Processing Particle
问题 I've been trying to do something with this project I have but failed always so far :) so decided to ask here :) I want the particles to go around the ellipse from Rock class, not through it but around it, like a rock inside a river that water flows around it. Any suggestions ? int NUM_PARTICLES = 1000; ParticleSystem p; Rock r; void setup() { smooth(); fullScreen(P2D); //size(700,700,P2D); //background(0); p = new ParticleSystem(); r = new Rock(); } void draw() { background(0); p.update(); p
