First you need to declare the trailers when you create them. For example:

PHP код:


new TruckingTrailers[3];
TruckingTrailers[0] = CreateVehicle(/*vehicletype, Float:x, Float:y, Float:z, Float:rotation, color1, color2, respawn_delay, addsiren=0*/); //fruit trailer 


Then check to see what trailer is by using something like this:

PHP код:


if(GetVehicleTrailer(GetPlayerVehicleID(playerid)) == TruckingTrailers[0])
{
    //trailer is fruit trailer
} 


Use IsTrailerAttachedToVehicle to check if the vehicle has ANYTHING attached to it.

For example,

PHP код:


if(IsTrailerAttachedToVehicle(GetPlayerVehicleID(playerid)) != 1)
    return print("no trailer"); //obviously you can change what happens if there is no trailer attached.
