I would like to introduce a new "if" like object. you can call it when. lets say i have a sketch using a live input. i want a shape to be permanently replaced when the input variable reaches 50. if you use the "if" it will only change while the input is over 50 but i want the shape to stay changed when the variable decreases and goes under 50.

instead of having some stupid variable increment every time it is over 50 and then have the shape change if the variable = 1, one could use this function. or do you have some other way of doing that?

The only way to do what you want is to store some state I'm afraid, and it's very unlikely that any new flow-control statements will be added, since processing just maps them directly into the Java versions.

So you're just going to have to keep a boolean or something aroundto check to see if the value has ever passed 50.

e.g.
Code:
boolean over50=false

//...

if(inputValue>50)
{
  over50=true; 
  //set to true, and if never set to false, it will stay true forever.
}

if(over50)
{
  doA();
}
else
{
  doB();
}
