hi there, i'm trying to make a program to create objects and then actively make an ellipse which is the average of the x and y positions of the objects. the idea is to use it to make an average of peoples' houses on a map and then find the best place to meet for everyone. here's what i've got so far but i can't work out how to get the average of the x and y positions in the arraylist
- class House {
float x;
float y;
float r = 10;
boolean move; - public House() {
x = random(width);
y = random(height);
} - public House(float sx, float sy) {
x = sx;
y = sy;
} - void display() {
fill(255);
ellipseMode(CENTER);
ellipse(x,y,r,r);
} - void moveon() {
if(mousePressed && dist(x,y,mouseX,mouseY) < 10) {
move = true;
}
else {
move = false;
} - if(move) {
x = mouseX;
y = mouseY;
}
}
} - ArrayList houses;
- void setup() {
size(800,600); - houses = new ArrayList();
} - void draw() {
background(100); - for(int i=0; i<houses.size(); i++) {
House h = (House)houses.get(i);
h.display();
h.moveon();
h.moveon();
} - average();
} - void keyPressed() {
if(key == 'h') {
houses.add(new House(mouseX,mouseY));
}
} - void average() {
for(int i=0; i<houses.size(); i++) {
House h = (House)houses.get(i); - float ax = h.x(i) + h.x(j);
float ay = h.y/houses.size(); - ellipse(ax,ay,10,10);
}
}
-
any ideas?
