# 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.
