is it possible to create a await function?

for example..

 
if await(60,"my identifer") then
 --done
end

here is my code

 
function await(t,id)
  if not cofun[id] then
    --don't know how to return true here
    add(cofun,cocreate(function()
      while t>0 do
        t-=1
	yield()
      end
    end))
  else
   return false
  end	
end

function coupdate()
 for c in all(cofun) do
  if costatus(c) then
    coresume(c)
  else
    del(cofun,c)
  end
 end
end

EDIT: idk if this is possible but maybe something like this..

 
--id is determined by function execution index
if await(60) then
 --done
end

for example..

 
await(60)--await id 0
await(60)--await id 1
await(60)--await id 2
--nextframe
await(60)--await id 0
await(60)--await id 1
await(60)--await id 2



yield cannot return value - so you need to provide a function to your await that will be triggered when done.
Something like:

 
function wait_async(t,fn)
	return cocreate(function()
	 -- wait...
		for i=1,t do
		 yield()
		end
		-- trigger user code
		fn()
	end)
end

c=wait_async(60,function()
 print("done")
 end)

function _update()
  coresume(c)
end


huh odd I guess I could do this with a timer instead of coroutines.

thankyou
