UID/IID Use!??

I am confused about the usage of IID and UID at runtime.

Basically i need to destroy an object's instance(out of multiple instances) using a button.

Every time i click the object and then click the destroyer button the object's last clicked instance should be destroyed.

I am not sure how to use IID or UID for 'picking' and then destroy the object.

One way to do it would be this:

variable lastTouched

On object clicked

.. set lastTouched : object.UID

On button clicked

pick object by UID lastTouched

.. object destroy

So every time you click on object you save the objects UID to a variable. When a button is pressed, we pick the object indicated in variable and destroy it.

Thanx.It worked.
