Indiana João

Platform: TIC-80

Description: Indiana João is a game I developed with my fellow students, featuring a unique control mechanism utilizing a Raspberry Pico and advanced programming techniques. The project highlights the integration of the C/C++ SDK, Fourier Fast Transform, and the TinyUSB library to create innovative audio-based controls.

Work

My part on the project was the concept of the game and the implementation of a HID through the Raspberry Pico with the use of the C/C++ SDK, Fourier Fast Transform, and the TinyUSB library to implement controls that requires the player to sing a certain note to do an action.

Check it out here.

• Raspberry Pico: Utilized as the main micro controller that behaves as a composite HID to process audio input where the algorithm analyzes sound and sends the output signals to the main pc as keyboard inputs.
• Sound wave analysis with Fourier Fast Transform (FFT): I utilized a library that had the part to collect and store the samples and analyzes them using the Fourier Transform equation. This is the library used, made by googol
• TinyUSB Library: This was the library used for pico to behave as HID and program the base input functions.

Innovative Controls:

• Jump: Frequencies of C (3rd and 4th octaves)
• Big Jump: Frequencies of E (3rd and 4th octaves)
• Slide: Frequencies of A (3rd and 4th octaves)

By focusing on these advanced technologies, Indiana João offers an engaging and unconventional gameplay experience, showcasing the potential of integrating hardware and software for interactive entertainment.
