Returning nearest mine reliably around player

[R3vo 2652]

I am searching for a way to return all sorts of mines (IEDs, tripwire, AT so on and so forth) reliably around the player. Looping through allMines is not an option.

 

I found out that nearestObject [player, mineBase]; only returns AT mines for some reason. Does anyone know the other base classes?

_mine = nearestObject [player, "mineBase"]; //returns "UnderwaterMineAB_Range_Ammo","ATMine_Range_Ammo","APERSMine_Range_Ammo","UnderwaterMine_Range_Ammo";

I am still missing the tripwire, bounding, slam and ieds.

 

 

 

 

Edit: I fixed the issue by sorting the array returned by allmines by distance.

Revo_fnc_sortMinesDistance =
{
//by jezuro
_unsorted = _this select 0;
_sortedMines = [];
_pos = position player;

{
     _closest = _unsorted select 0;
     {if ((position _x distance _pos) < (position _closest distance _pos)) then {_closest = _x}} forEach _unsorted;
     _sortedMines = _sortedMines + [_closest];
     _unsorted = _unsorted - [_closest]
} forEach _unsorted;

_sortedMines
};

If anyone has got a faster alternative please let me know.

The thing I dislike of your code is (position _closest distance _pos).. you know already the distance from the closest to _pos, so store it in a variable, if not, the command is executed on every iteration.

 

Anyway, you should check BIS_fnc_sortBy, which maybe suits your needs.

Thanks for your feedback, but position _closest may change on each run until the array is completely sorted. Anyways, I replaced this function with BIS_fnc_sortBy.

 

 

nearestObject [player, "MineGeneric"]

 

 

Thanks, may I know from where you've got that MineGeneric class ?

 

Edit: Tested your code, it unfortunately does also not detect all type of mines.

What fails?

[R3vo 2652]

Nothing fails, it simply does not detect tripwire mines and if I remember correctly slam mines.

Mine detection is all kinds of FUBAR.. 

 

nearestObject [player,"TimeBombCore"]

 

TimeBombCore will detect most explosives....

 

"APERSBoundingMine_Range_Ammo"

"APERSMine_Range_Ammo"

"APERSTripMine_Wire_Ammo"

"ATMine_Range_Ammo"

"ClaymoreDirectionalMine_Remote_Ammo"

"DemoCharge_Remote_Ammo"

"IEDLandBig_Remote_Ammo"

"IEDLandSmall_Remote_Ammo"

"IEDUrbanBig_Remote_Ammo"

"IEDUrbanSmall_Remote_Ammo"

"SatchelCharge_Remote_Mag"

"SLAMDirectionalMine_Wire_Ammo"

"UnderwaterMineAB_Range_Ammo",

"UnderwaterMine_Range_Ammo",

"UnderwaterMinePDM_Range_Ammo"

 

MineGeneric [ x, found, x, found, x, x, x, x, x, x, x, x, found, found, found ]
MineBase [ x, found, x, found, x, x, x, x, x, x, x, x, found, found, found ]
TimeBombCore [ found, x, found, x, found, found, found, found, found, found, found, found, x, x, x ]

Same order as listed above. Note the classes not detected by TimeBombCore, yet..

"APERSMine_Range_Ammo" isKindOf "TimeBombCore"  //true

"TimeBombCore" in ([(configfile >> "CfgAmmo" >> "APERSMine_Range_Ammo"),true] call BIS_fnc_returnParents) //true

"ATMine_Range_Ammo" isKindOf "TimeBombCore" //true

"TimeBombCore" in ([(configfile >> "CfgAmmo" >> "ATMine_Range_Ammo"),true] call BIS_fnc_returnParents)  //true

"UnderwaterMineAB_Range_Ammo" isKindOf "TimeBombCore" //true

"TimeBombCore" in ([(configfile >> "CfgAmmo" >> "UnderwaterMineAB_Range_Ammo"),true] call BIS_fnc_returnParents) //true

"UnderwaterMine_Range_Ammo" isKindOf "TimeBombCore" //true

"TimeBombCore" in ([(configfile >> "CfgAmmo" >> "UnderwaterMine_Range_Ammo"),true] call BIS_fnc_returnParents) //true

"UnderwaterMinePDM_Range_Ammo" isKindOf "TimeBombCore" //true

"TimeBombCore" in ([(configfile >> "CfgAmmo" >> "UnderwaterMinePDM_Range_Ammo"),true] call BIS_fnc_returnParents) //true

 

You could do something like...

_mines = [ nearestObject [ player, "MineBase" ], nearestObject [ player, "TimeBombCore" ] ];
_nearest = [ +_mines, [], { _x distanceSqr player }, "ASCEND", { !isNull _x } ] call BIS_fnc_sortBy select 0;

If you dont want to iterate allMines

[R3vo 2652]

Thanks for your input Larrow, definitely gonna try that, it should improve performance quite abit. In addition I'll open a Ft ticket since in my opinion all mines should inherit from mineBase or mineGeneric.

 

 

Edit: Your code works like a charm.

 

 

Thanks to everyone for your input !
