Hi all, I have this little script running on a page:

var blink = widget("Michrophone");
var i1 = 2;
blink.visible = true;
Activity.scheduleAfter(1000,UpdateTimer1);
function UpdateTimer1(id)
{
i1--;
if (i1>0)
{
Activity.scheduleAfter(1000,UpdateTimer1);
blink.visible = false;
}
else
{
blink.visible = true;
}
}


The idea is to have the Widget "Microphone" to flash… Now this script only do as follow: show - not show – show… and then it stops. How can I make it continue to flash for some X seconds?

Allan,

Did you try increasing the value of the i1 variable to something larger than 2?

If you have, then I must be misunderstanding what you want. You could also use 2 variables, one to track flash on/off state and one to track timing. That is indeed more complex and your script above is already overkill.

For example, your lines
blink.visible = (where you specify true or false);
could be replaced with
blink.visible = !(i1 % 2)

Hi again,

That I need is a widget to blink/flash to attract attention to the user.. If I increase the i1 value the “not visible” state will just be on for more second before ELSE kick in -and thus the visible state. I might be doing some overkill here – I’m not a programmer :-) just having some fun with my TSU9400…

That I would like is that the widget should flash som 10 times, while NOT looking the GUI, and then after some time a Page jump to HOME.

Here is a solution: I will also post is as a utility for general use, when I made it proper for that use.
I've put this in the activity script. You can check what's happening in ProntoScript console.

function blink(blinkData) {
System.print(blinkData[0]+" "+ blinkData[1]+" "+blinkData[2])
System.print(blinkData[1]%2);

widget(blinkData[0]).visible=(blinkData[1]%2) ? true:false;

if (blinkData[1] > 0) {
blinkData[1]--;
Activity.scheduleAfter(blinkData[2], blink, blinkData);}
}

blink([ "M", 10, 333]) // resp tag, blinkQty, frequency

Hi Rusty.. It works beautifully!

This stuff looks like a real piece of programming - not like my humble attempt. Many thanks!

Hi Allen, thanks,
here is the version that I will post as utility.
Rusty

function blink(blinkData) {
// makes a widget blink for a given number of times at a given frequency
// blinkData = [widgetTag, blinkQty, blinkFrequency]
this.widgetTag=blinkData[0];
this.blinkQty=blinkData[1];
this.blinkFrequency=blinkData[2];

widget(widgetTag).visible=(blinkQty%2) ? true:false;

if (blinkQty > 0) {
blinkQty--;
Activity.scheduleAfter(blinkFrequency, blink, blinkData);}

It makes sense to me, at least the description / instruction, so I think others could use it easily,.
