I'm not quite sure what it is you are trying to achieve here.
I had a small project a while ago, before I started developing the page
wizards, that required a non-linear route through it.
I achieved it at the time by
1. each page had a number of buttons on it - these were the exit routes,
and different pages had a different number of buttons.
2. I had a destination array for each page that had an entry for each
button in it and the entry was the page name of the destination page.
3. I had a master array that had one entry in it per page, each entry
being the destination array for that page
This enabled me to identify the index of the current page and then to
use that to look up the destinations for that page in the master array.
Because the destinations are defined in separate arrays, all then held
in a master array, there would be nothing stopping you from defining a
wholly different route through the pages by simply defining set of
arrays and then using your variable to decide which array set you used,
but it could soon get horribly complicated.
I am not sure if your varying navigation will be taking place within
pages in a framework or between pages in the main interface.
For example you could have a page off the project interface that asked a
question and as a result of your answer you either went down framework A
which was linear or framework B which was linear.
If you had a number of icons to show or hide, all controlled by one
variable you could save a series of 1s and 0s e.g. 0110 which could then
be parsed by script to separate out each integer from the string so that
0110 effectively turned of icon 1, turned icons 2 and 3 on and icon 4
off.
I have no idea if any of this is any help but you never know.
Kind regards

We were going to approximate a sort of nonlinear navigation by hiding
certain icons in a number frame work(s) depending on the choice (say a
button) which the users make as the content is substantialy the same but
modified depending on the user choice (eg same frame work - different
navigation). We would like to store this choice in some variable so the
user is reminded of the choice made and have the hide/show code related
to the frame work as can see it would get very tricky if you allow
layers of choices or changes to a number of frameworks . This would
avoid breaking into several learning objects with essentially duplicated
content and avoid duplication of the choice. Forward and Back option
would allow navigation to follow a certain path depending on user choice
or based on a variable storing a previous choice. Havent tried this yet
(storing a variable to hide icons etc ) so appreciate comment.

I appreciate the points you make. Whatever facilities you build
into Xerte there will be some people who use them inappropriately.
A large learning object which is non-linear may not be completed
at one sitting and there is no save facility in Xerte to get you back to
where you were. A page that has an input box, that allows you to type in
a page name or keyword, which Xerte then uses to take you to the page
referenced by that name or key word might be one solution. A non-linear
project could offer this at the start, to enable you to jump in at a
point that you had previously achieved. Alternatively you just keep the
non-linear bits of a project relatively short, so that starting from the
beginning is not much of a hardship.
It rather depends on the learning experience you are trying to
create.
I agree there are times when you definitely want to be able to
access every / any page of a learning object in any order or
sequentially and Xerte works well for that.
There are times though - maybe as part of a learning exercise,
when you want to set the user challenges and direct their route through
the learning object based on their responses. Additionally such
sequenced learning objects can perform less as learning objects and more
as performance support resources, e.g. to guide a support person through
a trouble shooting process. In such cases you don't necessarily want the
user to be able to get at every page, just the right page at the right
time.
Right now, I would suggest creating a template that creates a
navigation structure, with links to learning objects created using the
existing templates. Then you can separate the navigation from the
content - a good thing in my view.
If I understand you correctly this is seeking to create
something akin to a contents page in a book, where you could have
chapter headings and sections within chapters, each section of which
would link to a learning object created in Toolkits (or Xerte). I agree
this separates the navigation from the content. This also facilitates
the re-use of content. A learning object that shows how to crack an egg,
can be included in separate courses on how to make pancakes and how to
make a victoria sponge (high level courses these!). It doesn't resolve
the situation in which the navigation is a core part of the learning
experience.
I remember a Chess tutor book by Lasker that worked that way. It
explained a concept then gave you a game problem to solve, after which
you were given a number of possible responses. Depending on the response
you chose you were directed to a different page of the book. Correct
responses lead you to an explanation of why the response was correct and
to the next concept. Incorrect responses lead you to a page that
explained why your solution would not work and then redirected you back
to the problem.
You can remove the various controls as you need - you just need
to know how to get at them from your code.
Is this a trade secret or would you like to reveal more :-)
I know the code I need to support a back button and a home
button. How feasible would it be to add them to the desktop Xerte
interface as additional options? How could this be done?
Kind regards

