Configured the key. How is key cancel?

[demor140202]

  Hi Quarchodron, and other programmers.

I know how to configure the keys by clicking on which something will happen. But how do I cancel these settings? How do I make the key stop calling an action? 

Code:

            addEventHandler("onKey",function(key)
{
    if (key == KEY_7)
    {
setFreeze(true);
    }
})

I need "F7" to work as a freeze initially.
And then return " F7 " to its original form, so that the key does not start freezing.

All that happens is that I delete the "onKey" event . And in General, everything stops working (chat, list of players)

Hm.. that depends of your "needs".
If you only want a F7 key to stop working after pressing it, you can always write something like this:

Squirrel Script

local freezeKeyPressed = false
 
addEventHandler("onKey", function(key)
{
	switch (key)
	{
		case KEY_F7:
			if (!freezeKeyEnabled)
			{
				setFreeze(true)
				freezeKeyEnabled = true
			}
			break
	}
})

In order to re-enable the F7 functionallity, change the content of the "freezeKeyEnabled" variable back to "false".
Also, maybe you don't want to "disable" the key, but rather after pressing it second time, call the setFreeze(false).

To do that, you can make something like this:

Squirrel Script

local menuVisible = false // dummy variable for example purposes
 
addEventHandler("onKey", function(key)
{
	switch (key)
	{
		case KEY_F7:
			menuVisible = !menuVisible // negating a variable content
			setFreeze(menuVisible)
			break
	}
}

Also, do note, that you can add more than one function to a specific event using addEventHandler function.

Thanks, buddy.
