Is there a way when you are hiding an overlay via hideOverlay to pass parameters back to the parent scene that can then be picked up in the overlayEnded event listener?
I have an overlay I would like to show that picks up some user input and I would like that passed back to the calling scene. [import]uid: 92150 topic_id: 30229 reply_id: 330229[/import]
I’m sure this is the completely wrong way to go about this, but I can pass the parent scene in the parameters to the overlay, modify a variable in the overlay tied to the scene that was passed and then close the overlay and it will show up in the parent scene:
--------parent scene --------------
local storyboard = require("storyboard")
local scene = storyboard.newScene()
local function openOverlay()
local options = {
params = { parent\_scene = scene }
}
storyboard.showOverlay("myoverlay", options)
end
function scene:createScene(event)
end
--other functions
function scene:overlayEnded(event)
print(self.my\_new\_var) end
------other parent scene code here to make scene show-----
-----------------------------------------
--------------Overlay scene snippet----------------
local storyboard = require("storyboard")
local scene = storyboard.newScene()
local parent\_scene = nil
local function closeOverlay()
parent\_scene.my\_new\_var = "TESTING"
storyboard.hideOverlay()
return true
end
function scene:createScene(event)
local group = self.view
parent\_scene = event.params.parent\_scene
----extra stuff below
end
return scene
-------------------end overlay snippet----------- Thoughts on this approach? Sounds highly wrong as it would be passing the whole scene object to the overlay. That screams memory problems. Any better ways to accomplish this?

Interested to know if there are alternatives as well. =) [import]uid: 70056 topic_id: 30229 reply_id: 138652[/import]

You can do it like this. From the overlay scene set a parameter to non overlay scene.
[lua]local non_overlay_scene = storyboard.getScene( ‘non_overlay_scene’ )
non_overlay_scene.whatToDo = ‘test’[/lua]
And from your non_overlay_scene.lua file which is the non overlay scene you can access that whatToDo from the scene object as follows.
[lua]local scene = storyboard.newScene()
–[[
…
…
…
]]–
function scene:overlayEnded( event )
print(scene.whatToDo) – This will print ‘test’ to the console
end
scene:addEventListener( “overlayEnded” )
[/lua]
