Or were you in need of canceling your previous actor's action to change the item the actor is going to consume next?
Then this scriptlet is for you!

Bug Fix Available!

After receiving a weird report concerning the item selection process, I started working on the issue described there and found out that I just needed to move the cancellation of the item counter to another method. Now it works as first intended.

[kyonides]

Second Bug Fix Available!

I had to revisit my code a second time and I noticed that I might have skipped an actor when clearing the item count. Who could it be? Well, it'd be the last actor selected by the player for sure.

Now it should only trigger the buzzer SE when you truly picked the last available item in your party's bag.

VX ACE, You Have Not Been Forgotten!

From now on, all VX ACE users can take advantage of this easy-to-use battle item count script.
Yes guys, it's fully  automated just like its elder sibling.

Minor Bug Fix Has Arrived!

I had not noticed before how heroes could easily select any given item even after the item counter had hit the 0 limit. Version 1.0.4 gets rid of this exploitable bug for good.

By the way, my fellow RMXP users, the script has been ported to RGSS1 as well!
