# Isabella Hong – Project 10

For my project this week, I decided to have my generative landscape be a sky with various sized stars. The stars are continuously generated and disappear at the end of the canvas in various sizes.

var rst = random(width);
stars[i] = makeStars(rst);
}

var starsToKeep = [];
for (var i = 0; i < stars.length; i++){
if (stars[i].x + stars[i].breadth > 0) {
starsToKeep.push(stars[i]);
}
}
stars = starsToKeep; // remember the remaining stars
}

// With a very tiny probability, add a new star to the end.
var newStarProbability = 0.05;
if (random(0, 1) < newStarProbability) {
stars.push(makeStars(width));
}
