps devs might consider it?


cheers,

Andy

I am considering adding a parameter option to HEQS to hide some of the vehicles.

For example, some of the bulldozers could be hidden. This would reduce clutter in the buy menu and make it easier to use.

Is this something that you would find useful?

In my opinion, you shouldn't worry about that. The buy menu is not that crowded. This is just fine from my point of view.

In this point I agree with Voyager. If you need a specific vehicle, the buy menu has the filter options ready at hand. Don't make your life unnecessarily hard ;-)

Andy, if you're up to doing something with this set, I suggest you add a tank to crush AI vehicles... :twisted:
Just kidding. Great job! :D

Is it possible to make HEQS combatibile with German Road Vehicles set?

It already is. It's the German Road Vehicle set which isn't compatible with HEQS. More on this in the German Road Vehicle set topic.

EDIT: oh, you already doubleposted there. Never mind this then :)

I discovered another bug (I'm sorry to always find just the errors):

And here's a small sprite error :roll: :wink:

Looks like you'll be fixing quite a few minor bugs, Andy
BTW, looking forward to the cargo trams :wink:

That's a pretty epic leap for a bulldozer. :mrgreen:

What sprite error is there? Except maybe a bit too large separation of the single vehicle parts I don't see anything...

I love HEQS for mineral hauling from the 1950s onwards, but the earlier road-trains are all so slow at 24km/h. Were these really that slow?

Even slower in fact. Most bulldozers have a real-life speed of about 8km/h. I've multiplied that by 3 :P

I counted them on the wrong sprites :-) Thanks for putting my nose directly at it.

Thought I'd post an update on progress for the next release (0.7)....

- Industrial trams need load sprites and more wagon types, so I still have some drawing to do :P
- The bug reports in these forums are useful, and I would like to fix them, but it would be easy to miss some. If they are submitted to the project bug tracker that's very helpful. http://dev.openttdcoop.org/projects/heqs/issues (Registering once gives access to all the bug trackers for the other projects there - FIRS, FISH, 2CC Train Set, OpenGFX etc).

After 0.7 is done I have some plans for new vehicles (more trams) and more plans to improve some of the existing stuff (especially tractors). It would be handy to know what era vehicles are most wanted for....
- pre 1930?
- 1930-2000?
- post 2000?

cheers,

Andy

Hey, Andy!

I was just looking through the wiki newgrf specs on realistic acceleration. (I decided to try to make eGRVTS compatible with realistic RV acceleration.)

I presume that since HEQS predates realistic RV acceleration, all vehicles use the default settings. If I can manage to figure out how to add the correct lines of code to the eGRVTS NFO and get it working, would you like some help tweaking HEQS? Raising their TE would help these vehicles perform better than the stock or eGRVTS vehicles on steep hills, with heavy loads, etc. Let me know what you think.

HEQS was a test grf for realistic RV acceleration :)

I've tested most of the vehicles on long hills with the default 'steepness' setting. Terkhen also did quite a lot of testing as well. Some vehicles will perform well on hills, some will not :P
