Mixing
Functions, and Image importing
I'm working on a project in game development in Javascript and HTML5 canvas. I have this common code I use for loading sprites:
var sprite = new Image();
sprite.src = "sprite.png";
I was wondering if there was a simpler way to do this, which I first thought by function, but not sure how I should do so. I would think to do so like this:
function loadSprite(src) {
this.src = src;
}
var loadSprite(sprite.png);
However I don't think this is the right way to do it. Could someone correct my code and/or give a simpler way of loading an image like this? (I am also using a ctx.drawImage(..., sprite) in order to change coordinates on the canvas so it needs an x,y,width,and height parameters in one way or another)

Why not use as below:
function loadSprite(src) {
var sprite = new Image();
sprite.src = src;
return sprite
}
var _local_var = loadSprite('sprite.png');
