Hello

Try this

float value = 0;

void setup()
{ 
 size(1000, 600);
}

void draw() {

}

void keyPressed() {
  value+=0.1;
  if(value >=6.28){
     value=0;
  }
  else
  {
    arc(mouseX, mouseY, 80, 80, 0, value,PIE);
  }
}

Can you be more specific? To draw an arc, you need a bunch of parameters-

• Firstly, what do you want as the centre of the arc? It seems like you want is the the mouse position.
• Secondly, what angle should is sweep? You haven't specified it.
• Lastly, what should its size be? Is seems like you want a circular arc with radius same as distance b/w centre of screen and mouse position.
