[Share] Script Handlers

B1ggBoss · July 5, 2010

This isnt an event, nor a fantastic npc or voiced command

Its an abstract engine which will allow you to add customize code to many parts of the game where only core mod was the way.

With this, you can modify the most used core parts without touch it (which reduce sync problems)

PD: The code there in the script is just a sample so you can follow it to do whatever you want

PD2: Ofc, the engine can be extended to be called in more placed according to your needs

Core patch
