What is a Motar6D?

Please note: I am unsure if this is in the correct category. If it is not, please inform me in the reply area.

I have been using WeldConstraints a lot in ROBLOX Studio and I cam across something new called a ‘Motor6D’.

I have no idea what these are and how they are used so I have come to the DevForum as always to figure out what they are!

If there are any useful links feel free to post them too.

You can always look up any Roblox class on the wiki: Motor6D | Documentation - Roblox Creator Hub

Motor6D joins two BasePart ( Part0 and Part1 ) together in an animatable way. The Transform property determines the offset between these parts. This can be set manually using RunService.Stepped or through an Animator . Models whose parts are joined by Motor6D are usually referred to as rigs, typically for Humanoid s. There are two primary kinds of rigs for Player avatars: R6 and R15.

So they’re mostly used for animations. They’re essentially identical to Weld objects: Weld | Documentation - Roblox Creator Hub

… which are completely different to WeldConstraints WeldConstraint | Documentation - Roblox Creator Hub

… which don’t have C0 or C1 properties, and so has no effect on the relative CFrames of the affected parts, other than keeping them fixed relative to each other.

Oh that’s another question I had to ask someone. What’s the difference between a Weld and a WeldConstraint?

It’s really easiest to just check the respective wiki pages, but AFAIK there’s no difference other than what I explained.
