STAY TUNED FOR A NEW (and a better...) JOANNET LIBRARY!

This library is NOT compatible with MTR 4, only MTR 3.

Built-in Features

fetch(url: String)

⚠️ Internal use only. Do not use.
Performs a GET request using the provided URL.

function fetch(url) { return response }

---

fetchDepartures(stationID: String, url: String, port: Number, secure: Boolean)

Requires fetch() to be imported.
Retrieves the next departures from a station using its code. Optional parameters allow you to set a custom base URL, port, and HTTPS mode. If all three are null, it defaults to:
http://localhost:8888/arrivals?stationId=<stationID>

function fetchDepartures(stationID, url, port, secure) { return Array<Object> }

---

fetchDeparturesFromPlatform(stationID: String, platformID: String, url: String, port: Number, secure: Boolean)

Requires fetch() to be imported.
Gets the next departures from a specific platform of a station. URL, port, and HTTPS are optional. Defaults to:
http://localhost:8888/arrivals?stationId=<stationID>

function fetchDeparturesFromPlatform(stationID, platformID, url, port, secure) { return Array<Object> }

---

fetchFirstDepartureFromPlatform(stationID: String, platformID: String, url: String, port: Number, secure: Boolean)

Requires fetch() to be imported.
Returns only the first upcoming departure for a specific platform. Same URL behavior as above.

function fetchFirstDepartureFromPlatform(stationID, platformID, url, port, secure) { return Object }

---

fetchMTRData(url: String, port: Number, secure: Boolean)

Requires fetch() to be imported.
Fetches all MTR data and combines the dimensions into one object. Optional base URL, port, and HTTPS settings apply. Defaults to:
http://localhost:8888/data

function fetchMTRData(url, port, secure) { return Object }

---

formatStop(stationName: String)

Formats a station name by trimming whitespace, removing emojis, and replacing single pipe characters.
If the name has multiple parts, extra names are grouped in parentheses.

• Example 1: "East Hills||Pittsburgh|East" → "East Hills (Pittsburgh/East)"
• Example 2: "West Ham 🍖||Stewie||South 🧭" → "West Ham (Stewie, South)"

function formatStop(stationName) { return String }

---

getCurrentFormattedTime()

⚠️ DEPRECATED: Use getTime(ms) instead.

Returns the current time as "HH:MM".

function getCurrentFormattedTime() { return String }

---

getCurrentStation(dataset: Object, stationID: String)

⚠️ DEPRECATED: Dataset functions will be removed in future versions.

Returns the station data for a given station ID from the provided dataset.
Fails if the station is not found or if stationID is not a string.

function getCurrentStation(dataset, stationID) { return Object }

---

getRemainingMinutes(arrivalTime: Number)

Returns the number of minutes remaining until the given arrival time.
Returns 0 if there's an error or if arrival is in less than 1 minute.
Fails if arrivalTime is undefined or not a number.

function getRemainingMinutes(arrivalTime) { return Number }

---

getStationData(xPos: Number, zPos: Number, url: String, port: Number, secure: Boolean)

Requires fetchMTRData() to be imported.
Returns the closest station to the given coordinates. URL, port, and HTTPS are optional. Defaults to:
http://localhost:8888/data

⚠️ Important: The MTR API won't list a station unless a route serves it. Place this script only after service has started.

function getStationData(xPos, zPos, url, port, secure) { return Object }

---

getStationsOfRouteFrom(dataset: Object, routeName: String, stationName: String)

⚠️ DEPRECATED: Dataset functions will be removed in future versions.

Returns a list of the remaining stations on a route from a given station.
Route and station names must match exactly with those in the MTR API.

function getStationsOfRouteFrom(dataset, routeName, stationName) { return Array<String> }

---

getTime(ms: Number?)

Returns the time in "HH:MM" format.
If ms is null, returns the current system time.

• getTime(1750843821742) → "11:30"
• getTime(null) → "09:35" (e.g. if run on June 25, 2025 at 09:35:14)

function getTime(ms) { return String }

---

Troubleshooting

Q: The scripts run slowly or produce errors on some models.
A: Low-spec computers may struggle with multiple script models. Try reducing the number of active models in the render area or lower their refresh rate.
More info: https://wiki.minecrafttransitrailway.com/mtr_addon:nte:js:eyecandy

---

Q: The model doesn't appear in the resource pack.
A: Reload the resource packs in-game using F3 + T.

---

Q: getStationData() does not return the nearest station.
A: Has the station already been assigned to a route and started service?
The MTR API won't recognize it until active service is detected.
