# Hand Follow
## Hand Follow
The `HandFollow` class is responsible for managing the physics-based movement of a hand object in Unity, ensuring it follows a target transform with specified constraints on movement and rotation. This class is designed to work with the `Hand` component and provides various settings for fine-tuning the following behavior.
#### Move to Settings
`Max Move To Distance` : The maximum allowed distance for moving to the target position.
`Max Move To Angle` : The maximum allowed angle for rotating to the target rotation.
`Max Follow Distance` : The distance at which the hand returns to the target if it gets stuck.
`Max Velocity` : The maximum allowed velocity of the hand.
#### Position Settings
`Follow Position Strength` : The speed at which the hand follows the target position.
`Start Drag` : The initial drag value of the hand.
`Drag Damper` : The drag multiplier to use when within a certain distance from the target.
`Drag Damper Distance` : The distance at which the drag damper starts to take effect.
`Min Velocity Change` : The minimum change in velocity for the hand.
`Min Velocity Distance Multi` : A multiplier for the minimum velocity change based on distance.
#### Rotation Settings
`Follow Rotation Strength` : The speed at which the hand follows the target rotation.
`Start Angular Drag` : The initial angular drag value of the hand.
`Angle Drag Damper` : The angular drag multiplier to use when within a certain angle distance from the target.
`Angle Drag Damper Distance` : The angle distance at which the angular drag damper starts to take effect.
#### Mass Settings
`Min Mass` : The minimum mass of the hand. If you want this to work like Auto Hand V3.3 and earlier, set the min mass equal to the max mass
`Max Mass` : The maximum mass of the hand.
`Held Mass Divider` : A divider to reduce the mass of held objects.
`Distance Mass Difference` : A factor to adjust the mass based on distance.
`Distance Mass Max Distance` : The maximum distance for mass adjustment.
`Angle Mass Difference` : A factor to adjust the mass based on angle.
`Angle Mass Max Angle` : The maximum angle for mass adjustment.
Internal Public Getters
`Last Angular Velocity` : The last recorded angular velocity of the hand.
`Last Velocity` : The last recorded velocity of the hand.
`Last Follow Delta Position` : The change in position since the last frame.
`Last Follow Delta Rotation` : The change in rotation since the last frame.
`Target Move To Position` : The target position to move to.
`Target Move To Rotation` : The target rotation to move to.
