🎢 CostInflator plugin for OpenRCT2
CostInflator is a plug-in for OpenRCT2 that allows you to increase (or decrease) the cost of various expenses, such as staff wages or ride upkeep.
Table of contents
The purpose of the CostInflator plugin is to enable a player of OpenRCT2 to dynamically change the balance of the financial aspect of the Rollercoaster Tycoon by adjusting the cost of various expenses.
The initial release of CostInflator can be used to adjust Ride and Stall/Facility running costs (upkeep) separately, each of which can be increased (or decreased) by specifying a multiplier in the settings window (shown above). When the game calculates the running costs for these cost categories, the plugin multiplies the result by the corresponding Multiplier setting. For example, a Ride Running Costs Multiplier of
2.00 will double the running costs for all rides, while a multiplier of
0.50 will half it. Multiplier settings can range from
0.00 (for no costs) up to
In addition to the Multiplier setting, the Inflation setting determines the 'inflation rate' of the corresponding multiplier: At the start of each month, the value of the Inflation setting is added to the multiplier. For example, a Ride Running Costs Inflation of '0.10' will increase the Ride Running Cost Multiplier by 0.1 at the start of every month. Inflation settings can range from
The initial release of CostInflator supports the following categories:
- Ride running costs (upkeep)
- Stall/facility running costs (upkeep)
More will be added in future releases.

How it works
The plugin subscribes to the
'ride.ratings.calculate' API hook, which the OpenRCT2 game engine invokes each time the running cost of a ride, stall or facility is calculated. The ride object is retrieved by ID via the
map.getRide plugin API method and the
runningCost property is adjusted according to the multiplier.
The plugin also subscribes to the
'interval.day' API hook, which the OpenRCT2 game engine invokes once per day in-game time. If
date.monthProgress is zero (meaning the month has just begun), the plugin updates the Multiplier setting for each cost category, according to the corresponding Inflation setting.
Whenever settings are changed, they are stored in the park file (via
parkStorage API object).
