Works against gravity and friction to maintain a minimum displacement and target velocity between it's two attachments.

• Attachment0 is point on the character part with Attachment.Axis pointing downwards in the direction of gravity.
• Attachment1 is point on the ground, with Attachment.Axis pointing in the direction of the surface normal, out from the part.

LevitationConstraint provides a simplified model of the way humanoid locomotion works.

In general humans can only apply forces upwards against the ground, with only gravity to pull them downwards. If you accelerate past a certain velocity at any point you will leave the ground. This constraint accounts for that and moves towards the target height without overshooting by targeting a velocity along the same axis as gravity will be 0 at the target height.

Human locomotion is provided by friction between your feet and the ground. This constraint also tries to maintain a relative velocity defined by LevitationConstraint.MotorVelocity along the ground plane by applying forces against the ground part, bounded by friction.

LevitationConstraint doesn't currently do any orientation. You'll still need another constraint to keep the character upright.

Warning: LevitationConstraint is likely to change dramatically soon. It probably doesn't make sense as a Constraint instance, and will probably be replaced with something shape-based that finds its own footholds.
