script "Taking over" a key?

[galzohar]

I want to try something in a mission and for that I need to disable the CQB sights key. Is there an easy way to make the mission override whatever key the user have bound for CQB sights to instead do nothing?

Guess I answered myself on this one:

disableSerialization;
waitUntil {!isNull (findDisplay 46)};
(findDisplay 46) displayAddEventHandler ["KeyDown",
"
	private['_handled'];
	_handled = false;
	_key = _this select 1;
	if (_key in (actionKeys 'OpticsMode')) then
	{
		_handled=true;
	};
	_handled;
"];

Hmm, could you use that to trap "Sprinting" too? I wanted to force the player to walk and I can do that but they can still sprint just fine (double tap W).

Probably same thing would work for sprinting if you just guess the key name correctly - worth trying. You could even add a check in the handler's code that returns false if sprinting is enabled and only returns true when it's disabled, so you don't have to create/remove the handler.

I've had no luck with this. I've figured out that "W" = 17, and the actionKeys for MoveFastForward (sprinting) is 273, but I can't for the life of my trap "MoveFastForward" being active...

Anyone know how to capture MoveFastForward to disable sprinting or how you capture a x2 keystroke?

Hmm - if the engine doesn't automatically coalesce the double-tab then the next best thing would be to add a timer in your key handler to detect this. Something like...

wActive=0;
wPressed={
    wActive=wActive+1;
    sleep 0.5; //exact delay may need some tweaking
    wActive=wActive-1;
};


keyDown={
    private ["_handled"];
    _handled = false;
    //walkbindings is an array of dik-codes for 'walk' action
    if ((_this select 1) in WalkBindings) then {
        _handled = (wActive >0) ;
        [] spawn { call wPressed};
    };
    _handled;
};

(findDisplay 46) displayAddEventHandler ["KeyDown","this call keyDown"];
