MLFeed: Race Data

This plugin provides other plugins with data about the current race. You might need to install it to make other plugins work.

Requires MLHook (you need to install that plugin too)

Please report performance issues! See bottom of page for who/where.

For Developers

Currently exposed data:

  • Sorted Player data
    • For each player: LatestCPTime, CPCount, Cached Previous CP Times, Spawn Status, Best Time, Best CP Times, Best Lap Times, Time Lost to Respawns (in total and per CP), NbRespawns
    • Sort methods
      • TimeAttack: sort by best time
      • Race: sorted by race leader
      • Race_Respawns: sorted by race leader, but updates ranking immediately when a player respawns to account for time-loss
  • Knockout data (for COTD / KO)
    • Per-Player Alive and DNF status
    • Total Rounds, Current Round, Alive Players, Number of KOs This Round, Next KO Milestone, Number of Players (originally)
  • The last record set by the current player
  • Ghost Data
    • Which ghosts have been loaded, the name of the ghost, and the ghost's checkpoint times.

Additional data exposure available upon request.

Using MLFeed: Race Data

Some plugins already using MLFeed:

Importing to your plugin

Include this in your info.toml file:

dependencies = ["MLHook", "MLFeedRaceData"] # need both

Usage: Getting started

Note: it is recommended that you use the Openplanet VSCode extension which will provide autocompletion and documentation for you when using MLFeed.

Main Entry Points

Several feeds are available that provide different information. The functions that provide the feeds are:

  • auto RaceData = MLFeed::GetRaceData_V2()
  • auto KoData = MLFeed::GetKoData()
  • auto GhostData = MLFeed::GetGhostData()

Full docs are below.

Upgrading to v0.4

See the upgrade guide:

Race Data Example

Main type: HookRaceStatsEventsBase_V2

Example usage: doing something on player respawn.

uint lastRespawnCount = 0;

void Update(float dt) {
    if (GetApp().CurrentPlayground is null) return;
    // Get race data and the local player
    auto RaceData = MLFeed::GetRaceData_V2();
    auto player = RaceData.GetPlayer_V2(MLFeed::LocalPlayersName);
    if (player is null) return;
    // check for respawns
    if (player.NbRespawnsRequested != lastRespawnCount) {
        lastRespawnCount = player.NbRespawnsRequested;
        if (lastRespawnCount != 0) {

void OnPlayerRespawn() {
    // do stuff

MLFeed:: Docs

The main exposed functions will get you the feeds.

Those then give you access data to each player/ghost.

Functions, properties, and types are exposed under the MLFeed:: namespace.


GetGhostData -- const SharedGhostDataHook_V2@ GetGhostData()

Object exposing GhostInfos for each loaded ghost. This includes record ghosts loaded through the UI, and personal best ghosts. When a ghost is unloaded from a map, its info is not removed (it remains cached). Therefore, duplicate ghost infos may be recorded (though measures are taken to prevent this). The list is cleared on map change.

GetKoData -- const KoDataProxy@ GetKoData()

Your plugin's KoDataProxy@ that exposes KO round information, and each player's spawn info, and lists of players for each sorting method. You can call this function as often as you like -- it will always return the same proxy instance based on plugin ID.

GetRaceData_V2 -- const HookRaceStatsEventsBase_V2@ GetRaceData_V2()

GetRaceData_V3 -- const HookRaceStatsEventsBase_V3@ GetRaceData_V3()

Exposes checkpoint data, spawn info, and lists of players for each sorting method. You can call this function as often as you like. Backwards compatible with RaceDataProxy (except that it's a different type; properties/methods are the same, though.)


GameTime -- uint GameTime

The current server's GameTime, or 0 if not in a server

LocalPlayersName -- const string LocalPlayersName

returns the name of the local player, or an empty string if this is not yet known

MLFeed::HookRaceStatsEventsBase_V3 (class)

The main class used to access race data. It exposes 3 sorted lists of players, and general information about the map/race.


GetPlayer_V2 -- const PlayerCpInfo_V2@ GetPlayer_V2(const string &in name) const

GetPlayer_V3 -- const PlayerCpInfo_V3@ GetPlayer_V3(const string &in name) const

Get a player's info


CPCount -- uint CPCount

The number of checkpoints each lap. Linked checkpoints are counted as 1 checkpoint, and goal waypoints are not counted.

CPsToFinish -- uint CPsToFinish

The number of waypoints a player needs to hit to finish the race. In single lap races, this is 1 more than .CPCount.

CpCount -- uint CpCount

The number of checkpoints each lap. Linked checkpoints are counted as 1 checkpoint, and goal waypoints are not counted.

LapCount -- uint LapCount

The number of laps for this map.

LastRecordTime -- int LastRecordTime

When the player sets a new personal best, this is set to that time. Reset to -1 at the start of each map. Usage: if (lastRecordTime != RaceData.LastRecordTime) OnNewRecord();

Map -- const string Map

The map UID

SortedPlayers_Race -- const array<PlayerCpInfo_V2>@ SortedPlayers_Race

An array of PlayerCpInfo_V2s sorted by most checkpoints to fewest.

Note: cast to PlayerCpInfo_V3 to access BestLapTimes.

SortedPlayers_Race_Respawns -- const array<PlayerCpInfo_V2>@ SortedPlayers_Race_Respawns

An array of PlayerCpInfo_V2s sorted by most checkpoints to fewest, accounting for player respawns.

Note: cast to PlayerCpInfo_V3 to access BestLapTimes.

SortedPlayers_TimeAttack -- const array<PlayerCpInfo_V2>@ SortedPlayers_TimeAttack

An array of PlayerCpInfo_V2s sorted by best time to worst time.

Note: cast to PlayerCpInfo_V3 to access BestLapTimes.

SpawnCounter -- uint SpawnCounter

This increments by 1 each frame a player spawns. When players spawn simultaneously, their PlayerCpInfo.spawnIndex values are the same. This is useful for some sorting methods. This value is set to 0 on plugin load and never reset.

MLFeed::PlayerCpInfo_V3 (class)

Each's players status in the race, with a focus on CP related info.
