Pass local variable in displayAddEventHandler

[Grenadier ITF 6]

As the title suggests I can't pass the _target variable.

_target = _this select 0;
 

_id=(findDisplay 46) displayAddEventHandler ["KeyDown", 

   

   "if(_this select 1==22)then {_nul =[_target] execVM 'koc.sqf'};"];

any suggestions would be welcome :))

Target has to be defined within the scope of your event handler action. You can store/retrieve it in missionnamespace for example. It depends on what type of data you are trying to pass.

Or store _target on the display using setVariable, then retrieve it from the display inside the EH. Rather than using a global variable.

Spoiler

_target = _this select 0;
findDisplay 46 setVariable[ "TAG_target", _target ];

_id = findDisplay 46 displayAddEventHandler[ "KeyDown", {
	params[ "_display", "_keyCode", "_shft", "_ctr", "_alt" ];
	
	if ( _keyCode == 22 ) then {
		_target = _display getVariable "TAG_target";
		_nul = [ _target ] execVM 'koc.sqf';
	};
}];

the target is an object, vehicle, unit or other

Resolved. thank you guys

_target = _this select 0;

missionNamespace setVariable ["YourString",_target];

   

   _id=(findDisplay 46) displayAddEventHandler ["KeyDown", 

   

   "if(_this select 1==22)then {
       _target = missionNamespace getVariable 'YourString';

       _nul =[_target] execVM 'koc.sqf'};"];

DONE!

Then, same as:

YourString = _this select 0;

_id=(findDisplay 46) displayAddEventHandler ["KeyDown", {

   if(_this select 1==22)then {
       [YourString] execVM "koc.sqf"

   };

}];
