8 years ago Hi, it seems that you sketch is missing part of the code, you should have the definition of the class Planet somewhere, either down below in the main sketch code, or on a separate tab.

when i run this code i get this part of the code highlighted why? Planet[] planets = new Planet[10];
/**
*
*/
import codeanticode.planetarium.*;
// A bunch of planets Planet[] planets = new Planet[10]; // One sun (note sun is not attracted to planets (violation of Newton's 3rd Law) Sun s;
// An angle to rotate around the scene float angle = 0;
void setup() { size(800, 800, Dome.RENDERER); smooth(); // Some random planets for (int i = 0; i < planets.length; i++) { planets[i] = new Planet(random(0.1, 2), random(-width/2, width/2), random(-height/2, height/2), random(-100, 100)); } // A single sun s = new Sun(); }
void pre() { for (int i = 0; i < planets.length; i++) { // Sun attracts Planets PVector force = s.attract(planets[i]); planets[i].applyForce(force); // Update and draw Planets planets[i].update(); }
}
void draw() { background(0);
// Setup the scene lights();
translate(width/2, height/2, 300);
rotateY(angle);
// Display the Sun s.display();
// All the Planets for (int i = 0; i < planets.length; i++) { planets[i].display(); } }
// Called after rendering all the faces, but before the dome sphere, // so it can be used to draw stuff on the corners of the screen. void border() { perspective(); camera(); background(255); fill(0); text("FPS: " + frameRate, 20, 20); }
void post() { // Rotate around the scene angle += 0.003; }
