SurfaceType (Enum)

The SurfaceType Enum for the surface property has 9 numbers:
Enum Name Description
0 Smooth Does not form a bond with any other surface, except Weld.
1 Glue Forms a loose bond with other surfaces.
2 Weld Forms a strong bond with other surfaces.
3 Studs Only forms a weld-like bond with inlet surfaces.
4 Inlet Only forms a weld-like bond with studded surfaces.
5 Universal Forms weld-like bonds with Weld, Studs, Inlet and itself.
6 Hinge Forms a hinge-like bond with other surfaces, with free movement.
7 Motor Forms a hinge-like bond with other surfaces, without free movement. A motors behavior depends on the surface input.
8 SteppingMotor Same as Motor.
9 Unjoinable Will prevent ROBLOX's building tools and the studio's built-in tools, as well as some user-made tools, from creating joints between parts using this surface. Excluding this particularity, this surface type currently works like the Smooth SurfaceType.

The following table explains how SurfaceTypes work:

Surface Types
SurfaceType Weld Universal Studs Inlet Glue Smooth Unjoinable
Weld Weld Weld Weld Weld Weld Weld Weld
Universal Weld Snap Snap Snap Glue No Joint No Joint
Studs Weld Snap No Joint Snap Glue No Joint No Joint
Inlet Weld Snap Snap No Joint Glue No Joint No Joint
Glue Weld Glue Glue Glue Glue Glue Glue
Smooth Weld No Joint No Joint No Joint Glue No Joint No Joint
Unjoinable Weld No Joint No Joint No Joint Glue No Joint No Joint

Notes

  • The Unjoinable SurfaceType currently acts like the Smooth SurfaceType, but it might in the future not form joints with any surface. This is currently being debated by the admins.
