Dealing out an ID value based on X position?

[Outcast]

Is there a way to automatically sort an ID in some instances of identical objects based on their X position? So the object furthest to the left gets an ID of "0" the object with the next lowest X pos gets id "1" and so on?

I needed to do a similar thing but from top to bottom. I'm sure my approach wasn't the most optimized it could be, but i got it to work. It required two nested loops, one to loop through the width of the screen (for your example), 0-???, then a loop of each object to see if its X coordinate matched the index for the Screen Width Loop. Prior to launching either loop, set global variable for Rank, and set that to 0. If you have an object where the x coordinate matches index for screen width loop, set that object's alterable value to Rank, and add 1 to rank.

In the future, I'm going to replace my system like this with something based on a bubblesort algorithm that Chris Burrows put together. I can't find it now, but I'll try to post a link to that later on...

Here's an example file of the nested loop I was talking about. The actives are drag and droppable, click rank em to assign values based on x position. I would be interested to hear how others might optimize this, as it is cycling through a lot of loops.

Thanks for the example!
