Description

Description:: Adds a multiplayer event handler (EH) to the given object and returns EH handle. See Event Handlers.
Multiplayer:: Multiplayer EHs are added globally to every client and the server will fire on itself and every client upon event. The only exception is the MPRespawn EH that one only fires where the respawned unit is local. Make sure to check the EHs' locality in Event Handlers pages.
Groups:: Multiplayer Event Handlers

Syntax

Syntax:

object addMPEventHandler [type, expression]

Parameters:

object: Object - object to monitor

type: String - event handler name

expression: String or Code - Expression to execute.
If EH has some data to return upon event (e.g. the "MPKilled" EH will return an array with 2 elements: the killed unit, and the killer), it is passed in _this variable.

Since Arma 3 v.1.64 the EH handle is also stored in _thisEventHandler variable and is available during EH code execution.

Event Handler parameters are accessible via _this
The Event Handler type is available as _thisEvent
The Event Handler index is available as _thisEventHandler

Return Value:

Number - event handler index

Examples

Example 1:: _index = player addMPEventHandler ["MPKilled", { _this execVM "playerKilled.sqf"; }];
