Hello.

Since i saw the great features of the new sa-mp 0.3z RC update i was thinking about detecting wheels and the petrol cap from all vehicles.
Whats new?
This include will add a new callback and new natives:

pawn Code:

#define BULLET_HIT_PETROL_TANK 0
#define BULLET_HIT_LEFT_FRONT_WHEEL 1
#define BULLET_HIT_RIGHT_FRONT_WHEEL 2
#define BULLET_HIT_LEFT_BACK_WHEEL 3
#define BULLET_HIT_RIGHT_BACK_WHEEL 4
#define BULLET_HIT_BODY 5

//GetVehicleTireStatus
#define VEHICLE_RIGHT_BACK_WHEEL 0
#define VEHICLE_RIGHT_FRONT_WHEEL 1
#define VEHICLE_LEFT_BACK_WHEEL 2
#define VEHICLE_LEFT_FRONT_WHEEL 3
//Callbacks
forward OnPlayerShootVehiclePart(playerid, weaponid, vehicleid,hittype);

//Natives
native EnableVehicleDamage(true/false); //Add this under OnGamemodeInit/OnFilterscriptInit to enable/disable.
native EnableVehiclePetrolCapExplosion(true/false);//Add this under OnGamemodeInit/OnFilterscriptInit to enable/disable.
native EnableVehicleWheelTirePop(true/false);//Add this under OnGamemodeInit/OnFilterscriptInit to enable/disable.
native ToggleVehicleDamage();//Toggle Vehicle Damage
native ToggleVehiclePetrolCapExplosion();//Toggle Vehicle Petrol Cap Explosion
native ToggleVehicleWheelTirePop();//Toggle Vehicle Wheel Tire Pop
native GetVehicleTireStatus(Vehicleid,Tire);//Checking the Vehicle Tire Status (Return 1 : Tire Popped - Return 0 : Tire Unpopped)

How to use?
1. Download the a_vshot.zip and extract it in the sa-mp folder.
2. Add #include <a_vshot.inc> on the top of your script
3. Add public OnPlayerShootVehiclePart(playerid, weaponid, vehicleid,hittype) in your script.

Example
This is an example how you can use this callback.
Example 1

pawn Code:

public OnPlayerShootVehiclePart(playerid, weaponid, vehicleid,hittype)
{
    if(hittype==BULLET_HIT_PETROL_TANK)//When player shoots on the petrol cap of a vehicle
    {
        new Float:vPosx,Float:vPosy,Float:vPosz;
        GetVehiclePos(vehicleid, vPosx,vPosy,vPosz);
        CreateExplosion(vPosx,vPosy,vPosz, 6, 30.0);
        SetVehicleToRespawn(vehicleid);
        SendClientMessage(playerid,-1,"You have hit the PETROL CAP!");
        return 1;
    }
    if(hittype==BULLET_HIT_LEFT_FRONT_WHEEL)//When player shoots on the left front wheel of a vehicle
    {
        if(GetVehicleTireStatus(vehicleid,VEHICLE_LEFT_FRONT_WHEEL)==0)
        {
            SetVehicleTireStatus(vehicleid,VEHICLE_LEFT_FRONT_WHEEL);//will pop the left front wheel tire
            SendClientMessage(playerid,-1,"You have hit the LEFT FRONT WHEEL!");
            return 1;
        }
        else SendClientMessage(playerid,-1,"The LEFT FRONT WHEEL TIRE is already popped!");
    }
    if(hittype==BULLET_HIT_RIGHT_FRONT_WHEEL)//When player shoots on the right front wheel of a vehicle
    {
        if(GetVehicleTireStatus(vehicleid,VEHICLE_RIGHT_FRONT_WHEEL)==0)
        {
            SetVehicleTireStatus(vehicleid,VEHICLE_RIGHT_FRONT_WHEEL);//will pop the right front wheel tire
            SendClientMessage(playerid,-1,"You have hit the RIGHT FRONT WHEEL!");
            return 1;
        }
        else SendClientMessage(playerid,-1,"The RIGHT FRONT WHEEL TIRE is already popped!");
    }
    if(hittype==BULLET_HIT_LEFT_BACK_WHEEL)//When player shoots on the left back wheel of a vehicle
    {
        if(GetVehicleTireStatus(vehicleid,VEHICLE_LEFT_BACK_WHEEL)==0)
        {
            SetVehicleTireStatus(vehicleid,VEHICLE_LEFT_BACK_WHEEL);//will pop the left back wheel tire
            SendClientMessage(playerid,-1,"You have hit the LEFT BACK WHEEL!");
            return 1;
        }
        else SendClientMessage(playerid,-1,"The LEFT BACK WHEEL TIRE is already popped!");
    }
    if(hittype==BULLET_HIT_RIGHT_BACK_WHEEL)//When player shoots on the right back wheel of a vehicle
    {
        if(GetVehicleTireStatus(vehicleid,VEHICLE_RIGHT_BACK_WHEEL)==0)
        {
            SetVehicleTireStatus(vehicleid,VEHICLE_RIGHT_BACK_WHEEL);//will pop the right back wheel tire
            SendClientMessage(playerid,-1,"You have hit the RIGHT BACK WHEEL!");
            return 1;
        }
        else SendClientMessage(playerid,-1,"The RIGHT BACK WHEEL TIRE is already popped!");
    }
    if(hittype==BULLET_HIT_BODY)//When player shoots on a vehicle
    {
        SendClientMessage(playerid,-1,"You have hit the VEHICLE!");
        return 1;
    }
    return 1;
}
