Dodging Block
A block dodging game where you steer a green block left and right using tilt input to avoid falling obstacles and score points.
Introduction
This is a fast-paced dodging game, You control a green car at the bottom of the screen, and your objective is to avoid incoming yellow obstacles falling from the top.
To start the game, press any button. Once the game begins, tilt the device (or move the joystick) left or right to steer your car across the track. The car stays within the road boundaries marked in red. Obstacles appear randomly and move downward; if your car collides with them, the game ends. Your score increases each time you successfully dodge a set of obstacles.
Programming Design
Source Code
By default, your device comes with the necessary firmware and libraries preinstalled. If you have modified or replaced the firmware or libraries, make sure the following files are present (download if need by click the link)
Below is the main program file along with any additional files required for this specific app.
