How do you detect if a part is movable?

I want to be able to detect if a part is able to be pushed around, aka a part that is not anchored and not welded to an anchored part. I need to do this so I can add these parts to my ignore list in my anti-noclip script. I want unanchored parts that are welded to each other (they can still move) to be ignored, but I want immovable parts (unanchored parts welded to anchored parts) to not be ignored. Is this possible? (Also, I’ve tried checking to see if Velocity.Magnitude>0, that doesn’t work. Physics of the part are updated on the client before they are on the server.)

local function is_movable(part)
    return #part:GetJoints() == 0 and not part.Anchored
end

There you go. When you weld a part to another it will create a joint, so part:GetJoints() would return the table of those joints, so if its length 0 it isn’t connected to anything, and of course if it’s not anchored it can move.

This works if there is no weld in the unanchored part?

There would be a joint created when it is welded, if it isn’t welded to anything there is no joints

There is just one issue with checking for joints.

An unanchored part welded to another unanchored part is not ignored since it has joints.

part:IsGrounded() will return if the part is anchored or attached to solid assembly that is anchored.

Using

if part:IsGrounded()==false then

works perfectly. You saved the day.
