BIS fnc addStackedEventHandler – Talk

Not being able to override default engine behavior was really bumming me out, so I took a look at BIS_fnc_executeStackedEventHandler. By adding 2 variables, I was able to make the function perform as intended (as I see it). Please push this fix to the next hotfix, BIS!

/* Author: Nelson Duarte Edit by: Dread (in bold)

Description: This function executes the stacked items, should not be called independently

Parameter(s): _this select 0: STRING - The onXxx event handler

Returns: BOOL - True if executed code returns true False if executed code returns anything else

/Parameters

private ["_event"];
_event = [_this, 0, "", [""]] call BIS_fnc_param;
//Mission namespace id
private "_namespaceId";
_namespaceId = "BIS_stackedEventHandlers_";
//Mission namespace event
private "_namespaceEvent";
_namespaceEvent = _namespaceId + _event;
//The data
private "_data";
_data = missionNameSpace getVariable [_namespaceEvent, []];
//Add 2 new variables and define
private ["_return","_trash"];
_return = false;
_trash = false;
//Process data
{
	//Data item parameters
	private ["_code", "_arguments"];
	_code		= [_x, 2, "", [{}, ""]] call BIS_fnc_param;
	_arguments	= [_x, 3, []] call BIS_fnc_param;
	if (typeName _code != typeName "") then {
		//Execute code
		_trash = _arguments call _code; //call can return, why waste?
	} else {
		//Execute function
		_trash = _arguments call (call compile _code); //not really sure what's happening here. 2 calls?
	};
	if (typeName _trash == "BOOL") then
	{
		if (_trash) then
		{
			_return = true;
		};
	};
} forEach _data;

//Return _return; Can't get this post formatted correctly. I'm just going to leave it like it is. - DreadedEntity
