you can store the history in a linear list variable, probably need to
patch all of your navigation button scripts to store destination
marker-frames, or have a 'recording'score script at each page entry
point.


on recordNewPage -- just entered a page
global history
if not listp(history) then history = [] -- first access
append history, markerp(0) -- current or first marker to left
end


on backStepHistory -- version that forgets backed out of pages
global history
if listp(history) then -- have some
go to history[count(history)]
deleteAt history, count(history)
end



to backup and not forget any pages, a global variable indexing to
current point in history would be needed. It can get trickey if a user
has backed up a few, then uses menu navigation to visit new and already
visited pages, inserting into middle ofhistory olist may be vccalled for.

Hi,


The logic that needs to be implemented is :

1. Create a global list (this list is used to hold all the marker names, alternativly you can use labellist, a list is similar to an array)
2. Create as many markers as you want
3. On the next button , ensure that the current marker name is added to this global list, this will confirm that the user has visited this scene. Have this for all your scenes.
4. When the history button is clicked, all you need to do is go to the last element of the global list.


Sample Code (Movie Script)

global mylist
on startmovie
mylist=[]
end

next button

global mylist
on mouseup
go next
append mylist, the framelabel
end

history button script

on mouseup
global mylist
mymarker=getlast(mylist)
go mymarker
end

This should work..., i've made a more elaborate program, instead of having the history logic in one movie, i create another movie at run time...this new movie has all the marker names (scenes) that you've visited.

Hope this helps or gives you an idea....
