Description
- Description:
- This event handler will detect if a missionNamespace variable (it is attached to) has been broadcast over network with publicVariable, publicVariableClient or publicVariableServer commands and will execute EH code upon detection. Arguments passed to the code in _this array are:
_this select 0: String - broadcast variable name (same variable name EH is attached to)
_this select 1: Anything - broadcast variable value
Please note:
* EH works only in Multiplayer environment.
* EH will not fire on the machine that executed broadcast command, only on the machines that receive the broadcast.
* The value of broadcast variable can be exactly the same, it is the actual broadcast that triggers EH not the change in variable. - Groups:
- Uncategorised

MulleDK13 note below needs some clarification. You don't "must" use postInit and you absolutely can use preInit function to initialise addPublicVariableEventHandler if you start scheduled script from it.
//script with preInit = 1; in CfgFunctions 0 = 0 spawn { "someVar" addPublicVariableEventHandler { //yourcode }; };
- MulleDK13
- Note on using addPublicVariableEventHandler during initialization: If you need a function to call addPublicVariableEventHandler during initialization, you must use postInit. addPublicVariableEventHandler does not work during preInit.

Please note that varName indicates which variable you want to monitor with this eventhandler.
As a result, the example eventhandler on this page will only fire when the variable publicThis has been changed, but not if any other variable was changed by any other client via the publicVariable command.
