Do you mean you want your character image to be removed when you click back and go to the menu scene?

The reason the character stays on screen is you haven’t added it to a display group so it is not cleaned up automatically, and in your code your backTitle() function is never called to do this manually.

What I do is put this at the top of each scene:
[lua]local localGroup = display.newGroup()[/lua]

Within create scene, instead of:

[lua]local group = self.view[/lua]

I use:

[lua]localGroup = self.view[/lua]

This way, every object is added to a display group (localGroup) that I can reference from other functions in the scene, so I can manipulate the alpha value, position, rotation etc of the whole scene. I might group my objects into hudGroup, popupGroup, finishGroup etc and then insert those to localGroup, so I can manipulate common groups of objects in one go (i.e. move a popup that I initialised off screen into view).

I can also then add objects to localGroup outside of create scene if I need to (i.e. changing images on the fly dependent on game status).

When I perform storyboard.loadScene to go elsewhere, all these objects are automatically removed from screen and memory for me. [import]uid: 93133 topic_id: 29649 reply_id: 119007[/import]
