Food Fortress was an experimental prototype I created with three other students at Bath Spa University, which sought to gamify the process of purchasing healthy food. The basic idea was that the player could use a QR code scanner built into the game to scan shopping receipts from participating retailers. The player would then be rewarded with in-game currency, the amount of which is determined by the number of 'healthy' items (such as fruit and vegetables) they have purchased. This currency is vital to progress in the game, as it is required to build and upgrade structures, and so the player is incentivised to purchase healthier food in order to expand their kingdom.
As the direct implementation of a QR code scanner into the game was beyond our expertise at the time, we instead opted to utilise a Unity plugin which communicated with a third party QR code scanning app.
When the player presses the 'scan' button, they are taken to the app, and prompted to scan their QR code. Doing so will immediately return the player to the game and award them with 8 build points. The points can then be used to build structures and upgrade the settlement.
Of course, the obvious downside to this solution is the reliance on a third party application, the availability and compatibility of which is not permanently guaranteed. For the purposes of this prototype, however, it was determined to be an appropriate compromise.
