UI functions don't seem to work from a coroutine

[JohnEmhoff]

Hello! I get an odd error when I call nuklear functions from a coroutine:

Error

main.lua:25: bad argument #1 to 'resume' (Nuklear context expected, got thread)

Traceback

[love "callbacks.lua"]:228: in function 'handler'
[C]: in function 'resume'
main.lua:25: in function 'draw'
[love "callbacks.lua"]:168: in function <[love "callbacks.lua"]:144>
[C]: in function 'xpcall'

Here's a minimal reproduction:

local nuklear = require('nuklear')
local nuk_ui
local co

function ui_one_frame()
   nuk_ui:frameBegin()
   if nuk_ui:windowBegin('Window', 100, 100, 600, 160,
          'border', 'movable', 'title') then
      nuk_ui:layoutRow('dynamic', 30, 1)
      nuk_ui:label('Hello, world!')
   end
   nuk_ui:windowEnd()
   nuk_ui:frameEnd()
end

function ui_stuff()
   while true do
      ui_one_frame()
      coroutine.yield()
   end
end

function love.draw()
   love.graphics.clear(0, 0, 0, 1)
   coroutine.resume(co)
   --ui_one_frame()
   nuk_ui:draw()
end

function love.load(_aa, _b)
   nuk_ui = nuklear.newUI()
   co = coroutine.create(ui_stuff)
end

As far as I can see it's failing on the call to windowBegin(). If I replace the coroutine.resume call with ui_one_frame (i.e. call the nuklear functions from the main coroutine) things work fine. Is this expected behavior?

This is addressed in 829dc15. Let me know if this solves your issue.

New binaries can be found on the Releases page.

Works great, thanks! Thanks for the quick fix (which looked kind of annoying as well).

Ha, yeah it was a little annoying! 😄

Glad it's fixed.
