Version control for spritesheet images using Loader pre

[Rob Gordon]

This is really more of a comment than a question since I needed a solution for version-controlling a spritesheet and couldn't see a straightforward way of doing it.

To version-control the json file, I do this:

var file = [{name:"ui", url:"ui.json?v=1"}]

Now, the PIXI Loader will automatically load the image file and internally append "_image" to its name...but it will *not* carry over the "?v=1" part to the url.

A solution to this problem is to use the 'pre' middleware to modify the url of the file, as follows:

Loader
        .add(file)
        .pre(preProcessor)
        .load();

function preProcessor(resource, next) {
    if (resource.name == "ui_image") {
        resource.url = resource.url.split("?")[0] + "?v=1";
    }
    next();
}

I'll leave this here for further comment or as an example of a working solution to this kind of problem.

Yeah, ewhen we intgrate resource-loader v4 there will be special "url resolver" thingy for it

Good to know! Is that a 5.4 feature or a v6 feature?

5.5 probably.
