The three virtues of a programmer: Laziness, Impatience, and Hubris. – Larry Wall
Please avoid editing or moving it and improve Kismet instead.
Kismet is the Visual Coding Software included in Unreal Editor 4. It greatly enhances in-editor coding that was available in previous Unreal Editors.
The basic concept is similar to previous UEd's Scripted Triggers but hugely more complicated and you do not need huge numbers of actors to follow multiple sequences of code!
The visual aspect has a flowchart style where individual components can be linked together in various ways.
Main Components and Types
When using the Kismet, you are unable to actually edit the code. You would have to save your work and then edit your code later in a text-based editor such as notepad.
