```I'd do it by holding an array of coordinates, and looping through that using the interaction icon to trap the completes, incrementing your index, and re-animating

Trying to solve that posters animation issue.

A loop would have been handy.
Animate to
next page
Animate fro
loop.

It's trying to demonstrate say, Brownian motion of atoms.
So a couple hundred individual drawn items being animated.

So what's the easy way I'm blind to?

"No, if you have 10 children and repeat is 3, you will loop through three children and then exit, not 10 children three times and then exit,"

We have a semantic difference.
I don't see showing icon 1 then 2 then 3 as "looping"
I see passing through the decision icon and repeating the above as looping.
At least, that is how AW functioned.

I'm sure I did this in the past.
But maybe I was in a fever?
It's like distant ship's smoke on the horizon.

Not sure. It works the way it has for the last 5 years though. Maybe the loops were done by creating the children dynamically protoPage style?

So it does differ from AW then?
And then RepCount is a different var as well then?

I am positive I have had it operate a s a looping structure in the past.

Hi Jonathan.
Thanks for looking in to that.

The issue is that in Authorware, which Julian based the flow structure of Xerte on, setting a decision icons repeat property meant it would loop through that decision icon and all attached icons that specified number of times.

It would essentially repeat the entire attached sequence of icons x times.

I know I had this issue a couple years back, and the solution was a bit obtuse, but I can't remember it or track it down in the archives.

Dave

Further to my earlier post the Branch property will also affect what happens.

A setting of 'sequence', 'randomUnused', 'randomAny', or 'calculate'.

'sequence' loops through the children of the decision icon in order.

'randomUnused' loops through the children in a random order, until all the paths are used, or until the repeat property is satisfied.

'randomAny' loops through the children until the repeat property is satisfied, and may visit the same child more than once.

'calculate' allows you to route the flow into a particular page of the decision icon using the path property, which is zero based - to flow into the third page, set branch to calculate, and the path property to 2.

The following models use the decision icon and may give further insight into its use.
annotatedDiagram.rlm
bullets.rlm
buttonSequence.rlm
categories.rlm
columnPage.rlm
customHotspots.rlm
dialog.rlm
dragDropLabel.rlm
inventory.rlm
list.rlm
memory.rlm
perspectives.rlm
quiz.rlm
table.rlm
text.rlm
textMatch.rlm
thumbnailViewer.rlm
timeline.rlm

The only one that does not set repeat-"all" in the model code is text.rlm which has repeat="1" and branch="calculate"

Hope it does :-)

I have taken a look at the model files to see which pages use the decision icon.

After finding that the bullets page uses the decision icon I then ran some tests

By default the decision icon in the bullets page is set to

all

This results in the page listing every bullet.

If however you replace the repeat value in the property page with a number e.g.

3

Then only the first three bullets gets listed.

So I guess the answer is you put a number in (without any quotes) and the decision icon will run that many times.

Hope that helps.

You may find that taking a look at the bullets.rlm file in your xerte installs \pages\models\ folder will cast some light on its use.

Kind regards

Johnathan

PS sorry for the delay in replying - very busy on the Connector page documentation at the moment.

No takers?

Help says the Repeat property will take All or a number.
If I use a number, nothing happens.

What goes in the property sheet of a decision icon to have it repeat a set number of times?
