Fade out Effects

• • Watch Fun Programming [video 22]

  • Here’s a program I wrote:

float x_value;

void setup()

{

size(400,200);

background(0);

stroke(255);

frameRate(2);

noFill();

}

void draw()

{

x_value = (x_value+61) % 400;

rect(x_value, 100, 50, 50);

}

• • Change the program so the old rectangle fades away as you draw new ones
