Inspiration

Having learned objects and arrays, I felt really want to do something great. I got Inspired by fireworks and Yiting Liu’s great homework and decided to create my own version of shooting stars.

Since last time it got really slow when I draw a lot of flowers, I decided to create my own png files instead of drawing directly by p5, and it turned out to be really good with transparency.

I created a single star in Illustrator and leave some transparency by the help of PNG.

 

I started like creating a lot of not bouncing balls and it seemed appealing.Screen Shot 2015-10-07 at 1.39.00 AM

Then I made them each rotating with different speed, and the faster it falls, the faster it rotates.

I also made it appear within a range of the location of cursor, instead of simply appear at where you point to. It is changeable by scrolling up and down and a circle will appear shortly if some change is made.

A last good feature is that when you click at some point, then it will automatically be a source of stars and no need to wave anymore, just relax and enjoy 😀

Play together is also full of fun~
