pawn Код:

doorslocked[playerid]=1;

One problem lies there... You're locking the playerid not the vehicle ID.

You need to review your code more... There's no doubt simple mistakes such as this.

Also go back to using SetVehicleParamsForPlayer, and doing all the user IDs,

Then

pawn Код:

public OnVehicleStreamIn(vehicleid, forplayerid)
{
        if(doorslocked[vehicleid]==1)
        {
        SetVehicleParamsForPlayer(vehicleid,forplayerid,0,1);
        }
}
