# Learn Intermediate OOP by Building a Platformer Game - Step 25

### Tell us what’s happening:

Hi, I’m pretty sure this is a bug. Instructions say:

Create an empty `if` statement that checks if the sum of the player’s `y` position, height, and `y` velocity is less than or equal to the height of the canvas.

And as you can see in the code, I’ve placed them in a different order than it dictates, and it’s “wrong”. If you put them in that order, then it checks as the right answer.

``````/* file: script.js */
const startBtn = document.getElementById("start-btn");
const canvas = document.getElementById("canvas");
const startScreen = document.querySelector(".start-screen");
const checkpointScreen = document.querySelector(".checkpoint-screen");
const checkpointMessage = document.querySelector(".checkpoint-screen > p");
const ctx = canvas.getContext("2d");
canvas.width = innerWidth;
canvas.height = innerHeight;
const gravity = 0.5;
let isCheckpointCollisionDetectionActive = true;

const proportionalSize = (size) => {
return innerHeight < 500 ? Math.ceil((size / 500) * innerHeight) : size;
}

class Player {
constructor() {
this.position = {
x: proportionalSize(10),
y: proportionalSize(400),
};
this.velocity = {
x: 0,
y: 0,
};
this.width = proportionalSize(40);
this.height = proportionalSize(40);
}
draw() {
ctx.fillStyle = "#99c9ff";
ctx.fillRect(this.position.x, this.position.y, this.width, this.height);
}

// User Editable Region

update() {
this.draw();
this.position.x += this.velocity.x;
this.position.y += this.velocity.y;
if (this.velocity.y + this.position.y + this.height  <= canvas.height) {

}
}

// User Editable Region

}
