Project Context
Class project submitted during graduation course at Universidade Lusofona - ULHT.
Project developed partnering with a school for kids with hearing disabilities. During planning phase, one of the needs expressed by the partners was that the students found it was a chalenge to learn how to use cash.
Kids would sometimes bring cash to buy snacks during break time, but could not yet transfer knowledge of math to the "real world" of coins and bills where 10 can be worth less than 5 or 2.
Understanding how a 10 cents coin is worth less than a 2 euros coin or a 5 euros bill was not as straight forward, so we presented this game as a means for making things more visual. Game mechanics includes serving clients a snack and selecting the correct change at checkout.
Integrated with the project was an external console built with a 3d printer and Arduino components, as seen below (the green gadget pictured on the left)
Code Features
Originally coded for Unity version 2017.x. Might not follow the most current practices and features of the engine.
I was surprised Unity version 2020.3 actually was able to restore this one and game is still working all right.
When using this project scripts for your own game, you would need to replace missing graphics and possibly edit to exclude some of the extra resources I had on the scenes, though.

- Player must identify how much each coin/bill is worth
