Inventory help

Hi All

Im in the planning stages of a game, point and click style from a first person perspective… think CSI games for a reference.

Im looking into making an inventory. Its basically a row of empty slots that are filled from left to right as you find and click a retreivable item in the game environment.

I was thinking that each slot could be referenced in an array, and as each slot is filled a var increases the array target.

However, after some thought I asked myself, what happens when an object gets taken from the inventory from a low down slot (by dragging and dropping into play area), how can i make all items to the right of the used object shift to the left to fill the gap.

And heres where you come in, any ideas? Tutorials?

Any good point & click game creation tutorials in general?

much appreciated.
