ofxMultiTouchActionsExample: problems. OF and Multitouch.

Hi all,

i am trying to make my own MT apps into OF.
I followed the good ofxMultiTouchActionsExample (http://code.google.com/p/smallfly/downloads/list).
I have some errors: the buttons do not deal with the input data and neither the functions (background change with slider movements).
With markers, everything is good.

Here some code:

in testApp.cpp:

  
...  
button.registerForMultitouchEvents();  
....  
....  
bSlider.setPriorityLevel(3);  
	bSlider.registerForMultitouchEvents();  
	  
	tRange = new int[1];  
	tRange[0] = 1;  
	bSlider.setIsDraggable(true, tRange, 1, false, true);  
	delete [] tRange;  
	//----------------  
	  
	  
	mtActionsHub.addObject(&draggableRotatableScalableItem);  
	mtActionsHub.addObject(&scalableItem);  
	mtActionsHub.addObject(&draggableItem);  
	  
	mtSliderHub.addObject(&rSlider);  
	mtSliderHub.addObject(&gSlider);  
	mtSliderHub.addObject(&bSlider);  
	  
	  
	ofAddListener(rSlider.eMultiTouchMoved,this,&testApp::updateBackgroundColor);  
	ofAddListener(gSlider.eMultiTouchMoved,this,&testApp::updateBackgroundColor);  
	ofAddListener(bSlider.eMultiTouchMoved,this,&testApp::updateBackgroundColor);  
	  
	//add button event listener for global callback function in testApp  
	ofAddListener(buttonTwo.eMultiTouchUp,this,&testApp::buttonTwoCallback);  
	//ofAddListener(button.eMultiTouchUp,this,&testApp::buttonTwoCallback);  
  
....  
....  
void testApp::tuioObjectAdded(TuioObject & tobj){  
	cout << " object added: " + ofToString(tobj.getSymbolID())+  
	" X: "+ofToString(tobj.getX())+  
	" Y: "+ofToString(tobj.getY())+  
	" angle: "+ofToString(tobj.getAngleDegrees())  
	<< endl;  
	  
	//forward the marker events to ofxMarker for the InteractiveObjects  
	ofxMarker.markerDown(tobj.getSymbolID(), tobj.getX(), tobj.getY(), tobj.getAngleDegrees());  
}  
  
  
void testApp::tuioCursorAdded(TuioCursor & tcur){  
	cout << " cursor added: " + ofToString(tcur.getCursorID())+  
	" X: "+ofToString(tcur.getX())+  
	" Y: "+ofToString(tcur.getY())  
	<< endl;  
	  
	ofxMultiTouchCustomDataSF multiTouchCustomData;  
	multiTouchCustomData.sessionID = tcur.getSessionID();  
	  
	mtActionsHub.touchDown(tcur.getX(), tcur.getY(), tcur.getCursorID(), &multiTouchCustomData);  
	mtSliderHub.touchDown(tcur.getX(), tcur.getY(), tcur.getCursorID(), &multiTouchCustomData);  
	  
	/*  
	draggableRotatableScalableItem.touchDown(tcur.getX(), tcur.getY(), tcur.getCursorID(), &multiTouchCustomData);  
	if(draggableRotatableScalableItem.ownTouchCursor(tcur.getSessionID())) {  
		return;  
	}  
	*/  
	  
	//forward the touch events to ofxMultiTouch for the InteractiveObjects  
	ofxMultiTouch.touchDown(tcur.getX(), tcur.getY(), tcur.getCursorID(), &multiTouchCustomData);  
  
}  
  
  

Seems that ofxMultitouch.touchDown is not forwarding that to the buttons…
It works with ofxMarker.markerDown(tobj.getSymbolID(), tobj.getX(), tobj.getY(), tobj.getAngleDegrees());.

Any ideas?

Arent we mixing old .touchDown with the new built in .touchDown?

And the main point:

How to do a interactive button, etc. In OF 0.07, using built in events?
How to make in listen to touchDown?
How to pass tuio messages to events?

Any tutorial about MT in OF would be great. Once i understand that i will make one !

thank you,

miguel.

hey - just posted this on another thread but I recently looked into this to get a 3M screen working on osx with this tuio server:

some working OF 007 examples for xcode:

HI,

thank you so much. The examples work now perfectly :-).
Because i could not make them work, i just made a new class copying “ofMarkerObject” but with touches and it worked. So I learned. But it is really good to have the “original” code working now…

So i am getting ready to go to Multitouch OF !

by the way, it is allways an excelent idea to give examples with the addons included, as you did. Thank you.
