SpringConstraint
A SpringConstraint applies a force to its Attachments based on spring and damper behavior. This constraint, along with a CylindricalConstraint, is ideal for building vehicle suspension.
Note that if this constraint attaches one part (A) to another part (B) that is anchored or connected to an anchored part (Z), part A will not be locally simulated when interacting with a player.
When configuring this constraint, it may be helpful to study Roblox Units to understand how Roblox units compare to metric units.
Free Length
FreeLength defines the natural resting length of the spring. If the attachments are further apart than the free length, they are forced together; if the attachments are closer together than the free length, they are forced apart.
Damping
The Damping value controls how fast the spring's oscillation dies down. A value of 0 allows the spring to oscillate endlessly, while higher values bring the spring to a rest more quickly.
Stiffness
Stiffness sets the strength of the spring. Higher values create a spring that responds with more force when its attachments are closer together or further apart than FreeLength.
Limits
Enabling the LimitsEnabled property exposes the MinLength and MaxLength values for setting the minimum and maximum length of the spring. If the spring's attachments reach these limits, they stop moving apart from one another without restitution.
Summary
Properties
The number of coils visualized on the SpringConstraint.
The current distance between the constraint's Attachments.
Damping constant for the SpringConstraint. Multiplied to the velocity of the constraint's Attachments to reduce the spring force applied.
Natural resting length of the spring.
Sets whether the SpringConstraint enforces a minimum and maximum length.
The maximum force the SpringConstraint can apply on its Attachments.
The maximum separation the SpringConstraint will allow if LimitsEnabled is true.
The minimum separation the SpringConstraint will allow if LimitsEnabled is true.
The visualized radius of the spring's coils.
The strength of the spring. The higher this value the more force will be applied when the attachments are separated a different length than the FreeLength.
The visualized thickness of the spring's coils.
Properties

The Attachment that is connected to Constraint.Attachment0.
The color of the constraint.
Toggles whether or not the constraint is enabled.
Toggles the constraint's visibility.
