Alrite, so step up in the scripting I need to modify a spectating script by Heinblood (from turning into seagul functionality to move up to object, use the action and spectate, then hit esc functionality)

His code, slightly modified by me and not bothered by all details

//gdtmod_seagull.sqf

//===========================

while {true} do {

gdtmod_seagull_players = [];

gdtmod_seagull_players_count = count gdtmod_seagull_players - 1;

 sleep 0.25;
};

What I did there is added for player the ability to press escape to get back out from the spectating script (which works), the problem was that all added display event handlers would work, which is not what we want, we want to remove them.

_keydown_esc = (finddisplay 46) displayaddeventhandler ["keydown", "
if ((_this select 1) in [1]) then {  
	gdtmod_seagull_camera cameraeffect [""terminate"",""back""];
	(finddisplay 46) displayRemoveAllEventHandlers ""KeyDown"";
};
"];

so I added 

(finddisplay 46) displayRemoveAllEventHandlers ""KeyDown"";

But that just crashes the game. What to do?

why are you using all those ""double"" qoutes?

unless the code is inside "qoutes" just use "regular". also in some cases ' works better than ""

Ok cool didnt know about '. Thought you have to use "" when code is inside "whatever" and it needs another "". 

_keydown_esc = (finddisplay 46) displayaddeventhandler ["keydown", " whatever 
"];

	if ((_this select 1) in [1]) then {  
	gdtmod_seagull_camera cameraeffect [""terminate"",""back""];
	(finddisplay 46) displayRemoveAllEventHandlers ""KeyDown"";
};

Weird 

		(finddisplay 46) displayRemoveAllEventHandlers 'MouseButtonDown';
	(finddisplay 46) displayRemoveAllEventHandlers 'mousezchanged';

arent causing any crash just the 

(finddisplay 46) displayRemoveAllEventHandlers ""KeyDown"";

On are unrelated topic I have 2 questions that might be important.

1. I am calling the script from a object like so:

this addAction ["Spectate", "rscripts\gdtmod_spectator.sqf"];

What is the difference between that and 

this addAction ["Spectate", "[] execVM rscripts\gdtmod_spectator.sqf"];

2. Would it be wise to somehow terminate that script once player is no longer spectating? With http://community.bistudio.com/wiki/terminate?

Can you run the terminate command within the script to terminate itself?
