Ah. That makes the question more clear. Are you targeting something that has an extremely limited amount of RAM? If not, storing all of the UI elements in an array, and 'turning' them on and off via a class variable ( bool, I'd think ) should save you draw calls. You might want to edit in what platform and programming language you are targeting ( as tags as well, perhaps? ) to give people a little more knowledge as to your situation.

I'm not sure what language you're using, but I know that most languages have some sort of managed List or Vector that will tell you it's .size or .length. Regardless, if the List is storing textures, wouldn't you know exactly how many textures are in it ( i.e. you have to load them all in anyways, right?) ? Member int or float that increments every time a new texture is loaded will fix that problem.

| Aug 16, 2012 at 8:08 | comment | added | bonzairob | @Phill.Zitt I'd thought of that but the number of elements would be an issue. Things will be changing a lot in this system, but you need to know how many elements are in the list to start with. I suppose I could set it to a high number and pad it... | |

| Aug 15, 2012 at 23:26 | comment | added | Phill.Zitt | Do you have to switch textures inside of the Shader? Perhaps store a list of Textures, and inside of the object ( your objects have their own class, right? ) store an int relative to which Texture it uses, then use that to set the Texture during the draw call. | |
