Description

Description:

Adds an event handler to a given unit. For more information about event handlers and their types check the scripting topic Event handlers in this reference. You may add as many event handlers of any type as you like to every unit. For instance, if you add an event handler of type "killed" and one already exists, the old one doesn't get overwritten. Use removeEventHandler to delete event handlers. Every event will create an array named _this, which contains specific information about the particular event. (e.g. the "killed" EH will return an array with 2 elements: the killed unit, and the killer.)

Multiplayer:

Some event handlers are persistent (i.e. they stay attached to a unit, even after it dies and respawns). Template:EffArg "Killed" and "Hit" eventhandlers are executed where given unit is local.

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!
