Description

A RopeConstraint prevents two attachments from separating further than a defined Length. The attachments can move closer together than this length and both can freely rotate. This constraint can also be powered to behave as a motorized winch.

When configuring this constraint, it may be helpful to study Roblox Units to understand how Roblox units compare to metric units.

Winch

If a rope's WinchEnabled property is enabled, it attempts to translate the attachments to a set separation specified by WinchTarget, effectively the target length of the rope in studs. This translation is controlled by WinchSpeed, WinchResponsiveness, and WinchForce.

Note that WinchSpeed must be a positive value, used to either contract or extend the rope length to WinchTarget. Setting a negative speed will revert to 0, not reverse the winch servo direction.
