## プロパティ

- `LinearVelocity.ForceLimitMode: ForceLimitMode`：Determines how the constraint force will be limited.
- `LinearVelocity.ForceLimitsEnabled: boolean`：Determines if the constraint force will be limited or if the physics solver can apply an unlimited force to achieve the target velocity.
- `LinearVelocity.LineDirection: Vector3`：The normalized Vector3 direction for constraining the velocity along a line.
- `LinearVelocity.LineVelocity: float`：Float value of the velocity when Class.LinearVelocity.VelocityConstraintMode|VelocityConstraintMode is set to Enum.VelocityConstraintMode|Line.
- `LinearVelocity.MaxAxesForce: Vector3`：Maximum force along each axis that the constraint can apply to achieve the vector velocity. Only used if Class.LinearVelocity.ForceLimitsEnabled|ForceLimitsEnabled is true, Class.LinearVelocity.ForceLimitMode|ForceLimitMode is Enum.ForceLimitMode|PerAxis, and Class.LinearVelocity.VelocityConstraintMode|VelocityConstraintMode is Enum.VelocityConstraintMode|Vector.
- `LinearVelocity.MaxForce: float`：Maximum magnitude of the force vector the constraint can apply.
- `LinearVelocity.MaxPlanarAxesForce: Vector2`：Maximum force along each axis that the constraint can apply to achieve the plane velocity. Only used if Class.LinearVelocity.ForceLimitsEnabled|ForceLimitsEnabled is true, Class.LinearVelocity.ForceLimitMode|ForceLimitMode is Enum.ForceLimitMode|PerAxis, and Class.LinearVelocity.VelocityConstraintMode|VelocityConstraintMode is Enum.VelocityConstraintMode|Plane.
- `LinearVelocity.PlaneVelocity: Vector2`：Vector2 value of the velocity in each tangent direction of the plane.
- `LinearVelocity.PrimaryTangentAxis: Vector3`：The primary axis in the plane, when Class.LinearVelocity.VelocityConstraintMode|VelocityConstraintMode is set to Enum.VelocityConstraintMode|Plane.
- `LinearVelocity.ReactionForceEnabled: boolean`：Determines whether an equal and opposite reaction force is also applied to the assembly of Class.Constraint.Attachment1|Attachment1 when Class.LinearVelocity.RelativeTo|RelativeTo is Enum.ActuatorRelativeTo|Attachment1.
- `LinearVelocity.RelativeTo: ActuatorRelativeTo`：Sets the ActuatorRelativeTo property for the constraint.
- `LinearVelocity.SecondaryTangentAxis: Vector3`：The secondary axis in the plane, when Class.LinearVelocity.VelocityConstraintMode|VelocityConstraintMode is set to Enum.VelocityConstraintMode|Plane.
- `LinearVelocity.VectorVelocity: Vector3`：Vector3 velocity value when Class.LinearVelocity.VelocityConstraintMode|VelocityConstraintMode is set to Enum.VelocityConstraintMode|Vector.
- `LinearVelocity.VelocityConstraintMode: VelocityConstraintMode`：The mode of the constraint.
