Sketch Priority ?

pxgator

Is there a way to give a sketch a higher priority ?

In what sense?

I'm running processing on a Raspberry Pi 2 with debian jessie which allows executables to have higher thread prioritys. Just wondering if it's possible to give a sketch a higher priority with my setup.

The code on this webpage should help.

The code seems to just create a separate thread but it does not change the sketch thread priority.

I am afraid your last statement is wrong, no new thread is being created and in a Processing sketch Thread.currentThread(); returns the Animation Thread.

I created the sketch below from the code from my link.

Use the + and - keys to change the Animation Thread priority between 1 and 10 inclusive, it starts at 5.

void setup() {
  size(300, 300);
  fill(0);
}

void draw() {
  background(255);
  Thread t = Thread.currentThread();
  text(t.getName() + "  : priority = " + t.getPriority(), 20, 30);
}

void keyTyped() {
  if (key == '+' || key == '-') {
    int delta = (key == '+') ? 1 : -1;
    Thread t = Thread.currentThread();
    int priority = t.getPriority();
    int newPriority = constrain(priority + delta, 1, 10);
    if (newPriority != priority) 
      t.setPriority(newPriority);
  }
}

Thank you for the information Sir. This does work.:)
