Can anyone tell me what is wrong with this picture? I’m trying to clean up the storyboard scene by moving code into external modules, trees.lua in this example. Calling a function in trees.lua within createScene works just fine, but calling any function in trees.lua or any other module from enterScene or an enterFrame event returns a runtime error: “attempt to call field ‘plantTree’ (a nil value).”
I need to be able to call functions in modules during enterFrame events within storyboard scenes.
local storyboard = require( "storyboard" )
local scene = storyboard.newScene()
---------------------------------------------------------------------------------
-- BEGINNING OF YOUR IMPLEMENTATION
---------------------------------------------------------------------------------
local trees = require "trees.lua"
-- Called when the scene's view does not exist:
function scene:createScene( event )
local group = self.view
trees.plantTree() \<
end
-- Called immediately after scene has moved onscreen:
function scene:enterScene( event )
local group = self.view
local function gameLoop(event)
trees.plantTree() \< end
Runtime:addEventListener("enterFrame", gameLoop)
end
-- Called when scene is about to move offscreen:
function scene:exitScene( event )
local group = self.view
end
-- Called prior to the removal of scene's "view" (display group)
function scene:destroyScene( event )
local group = self.view
end
---------------------------------------------------------------------------------
-- END OF YOUR IMPLEMENTATION
---------------------------------------------------------------------------------
-- "createScene" event is dispatched if scene's view does not exist
scene:addEventListener( "createScene", scene )
-- "enterScene" event is dispatched whenever scene transition has finished
scene:addEventListener( "enterScene", scene )
-- "exitScene" event is dispatched before next scene's transition begins
scene:addEventListener( "exitScene", scene )
-- "destroyScene" event is dispatched before view is unloaded, which can be
-- automatically unloaded in low memory situations, or explicitly via a call to
-- storyboard.purgeScene() or storyboard.removeScene().
scene:addEventListener( "destroyScene", scene )

return scene I originally had the enterFrame event outside of enterScene, but trees.plantTree still returned the same runtime error. [import]uid: 99903 topic_id: 23546 reply_id: 323546[/import]
