Back Button

Solar2D Composer
#1

Hello! I’m using Storyboard and attempting to create a back button that returns the user to the screen they were previously at. The back button is currently on a tabBar, so I want it to “figure out” what the previous screen was and then go to that screen when the back button is pressed.
Can anyone share their knowledge?

Thanks!

Hi,
I’m just an newbie so take advice with that in mind.

I would think using a global variable to identify the previous storyboard scene could be used somehow.

By putting one line kind of like - previousScene = “scene.lua”
inside the change.scene function or what ever function you use to go forward in the game

function changeScene(e)
if(e.phase == “ended”) then
previousScene = “scene.lua”
storyboard.gotoScene(e.target.scene)
end
end

then on your back function
use that variable somehow.

I’ve never tried it - i tend to use menu buttons - ie push it and it goes back to the menu screen
I started out with a number of scenes but in order to make the code “prep” ready for any problems - figured out how to make some KEY variables global then slam in some if’s - elseif’s to take the code down to a - main/Menu/How2/Game kind of situation, where Game does all the heavy lifting under multiple situations.

See: http://docs.coronalabs.com/api/library/storyboard/getPrevious.html

This will return you the previous scene name that you can then pass to gotoScene() [import]uid: 199310 topic_id: 35563 reply_id: 141363[/import]

Thanks for the replies.

The following is what worked for me.
 

local previousScene = storyboard.getPrevious() storyboard.gotoScene( previousScene )

Thanks for giving me your time. I appreciate it. [import]uid: 39302 topic_id: 35563 reply_id: 141378[/import]
