Articulated Road Vehicles
From OpenTTD
Articulated road vehicles are a NewGRF feature for OpenTTD that allows support of GRF files which use this feature. Articulated road vehicles allows support of sets containing, for example, trucks with trailers or multi-car trams.
[edit] GRF Sets
Many GRF sets now use this feature, notably: GRVTS - Includes articulated hopper, flatbed and tanker lorries and articulated trams.
[edit] Coding of articulated road vehicles
Road vehicles cannot be made articulated on demand by the player and must be coded in their articulated form via a variational action2 callback in the GRF file itself.
Articulated road vehicles do not behave in the same way as trains in distributing the action0 properties:
| Statistic | Rail | Road |
|---|---|---|
| Date of intro | Fro | Fro |
| Reliablity decay | Fro | Fro |
| Vehicle life | Fro | Fro |
| Model life | Fro | Fro |
| Climate | Fro | Fro |
| Load rate | Veh | Veh |
| Speed | WO | Fro |
| Running cost | Tot | Fro |
| Capacity | Tot | Tot |
| Cost | Tot | Fro |
| Sound effect | Fro | Fro |
| Power | Tot | NI |
| Weight | Tot | NI |
| Tractive effort | Tot | NI |
| Air drag | NI | NI |
| Refit cost | Tot | Tot |
| Retire early | Fro | Fro |
| Misc flags | DOF | Fro |
| Refittable | Veh | Veh |
- Max = takes the maximum value from the vehicles in the consist
- Min = takes the minimum value from the vehicles in the consist
- Ave = takes the average value from the vehicles in the consist
- Tot = takes the total value from the vehicles in the consist
- Fro = takes the value from the front vehicle in the consist
- Veh = vehicles behave according to their own value
- NI = not implemented in OpenTTD (yet)
- DOF = depends on flag; for train tilts it's Mat, for the others it's Veh.
- WO = Fro if wagon override enabled of front vehicle, Min if wagon override disabled
