Description

Pokemon Safari is the ULTIMATE Pokemon experience. Compete with friends as you try to catch the most Pokemon in a brand new Safari Zone. This Safari Zone isn't similar to any previous safaris you've been to; many rare and legendary Pokemon call this safari home such as the Legendary bird trio, Articuno, Zapdos and Moltres! With only 30 pokeballs, rocks, and bait at your disposal, you need to be careful with how you use your items,

Gameplay: While the game is running, connect your phone to the mbed using the Adafruit Bluetooth BLE module and use Adafruit's Bluetooth app to stream your phone's Quaternion data to the mbed. Then by tilting your phone, you can move your cursor on the screen to take aim at any Pokemon on screen. By using two pushbuttons connected to your mbed, you can then cycle through your inventory, choose your items, and then throw them on screen.

Parts used: Adafruite Bluefruit LE, 2 pushbuttons.

Game

The game was developed using Unity. The framework can be downloaded from unity3d.com The mbed is interfaced through the serial port of the computer (COM3 in our case). The computer receives quaternion data via the COM port from the mbed. The data is sent in a specific way in order to correctly process and move the player's cursor. Unity handles all of the games physics and intelligence as long as C# logic is provided. The following scripts are composed of the C# logic we used to implement Pokemon Safari.
