I decided to start learning javascript & made a flappy bird, but after adding the pipes my screen was white. I’m using notepad ++ javascript
here the html
```auto
Testing
```
here bird.js
```auto
function Bird(){
this.y = height/2;
this.x = 50;
this.grav = 0.6;
this.vel = 0;
this.lift = -15;
this.show = function() {
fill(255);
ellipse(this.x,this.y,32,32);
}
this.up = function(){
this.vel += this.lift;
}
this.move = function(){
this.vel += this.grav;
this.vel *= 0.9;
this.y += this.vel;
if (this.y > height) {
this.y = height;
this.vel = 0;
}
if (this.y < 0) {
this.y = 0;
this.vel = 0;
}
}
}
```
here sketch.js
```auto
var bird;
var pipes = [];
function setup(){
createCanvas(400,600);
bird = new Bird();
pipes.push(new Pipe());
}
function draw(){
background(0);
bird.show();
bird.move();
for (var i = 0; i < pipes.length; i++){
pipes[i].show();
pipes[i].update();
}
}
function keyPressed(){
if (key == ' '){
bird.up();
}
}
```
here pipes.js
```auto
function Pipe() {
this.top = random(height/2);
this.bottom = random(height / 2);
this.x = width;
this.w = 20;
this.speed = 1;
this.show = function(){
fill(255);
rect(this.x, 0, this.w, this.top);
rect(this.x, height-this.bottom, this.w, this.bottom);
}
this.update(){
this.x -= this.speed;
}
}
```
anyone know why I see a white screen instead of my game?

You have an error in your JS somewhere that’s crashing your sketch.
Maybe several errors.
Open the console (F12 in Chrome) to see what errors there are.

The error was a function make I declared it wrong. Thanks for the error view
