Description

Description:
🕖
This information is obsolete as of Arma 3 v1.58. Reason: Arma 3: Mission Event Handlers should be used instead.

Stacks an event handler. All event handlers accept user arguments, which are passed to the EH code in _this variable. If the EH has own params returned in _this variable as well, user arguments are appended to the end of _this array. Note that if you try to add an empty EH, i.e. with empty code, it will simply be ignored.

Supported Event Handlers
Scripted Event Handler Mission EH Equivalent Description
"onEachFrame" EachFrame N/A
"onPlayerConnected" PlayerConnected Special variables _id, _uid, _name, _jip, _owner are provided and are available in _this array as well.

params ["_id", "_uid", "_name", "_jip", "_owner"];

"onPlayerDisconnected" PlayerDisconnected
"onMapSingleClick" MapSingleClick Special variables _units, _pos, _alt, _shift are provided and are available in _this array as well.

params ["_units", "_pos", "_alt", "_shift"];

"onPreloadStarted" PreloadStarted N/A
"onPreloadFinished" PreloadFinished N/A
Execution:
call
Multiplayer:
This command has the same locality as addMissionEventHandler.
Groups:
Event Handlers

Syntax

Syntax:
[id, event, code, arguments] call BIS_fnc_addStackedEventHandler
Parameters:
id: String - custom id, a unique identifier. Adding same type of EH with the same id will overwrite existing
event: String - event handler name, see description for supported EHs
code: Code or String. The String is treated as function name
arguments: Array of Anything - arguments to make available in code in _this array
Return Value:
String - custom id on success or "" on failure

Examples

Example 1:
["someId", "onEachFrame", { hintSilent str time }] call BIS_fnc_addStackedEventHandler;
Example 2:
["someId", "onEachFrame", {hintSilent str position (_this select 0)}, [player]] call BIS_fnc_addStackedEventHandler;
Example 3:
private _eventName = "OnEachFrame"; missionNamespace getVariable [format ["BIS_stackedEventHandlers_%1", _eventName], []]; // gets an array with all existing ids

Additional Information

Stacking all the code into one PFH will be less demanding than separated calling within multiple PFH, e.g:
{ [format ["%1", _forEachIndex], "onEachFrame", _code, [_x]] call BIS_fnc_addStackedEventHandler; } forEach [var0, var1, varN, var100]; // pretty demanding
[_id, "onEachFrame", { { _x call _code } forEach [var0, var1, varN, var100]; }] call BIS_fnc_addStackedEventHandler; // faster, only one event
