Preface
This is just a quick guide of how to make a working HUD.
First of all, there are some concepts you should know about HUD (everything detailed on HUD wikipage):
Fields: Used to show numbers/text/graphics (can show also item/character graphics).
Timers: Update HUD information (this concept is only for interfaces) or Global timer.
Objects: Show a graphic stored on Effect resources.
IMPORTANT NOTE: To access anything related to a HUD, it must be turned ON before everything.
