You could try this:

pawn Код:

#define HOLDING(%0) \
    ((newkeys & (%0)) == (%0))
    
public OnPlayerKeyStateChange(playerid, newkeys, oldkeys) {
    if(HOLDING(KEY_FIRE) && GetVehicleModel(GetPlayerVehicleID(playerid)) == 407) {
        new
            Float: fAimingCoords[3];
            
        GetPlayerCameraPos(playerid, fAimingCoords[0], fAimingCoords[1], fAimingCoords[2]);
        /* the player is aiming at: fAimingCoords[0], fAimingCoords[1], fAimingCoords[2] */
    }
    return 1;
}
