Recently i've been investigating possibilities for the creation of the HUD for a game. I found out that Riot Games, for League of Legends, apparently uses Adobe Air for their Heads up Display.
Firstly, how could i go about doing this? I own a copy of Flash professional, so it's more a matter of getting it out of flash, and into the game. I am working with OpenGL in C++.
Secondly, how effective would it be? (Are alpha-blending issues a common problem, or messy edges, etc.)
