Description

Description:

Adds an Event Handler (EH) to the given object.
If the EH provides parameters when firing (e.g. the "Killed" EH will provide an array with the killed unit and the killer), those are available as _this.
Since Arma 3 v.1.63.137807 the EH index is available as _thisEventHandler during EH code execution.

You can add as many Event Handlers of any type as you like to every unit, existing Event Handlers do not get overwritten. Use removeEventHandler to remove an Event Handler.

Read Event Handlers for more information and a list of all available Event Handlers.

Multiplayer:

Some event handlers are persistent (i.e. they stay attached to the unit, even after it dies and respawns).

Groups:

When using overridable EH, such as "InventoryOpened" and similar, where returning true allows to override default action, exitWith cannot be used to return value. So: if (whatever) exitWith {true}; false; Forget about it, will not work. Instead use: if (whatever) then {true} else {false}; 100% satisfaction guaranteed!
