Getting Started

client

1. include "ofxTuio.h" and instance the class

#include "ofxTuio.h"

class ofApp : public ofBaseApp{

	void setup();
	void update();
	void draw();


	//event notify classes
	void tuioAdded(ofxTuioCursor & tuioCursor);
	void tuioRemoved(ofxTuioCursor & tuioCursor);
	void tuioUpdated(ofxTuioCursor & tuioCursor);

	ofxTuioReceiver tuio;

2. setup connect port and notify events

//set up port and chose protocol
tuio.setup(new ofxTuioUdpReceiver(3333));
//or tcp...
//tuio.setup(new ofxTuioTcpReceiver(3333));

//add event listener
ofAddListener(tuio.AddTuioCursor, this, &ofApp::tuioAdded);
ofAddListener(tuio.UpdateTuioCursor, this, &ofApp::tuioUpdated);
ofAddListener(tuio.RemoveTuioCursor, this, &ofApp::tuioRemoved);

//connect
tuio.connect();

server

1. include "ofxTuio.h" and instance the class

#include "ofxTuio.h"

class ofApp : public ofBaseApp{

	void setup();
	void update();
	void draw();

	ofxTuioSender tuio;

	//mouse click flag for just this example
	bool isPress = false;

2. setup protocol. address and port.

//setup address, port and server name. basically it is UDP protocol.
tuio.setup(new ofxTuioOscSender("127.0.0.1", 3333), "example");
//add protocol if you want
//tuio.addProtocol(new ofxTuioWebSocketSender(8080));
//tuio.addProtocol(new ofxTuioFlashSender());
//tuio.addProtocol(new ofxTuio::ofxTuioTcpSender(3333));

//auto calculate, fit to range 0.0 - 1.0. ofRectangle is screen size
tuio.setAutoFitRange(true, ofRectangle( 0, 0, 500, 500));

//starting position send
tuio.run();

3. adding object. Object is you want send position between begin() - end().

tuio.begin();
{

	float x = (float)ofGetMouseX(), y = (float)ofGetMouseY();
	bool mouse = ofGetMousePressed(0);

	//add object
	if(mouse && !isPress){
		isPress = true;
		tuio.addObject(x, y);
	}
	
	//update object
	if (isPress) tuio.updateObject(x, y);
	
	//remove object
	if (!mouse && isPress) {
		isPress = false;
		tuio.removeObject(x, y);
	}
}
tuio.end();
