The JS actor does not have any drawing abilities. It can create streams of numbers for animation, that you would feed to a Shapes actor or Lines actor. But can't create polygons directly.

We'd love it if you could upload this to the Add-Ons page if you haven't already <3

@dusx This is amazing and super helpful. Thanks!

@dusx

Looks interesting! will try it out soon. Thanks for sharing!

You may also want to find a monospace font to use, this way you can calculate the space required for the word, since each letter will take up equal space. That should allow for a grid like layout to become possible. Rotation will be another monster.

Great. Flawless. Exactly what I meant.

Thanks! Peter

feedback that it's working

 Hi,

Brilliant! 

I will do some testing exchanging json files on the fly and see how that then propagates throughout a patch.

We'd love it if you could put this workaround on the TroikaTronix Add-Ons page (link in my signature) :)

Best wishes,

Woland

Here's an example patch. Using the Edit Text Control on the left, enter the list of items, each one on a new line. Then type a few characters in the center Edit Text Control. The Javascript actor will do a case-insensitive search and show the resulting list of items in the text box on the right.

 Is this already on the Addons page?

@peuclid

To close this issue. I went ahead using broadcasters/listeners in User Actors and it feels cleaner now and less prone to misconnecting hundreds of lines. Thanks for the advice!

@woland

Thanks. I'll add to the plug-ins, probably this weekend. I'll want to make a little how-to video since it might not be obvious how to use it.

Also, since I built upon the work shared by @frank522 in his showcase, I'll want to share how simple it is to make scenes from zoom participants. I'm excited about it.

Workable for now, but indeed it becomes a bit stupid when we have a greater range.

 Yeah...

The range data type is really weird and a pain in the but to try to change dynamically.

If you need something much more true to the laws of physics, you can look at this demo:

The DEMO FILE is zipped with the required Javascript files (all reside in the same folder).
I have included a number of resource URLs in the JS code, that will be helpful in figuring out how this works.

Hi,

In the lockdown, I set myself a challenge to gain some understanding of using data sources available online to create a 'data-driven' Isadora patch. There is a lot of online data available; some are 'open access' and some require an access key or subscription. I have put together a demonstration patch that uses data from multiple open access (non-subscription) sources. They are The World Bank and VirusTracker. [EDIT] VirusTracker API appears to be no longer functional, therefore COVID-19 data is no longer updating in the patch download.

In creating the demo patch, I have learnt how to use the Text Formatter module to modify the request URL that gets sent to an API data source. It allows for data with different content to be updated based on dynamically changing identifiers in the request URL. For example, comparative information about a specific country requested through a 'country code' of only two characters. The VirusTracker API returns data about individual countries and the statistics associated with the current COVID19 pandemic. The virus data is updated daily. A date format identifies requested statistics from a specific day within the pandemic period. Combining the country code and the date format dynamically in a request URL patched to the Get URL Text modules returns statistics that are then available for display in the Isadora Stage. By automating the construction of the URL that identifies the dataset requested from the API, the data on the Isadora stage transforms into a dynamic representation of changing datasets.

The success of this learning development is due to the release of new Beta tools made available by @mark and the wisdom of the Guru sessions. The 'JSON Parser Beta', and the three.js 'JS Convert Rotations' module have taken a lot of the pain out of doing this kind of work. "Tip of the hat" to Mark, using one of his expressions of gratitude.

Kind Regards

Russell

@jfg

Just so you all know: I've been hestitant to allow actors in Isadora that could allow a patch to do damage to your system, i.e., erase your hard drive. That's why I've avoided things like allowing AppleScript or applications to be launched. To me it feels like a security risk to allow such things. But I am happy to see that the Isadora community always seems to find a way. ;-)

Best Wishes,
Mark

Just a quick add. I have tested with both using null and undefined in an attempt to have an output not trigger.
In both cases Isadora is converting these into false (zero) values. 

@salimelo said:

Hi everyone, hope you all are doing fine. Looking for a way to tell the Javascript Actor to send a trigger signal to its output if condition is true, and no signal at all, if condition is false. Any suggestions? THXaLot, kindly, JK

 Situaion solved, I falsy suggested outputting 0 would result in not sending a trigger signal. Instead, not outputting any value at all (I was using if and else) results in not sending a trigger signal either. (means: no else condition at all). THX

@woland wonderful info. THank you!

Thanks for your reply guys. I will experiment a bit with it!
