Up-to-date Lua tutorials?

[WallMart]

Hi guys.

Back after a long time of in-activity on MTA, i decided i wanted to learn to script in Lua.

However the tutorials i found are a bit outdated, since the scripts ( i literally copied them, just to try it out ) don't work anymore.

If anyone could link me to any tutorial on lua that works with the current MTA, that would be nice.

Greets, WallMart

EDIT: i figured i should post the code too, maybe i did something horribly wrong.

local spawnX, spawnY, spawnZ = 1959.55, -1714.46, 10 
function joinHandler() 
    spawnPlayer(source, spawnX, spawnY, spawnZ) 
    fadeCamera(source, true) 
    setCameraTarget(source, source) 
    outputChatBox("Welcome to My Server", source) 
end 
addEventHandler("onPlayerJoin", getRootElement(), joinHandler)

function spawn(player) 
   if getElementType(player)=="player" then 
      local desiredSkin = getElementData(player, "skinID") 
      if desiredSkin then 
         skinID=desiredSkin 
      else 
         skinID= math.random(9,288) 
      end 
      spawnX = math.random(-691, -671) 
      spawnY = math.random(962, 971) 
      spawnZ = 20 
      repeat 
      until 
      spawnPlayer ( player, spawnX, spawnY, spawnZ, 180, skinID ) 
  
      fadeCamera(player, true) 
      setCameraTarget(player, player) 
   end 
end 
  
addEventHandler("onPlayerJoin", root, 
   function() 
      setTimer(function(src) 
         spawn(src) 
      end, 5000, 1, source) 
   end 
) 
  
addEventHandler("onPlayerWasted", root, 
   function() 
      if getElementType(source)=="player" then 
         local tmpID = getPedSkin(source) 
         --outputChatBox(tmpID.."f") 
         setElementData(source,"skinID",tmpID) 
         setTimer(spawn, 5000, 1, source) 
      end 
   end 
)

This is a server side code, do you have that in meta.xml? Like :

  
<meta> 
         <script src="s_name.lua" type="server"/> 
</meta>

it still says that it contains illegal characters.

but as i said, i took this literally from an official tutorial of the mta wiki and it stated that it should work with those lines of code.

so if you an updated tutorial i would be grateful

what use has the line 12 and 13?

^^

spawnZ = 20

repeat --this

until --n dat

spawnPlayer ( player, spawnX, spawnY, spawnZ, 180, skinID )

^^

[WallMart]

okay guys, it works now as it should! but still i'd like to see some tutorials. so if anyone knows about them, send em over!

[pa3ck]

BTW I think wiki is always up-to-date.

function spawn(player) 
   if getElementType(player)=="player" then 
      local desiredSkin = getElementData(player, "skinID") 
      if desiredSkin then 
         skinID=desiredSkin 
      else 
         skinID= math.random(9,288) 
      end 
      spawnX = math.random(-691, -671) 
      spawnY = math.random(962, 971) 
      spawnZ = 20 
      repeat 
      until 
      spawnPlayer ( player, spawnX, spawnY, spawnZ, 180, skinID ) 
  
      fadeCamera(player, true) 
      setCameraTarget(player, player) 
   end 
end 
  
addEventHandler("onPlayerJoin", root, 
   function() 
      setTimer(function(src) 
         spawn(src) 
      end, 5000, 1, source) 
   end 
) 
  
addEventHandler("onPlayerWasted", root, 
   function() 
      if getElementType(source)=="player" then 
         local tmpID = getPedSkin(source) 
         --outputChatBox(tmpID.."f") 
         setElementData(source,"skinID",tmpID) 
         setTimer(spawn, 5000, 1, source) 
      end 
   end 
) 

Use of element data here is quite bad, passing the skin id as function argument thru timer would be much better.

also, while i'm at it anyway. how do i call current vehicle?

would that be currentVehicle or playerVehicle or something? sorry for the noobish questions but just started out

[pa3ck]

getPedOccupiedVehicle(getLocalPlayer()) 

[WallMart]

okay, can someone help me with this script? it's the first one i have written myself, obviously it doesnt work

i wanted to make a script, that when players press the R key their car will be completely repaired.

function playerPressedKey (r, press) 
    local theVehicle = getPedOccupiedVehicle ( thePlayer ) 
    if (press) then 
    setElementHealth (theVehicle, getElementHealth(theVehicle) + 100) 
    end 
end 
addEventHandler ("setElementHealth", root, getPedOccupiedVehicle) 

it's nice if anyone could fix the code, it would be even better with explanation ( and tell me if i really fucked up, i just want to learn )

[csiguusz]

Your code doesn't make much sense . Try this, on client side. And if you need further explaination then ask just ask for it!

function repairCar ()    
    local vehicle = getPedOccupiedVehicle ( localPlayer ) 
    if vehicle then -- check if the local player is in a vehicle 
        fixVehicle ( vehicle ) -- fix it 
    end 
end 
  
bindKey ( "r", "down", repairCar ) -- bind a key to a function
