Spritedefinitions returning zero

[fxfx]

I am trying to get a list of all sprite names in a Sprite Collection during runtime. I put the data file in Resources folder, and then try to get all the names by code:

tk2dSpriteCollectionData atlas = Resources.Load("atlas", typeof(tk2dSpriteCollectionData)) as tk2dSpriteCollectionData;

foreach (tk2dSpriteDefinition spritedefinition in atlas.spriteDefinitions) {
           Debug.Log(spritedefinition.name);
}

The weird thing is that it works for one Sprite Collection, and not the other. The other Sprite Collection is showing 0 spriteDefinitions count.
I checked and the only difference between the two Sprite Collection is that the one returning 0 has 3 platforms (@1x, @2x, @4x)

Any help will be appreciated. Thanks!

If it has platforms, you should use atlas.inst.spriteDefinitions. That will return the loaded platform collection. In fact you can safely do that all the time.

It works. Thanks!
