Vehicle Health and Maintenance

archived

All vehicles has vehicle condition that has a range from 0% to 100%. Every brand new vehicle starts at 100%.
new vehicle starts at 100.
As you use them, their health declines with steady rate.
You are required to maintain the car at Car Mechanic or Car Dealership after every 2500 km amount of kilometres.
Every car will have a total lifetime distance of 20,000 km.
You can drive a car without maintaining it, but its health declines quicker (can make its rate increase the more appointments you miss).
After vehicle health hits 0.0%:
- Car breaks down and gets sent off to scrapyard (removed from player).

Scrapped these:

Certain factors cause the vehicle health to decline further:
- Hit metal or concrete objects.
- Hit other players.

Condition Range

Stored as condition_value (int): 0 = 100% (brand new), 100,000 = 0% (destroyed).
Display formula: 100 - (condition_value / 1000.0) → shows as percentage.

Degradation Rate

Base rate: 100,000 points over 25,000 km → 1 point per 250 meters
Service interval: every 2,500 km
Each properly-maintained 2,500 km costs ~10,000 points (10% condition)
Missed services increase the degradation rate (each missed appointment stacks further)

Servicing

Location: Car Mechanic only
Cost: €5,000 flat fee.
- In the case that a player has missed multiple appointments, the formula will be: (€5,000 * missed_appointments)
~~Restores:~~ ~~2.5%~~ ~~condition (2,500~~ ~~points off condition_value)~~
Resets: missed appointment counter back to 0
Updates the last_service_distance on the vehicle

Car Breakdown (0% condition)

New DB Columns Needed on VehicleRegistration.

Column	Data Type	Purpose
condition_value	int	Already added, needs migration
missed_services	int	Tracks skipped `2,500 km` checkpoints
last_service_distance	double	Odometer at last service

Still Open

- DB record on scrap: hard delete or keep with a scrapped flag?

- Warning at low condition (e.g. 10%)? Not discussed yet
