the Stage Mouse Watcher is basically taking data from the mouse position (0 through 100 as a percentage of the distance across the stage) and outputting it as a number between 0 and 100. So processing the output of this has the same effect as processing the input. Ryan's patch does exactly what you need it to do and has the same effect as changing the Limits of the input to the Actor - setting a minimum and maximum range for the mouse position, and outputting the results as a number between 0 and 100. you would just need to do the same for the vertical position.

Hi there, 

Could you show us what kind of Cue list you build ? If you have that, we can help you further :)

@lauri

I wrote the attached user actor  a few months  ago to provide an ongoing average FPS calculated from the most recent 100 samples, but it can be used for any stream of numbers. You are welcome to use it.

Don

you're welcome. i use the Video Fader into Multimix combination regularly - often linked directly to the slider channels of a Korg NanoKontrol. the slightly confusing thing about it is that at zero it lets the video stream through, but at 100 its fully faded across to the background colour, so i tend to swap the MIN and MAX values so it works more like a hardware mixer.

When all of my macs site untouched for 15sec or more then I trigger an audio sound effect it is late. If the mac stays active the sound effect is accurate.

@craigw you are welcome !!

Best,

Maxi

Great, thanks for the help I really appreciate it. I'll have a look into both options and post an update with my results :)

Hi,

Michel and Jurrian have indicated the elements within Isadora that are activated directly by the input of code statements. There are a couple of other elements that require code like configurations, although they do not involve complete code statements. For example configuring network and system settings such as IP, Artnet, Serial Port, Open Sound Control e.t.c

Additionally, I have found that many productions involve system interfaces that require coding in other software that Isadora plays with. For example, Processing and Arduino/microcontoller are great companion programs that require direct coding to work with Isadora.

So in my mind although Isadora is a node based visual programming environment, the integration of it into a broader system of production, at times, requires elements of code.

Best wishes

For triggering videos with the arrow button you have to use the "keyboard watcher" actor. Assign the arrow key to the right to add 1 to the float counter and the arrow key to the left to subtract 1 to the float counter. This way you can cycle through your videos. To assign the arrow keys to the "keyboard watcher" actor click into the black field of the "key range" input. Type a single quotation mark (') on the keyboard, then click on the right arrow and again a single quotation mark ('). Do the same on a second Keyboard watcher for the left arrow. You will see an empty space between the quotation marks, but thats fine.

@skulpture

OK.

But since the scene must be activated, it needs a full processing even if the framerate is lowered? Am I Wrong?

Or is it possible to view this preview without activating the scene itself? 

@mark_m

Yep seems to me thats true.

Best Michel

if you are only playing one image at a time, you can automate the system with one Note On Watcher - you need to load a series of image files into your bin and change the reference number in the Picture Player. The Limit-Scale Value actor is for assigning the range of keys to the range of images. 

Thanks all!

What graphics card does your student have? Usually it is a matter of what version of OpenGL is supported by the graphics card, and not a library that needs to be loaded.
Installing the latest graphics card driver, may help.

@helendeneb

since you want to be able to have the previous state remain.. (do you want all to remain as you move thru them?)
I would consider doing the whole cactus portion of the show in 1 isadora scene. That makes displaying them all together very easy.
I would build each Cactus bloom series as a User Actor, with trigger controls and Media IDs as inputs.
Once you have 1 working.. you can add copies of the user actor, change the Media IDs, and you have now multiple sequences that can be triggered how ever you like.
This isn't the most beginner thing to do.. but User Actors are one of the most power pieces of Isadora so learning them early is a great idea.
I don't know exactly how you want things to work, or what media you are using.. but I think its an achievable goal.

If you can supply details on how you plan to structure the media.. I would be happy to make a demo file with a User actor explaining the method I described.
@dbini 's idea of laying the blooms over the background cactus sounds very good. So in that case, the Cactus, would be placed out side any user actor, and the blooms would overlay with alpha channels.

@skulpture

right.. tap tempo will help smooth out any change in BPM.
You could also add a 'Smoother' actor to make abrupt changes have a transition.

@HelenDeneb 

look at this post to see how it works: https://support.troikatronix.c...

i don't have isadora now with me to give it a try but maybe try to put the activate scene actor inside the scene you want to activate. So when you press the letter for the scene you want live, it will stay activated.

@bonemap

I think you and I are playing around with similar (but different) types of things these days.
I'm feeding xyz values (as Json) all over currently, and was about to look for a way to extract them from geometry, so pointing me at Meshlab is great, thanks.
