You can go into project and set: Initial Accelerations Initial Velocities e: Coefficient of restitution (kind of stickiness, from 0 to 1). 1 = perfect bounce and 0 = very sticky theta: Angle of inclination
This was never completed lol. Will make a better version in future 17/4/2020 : Started making 18/4/2020 : Added incline and brain fried due to calculations 19/4/2020 : Incline related Bugs fixed
