Racing position in race scenario?

Hi, currently here's the wip "Racing Position" app that shows a blank area when used in a race scenario.



That feature is from way back pre-race update and on hold I suppose? In the meantime, is there a simple way with lua to create some kind of UI element that shows the current position in a race scenario that we could use until the official app is updated? Maybe someone has dabbled in this area and likes to share something that's helpful for anyone creating race scenarios.

Btw, Wreckfest has a pretty cool approach with the position and deltas to the opponent in front, as well as behind the player. So far I only use a basic lua, copied from the official derby race scenario with Gamergulls ScriptAI lua code to load AI lines.

Heres the lua so far:

Code:

local M = {}

local helper = require('scenario/scenariohelper')
local logTag = 'hirochiF8races58'

local finalWaypointName = 'derby_wp14'
local finalTriggerName = 'trigger_finish1'
local playerInstance = 'scenario_player0'
local aiInstance1 = 'scenario_opponent1'
local aiInstance2 = 'scenario_opponent2'
local aiInstance3 = 'scenario_opponent3'
local aiInstance4 = 'scenario_opponent4'
local aiInstance5 = 'scenario_opponent5'

local running = false
local playerWon = false
local aiFinished = false
local noOfLaps = 8
local lapsCompleted = {}

local function reset()
  lapsCompleted['scenario_player0'] = 0
  lapsCompleted['scenario_opponent1'] = 0
  lapsCompleted['scenario_opponent2'] = 0
  lapsCompleted['scenario_opponent3'] = 0
  lapsCompleted['scenario_opponent4'] = 0
  lapsCompleted['scenario_opponent5'] = 0
 
  running = false
  playerWon = false
  aiWon = false
end

local function fail(reason)
  scenario_scenarios.finish({failed = reason})
  reset()
end

local function success(reason)
  scenario_scenarios.finish({msg = reason})
  reset()
end

local racers = {"scenario_opponent1", "scenario_opponent2", "scenario_opponent3", "scenario_opponent4", "scenario_opponent5"}
local filenames = {"f8mc-1sunburstofforad", "f8mc-2pickupmarauder", "f8mc-3etki300m", "f8mc-4legranluxev6", "f8mc-5fullsizedriftmissile"}

local function onRaceStart()

  scenario_scenarios.trackVehicleMovementAfterDamage(playerInstance, {waitTimerLimit=10})

  running = true
end

local function onCountdownStarted()
  reset()
 
  local recordings = {}
    for i, v in ipairs(racers) do
        local id = scenetree.findObject(racers[i]):getId()
        local filename = "/replays/scriptai/tracks/"..filenames[i]..".track.json"
        local scriptData = jsonReadFile(filename)
        --dump(scriptData)
        recordings[id] = scriptData.recording
        scenetree.findObject(racers[i]):queueLuaCommand("ai.startFollowing("..serialize(recordings[id])..")")
    end
end

local function onRaceWaypointReached(data)
  --log('I', logTag,'onRaceWaypointReached called ')
  if data.waypointName == finalWaypointName then
    lapsCompleted[data.vehicleName] = lapsCompleted[data.vehicleName] + 1
    if lapsCompleted[data.vehicleName] == noOfLaps then
      if data.vehicleName == playerInstance and not aiFinished then
        playerWon = true
    end
    end
  end
end

local function onRaceResult()
  if playerWon then
    success('scenarios.west_coast_usa.derby_asphalt.win.msg')
  else
    fail('scenarios.west_coast_usa.derby_asphalt.fail.msg')
  end
end

local function onBeamNGTrigger(data)

  if data.triggerName == finalTriggerName and data.event == 'enter' then
    if data.subjectName == aiInstance1 or data.subjectName == aiInstance2 or data.subjectName == aiInstance3 or data.subjectName == aiInstance4 or data.subjectName == aiInstance5 then

      lapsCompleted[data.subjectName] = lapsCompleted[data.subjectName] + 1
      if lapsCompleted[data.subjectName] == noOfLaps then
        aiFinished = true
      end
    end
  end
end

M.onRaceStart = onRaceStart
M.onCountdownStarted = onCountdownStarted
M.onRaceWaypointReached = onRaceWaypointReached
M.onRaceResult = onRaceResult
return M
