Keep createDisplay open

[sizraide 4]

Hello, I'm creating a singleplayer scenario.

I created a GUI to choose difficulty for a singleplayer mission at the beginning of the mission.
 

But the GUI can be closed by pressing ESC, I wonder if there's any countermeasures to avoid that? So the player can't close it until he chooses a difficulty.

displayAddEventHandler ["keydown" .....] override escape key https://community.bistudio.com/wiki/User_Interface_Event_Handlers#onKeyDown

_displayHandler = (findDisplay 46) displayAddEventhandler["KeyDown",{

	if (_key == 1) exitWith {true};

(findDisplay 46) displayRemoveEventHandler ["KeyDown", _displayHandler];

I made an displayEventHandler, this doesn't seem to be working? Any clues?


When I press ESC, it still closes the display. But no error pops up.

Hi @sizraide
Try this with your original code:
 

// Add UI EventHandler
_displayHandler = _display displayAddEventhandler["KeyDown",{
	params ["_displayOrControl", "_key", "_shift", "_ctrl", "_alt"];
	private _rewriteKey = FALSE;
	if (_key == 1) then {systemChat "button esc clicked";_rewriteKey = TRUE;};
	_rewriteKey
}];

// Remove displayHandler
_display displayRemoveEventHandler ["KeyDown", _displayHandler];

I´ve added eventhandler to your created display instead of mission display for the clarity purposes. Just to be sure you might also consider using disableSerialization. I´m not sure if this is actually needed but i personally use it every time i work with scripts that are using UI elements. Let me know if that helped 🙂

For some reason exitWith will not overwrite the event. try if else instead:

_displayHandler = (findDisplay 46) displayAddEventhandler["KeyDown",{
	params ["_display","_key"];
	if (_key == 1) then {
		true
	} else {
		false
	};
}];

// or even more simple:
_displayHandler = (findDisplay 46) displayAddEventhandler["KeyDown",{
	params ["_display","_key"];
	_key == 1
}];

Appreciate the help!

I managed to fix it here:

// Open GUI
_display = findDisplay 46 createDisplay "chooseDifficulty";

// Add UI EventHandler
_display displayAddEventhandler["KeyDown",{
	params ["", "_key"];
	_key == 1
}];

// Wait for confirmation
waitUntil{ok};

// Enable borders
[0, 0, false, true ] spawn BIS_fnc_cinemaBorder;

// Remove displayHandler
findDisplay 46 displayRemoveAllEventHandlers "KeyDown";

// Close display finally
_display closeDisplay 1;
