Animate a Shooting Star
Problem Statement:
The pre-placed blocks will animate the star moving horizontally across the screen. Add more blocks to show the trails behind the star. Edit the pre-placed blocks so the star falls in a parabolic path.
```/* Code generated by RoboBlockly v2.0 */
#include <chplot.h>
double i;
double yCount;
double yStar;
CPlot plot;

for(i = 12; i <= 36; i += 0.8) {
yCount = i - 11;
yStar = 34 - (yCount * yCount) * 0.07;
//plot.backgroundImage("crescentMoon.png");
plot.strokeColor("#ffff66");
plot.fillColor("#ffff66");
plot.star(i, yStar, 3, 0);
plot.arc(i - 4, yStar - 4, 5, 45, 150);
