HW #24

[chasestarr]

In this homework we will practice using class inheritance. Use this week's exercise for help.

_Description:_ Just like last week, make your own project! The only requirement is to create at least 3 different variations of the particle object. Look at the example from this week for help.

Do they need to be removed? I seem to be having trouble with that aspect.

[The-Space-Core]

ParticleSystem ps;

void setup(){ size(800,1000);

ps = new ParticleSystem(new PVector(400,200)); } void draw(){

background(255);

ps.run(); ps.addParticle(); }

[The-Space-Core]

class Confetti extends Particle { color c; Confetti(PVector l){

super(l); c = color(random(255),random(255), 0); } void display(){ rectMode(CENTER); fill(255,255,0); stroke(0); rect(location.x,location.y,8,8); } }

[The-Space-Core]

class Face extends Particle{ Face(PVector l) { super(l); } void display(){ fill(255,0,0); ellipse(location.x,location.y,5,5); } }

[The-Space-Core]

class Particle{ PVector location; PVector velocity; PVector acceleration; int lifespan;

Particle(PVector l){ acceleration = new PVector(0, 0.05); velocity = new PVector(random(-2, 2), random(-6, 0)); location = l.get(); lifespan = 255; }

void run(){ update(); display(); }

void update(){ velocity.add(acceleration); location.add(velocity); lifespan -= 1; }

void display(){ stroke(lifespan); fill(175,lifespan); ellipse(location.x, location.y, 8, 8); } void applyForce(PVector force){ acceleration.add(force); } boolean isDead(){ if(lifespan>0){ return false; }else{ return true; } }

}

[The-Space-Core]

class ParticleSystem{ ArrayList particles; PVector origin; //ArrayList plist; ParticleSystem(PVector location){ origin = location.get(); particles = new ArrayList(); }

void addParticle(){ float r = random(1); println(r); if(r < 0.5){ particles.add(new Face(origin)); } else { particles.add(new Confetti(origin)); } }

void run(){ for(int i = 0; i < particles.size(); i++){ Particle p = particles.get(i);

p.run(); if (p.isDead()){ println("rent in panama"); particles.remove(i); }

} } }

@brandonsugar you do not need to delete the objects
