my First Script help....

[Mr.Solo]

so hai..well i made my first script that detatch Truck Trailer if you press "o" . but after i asked and tried all , i gave up..because bindkey dosn't seems to work with function.. help me!! this is script i used for server side.

  
function unhookTrailer(source, commandName) 
   if (source and isPedInVehicle(source)) then 
      local theVehicle = getPedOccupiedVehicle(source) 
      local success = detachTrailerFromVehicle(theVehicle) 
      if (success) then 
         outputChatBox("Trailer detached!", source) 
      else 
         outputConsole("Trailer not attatched.", source) 
      end 
   end 
end 
addCommandHandler("unhook", unhookTrailer) 
bindkey( source, "o", "up", unhookTrailer)

bindkey( source, "o", "up", unhookTrailer)

What is the source there?

If its outside of any function, it won't work like that.

You could loop through all players and just bind the key for each of them.

Also you should probably rather name the first parameter of the unhookTrailer function "player" instead of "source",

since "source" is predefined when working with events.

[Mr.Solo]

so are you saying i need to put it in it's own function? well idk how , btw i tried make it in Client script with triggerServerEvent but failed..

try that

both command and bindkey dosn't work , it's hopeless nvm bro, i will try make other things

[Dimos7]

use /debugscript 3 and see if there is any erors

[tosfera]

You guys are all forgetting a single thing.. if you detach a trailer, it'll get attached right away again due to the position of the trailer and the truck.

@OP: try to use setElementPosition on the trailer when it gets detached to move it away from the truck to avoid it being attached again. Also, try to avoid isPedInVehicle since it fails quite often, a more reliable approach would be getPedOccupiedVehicle. also make sure that this script is on the server's side, not a client sided file.

ur legend thanks man , btw i do setelementPos x , y - 2 ,z or what??

[Dimos7]

y is the high so no x maybe change

[Chris!i!]

Use getElementPosition

Then

Add + 5 to x and y.

[Bonsai]

If you throw scripts at people instead of advices, they should better be working.

          if getElementType("trailer") then 
             setElementPosition(trailer, x+2, y, z)
