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!

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
- According to this post http://forums.bistudio.com/showthread.php?167822-Stacked-event-handlers-OnEachFrame-OnPlayerConnected-etc the intention of these functions is for community/official content compatibility, thus the need for consistent functionality - I don't think you'll see them change this (although its easy enough for you to implement yourself for a specific need).
- In addition, your code will only return the bool of the last iterated _data. Perhaps this should be run through the forums first --Strangepete (talk) 03:46, 9 December 2014 (CET)
