Thanks guys!
The trigger is like the black sheep and I have no clear ide on how to make it work on its own.... In my game you shoot bullets with the right trigger and Ill probably end up doing a pixelated text saying "Right Trigger" instead. The only reference I have is my own gamepad and I refuse to look at how others have solved this... Feels like Im making excuses but I should probably have said this in the topic start.
About the AA of the edges, all the buttons are going to be more or less like icons and needs to have a transparent background and if I make them AAed wouldn´t I need another color to blend of with and by that give them an edge of that color?
Semi transparent black maybe... but that probably means that I have to put a mask of some other bitmap over it in the game...
Hope someone know...
Edit: Did a quick version of the right trigger-text I talked about, below the buttons in this mock:
