Using WiiChuck with 3D Bounce

Using WiiChuck with 3D Bounce

in Integration and Hardware • 2 years ago

Hi! I'm new to Processing and I've been trying to modify this code here to work with the WiiChuckClass (for the Wii Nunchuk) using Arduino.

I've managed to get the ball moving around using the Nunchuk but when I move left the ball goes right and vice versa. Also, the ball's movements are restricted and I don't know which parts of the code to change to make the ball move anywhere :S

I was wondering if anyone here could give me any advice or suggestions on how to change the code below.

Thanks for your time :)