Hmm. Many questions. When things start getting non-linear it
becomes very easy for someone less skilled to create a real dogs dinner,
and there are many interface considerations: to ensure the user knows
where they are in relation to the rest of the content; that they can
easily get to the other bits; and that they know what else the learning
object contains and don't miss bits; and that they can easily return to
points of interest they've visted before.
I think there are probably two types of interface that would
suit toolkits; the linear one we have now; and a tree based structure
where the user drills down into the content, which could be n levels
deep. How the user navigates this is possible in many ways (a tree-based
TOC, or menu pages, or by answering MCQs or... well, you see the
problem. How to do it?
Right now, I would suggest creating a template that creates a
navigation structure, with links to learning objects created using the
existing templates. Then you can separate the navigation from the
content - a good thing in my view.

There are probably many Xerte users out there who do not have
access to Flash or lack skills in using Flash. They also lack
actionscript skills. The whole idea of page templates appears to be to
make things easy for the none technical user.
How about if the navigation could become more flexible so as to
allow none technical users the facility to customise their navigation
options, both in Xerte and in Xerte using project wide templates?
At present the navigation options in Xerte out of the box are
limited, kind of an all (visuals =1) or nothing (visuals = 0)
I am just finalising a page wizard that includes the capability
to add individual exit points i.e. in this case radio buttons, each of
which has a page name assigned to it in the wizard. When the learner
clicks on the radio button they are taken to the assigned page - instant
non-linear learning objects. However with the current navigation options
I have had to turn off visuals. Previous and Next buttons have little
sense in a non-linear learning object. However what are really useful
are Home and Back buttons (Back based on a LIFO queue). So to support my
wizard I have had to create a model based on an Entry Frame, that
provides user switchable navigation components (Page n of m, Home, Next,
Previous, Back, TOC, Last). The learning object creator can thus select
which navigation options are appropriate to their learning object.
If the navigation in Xerte could be set as configurable on a per
button basis, and include the volume control and also buttons for Home
and Back (I am not sure of the case for a Last button, I added it to my
model for completeness), then there would be no issue of the design of
the volume control failing to match the other controls in a custom
navigation.
The next step would be to add options to page templates that
would allow as many individual page templates as possible to have one or
more of their own specified exit points which each lead to a specified
page based on the page name.
If a similar customisable navigation were added to the simple
navigation available in Frameworks then just think of the possibilities,
e.g. a linear learning object with non linear sections based on
Framework pages; Whole learning objects that had a non-linear structure;
Non-linear learning objects with some framework based sections that were
linear.
What do others think?

If you are using a custom interface, then it won't likely 'fit
in' will it? We use a custom interface and have coded our own volume
control.

Subject: RE: [Xerte] Interface Volume Control
If there are a number of sound or movie files with different
audio levels then having one global sound control will not solve the
problem of having to adjust the sound each time you play one of the
movies. I don't know whether there is any way to pass a parameter to the
swf that plays the movies to adjust the initial sound level either
louder than default or lower than a default volume, though that could
get complicated.
It would be useful to have a volume control, but if it becomes
part of the controls displayed when visual is set to 1 on the interface,
then anyone not using the default interface will have to also introduce
a volume control into their interface.
If the volume control could become part of the media control bar
that is displayed when a movie or sound file is played, then this would
ensure that it was available even when the default interface was not
used. The snag here is that it would not be available for swfs where
Interactivity was set to Native swf.
Perhaps the optimum solution would be to include the volume
control in the default interface, but to provide an easy way to embed
the volume control into any custom interface that was being used when
interface.visuals = 0.

Could it go in the bottom toolbar, between the combos and the
continue button? I could remove the text from the continue button, to
make some space and replace it with a tooltip, and then put a volume
slider in there? Does that work?
Do people use the continue button, or the next button in the top
right more? I think the continue button is in a very logical place in
the bottom left, but I tend to use the next button. The continue button
will lose something if it gets too cramped with the other controls I
think.
Not sure where else the volume control could logically go? I'm
not sure I want to interfere with the standard media controller too much
- I'd prefer one control for global sound control..?

Is it possible to add a volume control to the interface
(preferable) or
movie or sound icons. I havew a few movies and the audio volume
varies.
