AssetManager, getTextures, wrong sorting (now only alphabetic, need to be alphabetic/numeric)

[corcimaria]

if i have resources image_1 ... image_14,

var out:Vector.<String> = new <String>[];
for (var u:Number = 1; u < 15; u++) {
 out.push("image_" + u);
 }

out.sort(Array.CASEINSENSITIVE);
trace(out); 
// image_1,image_10,image_11,image_12,image_13,image_14,image_2,image_3,image_4,image_5,image_6,image_7,image_8,image_9

now Movieclip will play in wrong order frames

Mhm, the reason for that is that "Array.sort" doesn't support numeric sorting of strings. Typically, people simply add leading zeros to their image names, e.g. image_01, image_02, etc.

Would that be possible for you, as well?

[JohnBlackburne]

If you want them to sort in the expected order, you could add a zero before numbers less than 10, e.g.

out.push( _u < 10 ? "image0" + u : "image" + u);

if i add 0 before number, same results //image_01,image_010,image_011,image_012,image_013,image_014,image_02,image_03,image_04,image_05,image_06,image_07,image_08,image_09

i use custom sorting in getTextures, like:

var reA = /[^a-zA-Z]/g;
var reN = /[^0-9]/g;
function sortAlphaNum(a,b) {
    var aA = a.replace(reA, "");
    var bA = b.replace(reA, "");
    if(aA === bA) {
        var aN = parseInt(a.replace(reN, ""), 10);
        var bN = parseInt(b.replace(reN, ""), 10);
        return aN === bN ? 0 : aN > bN ? 1 : -1;
    } else {
        return aA > bA ? 1 : -1;
    }
}

and this work

[PrimaryFeather]

I wan't clear enough — please follow John's advice: the zero only needs to be added when the number is smaller than ten (i.e., 0-9).

[corcimaria]

yes, this work, tnx

[PrimaryFeather]

i use custom sorting in getTextures, like [...]

Yes, perhaps I should add such a method, too. On the other hand, the built-in sort doesn't create any temporary objects, which is an advantage for a long list of textures. Nevertheless: I agree, it would be nice not to have to fall back to such workarounds.

[PrimaryFeather]

Thanks for the heads-up, in any case!

[corcimaria]

when desigher save for me somting animation, i need any time add this 0, and this can be many times, when we check animation, not very comfortable.

[JohnBlackburne]

You can use the other behaviour of Vector.sort(), and not pass constant like Array.CASEINSENSITIVE but pass a function. Inside that function you can extract the numbers from the strings and compare them numerically.

[PrimaryFeather]

Yes, I could definitely do that — I put it on my TODO list!
