Re: error 021: symbol already defined: "vehicleid" - iggy1 - 18.07.2013

You need to learn about variable scope.

https://sampwiki.blast.hk/wiki/Scripting_Basics#Scope

You can't have 2 (or more) variables in the same scope, that have the same name.

pawn Код:

new vehicleid = GetPlayerVehicleID(playerid);//first definition
    if(newstate == PLAYER_STATE_DRIVER && oldstate == PLAYER_STATE_ONFOOT)
    {
    if(vehicleid ==dcar1)
    {
    if(strcmp(PlayerName(playerid), "Avto_Kushta", true) != 0)
    {
   //...
        }
       }
    }
    new vehicleid = GetPlayerVehicleID(playerid);//<<Symbol already defined above

You should also learn to indent your code properly.

Works, thanks bro

Re: error 021: symbol already defined: "vehicleid" - Elie1996 - 18.07.2013

Alright, I know what he did works, because all he's done is actualy remove the line "new vehicleid"
but you've got to be careful: it might affect vehicleid that was defined earlier, if you want to get the new vehicle ID and not ruin what vehicleid was before, then just define a new variable like this:

pawn Код:

new vehicleid2;
