Yes but more work than:
- checkout the HEQS repo (GPL license)
- add the roadtypes table, and set the roadtype for each vehicle
- update the changelog

Then either
- ask me for access to push to the repo
- commit and push
- get it released on the coop account on bananas

Or
- commit and push to new repo (forked)
- release on own bananas account

Then most likely one doesn't get the vehicles that need HAUL.

There is a thing about fallback types, but I don't understand it to be honest

A solution of course would be that HEQS in its current form remains available while mods are identified as such and are given a unique GRF iD (HEQS_Haul ?)

I'm sure that would be technically possible, but seeing as HEQs (and many other sets) are written in NFO from years before NRT was even conceived, writing such a grf would probably be more difficult than either rewriting the original grf in NML, or just figuring out what bits need to be added to set road types in NFO and pasting those into the code.

I also thought about rewriting egrvts for NRT, but ultimately decided that someday Zephyris would get around to it, and in the meantime it would be faster to make OGFX++RVs for NRT. That got way out of hand with scope creep etc leading to a grf that still has no good name.

supermop wrote:I'm with Andy on this one - same as with metro trains, you need a metro type track to use them in game, or a parameter to make them run on electric rail. The grf can't change the active code for each vehicle based on what types it does or doesn't find. If one really wants to use RVs that someone has encoded as being HAUL type on regular ROAD, then could use a roadtype grf that sets ROAD as being compatible with HAUL.

railtypetable {
	RAIL,
	ELRL,
	NARROW_NON: [NAAN, RAIL],
	NARROW_3RD: [NAA3, RAIL],
	NARROW_OVER: [NABE, NAAE, ELRL],
	STANDARD_NON: [SAAN, RAIL],
	STANDARD_3RD: [SAB3, SAA3, RAIL],
	STANDARD_OVER: [SAAE, ELRL],
}

roadtypetable {
	ROAD,
	HEAVY_ROAD: [HAUL, ROAD],
}

• Not being to be able to build a roadtype without any compatible vehicle to purchase: the dropdown choice should be greyed out (as it happens with railtypes)
• Must be able to build a roadtype expired (no available vehicles to purchase) if you still have running vehicles compatible with it
• Tramtypes should work in the editor now, must check the conversion in game
• Multiplayer
• AIs, some of them seem to not work

• I cannot change back from a road with catenary to a road without.
• I am still able to convert a town owned road to HAUL by first converting to a road-type which supports both ROAD and HAUL
