touchToKill.activeNumber works!

Thanks again Charlie for you help!

Try using touchToKill.id. If that doesn't work, touchToKill.activeNumber might be what you need.

Charlie,

Thanks for the quick response. I'm relatively new to Control/Java/JSON so excuse me for my newbieness. Changing the wanted 'null' response to an int sends the message, however the OSC tag returns /multi/[object HTMLDivElement] ... What the correct syntax to return the tag of the removed touch (such as /multi/6)?

Thanks
Paul

For whatever reason it looks like I'm only support ints, floats and strings right now. Sorry about that... maybe I can look into supporting null, T and F for the upcoming v2. I guess just send a defined int (like -12345) instead of null in the meantime.

I am working on an interface that involves the use of the multiXY widget and I am trying to figure out how to send a 'null' message via OSC when a touch is removed. I have tried using the oscManager.sendOSC(); in both the window.removeTouch() function and within the widget itself with no luck. Any help would be appreciated.

window.removeTouch = function() {
	var multi = window.multi;
	var touchToKill = multi.children.pop();   /* remove last child and map to variable */
	multi.container.removeChild(touchToKill); /* remove from web renderer */
	oscManager.sendOSC('/multi/' + touchToKill, 'f', 'null');
}
