This basically works just like games using the D20 system (like Dungeons & Dragons).
You go to an NPC and talk to him while having Z pressed down. If you don't hold Z, then you just talk to him.

Creating variables
Create variable PickpocketRoll (this is a random number determining how good you go each time you pickpocket).
Create variable PickpocketSkill (this is a bonus to the number above).

Creating a "pickpocketable" NPC
Create a common NPC.
Add a conditional branch: If button Z is being pushed.
--->When false, then create a dialogue that will be showing up (normal talking with the NPC).
--->When true, then see the steps below.

Picking pockets
Control variable PickpocketRoll, random (set 1~20).
Control variable PickpocketRoll, add PickpocketSkill to PickpocketRoll.
--->If PickpocketRoll is less than 12, then the attempt is a fail.
--->If PickpocketRoll is equal or greater to 12, then you manage to steal an item
After pickpocketing, never forget to set PickpocketRoll to 0!


I know I'm not good at explaining, there's a playable tutorial/demo below.

Good and simple idea, thanks.

A simple and effective way to do this.Impressive.

Great idea, I'm definately going to use this in my game

Nice system, everything's in place. It reminds me of Star Ocean 2's pickpocketing item. Forgot what it's called, but it executes the pickpocketing similarly.
