- "onPreloadStarted"
- "onPreloadFinished"
- Execution:
- call
- Groups:
- Uncategorised

- arguments: Anything - arguments to make available in code
- Return Value:
- String
Examples
- Example 1:
["someId", "onEachFrame", { hintSilent str time; }] call BIS_fnc_addStackedEventHandler;- Example 2:

(ArmA3 1.22) Stack all codes 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…var100]; //pretty demanding[_id, ”onEachFrame”,{ {_x call _code} forEach [var0…var100]; }] call BIS_fnc_addStackedEventHandler; //faster

You cannot use stacked EH's and non-stacked EH's (just the normal commands, onEachFrame/onMapSingleClick/etc.) together because BIS_fnc_addStackedEventHandler utilizes these commands in it's code, overwriting a non-stacked EH.
Stacked Event Handlers are saved to missionNamespace whenever a new one is added, to view them use:
hint str (missionNamespace getVariable ["BIS_stackedEventHandlers_XXX",[]]); where "XXX" is each event name ("onEachFrame", "onPreloadStarted", "onPreloadFinished", "onMapSingleClick", "onPlayerConnected", "onPlayerDisconnected")
