    I have just tried to add touch input to the LunarLander example (to move the lander to wherever you touch on the screen for testing purposes), and for some reason the y axis is reversed for touch. What I mean by this is: if I touch the top of the screen, the lunar lander jumps to the bottom, if i touch the bottom it jumps to the top, and if i touch the middle it jumps to the middle. X axis is fine.

    It can't just be a -Y axis somewhere as that would be off-screen. Any idea what would cause this? I cannot figure it out for the life of me...

    The coordinates for the y axis start at 0 for the top of the screen and increase as you go down the screen. Basically the top left corner is the origin.
