var ctx = canvas.getContext("2d");

characterRight.src = "player-right.png";
var characterLeft = new Image();
characterLeft.src = "player-left.png";
var characterUp = new Image();
characterUp.src = "player-up.png";
var characterDown = new Image();
characterDown.src = "player-down.png";

// Tile images
var grass = new Image();
grass.src = "grass.png";
var dirt = new Image();
dirt.src = "dirt.png";

// Defines the player object
var player = {
    startX: …
