Draw Trees in One-Point Perspective with a Rainbow
Problem Statement:
Edit the function at the top so that it takes x, y, and s variables to draw a tree whenever called. The x and y coordinate determine the location, while s determine the size of the tree.
/* Code generated by RoboBlockly v2.0 */
#include <chplot.h>
CPlot plot;

// draw trees scaled
void drawTree(double x, double y, double s) {
  double ytrunk;
  plot.fillColor("#006600");
  plot.regularPolygon(x, y, 3, s, 0);
  ytrunk = y - double(s)/(2 * sqrt(3));
  plot.fillColor("#663300");
  plot.rectangle(x - double(s)/12, ytrunk - double(s)/3, double(s)/6, double(s)/3);
