Nice idea on the button! I never think to stack widgets like that, although you can actually stack them as "high" as you want. Unfortunately the button idea only works for one touch, but the next update of Control will have an extra scripting goody to handle multiple touches. I added a parameter called "lastTouched" that always refers to the most recently processed touch event. So you can get the id of the touch in a ontouchstart as follows:

"ontouchstart":"oscManager.sendOSC('/multi/' + this.lastTouched.id, 'f', 0);"

I thought I had something like this in there previously, but I must be confusing it with something else... can't find a trace of it.

My way to solve this problem was to put a button just underneath the widget with exactly the same size. if you give that one a different color you also get multicolored parameter feedback....WHOA!! ;-)

Charlie, thanks for the precious help! That worked! :-)

"ontouchend": "oscManager.sendOSC('/multi/0', 'f', 0);"

First, you need to include the typetags for the message. This tells the network protocol what type of data is being sent. In this case we're sending a floating point number ( 0 ).

For the multitouch widget, the touch number is appended to the address of the widget as opposed to being a message argument. You can, of course, send whatever message you want if you don't like this behavior. Thus, the line I wrote above is roughly equivalent to:

"ontouchend": "oscManager.sendOSC('/multi', 'ff', 0, 0);"

... where the first 0 would be the touch number instead of including it in the address. Hope this helps! - Charlie

"ontouchend": "multi1.setValue(0,0)",

? :-)

Or this...

"ontouchend": "oscManager.sendOSC("/192.168.1.78:1000","multi1", 0, 0)",

from the ste example: oscManager.sendOSC("/someOSCaddress", "if", 0, 2.2);

Cheers!

Ok, I just realized there's a ontouchend property.
Shouldn't this work?

"ontouchend": "oscManager.sendOSC("multi1", 0, 0)",

so that I can send 0's once I lift my finger?

Thanks in advance!

Hi there! New to Control and starting my exploration! :-)
I would like to know if there is any kind of property for MultiTouchXY so that I can receive a message to know if I pressed (or depressed) the that widget? Meaning: it seems I can receive xy messages only when moving about the surface. I would be cool to know when a finger has been lifted (for ex. for sending velocity zero to a pending midi note). Is this possible in any way or with any workaround?

Thanks!
