I'm doing a 2d simple shooter platformer, and for that i need a tile map. I'm pretty rusty on javascript, but i'm trying my best to do the game. I have a tile map done already this is the outcome that i want for the first lvl:
Tiled image of the first lvl, the wanted result:
And this is what I'm getting:
my code for the tile map is this one:
window.onload = function () {
var canvas = document.getElementById("canvas");

var cols = 25;
var rows = 18;
var tileWidth = 32;
var tileHeight = 32;
canvas.width = cols * tileWidth;
canvas.height = rows * tileHeight;
var map = [

I have one more function (animate), for drawing the map and the other assets and animations.
I just wanted to know what i have to do to get the expected result. I'm overheating on this for 2 days now, i tried severall ways to do it, but none works :(
