[SOLVED][race] permanent vehicle handling problem

[Kubimate]

Hi! I have a problem making a script with custom vehicle handling for race gamemode. I made a script that uses setModelHandling (also tried setVehicleHandling) and onResourceStart. It works, but when a player dies and respawns, the handling of his vehicle restores back to default.

I don't know if I should somehow force the handling change to be permanent on resource start or if I should somehow make these changes apply everytime a player respawns?

One solution i think of was to make an invisible marker on every checkpoint, and make setVehicleHandling onMarkerHit (which i managed to succesfully write), but it feels like a dumb solution and i know it can be done more efficient by good scripting.

I tried using onClientPlayerSpawn, which is client side, and setVehicleHandling appears to be server side. I have no idea yet how to connect scripts like that, but I'm still learning.

My tuning on marker hit script:

  
function tuning(hitMarker, matchingDimension) 
    if (matchingDimension) then 
        local theVehicle = getPedOccupiedVehicle(source)   
        if theVehicle then 
        outputChatBox ("Tuned!") 
        setVehicleHandling(theVehicle, "engineAcceleration", 35.0) 
        end  
    end 
end 
addEvent("onPlayerMarkerHit", true)  
addEventHandler("onPlayerMarkerHit", getRootElement(), tuning) 
  

My handling test script:

  
function handlingChange ( ) 
    setVehicleHadling(504, "EngineAcceleration", 35.0) 
end 
addEventHandler ( "onPlayerSpawn", getLocalPlayer(), handlingChange ) 
  

TL;DR

How to keep starting handling changes after player respawn in a race gamemode?

I'm a scripting beginner, please be nice to me!

Any help will be appreciated!

Try to use:

Idea with markers it's not so good as for me. So, edit :race/race_server.lua

Find:

--      launchRace 
function unfreezePlayerWhenReady(player) 
    if not isValidPlayer(player) then 
        outputDebug( 'MISC', 'unfreezePlayerWhenReady: not isValidPlayer(player)' ) 
        return 
    end 
    if isPlayerNotReady(player) then 
        outputDebug( 'MISC', 'unfreezePlayerWhenReady: isPlayerNotReady(player) for ' .. tostring(getPlayerName(player)) ) 
        TimerManager.createTimerFor("map",player):setTimer( unfreezePlayerWhenReady, 500, 1, player ) 
    else 
        RaceMode.playerUnfreeze(player) 
        outputDebug( 'MISC', 'unfreezePlayerWhenReady: setElementFrozen false for ' .. tostring(getPlayerName(player)) ) 
    end 
end 

Under

RaceMode.playerUnfreeze(player) 

Add your code

        local theVehicle = getPedOccupiedVehicle(source)   
        if theVehicle then 
        outputChatBox ("Tuned!") 
        setVehicleHandling(theVehicle, "engineAcceleration", 35.0) 
        end  

If you want to do this only for you then do:

      if getPlayerSerial(player) == "twoj_serial" then 
 local theVehicle = getPedOccupiedVehicle(source)   
        if theVehicle then 
        outputChatBox ("Tuned!") 
        setVehicleHandling(theVehicle, "engineAcceleration", 35.0) 
        end  
end

Edited my post then.

I don't really want to edit server files, I just need a 'standalone' resource which would only be used in one race map, edited and used in another, eventually.

onPlayerSpawn 

Does not work, kinda...

I made this script:

function player_Spawn ( posX, posY, posZ, spawnRotation, theTeam, theSkin, theInterior, theDimension ) 
    outputChatBox("SPAWNED") 
    if isPedInVehicle (source) then 
    outputChatBox("IN CAR") 
    setModelHandling(504, "EngineAcceleration", 40) 
    end 
end 
addEventHandler ( "onPlayerSpawn", getRootElement(), player_Spawn ) 

When I start the race, I got 'SPAWNED' message and my handling is changed, but it don't says 'IN CAR' as if the player was not in a car. So... why is handling applied?

So, I tried removing isPedInVehicle check:

function player_Spawn ( posX, posY, posZ, spawnRotation, theTeam, theSkin, theInterior, theDimension ) 
    outputChatBox("SPAWNED") 
    --if isPedInVehicle (source) then 
    outputChatBox("IN CAR") 
    setModelHandling(504, "EngineAcceleration", 40) 
    --end 
end 
addEventHandler ( "onPlayerSpawn", getRootElement(), player_Spawn ) 

I got both messages and custom handling. Died, respawned, again both messages, but no handling.

Next i tried with onPlayerVehicleEnter

function enterVehicle  ( theVehicle, seat, jacked ) 
    outputChatBox("ENTERED") 
    if isPedInVehicle (source) then 
    outputChatBox("IN CAR") 
    setVehicleHandling(theVehicle, "EngineAcceleration", 40) 
    end 
end 
addEventHandler ( "onPlayerVehicleEnter", getRootElement(), enterVehicle  ) 

Result: same as script above - I got both messages and custom handling. Died, respawned, again both messages, but no handling.

So now the main question of this tread is going to be: what function is used by race gamemode to 'respawn' players in cars after they die, and what event should i listen to to execute handling change?

Alternatively, I think about to make my script change handling to every players' car every second, so when a player dies and respawns, after 1 second my handling would be back. (This feels like the marker-on-every-checkpoint-poor-idea one )

What does "setVehicleHandling" return?

outputChatBox(tostring(setVehicleHandling(theVehicle, "EngineAcceleration", 40)))

[Kubimate]

I restarted MTA, and none of scripts from my previous post actually apply handling changes... What do I have to do to reload my script when testing?

Anyway, as you asked,

function enterVehicle  ( theVehicle, seat, jacked ) 
    if isPedInVehicle (source) then 
    outputChatBox(tostring(setVehicleHandling(theVehicle, "EngineAcceleration", 40))) 
    end 
end 
addEventHandler ( "onPlayerVehicleEnter", getRootElement(), enterVehicle  ) 

returns false

[Bonsai]

The solution might be:

"engineAcceleration" instead of "EngineAcceleration"

e != E

[Kubimate]

Yes, you are right, it has to be lowercase e, now it works like a charm

Thank you all for help!

Final product:

function enterVehicle  ( theVehicle, seat, jacked ) 
    if isPedInVehicle (source) and getElementModel (theVehicle) == 478 then 
    setVehicleHandling(theVehicle, "mass", 1050.0) 
    setVehicleHandling(theVehicle, "turnMass", 2000.0)

    setVehicleHandling(theVehicle, "suspensionFrontRearBias", 0.55) 
    setVehicleHandling(theVehicle, "suspensionAntiDiveMultiplier", 0.3) 
    setVehicleHandling(theVehicle, "seatOffsetDistance", 0.25) 
    setVehicleHandling(theVehicle, "collisionDamageMultiplier", 0.70) 
    setVehicleHandling(theVehicle, "modelFlags", 0x40002804) 
    setVehicleHandling(theVehicle, "handlingFlags", 0x4000001) 
    setVehicleHandling(theVehicle, "headLight", long) 
    setVehicleHandling(theVehicle, "tailLight", small) 
    setVehicleHandling(theVehicle, "animGroup", 1) 
    --outputChatBox("Handling changed successfully !") 
    end 
end 
addEventHandler ( "onPlayerVehicleEnter", getRootElement(), enterVehicle  )
