Assignment 11

for this I tried to go off what we did last class and delete a ball i tried using array.pop() and array.splice() but I couldn't get it to work and for the final project I want to make the space invaders game or an asteroids game.

var bXloc =[];

var bYloc = [];

var xSpeed = [];

var ySpeed = [];

var numB = 1;

function setup() {

// put setup code here

createCanvas(800, 500);

for(var i=0; i<numB; i++){

bXloc[i] = random(50, 700);

bYloc[i] = random(100, 400);

xSpeed[i] = random(-50, 50);

ySpeed[i] = random(-50, 50);

}

}

function draw() {

// put drawing code here

background(50);

for (var i=0; i<numB; i++){

fill('red');

ellipse(bXloc[i], bYloc[i], 20, 20);

}

for (var i=0; i<numB; i++){

bXloc[i] = bXloc[i] + xSpeed[i];

bYloc[i] = bYloc[i] + ySpeed[i];

//bXloc[i] += xSpeed[i];

//horizontal bounce

if ((bXloc[i] > 800) || (bXloc[i] < 0)){

xSpeed[i] = -xSpeed[i];

}

//vertical bounce

if ((bYloc[i] > 500) || (bYloc[i] < 0)){

ySpeed[i] = -ySpeed[i];

}

}

}

function mousePressed(){

numB = numB + 1;

bXloc.push(mouseX);

bYloc.push(mouseY);

xSpeed.push(random(-5, 5));

ySpeed.push(random(-5, 5));

}

function KeyPressed(){

if(key==='q'){

bXloc.splice(0,1);

bYloc.splice(0,1);

xSpeed.splice(0,1);

ySpeed.splice(0,1);

}

}
