A PrismaticConstraint creates a rigid joint between two Attachments, allowing them to slide along one axis but not rotate. This constrains the attachments so that their X axes are collinear but pointing in opposite directions. It also constrains the attachments so that their Y axes are parallel.
This constraint inherits many properties from SlidingBallConstraint including ActuatorType, LimitsEnabled, Velocity, and more. Please refer to SlidingBallConstraint for details on configuring a PrismaticConstraint.
When configuring this constraint, it may be helpful to study Roblox Units to understand how Roblox units compare to metric units.
