Script AI Manager scriptable?

Hello everyone,
I have a question about the Script AI Manager, in itself it is possible to display the trips via the GUI. Is it also possible to record the trips via script (except the BeamNGNodeStreamPhysFS class)?

So, record the trip for a vehicle, call the saved file via script and let it play for another vehicle and also drive behind it?
Thanks in advance

 

Heyo, the AI extension for vehicles exposes the recording functionality. In vehicle Lua, you can do this, for example:

Code:

ai.startRecording()
-- Drive around for some time to actually record a script
-- When finished, stop the recording. The function returns the recorded script
rec = ai.stopRecording()
ai.startFollowing(rec)

In game engine Lua things get a bit trickier because you need to transfer the recording from the vehicle's Lua VM to the game engine's. You can do this via command queueing:

Code:

local M = {}

M.startRecording = function()
  local veh = be:getPlayerVehicle(0) -- or whichever you want
  veh:queueLuaCommand('ai.startRecording()')
end

M.stopRecording = function()
  local veh = be:getPlayerVehicle(0) -- or whichever you want
  local cmd = 'obj:queueGameEngineLua("extensions.hook(\\"onVehicleSubmitRecording\\","..tostring(objectId)..","..serialize(ai.stopRecording())..")")'
  veh:queueLuaCommand(cmd)
end

M.onVehicleSubmitRecording = function(vehId, data)
  local veh = be:getPlayerVehicle(0) -- or whichever you want
  if veh:getID() == vehId then
    veh:queueLuaCommand('ai.startFollowing(' .. serialize(data) .. ')')
  end
end

return M

This is a small sample extension that would allow you to control the scriptAI from game engine Lua. The key line here is the cmd in stopRecording; it makes the vehicle queue a command in game engine Lua which calls onVehicleSubmitRecording on all extensions with the recording obtained from ai.stopRecording(). This way you get the script from vehicle Lua to game engine Lua.
