During this last two weeks i've been working in a AR game with some classmates. This is our second game as OPAL.
In brief words it's a tower defense game, where you battle against robots in a determined time frame (depends on the difficulty selected).
My task was to code the game while learning how AR elements are implemented in mobile games. It's a basic game concept but it works really well.
I'm leaving some lines of code down here like the title camera movement with the phone rotation, the AR lector and how you can destroy enemies touching the screen.
