Amazing. I ever wanted to create one Terminator/Robocop/Futuristic HUD program, but without the world positioned holograms, a lot of triangulation work was necessary using OpenPeripheral Glasses.
Huh, I don't think you need methods to know where the player is looking at, as the OpenPeripheral's Sensor does the job pretty well.
This recipe for the roll has conflict with Tinkers' Construct's stack of paper.
And when I try to use .writeIn, it says "attempt to call field "writeIn" ( a nil value ), that means the callback is other, or do not works. I am using OC 1.3.0.465 and latest version of OpenPrinter.
