Syntax

ball free keyword ... <range>

Primary keywords:

spin    spin-x    spin-y    spin-z    velocity    velocity-x    velocity-y    velocity-z

Free the specified ball velocities. As a result, ball motion reflects the forces acting upon them.

spin

The angular velocity is free.

spin-x (3D ONLY)

Free the \(x\)-component of the angular velocity.

spin-y (3D ONLY)

Free the \(y\)-component of the angular velocity.

spin-z (3D ONLY)

Free the \(z\)-component of the angular velocity.

velocity

The translational velocity is free.

velocity-x

Free the \(x\)-component of the translational velocity.

velocity-y

Free the \(y\)-component of the translational velocity.

velocity-z (3D ONLY)

Free the \(z\)-component of the translational velocity.

Usage Examples

Free velocity and spin of all balls.

ball free velocity spin

Free velocity in the \(x\)-direction for all balls in the group left_balls.

ball free velocity-x range group 'left_balls'
