Description

Description:

Adds an Event Handler to the given object. Event Handler parameters are accessiable via the _this inside the code.

• Since Arma 3 v.1.63.137807 the Event Handler index is available as _thisEventHandler during Event Handler 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.

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

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!
