</div>

@t1 = Thread.new do  
b = false  
until b == true  
sleep 10  
puts “you are getting cold!”  
end  
end

So, that gets called when a play enters a ‘cold’ room. I want to set in  
the ‘leave’ event:

@t1.close

or something to that effect, but i get errors when trying to call  
@t1.exit… Any thoughts?

You can call @t1.raise or @t1.kill, however those methods are pretty  
scary. I’d do something like polling:  
b = false  
@t1 = Thread.new { sleep 10 until b == true}  
and set b to true elsewhere in the code.
