Aborting an airdrop isn't very realistic, how come a player swallow the drop by pressing a key!

And that command /pickairdrop can very easily be made from OnPlayerKeyStateChange.
Here is the snippet:

pawn Код:

CMD:pickairdrop(playerid)
{
        //the player will be not allowed to pickup the airdrop while in a vehicle
        if(! IsPlayerInAnyVehicle(playerid))
        {
            //looping through all airdrops
            for(new i; i < MAX_AIRDROPS; i++)
            {
                //if the airdrop slot is occupied
                //i.e. the airdrop exists
                if(gAirdrop[i][a_exist])
                {
                    //if the airdrop is on the ground, dropped
                    if(gAirdrop[i][a_droped])
                    {
                        //now using 'IsPlayerInRangeOfPoint', we will check if the player is near that airdrop
                        //The range is 5.0 and resonably fine. You may increase or decrease it if you wish
                        if(IsPlayerInRangeOfPoint(playerid, 5.0, gAirdrop[i][a_pos][0], gAirdrop[i][a_pos][1], gAirdrop[i][a_pos][2]))
                        {
                            //if the player is near the drop...

                            //We will apply a picking animation just for realisticity :)
                            ApplyAnimation(playerid, "MISC", "pickup_box", 1.0, 1, 1, 1, 1, 0);

                            //the gametext showing the player is picking the drop
                            GameTextForPlayer(playerid, "~b~~h~~h~~h~Picking...", 2000, 3);

                            //now we will make a timer to destroy the airdrop after 2 seconds
                            //the anim will be ovver by then
                            KillTimer(gAirdrop[i][a_expire_timer]);
                            gAirdrop[i][a_expire_timer] = SetTimerEx("OnPlayerPickupAirdrop", 2000, false, "ii", playerid, i);
                            gAirdrop[i][a_droped] = false;

                            //break the loop
                            break;
                        }
                    }
                }
            }
        }
        return 1;
}

And the message can be easily displayed when the airdrop is dropped on the ground, i.e. use SendClientMessage or anything else to notify players in OnObjectMoved.
