How can I code something like a normal on/off switcher?
I know now with the help of the kind people in this forum how to use the keys of my powerbook-keyboard, but I want to be able to use them like regular buttons. So when I push once the key 'a' then processing should do: blabla (A) and when I push it again it should do blabla (B) and then when I push it should do again the same like (A). I need this for communicating with SC3 via OSC.

void aaOscMessage() {
       OscMessage oscMsg = oscP5.newMsg("/windstop");
       oscP5.sendMsg(oscMsg);
}

void abOscMessage() {
       OscMessage oscMsg = oscP5.newMsg("/windstop");
       oscP5.sendMsg(oscMsg);
}

void keyPressed()
{
 switch(key){
 case 's':
// here I need something .... if u push it the first time do
aaOscMessage();
// if u push it the second time do
abOscMessage();
// set counter to Zero? So next time is again first time??
   break;
}
}

Here's a way of programming a key toggle function using keyPressed() and released().

Code:

void draw() {

if(pause) {return;}

else {
do stuff....
}

}

boolean pause = false;
boolean ptoggle = false;

void keyPressed() {

if(key == 'p' && !ptoggle) {pause=!pause; ptoggle=true;}

}

void keyReleased() {

if(key == 'p') {ptoggle=false;}
}

 

Switching background on and off, with keyreleased:
Code:

boolean showbg = false;

void draw()
{
 if(showbg) background(0);
 else background(255);
}

void keyReleased()
{
 switch(key){
 case ' ':
  if(showbg) showbg = false;
  else if(!showbg) showbg = true;
 break;
 }
}
 

off the top of my head, so might be some typos..
