Is there an event handler to detect a change in knowsAbout?

[Luft08 27]

I'm looking to improve my code that checks to see if a group's knowledge of the players changes.  Right now I use code that I repeatedly call using the BIS_fnc_loop function. I was hoping there would be an event handler which would be more efficient but I don't see it.

 

Thanks.

fn_knowsabout_handler = 
	{
		params ["_target", "_who", "_wait"];
		
		while {true} do 
			{
				private _knowsAbout = _who knowsAbout _target;								
				
				waitUntil 
					{
						sleep _wait;
						
						if (_who knowsAbout _target isNotEqualTo _knowsAbout) exitWith 
							{
								/// Code block on change:
								
								systemchat format ["%1 knowsAbout %2 value changed from %3 to %4", _who, _target, _knowsAbout, (_who knowsAbout _target)];
							};
					};
			};
	};
	
[player, somegroup, 0.5] spawn fn_knowsabout_handler;

Thanks Ibragim A. I think the take away here is that there isn't an existing event handler to do what I want. But maybe I can add my own using addMissionEventHandler.  I'll look over your code to see if it is more efficient than mine and if it can be used in a custom event handler. (Assuming that addMissionEventHandler does what I hope it does.) Never mind. ☹️ I was excited but alas my hopes have been crushed. The addMissionEventHandlers are preexisting handlers attached to the mission. Not much hope in using them. Maybe I need to look at the code that the Eden editor uses for triggers?

Triggers (repeatable) are also loops. If an event handler doesn't exist, you can use scripted loops,   or generic onEachFrame EH with drastic conditions.

Triggers and loops are working fine. You can set the loop (and now trigger) interval. And you can decide extra conditions like knowsAbout changes. I suggest you to set a threshold for any changing value: here knowsabout can evolve from 0 to 4 and it's useless to "react" for all changes: 0.541, 0.687,... 1.488... 4. Imho the interesting threshold is 1.5.

Out of curiosity what makes 1.5 interesting?  Is that the value that something happens?
