A clear function?
« on: Nov 18th, 2003, 12:07am » |

here is my code:
void setup()
{
size(300,300);
}
void loop()
{
fill(205,205,0);
ellipseMode(CENTER_DIAMETER);
ellipse(mouseX,30,30,30);
}
now this works great and all but it 'lags' in otherwords it leaves a trail of the previous circle there, is there a way thati can clear that circle so that its only the one cirlce moving?
Thanks!
Mike

Check out the 'background()' method. Think that is what you need.

and if you want the older stuff to fade out, try drawing a rectangle with a very low alpha value like such:
Code: fill( 0 );
noStroke();
rect( 0, 0, width, height, 10 );

I think you meant to put the '10' in the fill method.
rect() takes four parameters, I think, unless this is an undocumented way to fill a rect.
fill(0, 10); will set the fill to black with an opacity of 10

hm, i wonder if we oughta change background() to clear() now that it has to be called explicitly.. though clear(BImage image) is a little weird..
