Check classname is grenade (or throwable)

[Zriel 12]

So, I'm working on a loadout system, and I would like to know if there is a way to check if a classname is a grenade (or is a throwable item, or at least I think that's how they are called on arma configs)

I currently can check if a classname is a magazine used by a weapon, but grenades and such seem to use a different set of configs.

 

Any common config item I should be looking for?

Have you had a peek here? https://community.bistudio.com/wiki/currentThrowable

Query the magazines of each subclass of ( "CfgWeapons" >> "Throw" )

_item = "SmokeShell";
_isThrowable = count ( "
	_item in getArray( _x >> 'magazines' ) 
"configClasses ( configFile >> "CfgWeapons" >> "Throw" ) ) > 0;

Same can be done for explosives and mines by using "Put"

Nah, item is not given, I wan't to be able to check this before giving it to the unit.

 

Query the magazines of each subclass of ( "CfgWeapons" >> "Throw" )

_item = "SmokeShell";
_isThrowable = count ( "
	_item in getArray( _x >> 'magazines' ) 
"configClasses ( configFile >> "CfgWeapons" >> "Throw" ) ) > 0;

Yay! this is working perfectly. Many thanks!

AFAIK this should work too:

"className" isKindOf "Throw" <- No this does not work!
// Returns true or false

Read the comments in the BIS Arma Wiki for other possible solutions:

This works:

(getText(configfile >> "CfgMagazines" >> "className" >> "selectionFireAnim") == "zasleh");
 
But the solution posted by Larrow is actually the most reliable so you should stick to this.

"configClasses ( configFile >> "CfgWeapons" >> "Throw" ) ) > 0;

 

Seems like I found a much faster way to determine whether the item is throwable:

Fn_Gear_IsThrowable = {	
	private _cfa = configFile >> "CfgAmmo" >> getText(configFile >> "CfgMagazines" >> _this >> "ammo");
	while {true} do {
		if (not isClass _cfa or {configName _cfa isEqualTo "GrenadeHand"}) exitWith {isClass _cfa};
		_cfa = inheritsFrom _cfa}
};

magazines player select {_x call Fn_Gear_IsThrowable}
//Result: ["Chemlight_green","SmokeShell","SmokeShellGreen","Chemlight_green","HandGrenade","HandGrenade"]

Careful on how/where you use that, it will return UGL magazines as throwable plus a host of vehicle ammo.

You could nearly double its speed by using isKindOf instead of the while loop.

_isThrowable = "1Rnd_SmokeOrange_Grenade_shell" call {
    params[ "_item" ];
    
    private _cfa = configFile >> "CfgAmmo" >> getText(configFile >> "CfgMagazines" >> _item >> "ammo");
    configName _cfa isKindOf "GrenadeHand"
};

is TRUE

You're right. First aproach failed. Second aproach:

Fn_Gear_IsThrowable = {
	{if (_this in getArray (configFile >> "CfgWeapons" >> "Throw" >> _x >> "magazines"))
			exitWith {true}; false} forEach getArray (configFile >> "CfgWeapons" >> "Throw" >> "muzzles")
};

Filters grenadier inventory for ~0.027ms, your version for ~0.037ms. Thank you.

Try this:

fn_isThrowable = 
{	
	private _cfgMagazine = configFile >> "CfgMagazines" >> _this;
	if (getNumber (_cfgMagazine >> "initSpeed") < 30) exitWith
	{
		toLower getText (configFile >> "CfgAmmo" >> getText (_cfgMagazine >> "ammo") >> "simulation") in [
			"shotgrenade", 					
			"shotsmokex",
			"shotsmoke", 
			"shotsubmunitions", 
			"shotdeploy", 
			"shotilluminating", 
			"shotshell", 
			"shotnvgmarker"
		]
	};
	false
};

Try this:

Works fine, ~80 times faster than my variant

Added: A new BIS_fnc_isThrowable function (determining if the magazine of a given class name is throwable)
