DynamicResourcePrices

DynamicResourcePrices

DynamicResourcePrices transforms the static economy of Derail Valley into a living market system where resource prices evolve continuously based on time, randomness, and player behavior.

Core Concept:

Instead of fixed prices, Fuel, Coal, and Power are now governed by a dynamic economy model driven by:

• []Daily market trends

  []Interval-based updates

  []Random volatility

  []Player job performance (cargo condition)

  []Time-limited economic events

• []Each resource has a base price and evolves over time.

  []Prices are updated multiple times per in-game day (configurable).

  []Influences per update:

  []Trend (global direction)

  []Random fluctuation

  []Active event impact

• []Every in-game day generates a new trend per resource.

  []Trends define whether prices generally:

  []Rise 📈

  []Fall 📉

→ Simulates long-term market behavior.

3. Interval-Based Updates

• []A day is split into configurable update intervals (e.g. 4–24).

  []Each interval applies partial price changes.

4. Job-Based Market Events

• []Completing jobs creates market events based on cargo condition:

• []Reduces prices (reward effect)

• []Increases prices (penalty effect)

  []Effects are:

  []Aggregated per job (all wagons)

  []Scaled per wagon condition

  []Clamped to configurable limits

• []Each job creates a temporary market event:

  []Has a defined lifetime (in days)

  []Can be fixed or randomized

  []Multiple events can stack and overlap.

  Important behavior:

  • []When all events for a resource expire:

    []Price resets to its pre-event baseline

  → Prevents permanent inflation or deflation.

  6. PitStop Integration

  • []Prices are dynamically applied to:

    []Coal

    []Electric charge

  []PitStop UI updates automatically and safely:
