Syntax
- Syntax:
- Syntax needed
- Parameters:
- [event, expression, args]: Array
- event: String - event name
- expression: Code or String - expression that will be executed in missionNamespace when EH fires.
- args (Optional): Array - (Since Arma 3 v2.03.147276) additional arguments to be passed to the EH code. Available during code execution via _thisArgs variable.

- Return value needed
Examples
- Example 1:
// A script could be executed to stop custom scripts graciously, or save progress & stats, for example: _id = addMissionEventHandler ["PlayerDisconnected", { systemChat str _this }];- Example 2:
- Since Arma 3 v2.03.147276:
_id = addMissionEventHandler ["EachFrame", { systemChat str [_thisArgs, time] }, [time]];
